Abstract
The roller thrust bearing cage and roller assembly includes an annular cage with a plurality of circumferentially spaced pockets. Each of the pockets is shaped to give proper guidance to the roller when the extended center line of the roller passes through the axis of the annular cage. Preferably each pocket has two radially, inwardly converging sides and preferably, the pockets are trapezoidal. A cylindrical roller is preferably located in each of the pockets.
Claims3
An annular roller thrust bearing cage and roller assembly for use in a thrust bearing comprising:
- an annular cage having a plurality of circumferentially spaced roller pockets, and a cylindrical roller located in at least one of the pockets;
- the shape and dimensions and location of each pocket and the shape and dimensions of each roller being such that running clearance exists between the roller and the lateral walls of the pocket and each roller pocket having at least one pocket lateral wall constructed and located so that as the thrust bearing begins to rotate in a predetermined direction the cylindrical roller contacts said at least one pocket lateral wall, in guided radial alignment and the extended center line of the cylindrical roller always passes through the axis of the annular cage as the thrust bearing continues to rotate in such predetermined direction.
