JD型系列调度绞车的效率计算

Calculation of the efficiency of JD series dispatch winch

通过对ＪＤ型系列调度绞车主传动系统运动学和动力学分析，依据总的传动比及各内传动比的分配，提出了效率的计算公式，该方法简单易算，可供其它封闭差动行星齿轮传动装置在计算效率时参考。

By means of analysis of the JD series dispatch winch master transmission system's locomotion and motivity in the paper, the author advances a new calculation formula for efficiency on basis of allocation of master transmission ratio. The method is simpler than before, and it is helpful for other close differential planet gears when they are calculating the efficiency.
