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:

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;

displacing, by way of a feed cone introduced radially on the inside axially into the bearing flange, reserve material on the bearing flange radially outwardly into a recessed formation in the inner ring, the reserve material, prior to the displacing, extending radially inwardly from an inner circumference of the bearing flange; and

wherein the holding-down device deforms end toothing into the bearing flange during a roll-forming process.

2. The method as recited in claim 1 wherein the reserve material is displaced at least partially by rollers arranged rotatably on the feed cone.

3. The method as recited in claim 1 wherein a material overhang formed radially on the inside on one end of the bearing flange as the reserve material is displaced into a chamfer formed radially on the inside as the recessed formation on one end of the inner ring.

4. The method as recited in claim 1 wherein a material overhang formed radially on the inside at an axial distance from one end of the bearing flange as the reserve material is displaced into the recessed formation at an axial distance from one end of the inner ring.

5. The method as recited in claim 1 wherein an angle of inclination between an axis of rotation of rollers of the feed cone and the axis of rotation of the composite rolling bearing is set in accordance with a radial variation in an axial width of the reserve material.
