摘要

通过行星传动机构实例计算，分析了行星差动机构与行星封闭差动机构的区别；分析了RV减速器由一齿差摆线针轮减速器的演化过程，提出了一齿差内啮合传动中曲柄轴为负1齿太阳轮的概念并进行传动比等效计算；等效出RV减速器的功率流简图，得出各支路传动功率分配比公式，揭示了RV减速器的行星封闭差动运动实质。对RV减速器的正向设计具有指导意义。

Abstract

The difference between the planetary differential mechanism and the planetary closed differential mechanism is analyzed by examples of planetary transmission mechanism. The evolution process of RV reducer from one tooth differential cycloid needle wheel reducer is analyzed，the concept that the crank shaft is a negative 1 tooth sun wheel in a tooth differential meshing drive is proposed and the transmission ratio equivalent calculation is carried out. The power flow diagram of RV reducer is equivalent，and the transmission power distribution ratio formula of each branch is obtained，and the essence of planetary closed differential motion of RV reducer is revealed. This theoretical analysis is instructive for the forward design of the RV reducer.
