Abstract ∵ Pocket hole is the key structure of the bearing cage，and the shape of the pocket hole directly affects the mechanical properties. In order to improve the performance and extend the service life of the bearing cage of high-sped light-load robots，this paper takes the 62Oo deep groove ball bearing as the research object and establishes athree-dimensional modelofthe bearing cage byusing SolidWorkssoftware.Finite element analysis is used to analyze the strength and stiffnessofthecage and dynamically verify it in the Adams environment.The results show that for bearing cages of the same material and size with diferent pocket shapes （round，spherical， square），the strength and stiffess of the round pocket cage are maximized when bearing the radial load of the same size and uniform distribution. The maximum stress and displacement of both the round pocket hole cage and the square pocket hole cage appear between the pocket holeand the two end faces of the cage. The maximum stress and displacement of the spherical pocket hole cage appear inside the pocket hole.The corresponding parts can be thickened or replaced with beter materials to optimize their mechanical properties. This study can provide a reference for the optimization of the mechanical properties of bearing cages of high-speed light-load robots.
