无传动间隙的3K行星齿轮减速器设计OA北大核心CSTPCD

Due to the presence of clearances in the gearing of 3K planetary gear reducers,trans-mission 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.
