Product Description

Specifications of Bearing

Product Description of angular contact ball bearing

Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.
The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from 1 raceway to another, and a line perpendicular to the bearing axis.

     The most commonly used designs are:

  • single row angular contact ball bearings.
  • double row angular contact ball bearings.
  • four-point contact ball bearings
  • Applications:

    Single row angular contact ball bearings: machine tool spindles, high frequency motors, gas turbines, centrifuges, small car front wheel, differential pinion shaft, booster pumps, drilling platforms, food machinery, dividing head, fill welder, low-noise cooling towers, electrical and mechanical equipment, painting equipment, machine slot board, arc welding machine.
    Double row angular contact ball bearings: pump, blower, air compressor, various types of transmission, fuel injection pumps, printing machinery, planetary reducer, extraction equipment, cycloid reducer, food packaging machinery, welding machines, electric irons, square box, gravity gun, wire strippers, axle, test analysis equipment, fine chemicals, machinery.

What Are the Advantages of a Splined Shaft?

If you are looking for the right splined shaft for your machine, you should know a few important things. First, what type of material should be used? Stainless steel is usually the most appropriate choice, because of its ability to offer low noise and fatigue failure. Secondly, it can be machined using a slotting or shaping machine. Lastly, it will ensure smooth motion. So, what are the advantages of a splined shaft?
Stainless steel is the best material for splined shafts

When choosing a splined shaft, you should consider its hardness, quality, and finish. Stainless steel has superior corrosion and wear resistance. Carbon steel is another good material for splined shafts. Carbon steel has a shallow carbon content (about 1.7%), which makes it more malleable and helps ensure smooth motion. But if you’re not willing to spend the money on stainless steel, consider other options.
There are 2 main types of splines: parallel splines and crowned splines. Involute splines have parallel grooves and allow linear and rotary motion. Helical splines have involute teeth and are oriented at an angle. This type allows for many teeth on the shaft and minimizes the stress concentration in the stationary joint.
Large evenly spaced splines are widely used in hydraulic systems, drivetrains, and machine tools. They are typically made from carbon steel (CR10) and stainless steel (AISI 304). This material is durable and meets the requirements of ISO 14-B, formerly DIN 5463-B. Splined shafts are typically made of stainless steel or C45 steel, though there are many other materials available.
Stainless steel is the best material for a splined shaft. This metal is also incredibly affordable. In most cases, stainless steel is the best choice for these shafts because it offers the best corrosion resistance. There are many different types of splined shafts, and each 1 is suited for a particular application. There are also many different types of stainless steel, so choose stainless steel if you want the best quality.
For those looking for high-quality splined shafts, CZPT Spline Shafts offer many benefits. They can reduce costs, improve positional accuracy, and reduce friction. With the CZPT TFE coating, splined shafts can reduce energy and heat buildup, and extend the life of your products. And, they’re easy to install – all you need to do is install them.
splineshaft

They provide low noise, low wear and fatigue failure

The splines in a splined shaft are composed of 2 main parts: the spline root fillet and the spline relief. The spline root fillet is the most critical part, because fatigue failure starts there and propagates to the relief. The spline relief is more susceptible to fatigue failure because of its involute tooth shape, which offers a lower stress to the shaft and has a smaller area of contact.
The fatigue life of splined shafts is determined by measuring the S-N curve. This is also known as the Wohler curve, and it is the relationship between stress amplitude and number of cycles. It depends on the material, geometry and way of loading. It can be obtained from a physical test on a uniform material specimen under a constant amplitude load. Approximations for low-alloy steel parts can be made using a lower-alloy steel material.
Splined shafts provide low noise, minimal wear and fatigue failure. However, some mechanical transmission elements need to be removed from the shaft during assembly and manufacturing processes. The shafts must still be capable of relative axial movement for functional purposes. As such, good spline joints are essential to high-quality torque transmission, minimal backlash, and low noise. The major failure modes of spline shafts include fretting corrosion, tooth breakage, and fatigue failure.
The outer disc carrier spline is susceptible to tensile stress and fatigue failure. High customer demands for low noise and low wear and fatigue failure makes splined shafts an excellent choice. A fractured spline gear coupling was received for analysis. It was installed near the top of a filter shaft and inserted into the gearbox motor. The service history was unknown. The fractured spline gear coupling had longitudinally cracked and arrested at the termination of the spline gear teeth. The spline gear teeth also exhibited wear and deformation.
A new spline coupling method detects fault propagation in hollow cylindrical splined shafts. A spline coupling is fabricated using an AE method with the spline section unrolled into a metal plate of the same thickness as the cylinder wall. In addition, the spline coupling is misaligned, which puts significant concentration on the spline teeth. This further accelerates the rate of fretting fatigue and wear.
A spline joint should be lubricated after 25 hours of operation. Frequent lubrication can increase maintenance costs and cause downtime. Moreover, the lubricant may retain abrasive particles at the interfaces. In some cases, lubricants can even cause misalignment, leading to premature failure. So, the lubrication of a spline coupling is vital in ensuring proper functioning of the shaft.
The design of a spline coupling can be optimized to enhance its wear resistance and reliability. Surface treatments, loads, and rotation affect the friction properties of a spline coupling. In addition, a finite element method was developed to predict wear of a floating spline coupling. This method is feasible and provides a reliable basis for predicting the wear and fatigue life of a spline coupling.
splineshaft

