摆线针轮行星传动中反弓齿廓研究与分析

Inverse Arch-shaped Teeth Profile and its Optimization in a Cycloid Drive

在对摆线针轮行星传动中摆线轮修形所产生的相对转角进行计算的基础上,提出了反弓齿廓的概念,并给出了反弓齿廓的存在条件,采用"正等距+负移距"简单组合修行方法可以获得反弓齿廓 计算表明:最佳反弓齿廓可以有效地减少最大接触力和接触应力。

The relative angle between pinwheel and cycloid disk is discussed after the equidistant modification and radial-moving modification, the concept of the Inverse Arch-shaped Teeth profile is proposed in order to improve contacting state, reduce contacting force and make full use of the cycloid teeth profile. The formula of the existing condition are given, and the Inverse Arch-shaped teeth profile is obtained easily through ' plus equidistant + minus radial-moving combining modification if the modification meets the given conditions. The calculated results show that the contacting force of the Inverse Arch-shaped Teeth profile is obviously better than the other modification method.
