摘要：
Due to the presence of clearances in the gearing of 3K planetary gear reducers, transmission clearances were introduced into the transmission chain, resulting in a decrease in transmission accuracy and causing impacts during driving direction changes. By utilizing the characteristics that the carrier did not participate in torque transmission in 3K planetary gear transmission, a flexible planeta- ry carrier was innovatively proposed to eliminate clearances of 3K planetary gear reducers, and the ef fectiveness of the proposed clearance elimination mechanisms was verified through simulation analysis. Gear matching and efficiency optimization were performed to achieve high forward and backward driv- ing efficiency. Through the development of a prototype and testing of transmission accuracy, hystere- sis characteristics, sinusoidal response error, transmission efficiency, and reverse starting torque, the effectiveness of the proposed flexible planetary carrier in eliminating clearances, transmission accuracy improvement, transmission efficiency and reverse transmission performance promoting was verified. © 2024 Chinese Mechanical Engineering Society.
