[0002] Involute spline connection is an important connection form for mechanical transmission. Because its tooth shape is an involute, there is radial force on the tooth when it is loaded, which can play a role of automatic centering, which is conducive to uniform force on each tooth, high strength and long life. However, in actual application, it is found that the involute spline connection has the problem of uneven load distribution, which causes wear on the tooth surface. In order to solve this problem, it is considered to modify the spline so that the load is distributed in the center of the tooth surface. At present, the method of spline modification design mostly uses finite element analysis or analytical method for calculation.

[0003] However, the modeling process of the finite element analysis method is more complicated, and each time the model is modified, it needs to be re-modeled, which takes a long time; the analytical method uses knowledge of mechanics and mathematics to design from a theoretical perspective, but it also requires simulation or experiments for verification, which is inefficient.

[0050] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0051] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0052] First, some terms involved in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0053] KISSsoft is a professional gear design and analysis software designed to organize, optimize, calculate and re-analyze machine components such as gears, bearings, screws, belts, and detachable cables.

[0054] Romax software is an engineering software that provides design and simulation solutions. It is widely used in various types of product design and has achieved remarkable results.

[0055] This application is applied to the scenario of involute spline design. The specific scenario is to model the reducer system based on Romax software, add a spline modification scheme, perform simulation analysis and output the stress of each spline tooth, perform strength verification while performing the modification design, select the best design scheme, and improve design efficiency.

[0056] Involute spline connection is an important connection form of mechanical transmission. Because its tooth shape is an involute, there is radial force on the teeth when loaded, which can play a role of automatic centering, which is conducive to uniform force on each tooth, high strength and long life. However, in actual application, it is found that the involute spline connection has the problem of uneven load distribution, which causes wear on the tooth surface. In order to solve this problem, it is considered to modify the spline so that the load is distributed in the center of the tooth surface. At present, the methods of spline modification design mostly use finite element analysis or analytical method for calculation. However, the modeling process of the finite element analysis method is more complicated, and each time the model is modified, it needs to be re-modeled, which takes a long time; the analytical method uses mechanics and mathematical knowledge to design from a theoretical perspective, but it also needs simulation or experiment for verification, which is inefficient.

[0057] To this end, the present application uses relevant design software to model the reducer system according to the received spline parameters to obtain the reducer model; add power input and output nodes on the input shaft and output shaft of the reducer model, and set the reducer model load spectrum; run the reducer model according to the reducer model load spectrum, and output the stress distribution data of each tooth surface of the reducer model; according to the modification amount input by the user and the stress distribution data of each tooth surface, select the target modification method to perform involute spline modification, and obtain the involute spline design result, wherein the target modification method includes: at least one of tooth direction drum shape, tooth shape drum shape and helix angle modification. The process of designing the involute spline is simulated by using relevant software to perform model modeling, and after adding different involute spline modifications to the model, the stress of each tooth surface is checked, so that the final involute spline design scheme can be screened, which can achieve the effect of improving the efficiency of the involute spline design process.

[0058] In the embodiment of the present application, the executor may be a designed involute spline device in a designed involute spline system. In actual applications, the designed involute spline device may be an electronic device such as a terminal device and a server, and no limitation is made here.

[0059] Combine the following Figure 1 The method for designing an involute spline in an embodiment of the present application is described in detail.

[0060] Please see Figure 1 , Figure 1 A flow chart of a method for designing an involute spline provided in an embodiment of the present application, such as Figure 1 The method shown for designing an involute spline includes:

[0061] Step 110: Use relevant design software to model the reducer system according to the received spline parameters to obtain a reducer model.

[0062] Among them, the involute spline can be the spline on the motor vehicle reducer. The spline parameters include: module, number of teeth, pressure angle, pitch circle diameter, base circle diameter and pitch, etc. The specific parameters can be reported in terms of major diameter, minor diameter, involute end circle diameter, involute start circle diameter, tolerance grade and fit category, etc.

[0063] In some embodiments of the present application, the relevant software includes: gear design and analysis software and design simulation engineering software.

[0064] In the above process, the reducer can be accurately modeled and simulated through the relevant software.

[0065] Specifically, the gear design and analysis software and the design simulation engineering software can be Kissoft software and Romax software. When the reducer is modeled through the relevant software, each part can be meshed by comparing the finite element analysis, and a 2D model of each component can be generated. After splicing through translation and rotation, the final 3D reducer model can be generated.

[0066] In some embodiments of the present application, the reducer system is modeled using relevant design software according to the received spline parameters to obtain a reducer model, including: creating an empty gearbox assembly through relevant software; adding a reducer bearing component to the empty gearbox assembly, and adjusting each bearing component according to the set extraction position; adding gears, bearings and involute splines to the reducer bearing component; performing gear modeling, bearing modeling and involute spline modeling according to the received gear parameters, bearing parameters and involute splines, respectively, to obtain a reducer model.

