摘要

以某型号RV减速器作为整机扭转刚度的研究对象,建立了包含摆线轮和行星轮轮齿的啮合刚度、各弹性构件以及曲柄轴承刚度的整机有限元模型。在对摆线轮进行等距和移距综合修形的基础上,对受力变形的RV减速器整机扭转刚度进行了分析计算,同时与通过扭转刚度实验所得到的实验数据进行了对比,最大扭转刚度为278.8 N·m/（’）,最小扭转刚度为247.1 N·m/（’）,但平均刚度数值偏大10.85%,回差偏小8.9%,说明利用有限元对扭转刚度和回差进行仿真分析是可以参考借鉴的。

Abstract

As the research object,the finite element model of a certain type of RV reducer is established in a finite software,considering the meshing stiffness of planetary gears and cycloid gears,elasticity of components and the bearing stiffness. Based on the isometric and shift modification to the cycloid gears,the torsional stiffness of the RV reducer with deformation caused by the meshing force is calculated. At the same time,compare with the data obtained from experiments of torsional stiffness,it is concluded that the maximum torsional stiffness is 278. 8 N·m/（ ’）,and the minimum torsional stiffness is 247. 1 N·m/（ ’）,but the average value of torsional stiffness is larger than the experimental value by 10. 85%,the hysteresis is smaller than that by8. 9%. It shows that the finite element method is can be used for reference to simulate and analyze the torsional stiffness and the hysteresis.