They can be machined using a slotting or shaping machine

Machines can be used to shape splined shafts in a variety of industries. They are useful in many applications, including gearboxes, braking systems, and axles. A slotted shaft can be manipulated in several ways, including hobbling, broaching, and slotting. In addition to shaping, splines are also useful in reducing bar diameter.
When using a slotting or shaping machine, the workpiece is held against a pedestal that has a uniform thickness. The machine is equipped with a stand column and limiting column (Figure 1), each positioned perpendicular to the upper surface of the pedestal. The limiting column axis is located on the same line as the stand column. During the slotting or shaping process, the tool is fed in and out until the desired space is achieved.
One process involves cutting splines into a shaft. Straddle milling, spline shaping, and spline cutting are 2 common processes used to create splined shafts. Straddle milling involves a fixed indexing fixture that holds the shaft steady, while rotating milling cutters cut the groove in the length of the shaft. Several passes are required to ensure uniformity throughout the spline.
Splines are a type of gear. The ridges or teeth on the drive shaft mesh with grooves in the mating piece. A splined shaft allows the transmission of torque to a mate piece while maximizing the power transfer. Splines are used in heavy vehicles, construction, agriculture, and massive earthmoving machinery. Splines are used in virtually every type of rotary motion, from axles to transmission systems. They also offer better fatigue life and reliability.
Slotting or shaping machines can also be used to shape splined shafts. Slotting machines are often used to machine splined shafts, because it is easier to make them with these machines. Using a slotting or shaping machine can result in splined shafts of different sizes. It is important to follow a set of spline standards to ensure your parts are manufactured to the highest standards.
A milling machine is another option for producing splined shafts. A spline shaft can be set up between 2 centers in an indexing fixture. Two side milling cutters are mounted on an arbor and a spacer and shims are inserted between them. The arbor and cutters are then mounted to a milling machine spindle. To make sure the cutters center themselves over the splined shaft, an adjustment must be made to the spindle of the machine.
The machining process is very different for internal and external splines. External splines can be broached, shaped, milled, or hobbed, while internal splines cannot. These machines use hard alloy, but they are not as good for internal splines. A machine with a slotting mechanism is necessary for these operations.

The Benefits of Spline Couplings for Disc Brake Mounting Interfaces

Spline couplings are commonly used for securing disc brake mounting interfaces. Spline couplings are often used in high-performance vehicles, aeronautics, and many other applications. However, the mechanical benefits of splines are not immediately obvious. Listed below are the benefits of spline couplings. We’ll discuss what these advantages mean for you. Read on to discover how these couplings work.

Disc brake mounting interfaces are splined

There are 2 common disc brake mounting interfaces – splined and six-bolt. Splined rotors fit on splined hubs; six-bolt rotors will need an adapter to fit on six-bolt hubs. The six-bolt method is easier to maintain and may be preferred by many cyclists. If you’re thinking of installing a disc brake system, it is important to know how to choose the right splined and center lock interfaces.

Aerospace applications

The splines used for spline coupling in aircraft are highly complex. While some previous researches have addressed the design of splines, few publications have tackled the problem of misaligned spline coupling. Nevertheless, the accurate results we obtained were obtained using dedicated simulation tools, which are not commercially available. Nevertheless, such tools can provide a useful reference for our approach. It would be beneficial if designers could use simple tools for evaluating contact pressure peaks. Our analytical approach makes it possible to find answers to such questions.
The design of a spline coupling for aerospace applications must be accurate to minimize weight and prevent failure mechanisms. In addition to weight reduction, it is necessary to minimize fretting fatigue. The pressure distribution on the spline coupling teeth is a significant factor in determining its fretting fatigue. Therefore, we use analytical and experimental methods to examine the contact pressure distribution in the axial direction of spline couplings.
The teeth of a spline coupling can be categorized by the type of engagement they provide. This study investigates the position of resultant contact forces in the teeth of a spline coupling when applied to pitch diameter. Using FEM models, numerical results are generated for nominal and parallel offset misalignments. The axial tooth profile determines the behavior of the coupling component and its ability to resist wear. Angular misalignment is also a concern, causing misalignment.
In order to assess wear damage of a spline coupling, we must take into consideration the impact of fretting on the components. This wear is caused by relative motion between the teeth that engage them. The misalignment may be caused by vibrations, cyclical tooth deflection, or angular misalignment. The result of this analysis may help designers improve their spline coupling designs and develop improved performance.
CZPT polyimide, an abrasion-resistant polymer, is a popular choice for high-temperature spline couplings. This material reduces friction and wear, provides a low friction surface, and has a low wear rate. Furthermore, it offers up to 50 times the life of metal on metal spline connections. For these reasons, it is important to choose the right material for your spline coupling.

