一.前言目前生产的摆线针齿行星减速机,系一齿差行星傅动机构,其速比范围为11～87。对速比要求再大的可采取多级组合的减速机。但对要求速比小的,则因齿面胶合失效而不能解决,既使速比为11的减速机,也因齿面胶合而不过关。二齿差摆线针齿行星傅动基本上解决了小速比减速机的齿面胶合问题,并且速比可降至6甚至更小。为小速比摆线齿行星傅动开创了一个前途。
I. Preface At present, the cycloid pinion planetary reducer, which is a toothed differential planetary mechanism, has a gear ratio range of 11 ~ 87. Demands on the speed ratio can be large multi-stage combination of reducer. However, when the speed ratio is small, the tooth surface can not be solved due to the glue failure. Even if the gear ratio is 11, the gear surface is not glued to pass the clearance. Bicondendum pinion planetary gear drive basically solves the problem of small gear ratio gluing, and the speed ratio can be reduced to 6 or even smaller. For the small speed cycloid teeth planet Fu opened up a promising future.
