Cage dynamic behaviors of angular contact ball bearings with double half inner rings under misalignment and skewness angle conditions

A dynamic model is established for angular contact ball bearings with double half inner rings incorporating misalignment and skewness conditions. Cage dynamics, including collisions, motion, and stability, are analyzed. Results show that increasing misalignment or skewness angles suddenly increases the normal force between the cage and the outer ring and intensifies the impact between pockets and balls. Higher axial load on the inner ring reduces the cage whirl ratio. However, significant differences in the density of the normal force between the left and right sides of the cage-outer ring occur, potentially causing the cage to experience eccentric wear. Silicon nitride balls reduce the impact between pockets and balls under misalignment and skewness conditions and decrease the normal force between the outer ring and one side of the cage.