High-performance vehicles

A spline coupler is a device used to connect splined shafts. A typical spline coupler resembles a short pipe with splines on either end. There are 2 basic types of spline coupling: single and dual spline. One type attaches to a drive shaft, while the other attaches to the gearbox. While spline couplings are typically used in racing, they’re also used for performance problems.
The key challenge in spline couplings is to determine the optimal dimension of spline joints. This is difficult because no commercial codes allow the simulation of misaligned joints, which can destroy components. This article presents analytical approaches to estimating contact pressures in spline connections. The results are comparable with numerical approaches but require special codes to accurately model the coupling operation. This research highlights several important issues and aims to make the application of spline couplings in high-performance vehicles easier.
The stiffness of spline assemblies can be calculated using tooth-like structures. Such splines can be incorporated into the spline joint to produce global stiffness for torsional vibration analysis. Bearing reactions are calculated for a certain level of misalignment. This information can be used to design bearing dimensions and correct misalignment. There are 3 types of spline couplings.
Major diameter fit splines are made with tightly controlled outside diameters. This close fit provides concentricity transfer from the male to the female spline. The teeth of the male spline usually have chamfered tips and clearance with fillet radii. These splines are often manufactured from billet steel or aluminum. These materials are renowned for their strength and uniform grain created by the forging process. ANSI and DIN design manuals define classes of fit.

Disc brake mounting interfaces

A spline coupling for disc brake mounting interfaces is a type of hub-to-brake-disc mount. It is a highly durable coupling mechanism that reduces heat transfer from the disc to the axle hub. The mounting arrangement also isolates the axle hub from direct contact with the disc. It is also designed to minimize the amount of vehicle downtime and maintenance required to maintain proper alignment.
Disc brakes typically have substantial metal-to-metal contact with axle hub splines. The discs are held in place on the hub by intermediate inserts. This metal-to-metal contact also aids in the transfer of brake heat from the brake disc to the axle hub. Spline coupling for disc brake mounting interfaces comprises a mounting ring that is either a threaded or non-threaded spline.
During drag brake experiments, perforated friction blocks filled with various additive materials are introduced. The materials included include Cu-based powder metallurgy material, a composite material, and a Mn-Cu damping alloy. The filling material affects the braking interface’s wear behavior and friction-induced vibration characteristics. Different filling materials produce different types of wear debris and have different wear evolutions. They also differ in their surface morphology.
Disc brake couplings are usually made of 2 different types. The plain and HD versions are interchangeable. The plain version is the simplest to install, while the HD version has multiple components. The two-piece couplings are often installed at the same time, but with different mounting interfaces. You should make sure to purchase the appropriate coupling for your vehicle. These interfaces are a vital component of your vehicle and must be installed correctly for proper operation.
Disc brakes use disc-to-hub elements that help locate the forces and displace them to the rim. These elements are typically made of stainless steel, which increases the cost of manufacturing the disc brake mounting interface. Despite their benefits, however, the high braking force loads they endure are hard on the materials. Moreover, excessive heat transferred to the intermediate elements can adversely affect the fatigue life and long-term strength of the brake system.

Multiple Grinding Process

The channel’s grinding is the most important process part for bearing. It can make the channel more smooth. We grind the bearing’s channel 4 or more times, but others may grind only 1 time. Because of the multiple grinding, our bearing’s Inner and outer race’s tolerance is very small, the chamfer is also very smooth.

Disc brake mounting interfaces that are splined

There are 2 common disc brake mounting interfaces, splined and center lock. Disc brakes with splined interfaces are more common. They are usually easier to install. The center lock system requires a tool to remove the locking ring on the disc hub. Six-bolt rotors are easier to install and require only 6 bolts. The center lock system is commonly used with performance road bikes.
Post mount disc brakes require a post mount adapter, while flat mount disc brakes do not. Post mount adapters are more common and are used for carbon mountain bikes, while flat mount interfaces are becoming the norm on road and gravel bikes. All disc brake adapters are adjustable for rotor size, though. Road bikes usually use 160mm rotors while mountain bikes use rotors that are 180mm or 200mm.
splineshaft

Disc brake mounting interfaces that are helical splined

A helical splined disc brake mounting interface is designed with a splined connection between the hub and brake disc. This splined connection allows for a relatively large amount of radial and rotational displacement between the disc and hub. A loosely splined interface can cause a rattling noise due to the movement of the disc in relation to the hub.
The splines on the brake disc and hub are connected via an air gap. The air gap helps reduce heat conduction from the brake disc to the hub. The present invention addresses problems of noise, heat, and retraction of brake discs at the release of the brake. It also addresses issues with skewing and dragging. If you’re unsure whether this type of mounting interface is right for you, consult your mechanic.
Disc brake mounting interfaces that are helix-splined may be used in conjunction with other components of a wheel. They are particularly useful in disc brake mounting interfaces for hub-to-hub assemblies. The spacer elements, which are preferably located circumferentially, provide substantially the same function no matter how the brake disc rotates. Preferably, 3 spacer elements are located around the brake disc. Each of these spacer elements has equal clearance between the splines of the brake disc and the hub.
Spacer elements 6 include a helical spring portion 6.1 and extensions in tangential directions that terminate in hooks 6.4. These hooks abut against the brake disc 1 in both directions. The helical spring portion 5.1 and 6.1 have stiffness enough to absorb radial impacts. The spacer elements are arranged around the circumference of the intermeshing zone.
A helical splined disc mount includes a stabilizing element formed as a helical spring. The helical spring extends to the disc’s splines and teeth. The ends of the extension extend in opposite directions, while brackets at each end engage with the disc’s splines and teeth. This stabilizing element is positioned axially over the disc’s width.
Helical splined disc brake mounting interfaces are popular in bicycles and road bicycles. They’re a reliable, durable way to mount your brakes. Splines are widely used in aerospace, and have a higher fatigue life and reliability. The interfaces between the splined disc brake and BB spindle are made from aluminum and acetate.
As the splined hub mounts the disc in a helical fashion, the spring wire and disc 2 will be positioned in close contact. As the spring wire contacts the disc, it creates friction forces that are evenly distributed throughout the disc. This allows for a wide range of axial motion. Disc brake mounting interfaces that are helical splined have higher strength and stiffness than their counterparts.
Disc brake mounting interfaces that are helically splined can have a wide range of splined surfaces. The splined surfaces are the most common type of disc brake mounting interfaces. They are typically made of stainless steel or aluminum and can be used for a variety of applications. However, a splined disc mount will not support a disc with an oversized brake caliper.

