摘要

根据行星轮系的传动原理,提出了一种采用信号流图的方法计算复杂行星轮系的转矩。将行星轮系传动链的结构特征与信号流的传递特性相结合,建立了XP型、PX型、T型、∏型和E型行星轮系混联系统的信号流图模型。再利用信号流图的计算规则,将这些行星轮系的拓扑图模型进行简化计算,获得了各种混联系统输入、输出轴及系统内部各构件的转矩等特性参数的计算关系式。该方法具有较好的直观性和计算高效性,为复杂行星轮系传动特性参数计算等方面的研究提供了一种新方法。

Abstract

Based on the transmission principle of planetary gear train,a method by using the signal flow graph is proposed to calculate the torque of complex planetary gear train. By combining the structure characteristics of transmission chain of planetary gear train with the transfer characteristic of signal flow,the signal flow graph models of compound system of XP type,PX type,T type,∏ type and E type of planetary gear train are established. The signal flow graph is used to simplify the calculation of topology model by using signal flow graph,the calculation formula of characteristic parameters for each component is obtained. The results show that this method has good visibility and high efficiency,a new method for the parameter calculation of complex planetary gear train is provided.
