Flexible-body Dynamics Analysis on Cage of High-speed Angular Contact Ball Bearing

A dynamic analysis method for the flexible cage dynamic formula of high-speed angular contact ball bearing was described.The flexible cage dynamic formula of high-speed angular contact ball bearing computational formulation was established using a modified Craig-Bampton component mode synthesis method based on angular contact ball bearing dynamics analysis.The dynamic characteristics of cage of high-speed angular contact ball bearing was analyzed using rigid-flexible multi-body dynamic analysis program ADAMS,and was verified by the computation example of Gupta.The results show that the rotary smoothness of cage will be broken if the ratio of pocket clearance to guided clearance and the ratio of radial load to axial load become too large or too small.The flexible cage runs more smoothly compared to the rigid cage.