Analytical Approaches to Estimating Contact Pressures in Spline Couplings

A spline coupling is a type of mechanical connection between 2 rotating shafts. It consists of 2 parts – a coupler and a coupling. Both parts have teeth which engage and transfer loads. However, spline couplings are typically over-dimensioned, which makes them susceptible to fatigue and static behavior. Wear phenomena can also cause the coupling to fail. For this reason, proper spline coupling design is essential for achieving optimum performance.
splineshaft

Modeling a spline coupling

Spline couplings are becoming increasingly popular in the aerospace industry, but they operate in a slightly misaligned state, causing both vibrations and damage to the contact surfaces. To solve this problem, this article offers analytical approaches for estimating the contact pressures in a spline coupling. Specifically, this article compares analytical approaches with pure numerical approaches to demonstrate the benefits of an analytical approach.
To model a spline coupling, first you create the knowledge base for the spline coupling. The knowledge base includes a large number of possible specification values, which are related to each other. If you modify 1 specification, it may lead to a warning for violating another. To make the design valid, you must create a spline coupling model that meets the specified specification values.
After you have modeled the geometry, you must enter the contact pressures of the 2 spline couplings. Then, you need to determine the position of the pitch circle of the spline. In Figure 2, the centre of the male coupling is superposed to that of the female spline. Then, you need to make sure that the alignment meshing distance of the 2 splines is the same.
Once you have the data you need to create a spline coupling model, you can begin by entering the specifications for the interface design. Once you have this data, you need to choose whether to optimize the internal spline or the external spline. You’ll also need to specify the tooth friction coefficient, which is used to determine the stresses in the spline coupling model 20. You should also enter the pilot clearance, which is the clearance between the tip 186 of a tooth 32 on 1 spline and the feature on the mating spline.
After you have entered the desired specifications for the external spline, you can enter the parameters for the internal spline. For example, you can enter the outer diameter limit 154 of the major snap 54 and the minor snap 56 of the internal spline. The values of these parameters are displayed in color-coded boxes on the Spline Inputs and Configuration GUI screen 80. Once the parameters are entered, you’ll be presented with a geometric representation of the spline coupling model 20.

Creating a spline coupling model 20

The spline coupling model 20 is created by a product model software program 10. The software validates the spline coupling model against a knowledge base of configuration-dependent specification constraints and relationships. This report is then input to the ANSYS stress analyzer program. It lists the spline coupling model 20’s geometric configurations and specification values for each feature. The spline coupling model 20 is automatically recreated every time the configuration or performance specifications of the spline coupling model 20 are modified.
The spline coupling model 20 can be configured using the product model software program 10. A user specifies the axial length of the spline stack, which may be zero, or a fixed length. The user also enters a radial mating face 148, if any, and selects a pilot clearance specification value of 14.5 degrees or 30 degrees.
A user can then use the mouse 110 to modify the spline coupling model 20. The spline coupling knowledge base contains a large number of possible specification values and the spline coupling design rule. If the user tries to change a spline coupling model, the model will show a warning about a violation of another specification. In some cases, the modification may invalidate the design.
In the spline coupling model 20, the user enters additional performance requirement specifications. The user chooses the locations where maximum torque is transferred for the internal and external splines 38 and 40. The maximum torque transfer location is determined by the attachment configuration of the hardware to the shafts. Once this is selected, the user can click “Next” to save the model. A preview of the spline coupling model 20 is displayed.
The model 20 is a representation of a spline coupling. The spline specifications are entered in the order and arrangement as specified on the spline coupling model 20 GUI screen. Once the spline coupling specifications are entered, the product model software program 10 will incorporate them into the spline coupling model 20. This is the last step in spline coupling model creation.
splineshaft

