Rolling element cage
View Patent ↗The invention concerns a rolling element cage ( 32 ) made of a metal strip material that is profiled, stamped, cut to length, and bent into a round shape, wherein the ends of the cut-to-length strip sections are joined together by welding. In order to make it possible to influence the lubricant distribution in the bearing and the vibration characteristics of the cage and thus of the overall bearing system, according to the invention the strip section ends ( 34, 36 ) are joined together with a predetermined axial offset (a) and/or radial offset (b).
1. Rolling element cage made of a metal strip material that is profiled, stamped, cut to length, and bent into a round shape, wherein ends of cut-to-length strip sections are joined together by welding, wherein the strip section ends have a predetermined axial offset (a) and/or radial offset (b) from one another.
2. Rolling element cage according to claim 1 , wherein the cage has at least one rim section bent radially inward at essentially right angles, wherein an axial offset (a) is equal to at most half of an axial thickness (c) of the rim section.
3. Rolling element cage according to claim 1 with at least one rim section located in a circumferential surface of the cage, wherein a radial offset (b) is equal to at most half the radial thickness (d) of the rim section.
4. Rolling element cage according to any of claim 1 , wherein the rolling element cage consists of a single strip section bent into a circle, two strip section ends of which are joined to one another.
5. Rolling element cage according to any of claim 1 , wherein the rolling element cage consists of multiple strip sections in the form of segments of a circle, which are joined into a circular cage at their strip section ends.
