Abstract
Described herein is a rolling bearing having two concentric raceways between which there are provided, in a bearing gap, a plurality of rolling bodies which roll on at least two tracks, wherein intermediate pieces which keep the rolling bodies spaced apart from one another are provided between the rolling bodies, wherein the intermediate pieces each comprise a central portion which is connected via connecting struts to an outer frame part surrounding the central portion, wherein the frame part takes the form of a bar structure or skeleton structure with window-like and/or door arch-like cutouts.
Claims15
A rolling bearing comprising:
- two concentric rings;
- rolling bodies which roll on at least two tracks, wherein the rolling bodies are in a curve of the at least two tracks;
- and
- intermediate pieces which keep the rolling bodies spaced apart from one another, and wherein the intermediate pieces each comprise a central portion connected via connecting struts to an outer frame part surrounding the central portion, wherein the central portion is integrally formed with the connecting struts and the outer frame part;
- wherein the outer frame part comprises one or more cutouts;
- wherein the one or more cutouts are alternately open towards opposite axial end faces of the intermediate piece and are encompassed by frame struts in a circumferential direction of the intermediate piece;
- and
- wherein the central portion in a running direction of a rolling body row transmits force between the rolling bodies that are spaced apart and abutment surfaces that keep adjacent rolling bodies spaced apart on said central portion, wherein the force is only transmitted by the central portion, wherein the connecting struts and the outer frame part does not transmit the force.
An intermediate piece for insertion between rolling bodies of a rolling bearing, comprising:
- a central portion;
- an outer frame part surrounding the central portion, wherein the outer frame part comprises with one or more cutouts;
- connecting struts connecting the central portion to the outer frame part;
- wherein the one or more cutouts are alternately open towards opposite axial end faces of the intermediate piece and are encompassed by frame struts in a circumferential direction of the intermediate piece;
- and
- wherein the central portion in a running direction of a rolling body row transmits force between the rolling bodies that are spaced apart and abutment surfaces that keep adjacent rolling bodies spaced apart on said central portion, wherein the force is only transmitted by the central portion, wherein the connecting struts and the outer frame part does not transmit the force.