Analysing a spline coupling model 20

An analysis of a spline coupling model consists of inputting its configuration and performance specifications. These specifications may be generated from another computer program. The product model software program 10 then uses its internal knowledge base of configuration dependent specification relationships and constraints to create a valid three-dimensional parametric model 20. This model contains information describing the number and types of spline teeth 32, snaps 34, and shoulder 36.
When you are analysing a spline coupling, the software program 10 will include default values for various specifications. The spline coupling model 20 comprises an internal spline 38 and an external spline 40. Each of the splines includes its own set of parameters, such as its depth, width, length, and radii. The external spline 40 will also contain its own set of parameters, such as its orientation.
Upon selecting these parameters, the software program will perform various analyses on the spline coupling model 20. The software program 10 calculates the nominal and maximal tooth bearing stresses and fatigue life of a spline coupling. It will also determine the difference in torsional windup between an internal and an external spline. The output file from the analysis will be a report file containing model configuration and specification data. The output file may also be used by other computer programs for further analysis.
Once these parameters are set, the user enters the design criteria for the spline coupling model 20. In this step, the user specifies the locations of maximum torque transfer for both the external and internal spline 38. The maximum torque transfer location depends on the configuration of the hardware attached to the shafts. The user may enter up to 4 different performance requirement specifications for each spline.
The results of the analysis show that there are 2 phases of spline coupling. The first phase shows a large increase in stress and vibration. The second phase shows a decline in both stress and vibration levels. The third stage shows a constant meshing force between 300N and 320N. This behavior continues for a longer period of time, until the final stage engages with the surface.

Misalignment of a spline coupling

A study aimed to investigate the position of the resultant contact force in a spline coupling engaging teeth under a steady torque and rotating misalignment. The study used numerical methods based on Finite Element Method (FEM) models. It produced numerical results for nominal conditions and parallel offset misalignment. The study considered 2 levels of misalignment – 0.02 mm and 0.08 mm – with different loading levels.
The results showed that the misalignment between the splines and rotors causes a change in the meshing force of the spline-rotor coupling system. Its dynamics is governed by the meshing force of splines. The meshing force of a misaligned spline coupling is related to the rotor-spline coupling system parameters, the transmitting torque, and the dynamic vibration displacement.
Despite the lack of precise measurements, the misalignment of splines is a common problem. This problem is compounded by the fact that splines usually feature backlash. This backlash is the result of the misaligned spline. The authors analyzed several splines, varying pitch diameters, and length/diameter ratios.
A spline coupling is a two-dimensional mechanical system, which has positive backlash. The spline coupling is comprised of a hub and shaft, and has tip-to-root clearances that are larger than the backlash. A form-clearance is sufficient to prevent tip-to-root fillet contact. The torque on the splines is transmitted via friction.
When a spline coupling is misaligned, a torque-biased thrust force is generated. In such a situation, the force can exceed the torque, causing the component to lose its alignment. The two-way transmission of torque and thrust is modeled analytically in the present study. The analytical approach provides solutions that can be integrated into the design process. So, the next time you are faced with a misaligned spline coupling problem, make sure to use an analytical approach!
In this study, the spline coupling is analyzed under nominal conditions without a parallel offset misalignment. The stiffness values obtained are the percentage difference between the nominal pitch diameter and load application diameter. Moreover, the maximum percentage difference in the measured pitch diameter is 1.60% under a torque of 5000 N*m. The other parameter, the pitch angle, is taken into consideration in the calculation.

A spline coupler is a device used to connect splined shafts. A typical spline coupler resembles a short pipe with splines on either end. There are 2 basic types of spline coupling: single and dual spline. One type attaches to a drive shaft, while the other attaches to the gearbox. While spline couplings are typically used in racing, they’re also used for performance problems.
The key challenge in spline couplings is to determine the optimal dimension of spline joints. This is difficult because no commercial codes allow the simulation of misaligned joints, which can destroy components. This article presents analytical approaches to estimating contact pressures in spline connections. The results are comparable with numerical approaches but require special codes to accurately model the coupling operation. This research highlights several important issues and aims to make the application of spline couplings in high-performance vehicles easier.
The stiffness of spline assemblies can be calculated using tooth-like structures. Such splines can be incorporated into the spline joint to produce global stiffness for torsional vibration analysis. Bearing reactions are calculated for a certain level of misalignment. This information can be used to design bearing dimensions and correct misalignment. There are 3 types of spline couplings.
Major diameter fit splines are made with tightly controlled outside diameters. This close fit provides concentricity transfer from the male to the female spline. The teeth of the male spline usually have chamfered tips and clearance with fillet radii. These splines are often manufactured from billet steel or aluminum. These materials are renowned for their strength and uniform grain created by the forging process. ANSI and DIN design manuals define classes of fit.