[0067] In the above process, the present application models various hardware according to the parameters corresponding to different hardware, and various hardware models can be added to the empty gearbox assembly to achieve rapid modeling of the reducer.

[0068] The empty gearbox assembly includes a box and grooves for placing gears and shafts. When creating an empty gearbox assembly, you can select the checkbox to automatically generate it according to the parameters of the assembly (for example, the number and specifications of gears and shafts). The gearbox assembly is the core of the reducer model, and all components must be in this assembly to be considered as the part to be analyzed.

[0069] Optionally, when adding a reducer bearing component, you can create a new shaft assembly with preset dimensions, and then edit the inner radius and length of each shaft to create intermediate and output shafts, etc. The axes can be set using both absolute and relative coordinate systems. For example, the input axis is set in absolute coordinate system, and the remaining axes are set relative to the input axis.

[0070] Optionally, gears, bearings and involute splines are added to the reducer bearing component; gear modeling, bearing modeling and involute spline modeling are performed respectively according to the received gear parameters, bearing parameters and involute splines to obtain the reducer model explosion, including editing gears, bearings and involute splines according to preset size, number of teeth and model through a 2D editing interface, and connecting various parts by dragging and dropping to realize reducer modeling. The preset size, number of teeth and model can be set according to requirements.

[0071] Step 120: Add power input and output nodes on the input shaft and output shaft of the reducer model, and set the load spectrum of the reducer model.

[0072] Among them, the load spectrum of the reducer model can be set by creating a new load spectrum, selecting the input shaft as the input, setting the input torque and speed, and setting it according to the load spectrum of the actual vehicle converted to the load of the reducer. It can also be set by dividing the maximum load into different percentages between the maximum load and the reverse maximum load to obtain the load spectrum.

[0073] In some embodiments of the present application, power input and output nodes are added to the input shaft and output shaft of the reducer model, and the reducer model load spectrum is set, including: debugging the orientation of the housing and bearings of the reducer model so that the housing and bearings of the reducer model coincide with each other to obtain the debugged reducer model; adding power input and output nodes to the input shaft and output shaft of the debugged reducer model, and setting the reducer model load spectrum according to the load amount of the reducer model after the debugged model converted from the vehicle load spectrum.

[0074] In the above process, the housing and bearing of the reducer model can be connected together through debugging to achieve the simulation effect. At the same time, the load spectrum of the reducer model can be designed according to the load of the reducer model in the whole vehicle, so as to provide simulation conditions for the subsequent involute spline design.

[0075] Among them, in addition to setting the reducer model load spectrum according to the load amount of the reducer model after debugging converted from the vehicle load spectrum, the reducer model load spectrum can also be set by dividing the maximum load into different percentages between the maximum load and the anti-drag maximum load.

[0076] In some embodiments of the present application, the orientation of the housing and the bearing of the reducer model is debugged so that the housing and the bearing of the reducer model overlap to obtain the debugged reducer model, including: importing a mesh shell finite element model of the reducer model; rotating and translating the reducer model on the mesh of the mesh shell finite element model so that the housing and the bearing of the reducer model overlap to obtain the debugged reducer model.

[0077] In the above process, the present application can design the shell and the shaft in the grid, and finally realize the conversion from two-dimensional to three-dimensional model through rotation and translation, so as to realize the modeling of the reducer model.

[0078] Among them, the housing and bearings of the reducer model can be modeled on a 2D grid, and 3D reducer modeling can be achieved through translation and rotation.

[0079] Step 130: Run the reducer model according to the reducer model load spectrum, and output stress distribution data of each tooth surface of the reducer model.

[0080] The tooth surface stress distribution data include tooth surface stress distribution diagrams, and each tooth surface stress distribution diagram includes different tooth surfaces and corresponding stress values.

[0081] In some embodiments of the present application, the reducer model is run according to the reducer model load spectrum, and the stress distribution data of each tooth surface of the reducer model is output, including: simulating and calculating the unmodified involute spline through the reducer model load spectrum to obtain the stress distribution data of each tooth surface, and drawing the stress distribution diagram of each tooth surface.

[0082] In the above process, the present application realizes the simulation calculation of the involute spline by running the reducer model, and can accurately obtain the stress distribution data of each tooth surface, providing conditions for subsequent shaping solutions.

[0083] Among them, during the simulation calculation, the load data set on the reducer model load spectrum can be input on the input shaft of the reducer model to realize the operation of the reducer model, and the stress distribution data of each tooth surface can be obtained by collecting the stress conditions of each tooth surface during the operation.

[0084] Step 140: According to the modification amount input by the user and the stress distribution data of each tooth surface, a target modification method is selected to perform involute spline modification, and an involute spline design result is obtained.

