differential planetary gear train

基本解释

This paper discusses an industrial robot wrist consisting of double-arm planar differential planetary gear train.
本文提出了由双重系杆平面差动轮系机构组成的工业机器人柔性手腕。
In essence the belt planetary gear continuously variable transmission is a planetary differential train the speed of which is adjustable.
带式行星齿轮无级变速器实质上是一种可无级变速的封闭式差动轮系。
About the problem how to calculate efficiency of differential gear train, in this paper, there is a new idea of"extending a differential gear train to an equivalent closed planetary gear train".
本文就如何计算差动轮系效率的问题，提出将差动轮系扩展成为等效封闭式行星轮系再进行计算的思想。
