Segmented bearing retainer

摘要

A bearing cage assembly comprising of a plurality of discrete bridge elements coupled between first and second cage support wire rings having selected tensions, and conforming to the surfaces of associated rolling elements. The discrete bridge elements maintain rolling element in separation, provide rolling element retention within the bearing assembly, and function as a lubrication reservoir for grease lubricated bearings. The discrete bridge elements may be disposed between adjacent rolling elements, or may be configured to pass through axial bores of hollow rolling elements.

1. A bearing cage structure for use with a bearing assembly having a plurality of rolling elements disposed about a circumference of a race member, comprising:
a first wire support ring disposed adjacent an axially first end of the rolling elements and bearing assembly; a second wire support ring disposed adjacent an axially second end of the rolling elements and bearing assembly; and a plurality of discrete bridge elements coupled between the first and second wire support rings, each of said bridge elements configured to maintain a spacing between adjacent rolling elements and to retain said rolling elements relative to said race member; and a plurality of tubular spacers disposed on at least one of said first and second wire support rings annularly between adjacent discrete bridge elements, said tubular spacers configured to maintain a spacing between said adjacent discrete bridge elements.
