| Abstract: | 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. |
