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.
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.

Stiffness and Torsional Vibration of Spline-Couplings

In this paper, we describe some basic characteristics of spline-coupling and examine its torsional vibration behavior. We also explore the effect of spline misalignment on rotor-spline coupling. These results will assist in the design of improved spline-coupling systems for various applications. The results are presented in Table 1.
splineshaft

Stiffness of spline-coupling

The stiffness of a spline-coupling is a function of the meshing force between the splines in a rotor-spline coupling system and the static vibration displacement. The meshing force depends on the coupling parameters such as the transmitting torque and the spline thickness. It increases nonlinearly with the spline thickness.
A simplified spline-coupling model can be used to evaluate the load distribution of splines under vibration and transient loads. The axle spline sleeve is displaced a z-direction and a resistance moment T is applied to the outer face of the sleeve. This simple model can satisfy a wide range of engineering requirements but may suffer from complex loading conditions. Its asymmetric clearance may affect its engagement behavior and stress distribution patterns.
The results of the simulations show that the maximum vibration acceleration in both Figures 10 and 22 was 3.03 g/s. This results indicate that a misalignment in the circumferential direction increases the instantaneous impact. Asymmetry in the coupling geometry is also found in the meshing. The right-side spline’s teeth mesh tightly while those on the left side are misaligned.
Considering the spline-coupling geometry, a semi-analytical model is used to compute stiffness. This model is a simplified form of a classical spline-coupling model, with submatrices defining the shape and stiffness of the joint. As the design clearance is a known value, the stiffness of a spline-coupling system can be analyzed using the same formula.
The results of the simulations also show that the spline-coupling system can be modeled using MASTA, a high-level commercial CAE tool for transmission analysis. In this case, the spline segments were modeled as a series of spline segments with variable stiffness, which was calculated based on the initial gap between spline teeth. Then, the spline segments were modelled as a series of splines of increasing stiffness, accounting for different manufacturing variations. The resulting analysis of the spline-coupling geometry is compared to those of the finite-element approach.
Despite the high stiffness of a spline-coupling system, the contact status of the contact surfaces often changes. In addition, spline coupling affects the lateral vibration and deformation of the rotor. However, stiffness nonlinearity is not well studied in splined rotors because of the lack of a fully analytical model.
splineshaft

Characteristics of spline-coupling

The study of spline-coupling involves a number of design factors. These include weight, materials, and performance requirements. Weight is particularly important in the aeronautics field. Weight is often an issue for design engineers because materials have varying dimensional stability, weight, and durability. Additionally, space constraints and other configuration restrictions may require the use of spline-couplings in certain applications.
The main parameters to consider for any spline-coupling design are the maximum principal stress, the maldistribution factor, and the maximum tooth-bearing stress. The magnitude of each of these parameters must be smaller than or equal to the external spline diameter, in order to provide stability. The outer diameter of the spline must be at least 4 inches larger than the inner diameter of the spline.
Once the physical design is validated, the spline coupling knowledge base is created. This model is pre-programmed and stores the design parameter signals, including performance and manufacturing constraints. It then compares the parameter values to the design rule signals, and constructs a geometric representation of the spline coupling. A visual model is created from the input signals, and can be manipulated by changing different parameters and specifications.
The stiffness of a spline joint is another important parameter for determining the spline-coupling stiffness. The stiffness distribution of the spline joint affects the rotor’s lateral vibration and deformation. A finite element method is a useful technique for obtaining lateral stiffness of spline joints. This method involves many mesh refinements and requires a high computational cost.
The diameter of the spline-coupling must be large enough to transmit the torque. A spline with a larger diameter may have greater torque-transmitting capacity because it has a smaller circumference. However, the larger diameter of a spline is thinner than the shaft, and the latter may be more suitable if the torque is spread over a greater number of teeth.
Spline-couplings are classified according to their tooth profile along the axial and radial directions. The radial and axial tooth profiles affect the component’s behavior and wear damage. Splines with a crowned tooth profile are prone to angular misalignment. Typically, these spline-couplings are oversized to ensure durability and safety.

