实现双波四齿差谐波齿轮传动的参数分析

Parameter Analyses of Two-wave and Four-tooth-difference Harmonic Drives

一般谐波齿轮传动的速比最小不宜小于60～80。本文提出采用双波四齿差传动方式,并采用图解法分析和确定了实现其啮合的主要术技参数,在一定条件下可使谐波齿轮传动的最小速比扩宽到30～40。

The speed ratio of ordinary harmonic drives can not be less than 60～80. The writers of this paper advance the type of two-wave and four-tooth-difference drvies, analyse and determine the main technical parameters to accomplish the gearing by means of drawing method, and make the speedratio of harmonic drives expanded to 30～40 in some conditions.
