Abstract

A bearing assembly includes a roller bearing connected with a plate-shaped bearing support. The bearing support has a receiving bore for an outer ring of the roller bearing, and the outer ring of the roller bearing is affixed to the bearing support with two affixing plates that are fixed to first and second end sides of the bearing support. The two affixing plates clamp the outer ring at two clamping surfaces. An axial spacing of the first and second end sides of the bearing support is smaller than an axial spacing of the clamping surfaces of the outer ring, and a spring element configured to act in the axial direction is disposed between one of the two affixing plates and the bearing support.

First claim

The invention claimed is:

1. A bearing assembly comprising at least one roller bearing connected with at least one bearing support that is plate-shaped at least in a section, wherein the bearing support has a receiving bore for an outer ring of the roller bearing, wherein the outer ring of the roller bearing is affixed to the bearing support with two affixing plates that are fixed to first and second end sides of the bearing support, wherein the two affixing plates clamp the outer ring at two clamping surfaces, wherein a spacing (X), measured in an axial direction (a), of the first and second end sides of the bearing support is smaller than a spacing (Y), measured in the axial direction (a), of the clamping surfaces of the outer ring,
and wherein a spring element configured to act in the axial direction (a) is disposed between one of the two affixing plates and the bearing support.

2. The bearing assembly according to claim 1 , wherein the spring element is an O-ring.

3. The bearing assembly according to claim 1 , wherein the spring element is a disk spring or a disk spring assembly.

4. The bearing assembly according to claim 1 , wherein the spring element comprises a portion of one of the two affixing plates.

5. The bearing assembly according to claim 1 , wherein the spring element is composed of spring steel.

6. The bearing assembly according to claim 1 , wherein the spring element is composed of plastic or rubber.

7. The bearing assembly according to claim 1 , wherein the two affixing plates have a different mechanical strength.

8. The bearing assembly according to claim 1 , wherein a ratio of the spacing (X) of the first and second end sides of the bearing support to the spacing (Y) of the clamping surfaces of the outer ring is from 0.90 to 0.995.

9. The bearing assembly according to claim 1 , wherein the two affixing plates are affixed to the bearing support by bolts.

10. The bearing assembly according to claim 1 , wherein one of the two affixing plates is captively connected with the outer ring of the roller bearing and disposed in a groove in an end-side area of the outer ring.

11. The bearing assembly according to claim 1 , wherein a ratio of the spacing (X) of the first and second end sides of the bearing support to the spacing (Y) of the clamping surfaces of the outer ring is from 0.975 to 0.995.

12. The bearing assembly according to claim 1 ,
wherein the spring element comprises a plastic O-ring or a rubber O-ring,
wherein the two affixing plates have a different mechanical strength,
wherein a ratio of the spacing (X) of the first and second end sides of the bearing support to the spacing (Y) of the clamping surfaces of the outer ring is from 0.90 to 0.995,
wherein the two affixing plates are affixed to the bearing support by bolts, and
wherein one of the two affixing plates is captively connected with the outer ring of the roller bearing and disposed in a groove in an end-side area of the outer ring.

13. A bearing assembly comprising:
a bearing support including a plate-shaped section and a receiving bore;
a roller bearing having an outer ring having first and second clamping surfaces;
first and second affixing plates fixing the first and second clamping surfaces of the roller bearing at the plate-shaped section of the bearing support; and
a spring element disposed against the bearing support, and
wherein an axial width of the plate-shaped section of the bearing support is less than an axial separation of the first and second clamping surfaces of the outer ring.

14. A bearing assembly comprising:
a bearing support including a plate-shaped section and a receiving bore;
a roller bearing having an outer ring having first and second clamping surfaces;
first and second affixing plates fixing the first and second clamping surfaces of the roller bearing at the plate-shaped section of the bearing support; and
a spring element disposed between the first affixing plate and the bearing support, and
wherein an axial width of the plate-shaped section of the bearing support is less than an axial separation of the first and second clamping surfaces of the outer ring.
