差动轮系效率计算的简便方法及其应用

The Brief Method on Efficiency Calculation of Differential Gear Train and Its Application

本文应用差动比三角结构图，根据差动轮系和封闭式行星轮系的功率流向及由运动合成与分解可确定的总输入、输出功率，直接列出效率计算关系式。整个过程直观明了，方法简便实用。

This paper introduces a concise method,with which one can write out efficiency calculating formula of differential gear train directly, through applying triangular structural diagram of differential ratio,according to the power-flow direction of differential and enclosing planet gear train and the to-tal input and output power determinated by the motion synthesis and dissolution,The proeess is visible and evident, and the method is brief and convenievt in application.