Stiffness of spline-coupling in torsional vibration analysis

This article presents a general framework for the study of torsional vibration caused by the stiffness of spline-couplings in aero-engines. It is based on a previous study on spline-couplings. It is characterized by the following 3 factors: bending stiffness, total flexibility, and tangential stiffness. The first criterion is the equivalent diameter of external and internal splines. Both the spline-coupling stiffness and the displacement of splines are evaluated by using the derivative of the total flexibility.
The stiffness of a spline joint can vary based on the distribution of load along the spline. Variables affecting the stiffness of spline joints include the torque level, tooth indexing errors, and misalignment. To explore the effects of these variables, an analytical formula is developed. The method is applicable for various kinds of spline joints, such as splines with multiple components.
Despite the difficulty of calculating spline-coupling stiffness, it is possible to model the contact between the teeth of the shaft and the hub using an analytical approach. This approach helps in determining key magnitudes of coupling operation such as contact peak pressures, reaction moments, and angular momentum. This approach allows for accurate results for spline-couplings and is suitable for both torsional vibration and structural vibration analysis.
The stiffness of spline-coupling is commonly assumed to be rigid in dynamic models. However, various dynamic phenomena associated with spline joints must be captured in high-fidelity drivetrain models. To accomplish this, a general analytical stiffness formulation is proposed based on a semi-analytical spline load distribution model. The resulting stiffness matrix contains radial and tilting stiffness values as well as torsional stiffness. The analysis is further simplified with the blockwise inversion method.
It is essential to consider the torsional vibration of a power transmission system before selecting the coupling. An accurate analysis of torsional vibration is crucial for coupling safety. This article also discusses case studies of spline shaft wear and torsionally-induced failures. The discussion will conclude with the development of a robust and efficient method to simulate these problems in real-life scenarios.

Effect of spline misalignment on rotor-spline coupling

In this study, the effect of spline misalignment in rotor-spline coupling is investigated. The stability boundary and mechanism of rotor instability are analyzed. We find that the meshing force of a misaligned spline coupling increases nonlinearly with spline thickness. The results demonstrate that the misalignment is responsible for the instability of the rotor-spline coupling system.
An intentional spline misalignment is introduced to achieve an interference fit and zero backlash condition. This leads to uneven load distribution among the spline teeth. A further spline misalignment of 50um can result in rotor-spline coupling failure. The maximum tensile root stress shifted to the left under this condition.
Positive spline misalignment increases the gear mesh misalignment. Conversely, negative spline misalignment has no effect. The right-handed spline misalignment is opposite to the helix hand. The high contact area is moved from the center to the left side. In both cases, gear mesh is misaligned due to deflection and tilting of the gear under load.
This variation of the tooth surface is measured as the change in clearance in the transverse plain. The radial and axial clearance values are the same, while the difference between the 2 is less. In addition to the frictional force, the axial clearance of the splines is the same, which increases the gear mesh misalignment. Hence, the same procedure can be used to determine the frictional force of a rotor-spline coupling.
Gear mesh misalignment influences spline-rotor coupling performance. This misalignment changes the distribution of the gear mesh and alters contact and bending stresses. Therefore, it is essential to understand the effects of misalignment in spline couplings. Using a simplified system of helical gear pair, Hong et al. examined the load distribution along the tooth interface of the spline. This misalignment caused the flank contact pattern to change. The misaligned teeth exhibited deflection under load and developed a tilting moment on the gear.
The effect of spline misalignment in rotor-spline couplings is minimized by using a mechanism that reduces backlash. The mechanism comprises cooperably splined male and female members. One member is formed by 2 coaxially aligned splined segments with end surfaces shaped to engage in sliding relationship. The connecting device applies axial loads to these segments, causing them to rotate relative to 1 another.

The Functions of Splined Shaft Bearings

Splined shafts are the most common types of bearings for machine tools. They are made of a wide variety of materials, including metals and non-metals such as Delrin and nylon. They are often fabricated to reduce deflection. The tooth profile will become deformed with time, as the shaft is used over a long period of time. Splined shafts are available in a huge range of materials and lengths.

Functions

Splined shafts are used in a variety of applications and industries. They are an effective anti-rotational device, as well as a reliable means of transmitting torque. Other types of shafts are available, including key shafts, but splines are the most convenient for transmitting torque. The following article discusses the functions of splines and why they are a superior choice. Listed below are a few examples of applications and industries in which splines are used.
Splined shafts can be of several styles, depending on the application and mechanical system in question. The differences between splined shaft styles include the design of teeth, overall strength, transfer of rotational concentricity, sliding ability, and misalignment tolerance. Listed below are a few examples of splines, as well as some of their benefits. The difference between these styles is not mutually exclusive; instead, each style has a distinct set of pros and cons.
A splined shaft is a cylindrical shaft with teeth or ridges that correspond to a specific angular position. This allows a shaft to transfer torque while maintaining angular correspondence between tracks. A splined shaft is defined as a cylindrical member with several grooves cut into its circumference. These grooves are equally spaced around the shaft and form a series of projecting keys. These features give the shaft a rounded appearance and allow it to fit perfectly into a grooved cylindrical member.
While the most common applications of splines are for shortening or extending shafts, they can also be used to secure mechanical assemblies. An “involute spline” spline has a groove that is wider than its counterparts. The result is that a splined shaft will resist separation during operation. They are an ideal choice for applications where deflection is an issue.
A spline shaft’s radial torsion load distribution is equally distributed, unless a bevel gear is used. The radial torsion load is evenly distributed and will not exert significant load concentration. If the spline couplings are not aligned correctly, the spline connection can fail quickly, causing significant fretting fatigue and wear. A couple of papers discuss this issue in more detail.
splineshaft

