Rolling-element bearing cage and method for producing a rolling-element bearing cage
Abstract:
A rolling-element bearing cage (12) having two lateral rings (2) and a plurality of cage webs (1), wherein the laterals rings (2) and the cage webs (1) form a plurality of cage pockets (8). In order for the rolling-element bearing cage (12) to have an especially light and stable design, a respective recess (3) is formed in each of the corners (10) of the cage pockets (8). This recess is tapered or reduced toward the radial center (7) of the recess without forming a running surface for the associated rolling element (9). A method for producing the rolling-element bearing cage (12) is also provided, wherein a plurality of cage pockets (8) are milled into a solid cage blank, wherein the corners (10) of the cage pockets (8) are milled in such a way that a respective recess (3) is formed in each of the corners of the cage pockets, which recess is tapered or reduced toward the radial center (7) of the recess without forming a running surface for the associated rolling element (9).
