Abstract
A bearing ring of a rolling-element bearing includes a raceway for rolling elements and at least one flange for guiding the rolling elements, the flange merging into a bearing ring shoulder and extending to a height above the raceway. A free space such as a recess is formed between the bearing ring shoulder and the flange such that the flange is freestanding over its entire height.
Claims16
A bearing ring of a rolling-element bearing comprising:
- a raceway for rolling elements;
- and
- at least one flange for supporting the rolling elements, the flange merging into a bearing ring shoulder and extending to a height above the raceway,
- wherein a free space is formed between the bearing ring shoulder and the flange, the free space being dimensioned such that the flange is freestanding over its entire height,
- wherein the bearing ring is an inner ring of a tapered roller bearing, wherein the flange is a retaining flange, and wherein the bearing ring shoulder and the raceway form an angle of between 100 degrees and 150 degrees;
- and wherein the bearing ring includes a guide flange for tapered rollers, and wherein the raceway and the guide flange each include an induction hardened surface, and wherein the bearing ring shoulder does not include an induction hardened surface.

A bearing ring of a tapered rolling-element bearing comprising:
- a raceway having a radially inner side and a radially outer side, the radially outer side being axially spaced from the radially inner side;
- a bearing ring shoulder radially inward of the radially outer side of the raceway and axially spaced from the radially inner side of the raceway;
- a flange at the radially inner side of the raceway configured to support rolling elements on the raceway;
- and
- a recess between the flange and the bearing ring shoulder,
- wherein the flange has a first side facing the raceway, the first side having a first length and a second side facing the recess, the second side having a second length greater than the first length, the second side forming a wall of the recess, wherein the first side is substantially parallel to the second side.
