Abstract

A rolling-element bearing assembly includes a bearing ring and a flange. The bearing ring has a surface including at least one circumferential groove extending at least partially around the bearing ring, and the flange projects radially inwardly or radially outwardly from the surface and has a flange section at a radially inner edge or radially outer edge of the flange that projects into the groove. A hardened casting material secures the flange to the surface.

First claim

1 . A rolling-element bearing assembly, comprising:
a bearing ring including at least one groove disposed on a circumference of the bearing ring and extending along the circumference; a flange adjacent to the bearing ring in a radial direction including at least one flange section extending, in a connecting region, in the radial direction ( 16 at least partially into the groove; and a hardened casting material in the connection region.

2 . The rolling-element bearing assembly according to claim 1 , wherein the hardened casting material is connected in an interference-fit- or materially-bonded-manner at least to the flange section adjacent to the groove and to the region of the flange adjacent to the groove.

3 . The rolling-element bearing assembly according to claim 1 , wherein the groove completely encircles the bearing ring.

4 . The rolling-element bearing assembly according to claim 1 , wherein the hardened casting material extends at least partially into the groove.

5 . A method for manufacturing a rolling-element bearing including a flange, comprising:
providing a bearing ring including at least one groove disposed on a circumference of the bearing ring and extending along the circumference; providing a flange including at least one flange section configured to connect the flange to the bearing ring at a radially inner or radially outer end of the flange; disposing the flange section adjacent to the groove at a radial distance from the groove and fixing the flange relative to the bearing ring; deforming a material of the flange in the flange section such that the material of the flange is displaced by the deforming and the flange section moves at least partially into the groove; and applying a hardening casting material to a region where the flange section extends into the groove while the flange is held in a deformed state.

6 . The method according to claim 5 , wherein the flange section includes an elevation extending away from a plane of the flange in an axial direction and wherein the deforming comprises pressing the elevation toward the plane of the flange.

7 . The method according to claim 5 , wherein the flange is fixed with respect to the bearing ring using a closing tool form.

8 . The method according to claim 7 , wherein the flange is deformed by a stamp form movable with respect to a base form of the closing tool form.

9 . The rolling-element bearing assembly according to claim 1 ,
wherein the hardened casting material is connected in an interference-fit- or materially-bonded-manner at least to the flange section adjacent to the groove and to the region of the flange-adjacent to the groove, wherein the groove completely encircles the bearing ring, and wherein the hardened casting material extends at least partially into the groove.

10 . A rolling-element bearing assembly, comprising:
a bearing ring having a surface including at least one circumferential groove extending at least partially around the bearing ring; a flange projecting radially inwardly or radially outwardly from the surface, the flange having a flange section at a radially inner edge or radially outer edge of the flange, the flange section projecting into the groove, and a hardened casting material securing the flange to the surface.

11 . The rolling element bearing assembly according to claim 10 , wherein the at least one groove completely encircles the bearing ring.

12 . The rolling element bearing assembly according to claim 10 , wherein the hardened casting material extends into the at least one groove.

13 . The rolling element bearing assembly according to claim 10 , wherein the flange section comprises at least one tab projecting radially inwardly from the inner edge of the flange.

14 . The rolling element bearing assembly according to claim 10 , wherein the flange section comprises a continuous annular portion of the radially inner edge of the flange spaced from the flange by an elevation extending away from the flange in an axial direction.

15 . The rolling element bearing assembly according to claim 10 , wherein the groove has an axial width and the flange section has a width in the axial direction less than the axial width of the groove and wherein the hardened casting material fills an axial gap between the flange section and the groove.
