Problems solved by technology

This damages the bearing ring and necessitates stopping the bearing operation
Also, in some bearings, threaded holes cannot be introduced due to the ring geometry, since the available ring thickness is constructed too small

Embodiment Construction

[0023] In the following, identical or functionally equivalent elements are denoted by the same reference numerals.

[0024] figure 1 and figure 2 Both schematically show a cross-sectional view of a rolling bearing 1 , the rolling bearing 1 includes a bearing inner ring 2 and a bearing outer ring 4 , and a rolling body 6 is arranged between the bearing inner ring 2 and the bearing outer ring 4 . here figure 1 The rolling bearings 1 depicted in are constructed as cylindrical roller bearings, while tapered roller bearings are figure 2 shown in . However, it is expressly noted that rolling bearings other than those shown can also be equipped according to the invention.

[0025] If it is also possible to figure 1 and figure 2 It can be seen that the bearing inner ring 2 and the bearing outer ring 4 respectively comprise an essentially axially extending bearing ring outer surface 20 ; 40 . Furthermore, the bearing inner ring 2 and the bearing outer ring 4 each have two ess...

Abstract

The invention relates to a bearing ring (2, 4) for a rolling bearing (1) with a preferably axially extending outer surface (20, 40), two preferably radially extending lateral surfaces (22, 24) and an inner surface (24, 44) which is arranged to be at least partially in contact with a bearing body (6). At least one recess (10) is formed in the inner surface (24, 44) and is designed such that the recess interacts with a lifting tool. The invention also relates to a bearing ring comprising the type of rolling bearing.

Description

technical field [0001] The present invention relates to a bearing ring for a rolling bearing and a rolling bearing including such a bearing ring according to the preamble of claim 1 of the present invention. Background technique [0002] In order to bring a rolling bearing or a rolling bearing ring into its mounting position, it is often necessary to individually lift and move the entire rolling bearing or rolling bearing ring. Especially with large rolling bearings, such as those used in wind turbines, it must be possible to lift the rolling bearing mechanically. [0003] For rolling bearings in assembled state which also comprise a two-part outer ring, such lifting and moving can be carried out without problems, since the lifting tool can easily engage in the gap formed by the two-part bearing outer ring, Thus the bearing can be lifted as a whole. However, if only a single ring is lifted or if the outer ring is manufactured in one piece, it cannot be joined on the side s...
