行星轮系传动比的计算方法有相对速度法、力矩分析法、速度图解法和向量图解法等。其中最常用的是相对速度法。我们在成都东站货场开门办学时采用了图加法进行教学,工农兵学员认为比较直观易懂,特简要地介绍供同志们参考。行星轮系的行星轮随着动轴作公转,又绕动轴作自转,其中心轮的转速可视为由行星轮的公转与自转复合而成的。本文介绍的图加法是把行星轮系分解为行星轮只有公转而无自转
Planetary gear ratio calculation methods are relative speed method, torque analysis method, velocity diagram method and vector illustration method. One of the most commonly used is the relative speed method. When we opened the door to Chengdu East Railway Station, we adopted Tujia Method for teaching. Workers, peasants and soldiers think it is more intuitive and easy to understand, especially for brief introduction. Planetary planetary gear planetary gear with the revolving axis, but also for orbiting shaft rotation, the central wheel speed can be regarded as the planetary gear rotation and rotation composite. In this paper, the graph addition is to decompose the planet gear into planets that only revolve without rotation