Types

There are many different types of splined shafts. Each type features an evenly spaced helix of grooves on its outer surface. These grooves are either parallel or involute. Their shape allows them to be paired with gears and interchange rotary and linear motion. Splines are often cold-rolled or cut. The latter has increased strength compared to cut spines. These types of shafts are commonly used in applications requiring high strength, accuracy, and smoothness.
Another difference between internal and external splined shafts lies in the manufacturing process. The former is made of wood, while the latter is made of steel or a metal alloy. The process of manufacturing splined shafts involves cutting furrows into the surface of the material. Both processes are expensive and require expert skill. The main advantage of splined shafts is their adaptability to a wide range of applications.
In general, splined shafts are used in machinery where the rotation is transferred to an internal splined member. This member can be a gear or some other rotary device. These types of shafts are often packaged together as a hub assembly. Cleaning and lubricating are essential to the life of these components. If you’re using them on a daily basis, you’ll want to make sure to regularly inspect them.
Crowned splines are usually involute. The teeth of these splines form a spiral pattern. They are used for smaller diameter shafts because they add strength. Involute splines are also used on instrument drives and valve shafts. Serration standards are found in the SAE. Both kinds of splines can also contain a ball bearing for high torque. The difference between the 2 types of splines is the number of teeth on the shaft.
Internal splines have many advantages over external ones. For example, an internal spline shaft can be made using a grinding wheel instead of a CNC machine. It also uses a more accurate and economical process. Furthermore, it allows for a shorter manufacturing cycle, which is essential when splining high-speed machines. In addition, it stabilizes the relative phase between the spline and thread.
splineshaft

Manufacturing methods

There are several methods used to fabricate a splined shaft. Key and splined shafts are constructed from 2 separate parts that are shaped in a synchronized manner to transfer torque uniformly. Hot rolling is 1 method, while cold rolling utilizes low temperatures to form metal. Both methods enhance mechanical properties, surface finishes, and precision. The advantage of cold rolling is its cost-effectiveness.
Cold forming is 1 method, as well as machining and assembling. Cold forming is a unique process that allows the spline to be shaped to the desired shape. The resulting shape provides maximum contact area and torsional strength. Standard splines are available in standard sizes, but custom lengths can also be ordered. CZPT offers various auxiliary equipment, such as mating sleeves and flanged bushings.
Cold forging is another method. This method produces long splined shafts that are used in automobile propellers. After the spline portion is cut out, it is worked on in a hobbing machine. Work hardening enhances the root strength of the splined portion. It can be used for bearings, gears, and other mechanical components. Listed below are the manufacturing methods for splined shafts.
Parallel splines are the simplest of the splined shaft manufacturing methods. Parallel splines are usually welded to shafts, while involute splines are made of metal or non-metals. Splines are available in a wide variety of lengths and materials. The process is usually accompanied by a process called milling. The workpiece rotates to produce the serrated surface.
Splines are internal or external grooves in a splined shaft. They work in combination with keyways to transfer torque. Male and female splines are used in gears. Female and male splines correspond to 1 another to ensure proper angular correspondence. Involute splines have more surface area and thus are stronger than external splines. Moreover, they help the shaft fit into a grooved cylindrical member without misalignment.
A variety of other methods of manufacturing a splined shaft can be used to produce a splined shaft. Spline shafts can be produced using broaching and shaping, 2 precision machining methods. Broaching uses a metal tool with successively larger teeth to remove metal and create ridges and holes in the surface of a material. However, this process is expensive and requires special expertise.
splineshaft

Applications

The splined shaft is a mechanical component with a helix-like shape formed by the equal spacing of grooves in a circular ring. The splines can either have parallel or involute sides. The splines minimize stress concentration in stationary joints and can be used in both rotary and linear motion. In some cases, splines are rolled rather than cut. The latter is more durable than cut splines and is often used in applications requiring high strength, accuracy, and smooth finish.
Splined shafts are commonly made of carbon steel. This alloy steel has a low carbon content, making it easy to work with. Carbon steel is a great choice for splines because it is malleable. Generally, high-quality carbon steel provides a consistent motion. Steel alloys are also available that contain nickel, chromium, copper, and other metals. If you’re unsure of the right material for your application, you can consult a spline chart.
Splines are a versatile mechanical component. They are easy to cut and fit. Splines can be internal or external, with teeth positioned at equal intervals on both sides of the shaft. This allows the shaft to engage with the hub around the entire circumference of the hub. It also increases load capacity by creating a constant multiple-tooth point of contact with the hub. For this reason, they’re used extensively in rotary and linear motion.
Splined shafts are used in a wide variety of industries. CZPT Inc. offers custom and standard splined shafts for a variety of applications. When choosing a splined shaft for a specific application, consider the surrounding mated components, torque requirements, and size requirements.

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.