Disc brake mounting interfaces

A spline coupling for disc brake mounting interfaces is a type of hub-to-brake-disc mount. It is a highly durable coupling mechanism that reduces heat transfer from the disc to the axle hub. The mounting arrangement also isolates the axle hub from direct contact with the disc. It is also designed to minimize the amount of vehicle downtime and maintenance required to maintain proper alignment.
Disc brakes typically have substantial metal-to-metal contact with axle hub splines. The discs are held in place on the hub by intermediate inserts. This metal-to-metal contact also aids in the transfer of brake heat from the brake disc to the axle hub. Spline coupling for disc brake mounting interfaces comprises a mounting ring that is either a threaded or non-threaded spline.
During drag brake experiments, perforated friction blocks filled with various additive materials are introduced. The materials included include Cu-based powder metallurgy material, a composite material, and a Mn-Cu damping alloy. The filling material affects the braking interface’s wear behavior and friction-induced vibration characteristics. Different filling materials produce different types of wear debris and have different wear evolutions. They also differ in their surface morphology.
Disc brake couplings are usually made of 2 different types. The plain and HD versions are interchangeable. The plain version is the simplest to install, while the HD version has multiple components. The two-piece couplings are often installed at the same time, but with different mounting interfaces. You should make sure to purchase the appropriate coupling for your vehicle. These interfaces are a vital component of your vehicle and must be installed correctly for proper operation.
Disc brakes use disc-to-hub elements that help locate the forces and displace them to the rim. These elements are typically made of stainless steel, which increases the cost of manufacturing the disc brake mounting interface. Despite their benefits, however, the high braking force loads they endure are hard on the materials. Moreover, excessive heat transferred to the intermediate elements can adversely affect the fatigue life and long-term strength of the brake system.

Analytical Approaches to Estimating Contact Pressures in Spline Couplings

A spline coupling is a type of mechanical connection between 2 rotating shafts. It consists of 2 parts – a coupler and a coupling. Both parts have teeth which engage and transfer loads. However, spline couplings are typically over-dimensioned, which makes them susceptible to fatigue and static behavior. Wear phenomena can also cause the coupling to fail. For this reason, proper spline coupling design is essential for achieving optimum performance.

Modeling a spline coupling

Spline couplings are becoming increasingly popular in the aerospace industry, but they operate in a slightly misaligned state, causing both vibrations and damage to the contact surfaces. To solve this problem, this article offers analytical approaches for estimating the contact pressures in a spline coupling. Specifically, this article compares analytical approaches with pure numerical approaches to demonstrate the benefits of an analytical approach.
To model a spline coupling, first you create the knowledge base for the spline coupling. The knowledge base includes a large number of possible specification values, which are related to each other. If you modify 1 specification, it may lead to a warning for violating another. To make the design valid, you must create a spline coupling model that meets the specified specification values.
After you have modeled the geometry, you must enter the contact pressures of the 2 spline couplings. Then, you need to determine the position of the pitch circle of the spline. In Figure 2, the centre of the male coupling is superposed to that of the female spline. Then, you need to make sure that the alignment meshing distance of the 2 splines is the same.
Once you have the data you need to create a spline coupling model, you can begin by entering the specifications for the interface design. Once you have this data, you need to choose whether to optimize the internal spline or the external spline. You’ll also need to specify the tooth friction coefficient, which is used to determine the stresses in the spline coupling model 20. You should also enter the pilot clearance, which is the clearance between the tip 186 of a tooth 32 on 1 spline and the feature on the mating spline.
After you have entered the desired specifications for the external spline, you can enter the parameters for the internal spline. For example, you can enter the outer diameter limit 154 of the major snap 54 and the minor snap 56 of the internal spline. The values of these parameters are displayed in color-coded boxes on the Spline Inputs and Configuration GUI screen 80. Once the parameters are entered, you’ll be presented with a geometric representation of the spline coupling model 20.

Creating a spline coupling model 20

The spline coupling model 20 is created by a product model software program 10. The software validates the spline coupling model against a knowledge base of configuration-dependent specification constraints and relationships. This report is then input to the ANSYS stress analyzer program. It lists the spline coupling model 20’s geometric configurations and specification values for each feature. The spline coupling model 20 is automatically recreated every time the configuration or performance specifications of the spline coupling model 20 are modified.
The spline coupling model 20 can be configured using the product model software program 10. A user specifies the axial length of the spline stack, which may be zero, or a fixed length. The user also enters a radial mating face 148, if any, and selects a pilot clearance specification value of 14.5 degrees or 30 degrees.
A user can then use the mouse 110 to modify the spline coupling model 20. The spline coupling knowledge base contains a large number of possible specification values and the spline coupling design rule. If the user tries to change a spline coupling model, the model will show a warning about a violation of another specification. In some cases, the modification may invalidate the design.
In the spline coupling model 20, the user enters additional performance requirement specifications. The user chooses the locations where maximum torque is transferred for the internal and external splines 38 and 40. The maximum torque transfer location is determined by the attachment configuration of the hardware to the shafts. Once this is selected, the user can click “Next” to save the model. A preview of the spline coupling model 20 is displayed.
The model 20 is a representation of a spline coupling. The spline specifications are entered in the order and arrangement as specified on the spline coupling model 20 GUI screen. Once the spline coupling specifications are entered, the product model software program 10 will incorporate them into the spline coupling model 20. This is the last step in spline coupling model creation.

