【摘要】 大多数“机械原理”教材都使用转化机构法来研究行星轮系的转速。文章介绍使用列表叠加法来计算行星轮系的转速，此法将行星轮系的运动看成是两段运动的叠加。同时还论证了此法的理论依据并指出此法的缺陷。更多还原

【Abstract】 Most "Theory of machines and mechanisms" textbooks use the converting mechanism method for calculating the rotating velocities of epicyclic gear train.This paper introduces the tabulation sum method for calculating the rotating velocities of epicyclic gear train.This method regards the motion of epicyclic gear train as the sum of two motion. The theoretical basis of this method is proved and its shortcoming is pointed out.更多还原
