Unitized cage for cylindrical roller bearing

Abstract

A unitized cage (A) for cylindrical roller bearings wherein the inner raceway of the bearing configuration may be the rotating or stationary shaft component and the outer raceway of the bearing configuration may be the rotating or stationary housing component. Thus, a bearing configuration can be generated without the need for a separate inner or outer race having inner or outer raceways. The unitized cage (A) comprises a cage nest (1) having end face axial projections (3) and a cage finger ring (2) having fingers (11) which engage the end face axial projections (3) to lock the cage nest (1) into position on the cage finger ring (2). A plurality of cylindrical rollers (7) can be positioned within the cage pockets (6) of the cage nest (1) prior to the assembly of the cage nest (1) with the cage finger ring (2) to generate a cylindrical roller bearing.

Description

[0001] Cross References to Related Applications [0002] This application is related to, and claims priority from, US Nonprovisional Patent Application No. 10 / 199,264, filed July 19, 2002. technical field [0003] The present invention relates generally to a cage for a roller bearing, and more particularly, to a composite cage for a cylindrical roller bearing. Background technique [0004] In applications where the bearing shaft and housing can be hardened and polished to roller bearing specifications, the use of cylindrical rollers without inner and outer rings can reduce profile height and weight requirements for power transmission components. In such applications, the inner and outer rings are not required because the bearing races normally found in the inner and outer rings are now seated on the surface of the shaft or housing for the bearing. [0005] A typical application for this configuration is a heavy industrial planetary gearbox, where the planet pins and gear bo...

Problems solved by technology

[0009] Other previous constructions use two pins without a machined divider, however, manufacturing with a welding operation of the pins is still expensive

Other previous structures required complex forming of metal sheets that may not have the strength to maintain their shape during harsh handling and were expensive to manufacture due to the complex shape
