Mathematical modeling of the transmission performance of 2K–H pin cycloid planetary mechanism

A mathematical model of transmission performance of 2K–H pin-cycloid planetary mechanism with one tooth difference is proposed based on static analysis of actual meshing transmission process between gear pairs considering friction. Computer program for the output moment calculation is developed and is used to analyze the effects of the kinematics parameters on the transmission performance. With the theoretical guidance, the self-locking performance of the seat angle adjustment mechanism of an automobile is improved. The presented mathematical model also provides a basis for further investigations such as the effects of tooth profile and machining error on the transmission performance.