Analysing a spline coupling model 20

An analysis of a spline coupling model consists of inputting its configuration and performance specifications. These specifications may be generated from another computer program. The product model software program 10 then uses its internal knowledge base of configuration dependent specification relationships and constraints to create a valid three-dimensional parametric model 20. This model contains information describing the number and types of spline teeth 32, snaps 34, and shoulder 36.
When you are analysing a spline coupling, the software program 10 will include default values for various specifications. The spline coupling model 20 comprises an internal spline 38 and an external spline 40. Each of the splines includes its own set of parameters, such as its depth, width, length, and radii. The external spline 40 will also contain its own set of parameters, such as its orientation.
Upon selecting these parameters, the software program will perform various analyses on the spline coupling model 20. The software program 10 calculates the nominal and maximal tooth bearing stresses and fatigue life of a spline coupling. It will also determine the difference in torsional windup between an internal and an external spline. The output file from the analysis will be a report file containing model configuration and specification data. The output file may also be used by other computer programs for further analysis.
Once these parameters are set, the user enters the design criteria for the spline coupling model 20. In this step, the user specifies the locations of maximum torque transfer for both the external and internal spline 38. The maximum torque transfer location depends on the configuration of the hardware attached to the shafts. The user may enter up to 4 different performance requirement specifications for each spline.
The results of the analysis show that there are 2 phases of spline coupling. The first phase shows a large increase in stress and vibration. The second phase shows a decline in both stress and vibration levels. The third stage shows a constant meshing force between 300N and 320N. This behavior continues for a longer period of time, until the final stage engages with the surface.

Misalignment of a spline coupling

A study aimed to investigate the position of the resultant contact force in a spline coupling engaging teeth under a steady torque and rotating misalignment. The study used numerical methods based on Finite Element Method (FEM) models. It produced numerical results for nominal conditions and parallel offset misalignment. The study considered 2 levels of misalignment – 0.02 mm and 0.08 mm – with different loading levels.
The results showed that the misalignment between the splines and rotors causes a change in the meshing force of the spline-rotor coupling system. Its dynamics is governed by the meshing force of splines. The meshing force of a misaligned spline coupling is related to the rotor-spline coupling system parameters, the transmitting torque, and the dynamic vibration displacement.
Despite the lack of precise measurements, the misalignment of splines is a common problem. This problem is compounded by the fact that splines usually feature backlash. This backlash is the result of the misaligned spline. The authors analyzed several splines, varying pitch diameters, and length/diameter ratios.
A spline coupling is a two-dimensional mechanical system, which has positive backlash. The spline coupling is comprised of a hub and shaft, and has tip-to-root clearances that are larger than the backlash. A form-clearance is sufficient to prevent tip-to-root fillet contact. The torque on the splines is transmitted via friction.
When a spline coupling is misaligned, a torque-biased thrust force is generated. In such a situation, the force can exceed the torque, causing the component to lose its alignment. The two-way transmission of torque and thrust is modeled analytically in the present study. The analytical approach provides solutions that can be integrated into the design process. So, the next time you are faced with a misaligned spline coupling problem, make sure to use an analytical approach!
In this study, the spline coupling is analyzed under nominal conditions without a parallel offset misalignment. The stiffness values obtained are the percentage difference between the nominal pitch diameter and load application diameter. Moreover, the maximum percentage difference in the measured pitch diameter is 1.60% under a torque of 5000 N*m. The other parameter, the pitch angle, is taken into consideration in the calculation.

Product Description

Cylindrical Roller Bearing (N318ECM, NJ312) Description

NJ design 

The outer ring has 2 integral flanges and the inner ring 1 integral flange. The bearings are therefore suitable for the axial location of a shaft in 1 direction. 

 

 

Cylindrical roller bearings are widely used in the bearing of gearbox, CZPT of rear axle bevel gear in a car and all kinds of engineering equipment. Roller and rolling way contact with a streamline that makes radial bearing capacity great. Those whose external and internal rings without a board (type of NU, N) cannot support the axial load, while those with a board (type of NJ, NUP) can support the axial load to a certain extent. 

There is a line contact between cylindrical roller and roller path, while the radcat liad capacity is great, so these products not only apply to heavy load and shock load, but also apply to high-speed rotation. The N and NU types can realize axial movements, which apply to changes of axle and casing relative positions resulting from thermal expansion or installation error.

Applications of Spline Couplings

A spline coupling is a highly effective means of connecting 2 or more components. These types of couplings are very efficient, as they combine linear motion with rotation, and their efficiency makes them a desirable choice in numerous applications. Read on to learn more about the main characteristics and applications of spline couplings. You will also be able to determine the predicted operation and wear. You can easily design your own couplings by following the steps outlined below.

Optimal design

The spline coupling plays an important role in transmitting torque. It consists of a hub and a shaft with splines that are in surface contact without relative motion. Because they are connected, their angular velocity is the same. The splines can be designed with any profile that minimizes friction. Because they are in contact with each other, the load is not evenly distributed, concentrating on a small area, which can deform the hub surface.
Optimal spline coupling design takes into account several factors, including weight, material characteristics, and performance requirements. In the aeronautics industry, weight is an important design factor. S.A.E. and ANSI tables do not account for weight when calculating the performance requirements of spline couplings. Another critical factor is space. Spline couplings may need to fit in tight spaces, or they may be subject to other configuration constraints.
Optimal design of spline couplers may be characterized by an odd number of teeth. However, this is not always the case. If the external spline’s outer diameter exceeds a certain threshold, the optimal spline coupling model may not be an optimal choice for this application. To optimize a spline coupling for a specific application, the user may need to consider the sizing method that is most appropriate for their application.
Once a design is generated, the next step is to test the resulting spline coupling. The system must check for any design constraints and validate that it can be produced using modern manufacturing techniques. The resulting spline coupling model is then exported to an optimisation tool for further analysis. The method enables a designer to easily manipulate the design of a spline coupling and reduce its weight.
The spline coupling model 20 includes the major structural features of a spline coupling. A product model software program 10 stores default values for each of the spline coupling’s specifications. The resulting spline model is then calculated in accordance with the algorithm used in the present invention. The software allows the designer to enter the spline coupling’s radii, thickness, and orientation.

