Abstract

A bearing having an inner ring, an outer ring, and at least one seal arranged between the rings. The bearing including a protective cover that delimits an annular space into which the seal extends and provides an outer annular portion and at least one inner portion disposed radially facing and at a distance from one another, and a connecting annular portion linking the outer annular portion and the inner portion; and at least one means for fixing the protective cover onto the inner ring, the fixing means passing through the outer and inner portions of the protective cover and cooperating with the inner ring.

First claim

The invention claimed is:

1. A bearing comprising:
an outer ring,
an inner ring, and
at least one seal arranged between the rings,
wherein a protective cover includes an outer annular portion disposed radially facing an at least one inner portion, the outer annular portion and the at least one inner portion arranged at a distance from one another, and a connecting annular portion extending between and linking the outer annular portion and the inner portion, the outer annular portion, the at least one inner portion, the connecting annular portion, and a portion of the inner ring facing the outer annular portion collectively delimiting an annular space into which at least a part of the seal extends; and
at least one fixing element for fixing the protective cover onto the inner ring,
wherein the at least one fixing element passing through the outer portion, the inner portion, and the annular space of the protective cover and cooperating with the inner ring.

2. The bearing according to claim 1 , wherein the fixing element extends radially.

3. The bearing according to claim 1 , wherein the seal is independent of the protective cover.

4. The bearing according to claim 1 , wherein the fixing element provides a screw whose head bears on an outer surface of the outer annular portion of the protective cover.

5. The bearing according to claim 1 , wherein the inner portion is adjacent to a peripheral surface of the inner ring.

6. A bearing according to claim 1 , wherein the protective cover provides a plurality of local inner portions secured to the connecting portion, the bearing including a plurality of fixing elements passing respectively through-orifices of the outer portion and of local inner portions and cooperating with the inner ring.

7. The bearing according to claim 1 , wherein the inner portion is annular.

8. The bearing according to claim 1 , wherein the connecting portion of the protective cover provides an annular inner part that is inserted into a peripheral annular groove of the inner ring.

9. The bearing according to claim 1 , wherein the outer portion and the connecting portion of the protective cover are an L-shaped section.

10. The bearing according to claim 1 , further comprising an annular axial partition extending into said annular space between the outer portion of the protective cover and the seal and mounted on the outer ring.

11. A bearing comprising:
an outer ring,
an inner ring,
at least one seal arranged between the rings,
wherein a protective cover delimits an annular space into which at least a part of the seal extends, and provides an outer annular portion and at least one inner portion disposed radially facing and at a distance from one another, and a connecting annular portion linking the outer annular portion and the inner portion;
at least one means for fixing the cover onto the inner ring, the fixing element passing through the outer and inner portions of the protective cover and cooperating with the inner ring; and
an annular axial partition extending into said annular space between the outer portion of the protective cover and the seal and mounted on the outer ring.

12. The bearing according to claim 11 , wherein the fixing element extends radially.

13. The bearing according to claim 11 , wherein the seal is independent of the protective cover.

14. The bearing according to claim 11 , wherein the fixing element provides a screw whose head bears on an outer surface of the outer annular portion of the protective cover.

15. The bearing according to claim 11 , wherein the inner portion is adjacent to a peripheral surface of the inner ring.

16. A bearing according to claim 11 , wherein the protective cover provides a plurality of local inner portions secured to the connecting portion, the bearing including a plurality of fixing elements passing respectively through-orifices of the outer portion and of local inner portions and cooperating with the inner ring.

17. The bearing according to claim 11 , wherein the inner portion is annular.

18. The bearing according to claim 11 , wherein the connecting portion of the protective cover provides an annular inner part that is inserted into a peripheral annular groove of the inner ring.

19. The bearing according to claim 11 , wherein the outer portion and the connecting portion of the protective cover are an L-shaped section.
