Abstract
The invention concerns a rolling bearing cage (,) made of a resilient plastic and comprising at at least one peripheral point, an axially extending gap (,) formed by a first cage end (,) and a second cage end (,) which is spaced from the first cage end (,), each of the first and the second cage ends (,) comprising at least one projection and at least one recess, said recess and projection having complementary shapes, and as viewed in axial direction, the recess and the projection partially engage each other, and as viewed in peripheral direction, the recess and the projection partially overlap each other. The novel cage of the invention is characterized in that, as seen in a radial top view of the gap (,), limiting surfaces (,) of the projection (,) and the recess (,) situated opposite each other in axial direction on two sides of the gap are inclined relative to end faces (,) of the cage (,) so that a dovetail profile is formed which enables the two cage ends (,) to be displaceable relative to each other in peripheral direction, so that an expansion of the cage (,) is stopped when the limiting surfaces (,) situated opposite each other in axial direction bear against each other and a compression of the cage is stopped when limiting surfaces (,) of the projection (,) and the recess (,) situated opposite each other in peripheral direction bear against each other. In this way, a cage (,) is created that allows almost no axial and no radial offset between the two ends (,) of the cage but permits an exactly defined displacement of the cage ends (,) in both peripheral directions.
