Abstract

Spaceborne two-dimensional turntable is the main carrier of the space camera and other optoelectronic equipment, and the stability of the thin-walled angular contact ball bearings used in its shaft system will affect the control accuracy and service life of the satellite. Research on slip rate, the deviation ratio of centroid whirl velocity and vibration of bearing with different pocket clearances, outer clearances and velocity and axial loads. For 71928AC type angular contact ball bearing, when pocket clearance is between 0.30-0.40mm, outer clearance is 1.60mm, the cage of bearing has better stability. According to the experimental results, after the parameter optimization, the bearing stability is enhanced. The research results provide a theoretical basis for the optimal design of angular contact ball bearing cages.
