| 摘 要： | 针对行星齿轮传动比计算问题,本文在分析对比已有计算方法的基础上,引入了平面运动物体的速度瞬心概念。以标准渐开线直齿轮为研究对象,对行星齿轮传动系统传动比进行求解,给出了基于速度瞬心的行星齿轮传动比推导过程,得到了各个构件之间的运动关系。与传统的机构转化求解法相比,本方法能更清楚地描述行星齿轮系中行星轮的运动状态。

| Abstract: | Aiming at the calculation of planetary gear transmission ratio,based on the analysis and comparison of existing calculation methods,the concept of instantaneous center of velocity of plane moving object is introduced.Taking the standard involute spur gear as the research object,the transmission ratio of planetary gear transmission system is solved,and the derivation process of planetary gear transmission ratio based on the instantaneous center of velocity is given,and the motion relationship between each component is obtained.Compared with the traditional mechanism transformation method,this method can describe the motion state of planetary gear train more clearly. |
