bearing ring with retaining flange

Abstract

The invention discloses a bearing ring (2) of a rolling bearing, said bearing ring having a raceway surface (4) for rolling elements and at least one flange (8) transitioning to a shoulder (6) of the bearing ring, Said flange protrudes beyond the raceway surface (4) by a height (H), wherein an open space (11) is formed between the bearing ring shoulder (6) and the flange (8), so that the flange (8) is Constructed to be independent over its entire height (H); and a rolling bearing with such a bearing ring (2) is also disclosed.

Description

technical field [0001] The invention relates to a bearing ring and a rolling bearing with such a bearing ring Background technique [0002] In general, the bearing inner ring and the bearing outer ring of rolling bearings respectively have raceway surfaces for arranging the rolling elements. Furthermore, the bearing ring can have radially arranged flanges (bords), so-called retaining flanges (Haltebord) and / or guide flanges (Führungsbord), wherein the retaining flanges are used during mounting of the bearing and / or during transport. for supporting the rolling elements, while the guide flange (especially during bearing operation) acts as an axial rolling element guide. Thus, the holding flange and / or guide flange is arranged axially close to the raceway surface of the bearing ring and limits the axial extension of the raceway surface. For cylindrical roller bearings, the rolling elements are configured as cylindrical rolling elements, and for tapered roller bearings, the...

Problems solved by technology

[0004] However, this has the disadvantage that thermal expansion of the material occurs during the induction hardening process, which is critical in the area of ​​the retaining flange, since the retaining flange and / or the shoulder of the bearing ring adjacent to the retaining flange are usually The case is not hardened and correspondingly also not heated, so that very high tensions (spannung) can occur in this region, which can lead to undesired cracks

In particular, bearing rings of tapered roller bearings, which have cross-sections that differ significantly in latitude (Breite) with respect to material strength, are hardened by induction hardening Application of significantly different heating, which may lead to crack formation
