摘要

在分析大速比复合少齿差齿轮传动装置的传动原理和结构特点的基础上，从系统角度出发，考虑该传动装置的三级传动系统耦合变形、摆线轮、输出盘、行星架及各级箱体的具体结构，建立了大速比复合少齿差齿轮传动整机有限元啮合特性分析模型。对该传动装置中的摆线针齿啮合特性、各关键零部件受力和整机传动误差进行仿真分析，讨论了摆线针轮多齿啮合的动态过程。结果表明，减速器运转过程中，各零部件应力波动幅度较小，且均远低于其材料屈服极限；两片摆线轮总是一刚一柔同时承载，刚性区轮齿为主要承载区，柔性区轮齿受力较小，两片摆线轮啮合轮齿数量总和在9~11之间波动；传动误差曲线平稳，呈现周期性，无明显长波，整机传动误差峰峰值为46.719 5″。该研究结果为大速比复合少齿差传动装置的动态特性和啮合特性参数优化设计提供了理论依据。

Abstract

This study analyzes the transmission principle and structural characteristics of a high-speed-ratio compound gear with small tooth difference. On this basis

the finite element meshing characteristic analysis model of the above gear transmission device is established. The model considers the coupling deformation of 3-stage transmission

the specific structure of the cycloid gear

the output disc

the planet carrier and the case. The stress of each key component and the transmission error of the whole machine are simulated and analyzed

and the dynamic process of the multi-tooth meshing of the pin-cycloid transmission is discussed in detail. The results show that during the operation of the reducer

the stress fluctuation range of each component is small

and they are all far below the yield limit of their materials. The two cycloidal gears always bear the load through a rigid zone and a flexible zone simultaneously. The teeth of the rigid zone are the main bearing zone

and the teeth of the flexible zone are less stressed. The total number of meshing gear teeth of the two cycloidal gears is 9-11. The transmission error curve is stable and periodic

without noticeable long waves

and the peak-to-peak value of the transmission error of the whole machine is 46.719 5″. This research provides a theoretical basis for the optimal design of dynamic characteristics and meshing characteristics of the high-speed-ratio compound gear with small tooth difference.
