Abstract：[Objective]Aiming at the lack of efficiency parameter optimization design and simulation verification for the 3K-H type(type 5310)self-locking planetary gear train,an efficiency maximization design method was proposed to develop a gear train structure with both reliable self-locking characteristics and high forward transmission efficiency,providing a reference for related engineering applications.[Methods]Firstly,a parameter-efficiency maximization model was established,the relation between efficiency and the transmission ratio of the converted gear train with different power flows was derived,and a parameter-efficiency curve was drawn to lay a foundation for efficiency optimization.Secondly,under the condition of satisfying self-locking,the transmission ratio of the converted gear train corresponding to the maximum efficiency was determined,and the gear tooth parameters were designed considering the constraints of module and pitch circle diameter.Finally,dynamic simulation was carried out using Adams software,and the effectiveness of the design scheme was verified by combining theoretical calculations.[Results]The reverse transmission efficiency of the designed gear train is less than 0,achieving reliable self-locking;the forward transmission design efficiency reaches 0.506,and the simulation efficiency is 0.481.The theoretical calculation results are highly consistent with the simulation results,verifying the feasibility and effectiveness of the design method.