[0085] The target modification method includes: at least one of tooth direction drumming, tooth profile drumming and helical angle modification, and multiple of tooth direction drumming, tooth profile drumming and helical angle modification can also be superimposed to obtain the corresponding modification method. When performing involute spline modification, the spline modification condition can select the common torque.

[0086] In some embodiments of the present application, based on the shaping amount input by the user and the stress distribution data of each tooth surface, a target shaping method is selected to perform involute spline shaping to obtain an involute spline design result, including: shaping the involute spline by one or more superimposed shaping methods of tooth direction drum shaping, tooth shape drum shaping and helix angle shaping, to obtain current stress distribution data of each tooth surface corresponding to different shaping methods; comparing the current stress distribution data of each tooth surface corresponding to different shaping methods with the stress distribution data of each tooth surface to determine the target shaping method and the involute spline design result.

[0087] In the above process, the present application can adopt one or more superimposed schemes of tooth direction drumming, tooth shape drumming and helix angle modification to perform modification simulation, and finally select the best modification design scheme according to the output stress distribution data of each tooth surface.

[0088] For example, by comparing the spline stress distribution results after simulation, it is found that the tooth drum and helix angle modification are effective in improving the spline stress distribution and reducing the maximum stress on the spline, while the tooth drum increases the maximum stress of the spline. Therefore, the current tooth drum or helix angle modification method can be selected for the design of involute splines, or the current tooth drum and helix angle modification method can be used to design involute splines.

[0089] Optional, Figure 1 The method shown can achieve rapid simulation through preset configuration files and programs. For example, gearbox assemblies, shafts, involute splines and gears of different specifications are respectively formed into corresponding configuration files and configuration programs. When the user clicks on the page to generate gearbox assemblies, shafts, involute splines and gears of corresponding specifications, the system can automatically generate them according to the corresponding configuration files and configuration programs. The user only needs to drag and drop to translate or rotate the parts to achieve reducer modeling and simulation.

[0090] In the above Figure 1 In the process shown, the present application uses relevant design software to model the reducer system according to the received spline parameters to obtain the reducer model; add power input and output nodes on the input shaft and output shaft of the reducer model, and set the reducer model load spectrum; run the reducer model according to the reducer model load spectrum, and output the stress distribution data of each tooth surface of the reducer model; according to the modification amount input by the user and the stress distribution data of each tooth surface, select the target modification method to perform involute spline modification, and obtain the involute spline design result, wherein the target modification method includes: at least one of tooth direction drumming, tooth shape drumming and helix angle modification. The process of designing the involute spline is simulated by using relevant software to perform model modeling, and after adding different involute spline modifications to the model, the stress of each tooth surface is checked, so that the final involute spline design scheme can be screened, and the efficiency of the involute spline design process can be improved.

[0091] Combine the following Figure 2 The implementation method of designing the involute spline in the embodiment of the present application is described in detail.

[0092] Please see Figure 2 , Figure 2 A flowchart of an implementation method for designing an involute spline provided in an embodiment of the present application, such as Figure 2 The implementation method shown for designing an involute spline includes:

[0093] Step 210: Design spline parameters based on Kissoft software.

[0094] Specifically: The spline precision grade and fit type and other parameters are designed by Kissoft software, wherein the fit type includes tooth side fit and tooth top fit, etc.

[0095] Step 220: Model the reducer shaft-tooth system in Romax software.

[0096] Specifically: Romax software is used to model the reducer system according to the received spline parameters to obtain a reducer model.

[0097] Step 230: Import the shell finite element mesh model.

[0098] Specifically: By comparing the finite element analysis, each part is meshed, and a 2D model of each component is generated, and the final 3D reducer model is generated after splicing through translation and rotation.

[0099] Step 240: Import the load spectrum.

[0100] Specifically: the load of the reducer is set according to the actual vehicle load spectrum converted, or the maximum load is set by dividing it into different percentages between the maximum load and the maximum load of reverse drag, and the load spectrum is imported into the reducer model.

[0101] Step 250: Unmodified spline simulation.

[0102] Specifically: directly run the reducer through the load spectrum and detect the first stress data of each tooth surface.

[0103] Step 260: Modification of involute spline.

[0104] Specifically: the involute spline is modified by one or more superimposed modification methods of tooth direction crowning, tooth profile crowning and helix angle modification.

[0105] Step 270: Shaping simulation.

[0106] Specifically: the modified reducer model is simulated according to the load spectrum input, and the second stress data of each tooth surface is detected.

[0107] Step 280: Generate a design solution.

[0108] Specifically: According to the comparison of the first stress data of each tooth surface and the second stress data of the tooth surface, the final modification method is selected and the final involute spline design scheme is generated.
