【Abstract】 A convenient algorithm for the power flow of closed epicyclic gear train was proposed. It could ascertain whether the power flow backwards exists or not by the signs of the absolute and relative transmission ratio. The power flow backwards could also be avoided by changing the external mesh times of fixed-axis gear train, or by changing the number of gear tooth. The algorithm deduced perspicuity, its conclusion was simple and convenient because it avoided computing fussy train transmission ratio to decide whether the power flow backwards existed or not. The algorithm has great useful value for deciding the rationality of the structure of closed epicyclic gear train.更多还原
