RETAINING CAGES FOR ROLLING ELEMENTS IN BEARINGS

摘要

A bearing cage is formed from a single piece of sheet metal with a number of windows adapted to retain respective rolling elements against movement in the sense of the bearing load. The cage is formed integrally with a number of pairs of wings folded towards the rolling elements so as to retain them in the respective windows in a sense opposite that of the normal bearing load, so that the rolling elements, located in the windows by spring action, are trapped therein. The construction is described for bearings of both the radially loaded and axially loaded type.
