Abstract

A method for producing a composite rolling bearing (1) having a bearing flange (3) and at least one rolling bearing (4, 5) held on the bearing flange (3) by an inner ring (6, 7). In order to be able to fix the inner ring (7) on the bearing flange (3) with axial preloading without expansion, the inner ring (7) is acted upon by a holding-down device (23) that radially holds down the inner ring (7) and is preloaded against the inner ring (7) by a regulated axial force (F), and, by way of an advancing cone (21) introduced radially on the inside axially into the bearing flange (3), material (11) present on the bearing flange (3) is displaced radially towards the outside into a recessed formation (15, 16) in the inner ring (7).

Claims

1. A method for producing a composite rolling bearing having a bearing flange and at least one rolling bearing held on the bearing flange by an inner ring, the method comprising:

providing the inner ring on a portion of the bearing flange;

acting on the inner ring by a holding-down device of a tool radially holding down the inner ring and preloaded against the inner ring by a controlled axial force; and

displacing, by way of a feed cone introduced radially on an inside of the bearing flange axially into the bearing flange, a reserve material at the portion of the bearing flange radially outwardly into a recessed formation in the inner ring, the portion of the bearing flange including an outermost inner diameter and the reserve material protruding radially inward from the outermost inner diameter before the displacing, the inner ring including an innermost inner diameter and being offset radially outward from the innermost inner diameter at the recessed formation before the displacing,

wherein the reserve material includes a material overhang formed radially on the inside of the bearing flange at an axial distance from one end of the bearing flange, the recessed formation being at an axial distance from one end of the inner ring, the material overhang being displaced into the recessed formation.

2. The method as recited in claim 1 wherein the tool includes rollers arranged rotatably on the feed cone, the reserve material being displaced at least partially by the rollers, an initiating of the displacing of the reserve material being performed by the roller contacting the reserve material without contacting the outermost inner diameter.

3. The method as recited in claim 2 wherein an angle of inclination between an axis of rotation of the rollers of the feed cone and an axis of rotation of the composite rolling bearing is set in accordance with a radial variation in an axial width of the reserve material.

4. The method as recited in claim 1 wherein the holding-down device is centered on a centering chamfer provided radially on an outside of the inner ring.

5. The method as recited in claim 1 wherein the holding-down device fits over the inner ring radially on an inside of the inner ring and radially on an outside of the inner ring.

6. The method as recited in claim 1 wherein an annular collar is formed at an end of the bearing flange at an axial distance from an end of the inner ring.

7. The method as recited in claim 6 wherein end toothing is introduced into the annular collar.

8. A method for producing a composite rolling bearing having a bearing flange and at least one rolling bearing held on the bearing flange by an inner ring, the method comprising:

providing the inner ring on a portion of the bearing flange;

acting on the inner ring by a holding-down device of a tool radially holding down the inner ring and preloaded against the inner ring by a controlled axial force; and

displacing, by way of a feed cone introduced radially on an inside of the bearing flange axially into the bearing flange, a reserve material at the portion of the bearing flange radially outwardly into a recessed formation in the inner ring, the portion of the bearing flange including an outermost inner diameter and the reserve material protruding radially inward from the outermost inner diameter before the displacing, the inner ring including an innermost inner diameter and being offset radially outward from the innermost inner diameter at the recessed formation before the displacing,

wherein a radially extending wall of the holding-down device and the recessed formation delimit a space receiving the reserve material during the displacing.

9. The method as recited in claim 8 wherein the reserve material includes a material overhang formed radially on the inside of the bearing flange on one end of the bearing flange, the recessed formation being a chamfer radially on an inside of the inner ring on one end of the inner ring, the material overhang being displaced into the chamfer.

10. The method as recited in 8 wherein the tool includes rollers arranged rotatably on the feed cone, the reserve material being displaced at least partially by the rollers, an initiating of the displacing of the reserve material being performed by the roller contacting the reserve material without contacting the outermost inner diameter.

11. The method as recited in 10 wherein an angle of inclination between an axis of rotation of the rollers of the feed cone and an axis of rotation of the composite rolling bearing is set in accordance with a radial variation in an axial width of the reserve material.

12. The method as recited in 8 wherein the holding-down device is centered on a centering chamfer provided radially on an outside of the inner ring.

13. The method as recited in 8 wherein the holding-down device fits over the inner ring radially on an inside of the inner ring and radially on an outside of the inner ring.

14. The method as recited in 8 wherein an annular collar is formed at an end of the bearing flange at an axial distance from an end of the inner ring.

15. The method as recited in 14 wherein end toothing is introduced into the annular collar.

16. A method for producing a composite rolling bearing having a bearing flange and at least one rolling bearing held on the bearing flange by an inner ring, the method comprising:

providing the inner ring on a portion of the bearing flange;

acting on the inner ring by a holding-down device radially holding down the inner ring and preloaded against the inner ring by a controlled axial force; and

displacing, by way of a feed cone introduced radially on an inside of the bearing flange axially into the bearing flange, a reserve material at the portion of the bearing flange radially outwardly into a recessed formation in the inner ring, the portion of the bearing flange including an outermost inner diameter and the reserve material protruding radially inward from the outermost inner diameter before the displacing, the inner ring including an innermost inner diameter and being offset radially outward from the innermost inner diameter at the recessed formation before the displacing,

wherein the holding-down device fits over the inner ring radially on an inside of the inner ring and radially on an outside of the inner ring.
