摘　　要：应用离散方法 ,深入分析了两种 2K H型行星轮系的内力矩和功率流 ,发现 2K H型行星轮系属于封闭差动轮系 ;其中 ,正号机构存在循环功率流。循环功率流不仅降低了正号机构的效率 ,而且在某种情况下还会使轮系自锁。同时 ,分析了 3K型行星轮系的内力矩、功率流和自锁问题。This paper used the discretization method and thoroughly analyzed the inner torque and power-flow of two kinds of 2K-H planetary gear train. We find that 2K-H planetary gear train belongs to the planetary differential gear train, and the positive sign mechanism has circulating power load. The circulating power load reduced the efficiency of the positive sign mechanism, and the gear system will be self-locked in some conditions. Moreover, the problems on the inner torque, power-flow and self-locking of 3K planetary gear train were analyzed.

关 键 词：行星轮系 内力矩 功率流 循环功率流 自锁