Characteristics

An important aspect of aero-engine splines is the load distribution among the teeth. The researchers have performed experimental tests and have analyzed the effect of lubrication conditions on the coupling behavior. Then, they devised a theoretical model using a Ruiz parameter to simulate the actual working conditions of spline couplings. This model explains the wear damage caused by the spline couplings by considering the influence of friction, misalignment, and other conditions that are relevant to the splines’ performance.
In order to design a spline coupling, the user first inputs the design criteria for sizing load carrying sections, including the external spline 40 of the spline coupling model 30. Then, the user specifies torque margin performance requirement specifications, such as the yield limit, plastic buckling, and creep buckling. The software program then automatically calculates the size and configuration of the load carrying sections and the shaft. These specifications are then entered into the model software program 10 as specification values.
Various spline coupling configuration specifications are input on the GUI screen 80. The software program 10 then generates a spline coupling model by storing default values for the various specifications. The user then can manipulate the spline coupling model by modifying its various specifications. The final result will be a computer-aided design that enables designers to optimize spline couplings based on their performance and design specifications.
The spline coupling model software program continually evaluates the validity of spline coupling models for a particular application. For example, if a user enters a data value signal corresponding to a parameter signal, the software compares the value of the signal entered to the corresponding value in the knowledge base. If the values are outside the specifications, a warning message is displayed. Once this comparison is completed, the spline coupling model software program outputs a report with the results.
Various spline coupling design factors include weight, material properties, and performance requirements. Weight is 1 of the most important design factors, particularly in the aeronautics field. ANSI and S.A.E. tables do not consider these factors when calculating the load characteristics of spline couplings. Other design requirements may also restrict the configuration of a spline coupling.

Applications

Spline couplings are a type of mechanical joint that connects 2 rotating shafts. Its 2 parts engage teeth that transfer load. Although splines are commonly over-dimensioned, they are still prone to fatigue and static behavior. These properties also make them prone to wear and tear. Therefore, proper design and selection are vital to minimize wear and tear on splines. There are many applications of spline couplings.
A key design is based on the size of the shaft being joined. This allows for the proper spacing of the keys. A novel method of hobbing allows for the formation of tapered bases without interference, and the root of the keys is concentric with the axis. These features enable for high production rates. Various applications of spline couplings can be found in various industries. To learn more, read on.
FE based methodology can predict the wear rate of spline couplings by including the evolution of the coefficient of friction. This method can predict fretting wear from simple round-on-flat geometry, and has been calibrated with experimental data. The predicted wear rate is reasonable compared to the experimental data. Friction evolution in spline couplings depends on the spline geometry. It is also crucial to consider the lubrication condition of the splines.
Using a spline coupling reduces backlash and ensures proper alignment of mated components. The shaft’s splined tooth form transfers rotation from the splined shaft to the internal splined member, which may be a gear or other rotary device. A spline coupling’s root strength and torque requirements determine the type of spline coupling that should be used.
The spline root is usually flat and has a crown on 1 side. The crowned spline has a symmetrical crown at the centerline of the face-width of the spline. As the spline length decreases toward the ends, the teeth are becoming thinner. The tooth diameter is measured in pitch. This means that the male spline has a flat root and a crowned spline.

Predictability

Spindle couplings are used in rotating machinery to connect 2 shafts. They are composed of 2 parts with teeth that engage each other and transfer load. Spline couplings are commonly over-dimensioned and are prone to static and fatigue behavior. Wear phenomena are also a common problem with splines. To address these issues, it is essential to understand the behavior and predictability of these couplings.
Dynamic behavior of spline-rotor couplings is often unclear, particularly if the system is not integrated with the rotor. For example, when a misalignment is not present, the main response frequency is 1 X-rotating speed. As the misalignment increases, the system starts to vibrate in complex ways. Furthermore, as the shaft orbits depart from the origin, the magnitudes of all the frequencies increase. Thus, research results are useful in determining proper design and troubleshooting of rotor systems.
The model of misaligned spline couplings can be obtained by analyzing the stress-compression relationships between 2 spline pairs. The meshing force model of splines is a function of the system mass, transmitting torque, and dynamic vibration displacement. This model holds when the dynamic vibration displacement is small. Besides, the CZPT stepping integration method is stable and has high efficiency.
The slip distributions are a function of the state of lubrication, coefficient of friction, and loading cycles. The predicted wear depths are well within the range of measured values. These predictions are based on the slip distributions. The methodology predicts increased wear under lightly lubricated conditions, but not under added lubrication. The lubrication condition and coefficient of friction are the key factors determining the wear behavior of splines.
