Roller cages formed from apertured separators for roller bearings

Abstract

A roller cage for a roller bearing assembly is made from first and second apertured separators alternately interlocked in one another. Each apertured separator has a housing provided with two apertures and a roller adapted to be received in the housing through one of the apertures where it is resiliently encased. Each housing is symmetrical about the axis of revolution of the roller and has a symmetrical center at the mid height of the axis of symmetry. The first and second separators each have two part spherical surfaces symmetrical about a plane of symmetry containing the axis of the housing and the axis of the cage with the part spherical surfaces on the first separator being convex and those of the second separator being concave. The radius of curvature of the convex surfaces is equal to the radius of the concave surface so that the two separators can interlock with each other.
