Abstract

A rolling bearing comprising an inner ring, an outer ring and rolling elements arranged between the inner and the outer ring. At least one of the inner and outer rings includes a housing, two half-raceways mounted in the housing, each of the half-raceways comprising a contact surface adapted to make a contact with the rolling elements, and at least one pre-stressing element arranged between the housing and one of the half-raceways. The half-raceways are formed by frustoconical rings and the contact surfaces of the half-raceways are frustoconical.

First claim

What is claimed is:

1 . A rolling bearing comprising:
an inner ring; an outer ring; and rolling elements arranged between the inner and the outer ring, at least one of the inner and outer rings comprising:
a housing,
two half-raceways mounted in the housing, each of the half-raceways comprising a contact surface adapted to make a contact with the rolling elements, and
at least one pre-stressing element arranged between the housing and one of the half-raceways,
wherein the half-raceways are formed by frustoconical rings, and wherein the contact surfaces of the half-raceways are frustoconical.

2 . The rolling bearing according to claim 1 , wherein the rolling elements are balls.

3 . The rolling bearing according to claim 1 , the housing further comprising at least one retaining portion adapted to retain the pre-stressing element.

4 . The rolling bearing according to claim 3 , wherein the retaining portion is inclined toward the rolling elements.

5 . The rolling bearing according to claim 1 , further comprising a cage,
wherein the cage is adapted to keep the rolling elements angularly spaced.

6 . The rolling bearing according to claim 5 , wherein the cage is arranged radially between one of the half-raceways of one of the rings of the bearing and the other ring of the bearing.

7 . The rolling bearing according to claim 1 , wherein the pre-stressing element is an elastomeric ring.

8 . The rolling bearing according to claim 1 , wherein the pre-stressing element is a wave spring.

9 . The rolling bearing according to claim 1 , wherein the half-raceways are made from stamped metal sheets.

10 . The rolling bearing according to claim 1 , wherein the half-raceways are made from a synthetic material, in particular a plastic material.

11 . The rolling bearing according to claim 1 , wherein the half-raceways are made from a plastic material.

12 . The rolling bearing according to claim 1 , the housing further comprising a convex portion, wherein the convex portion is in contact with one of the half-raceways.

13 . The rolling bearing according to claim 1 , wherein the ring of the bearing which comprises half-raceways further includes two pre-stressing elements.

13 . The rolling bearing according to claim 1 , wherein both rings of the rolling bearing comprise a housing, two half-raceways and at least one pre-stressing element.
