Abstract
A cage for a ball bearing is optimized for high-speed applications. To reduce weight, the cage is formed by a number of conical blades which collectively form an 'X' shape. To add rigidity, a number of gussets are placed between the blades at various circumferential locations. The light weight reduces the centrifugal forces for a given diameter and rotational speed. The rigidity permits the cage to withstand the centrifugal forces without excessive deflection or stress.
