摘要

为提高某齿轮产品的综合动态啮合性能，提出了控制齿面拓扑修形多项式系数的设计方法。利用差齿面，通过承载接触分析及弹流润滑模型，计算了齿面传动误差和啮合功率损失。以承载传动误差幅值、啮合效率及波动量为目标，通过正交试验设计和多因素多水平仿真，获得了齿面最佳拓扑修形参数；分析了修形参数对啮合性能的影响规律。结果表明，齿廓与螺旋线修形密切相关，齿廓修形比例增加，接触路径倾角变大，载荷向齿面中部集中，齿面重合度、接触线差曲率变大，有利于减小齿面接触应力，缓解边缘接触，同时减低齿面摩擦损失。

Abstract

To improve the comprehensive dynamic meshing performance of a certain gear product， a design method for controlling the polynomial coefficients of the topological modification of the tooth surface is proposed. By using Ease-off surface， through the loaded tooth contact analysis and elastohydrodynamic lubrication model， the gear transmission error and meshing power loss are calculated. Taking the loaded transmission error amplitude， meshing efficiency and its fluctuation as the goals， through orthogonal test design and multi-factors and multi-levels simulation， the best topological modification parameters of the tooth surface are obtained. The influence of modification parameters on meshing performance is analyzed. The results show that the tooth profile is closely related to the spiral profile modification， with the increase of the tooth profile modification ratio， the contact path inclination becomes larger， the load is concentrated in the middle of the tooth surface， the contact ratio of tooth surface and the curvature of contact line difference become larger， which is beneficial to reduce the contact stress of tooth surface， alleviate the edge contact， and reduce the tooth surface friction loss at the same time.
