Abstract

Dynamic characteristics of ball bearings with different cage pocket shapes are investigated with consideration to the concurrent rotation of the inner and outer rings. Contact models of balls with cylindrical, elongated cylindrical, and rectangular pockets are established. The ball excursion, cage trajectory, contact force, and cage speed are analyzed. The results show that the elongated cylindrical pocket leads to a more stable trajectory of the cage since balls always impact the leading side of the pocket. However, for the cylindrical and rectangular cage pockets, both the leading and trailing sides of the pockets are randomly impacted by balls, which may cause chaotic motions of the cage.
