Experimental research on cage motion with different pocket shapes in angular contact ball bearing

Dujuan Yuan et al.

Summary: The study investigated the motion characteristics of cages with spherical, square, and cylindrical shapes in angular contact ball bearings under different operating conditions. The slip rates of all cages decrease with increasing radial load and increase with rotating speed. Furthermore, the inclination angle and slip rate of the spherical, cylindrical, and square pockets decrease in turn.

Dynamic and wear characteristics of self-lubricating bearing cage: effects of cage pocket shape

Shuai Gao et al.

Summary: This study proposes a comprehensive dynamic model for analyzing the stability, skidding degree, ball-cage collision, wear distribution, and wear rate of four types of cage pocket. Experimental results show that the cage with a combination of circle and rectangle pockets has the highest stability, while the circle pocket has a larger collision area but a higher wear rate. The combined rectangle-diamond pocket has better wear resistance.
