摘要

摆线轮是RV减速器中的核心部件，摆线轮的孔型结构对RV减速器的传动平稳度有较大影响。针对摆线针轮传动系统进行啮合接触分析，得到摆线轮在实际啮合过程的实际啮合齿对数，计算出各齿对啮合转角及综合啮合刚度。在有限元软件中，以摆线针轮综合啮合刚度为弹性约束，对摆线轮进行了动态响应分析，摆线轮在扇形减重孔处振动最大，易发生变形。针对摆线轮不同扇形孔结构，采用三因素四水平的正交试验进行了动力学仿真，结果表明，随着摆线轮转速提升，扇形孔的上底圆半径始终是影响摆线轮振动的最主要因素，而倒圆半径的影响力逐渐增强，两腰夹角的影响力逐渐减弱，为摆线轮的结构设计提供了依据。

Abstract

The cycloid gear is the key component of the RV reducer, and the hole structure of the cycloid gear has a great influence on the transmission stability of the of the RV reducer. Based on the meshing contact analysis between the cycloid gear and pin of transmission system, the number of actual meshing teeth pairs of the cycloid gear were obtained. The meshing angle of each tooth pair and the comprehensive meshing stiffness were calculated. Taking the comprehensive meshing stiffness as elastic constraint condition in finite element software, the dynamics harmonic resonance analysis of cycloid gear was carried out. The position of maximum vibration and deformation is located at the fan-shaped lightening hole of cycloid gear plate. According to the different shape of fan-shaped holes of cycloid gear, the dynamics simulation was carried out by orthogonal test with three factors and four levels. The results show that the radius of the top and bottom circle of the fan-shaped hole is always the key factor to the vibration of the cycloidal wheel with the increase of rotation speed, while the vibration increases gradually for the radius of the inverted circle, and decreases for the angle between the waist and the waist. The conclusions are helpful for the structure design of cycloid gear wheel.
