Abstract

The invention relates to a rolling bearing cage (12) with two side rings (2) and a plurality of cage connecting beams (1), wherein the side rings (2) and the cage connecting beams (1) form a plurality of Cage cavity (8). In order to make the rolling bearing cage (12) particularly light and stable, the invention provides that, in the corners (10) of the cage pockets (8), recesses (3) are formed respectively, which are directed towards their radial center (7 ) is reduced or reduced, no stop surface for the associated rolling element ( 9 ) is formed here. Furthermore, the invention relates to a method for producing a rolling bearing cage (12) according to the invention, in which it is provided that a plurality of cage pockets (8) are milled into a solid cage blank, wherein the cage pockets (8) The corners (10) of the are milled in such a way that, in the cage pockets, recesses (3) are formed in each case, which taper or become smaller towards their radial center (7), without forming for the associated rolling elements (9) stop surface.

Description

technical field

[0001] The invention relates to a rolling bearing cage with two side rings and a plurality of cage connecting beams, wherein the side rings and the cage connecting beams form a plurality of cage pockets. Furthermore, the invention relates to a method for producing such a rolling bearing cage. Background technique

[0002] Rolling bearing cages of the aforementioned type (eg for tapered roller bearings) are produced from a ring-shaped cage blank, the contours for the cage pockets being milled out. The contour of the cage cavity is determined as far as possible according to the type and size of the rolling elements used. In the case of conical or cylindrical rolling elements, the cage pockets have an approximately quadrangular contour. Recesses are usually milled into the corners of the cage pockets which prevent the rolling bodies from abutting against the corners of the cage pockets. For example, DE 10021089 B4 describes a cage for a rolling bearing, in wh...
