Rolling bearing cages and rolling bearings

Abstract

The invention relates to a rolling bearing cage (10) having a plurality of loose segments (11, 12, 13, 14) arranged in the circumferential direction, wherein the segments (11, 12, 13, 14 ) has a base body (15) with at least one pocket (16) for receiving a rolling element (21). According to the invention it is provided that at least one play compensating element ( 17 ) is arranged between two adjacent base bodies ( 15 ) in the circumferential direction and that the play compensating element ( 17 ) has a higher elasticity in the circumferential direction than the base bodies ( 15 ) And the segments ( 11 , 12 , 13 , 14 ) are arranged without gaps in the circumferential direction at room temperature. The invention also relates to a rolling bearing comprising such a rolling bearing cage.

Description

technical field [0001] The invention relates to a rolling bearing cage having a plurality of loose segments arranged in the circumferential direction, wherein the segments have a base body with at least one pocket for receiving rolling bodies. The invention also relates to a rolling bearing comprising such a rolling bearing cage. Background technique [0002] Such rolling bearing cages are particularly suitable for use in so-called large rolling bearings. Large roller bearings are used, for example, in rotor bearings of wind power plants or in main bearings of tunnel boring machines and have a pitch circle diameter of greater than 600 mm, for example greater than 1000 mm or greater than 1500 mm. [0003] In large rolling bearings, however, conventional rolling bearing cages consisting of two side disks and a plurality of transverse webs connecting the side disks can also be used. However, the manufacture and assembly of such a rolling bearing cage becomes difficult as the ...

Problems solved by technology

The disadvantage of the solution of DE 102 46 825 A1 is that by imposing the required gap due to the different materials of the segments and of the bearing rings, mutual collisions cannot be avoided in principle and the segments are distributed non-uniformly and uncontrollably during operation on the circumference

The disadvantage of the solution according to DE 10 2009 014 779 A1 is that the use of metal spring elements in combination with tension-bearing coupling elements that mechanically connect the segments results in a complex and expensive construction and that the individual segments cannot be completely avoided. collide with each other
