Abstract

A roller bearing that includes an outer ring, a first inner ring, and a first sealing ring that is disposed axially adjacent of the outer ring is provided. The roller bearing also includes a first retaining ring that is attached to the outer ring. The first sealing ring is fixed between the first retaining ring and a first clamping ring.

First claim

The invention claimed is:

1. A roller bearing comprising:
an outer ring,
a first inner ring,
a first sealing ring disposed axially adjacent of the outer ring, wherein a first retaining ring is attached to the outer ring, and wherein the first sealing ring is fixed between the first retaining ring and a first clamping ring.

2. The roller bearing according to claim 1 , wherein the first retaining ring is attached to the outer ring via a screw connection.

3. The roller bearing according to claim 1 , wherein the first clamping ring and the first retaining ring are attached to the outer ring by a common screw connection.

4. The roller bearing according to claim 1 , wherein the first retaining ring is attached to the outer ring by screws that also attach the outer ring to another structure.

5. The roller bearing according to claim 4 , wherein the another structure is a bearing housing.

6. A tapered roller bearing comprising:
an outer ring,
a first inner ring,
a first sealing ring disposed axially adjacent of the outer ring, wherein a first retaining ring is attached to the outer ring, and wherein the first sealing ring is fixed between the first retaining ring and a first clamping ring.

7. A wind turbine comprising:
a rotor shaft, and
a tapered roller bearing according to claim 1 rotatably supporting the rotor shaft.

8. The wind turbine according to claim 7 , further comprising a bearing housing, wherein the bearing housing is directly connected to the outer ring of the tapered roller bearing by screws.

9. A tapered roller bearing comprising:
an outer ring, wherein a radially-inner surface of the outer ring comprises a first conical track and a second conical track axially adjacent to the first conical track,
a first inner ring having a conical track,
a second inner ring having a conical track,
a first set of conically-shaped roller bodies disposed so as roll between the first conical track of the outer ring and the conical track of the first inner ring,
a second set of conically-shaped roller bodies disposed so as to roll between the second conical track of the outer ring and the conical track of second inner ring, and
a first sealing ring disposed axially adjacent the outer ring, the first sealing ring being connected with the outer ring and being in a sliding, sealed contact with a slip surface of the first inner ring, wherein the first and second set of roller bodies are disposed substantially in a V-shape as viewed in an axial cross-section with axially-adjacent ends of the first and second roller bodies being disposed radially inward of the axially-remote ends of the first and second roller bodies, wherein the first sealing ring is fixed to a first retaining ring via a first clamping ring, and wherein the first retaining ring is attached to the outer ring via a screw connection.

10. A two-row tapered roller bearing comprising:
an outer ring,
a first inner ring,
a second inner ring disposed axially adjacent the first inner ring,
a first set of conically-shaped roller bodies disposed so as roll between the outer ring and the first inner ring,
a second set of conically-shaped roller bodies disposed axially adjacent the first roller bodies and so as to roll between the outer ring and the second inner ring, and
a first sealing ring disposed axially adjacent the outer ring, the first sealing ring being connected with the outer ring and configured to slip on a slip surface of the first inner ring in a contacting manner when the first inner ring rotates, wherein
the first sealing ring is fixed to the outer ring via screws extending axially threw bores in the first sealing ring.
