Abstract

A bearing assembly for rotatably supporting a first component with respect to a second component includes at least one bearing including a bearing ring, at least one further component, and at least one lubricant branch structure configured to carry a lubricant to the bearing and to the further component, wherein the lubricant branch structure is at least partially disposed in the bearing ring or the lubricant branch structure is at least partially disposed in a distributor piece directly abutting the bearing ring.

First claim

What is claimed is:

1. A bearing assembly for rotatably supporting a first component with respect to a second component, the bearing assembly comprising:
at least one bearing including a bearing ring having a raceway;
at least one further component; and
at least one lubricant branch structure configured to lubricate the bearing and the further component,
wherein the lubricant branch structure is at least partially disposed in the bearing ring or wherein a distributor piece abuts the bearing ring and the lubricant branch structure is at least partially disposed in the distributor piece; and
wherein the bearing ring or the distributor piece includes at least three distributor bores configured to lubricate the at least one bearing, a second bearing, and the further component.

2. The bearing assembly according to claim 1 , wherein the lubricant branch structure is at least partially disposed in the distributor piece.

3. The bearing assembly according to claim 2 , wherein the lubricant branch structure is configured to carry a lubricating medium, and wherein the at least one bearing includes at least one lubrication opening through which the lubricating medium can enter into the bearing from the distributor piece.

4. The bearing assembly according to claim 3 , wherein the distributor piece includes a first bore aligned with one of the at least one lubrication opening and/or wherein the at least one lubrication opening extends perpendicular to an axis of rotation or extends at an angle of 1° to 90° to the axis of rotation and/or the at least one lubrication opening extends to a raceway of the bearing ring.

5. The bearing assembly according to claim 2 , wherein the distributor piece radially and/or axially abuts at least sectionally on the bearing ring.

6. The bearing assembly according to claim 2 , wherein the distributor piece abuts in the axial and/or in the radial direction at least sectionally on an outer ring of the second bearing.

7. The bearing assembly according to claim 2 , wherein the bearing ring includes at least two lubrication openings, and wherein one of the at least two lubrication openings is located at an axial end surface of the bearing ring.

8. The bearing assembly according to claim 2 , wherein the bearing ring includes a first lubrication opening, a second lubrication opening and a third lubrication opening, wherein the first lubrication opening is located at a first axial end surface of the bearing ring and the second lubrication opening is located at a second axial end surface of the bearing ring opposite the first axial end surface.

9. The bearing assembly according to claim 2 ,
wherein the at least one bearing includes at least one lubrication opening through which a lubricating medium can enter into the bearing from the distributor piece,
wherein the distributor piece radially and/or axially abuts at least sectionally on the bearing ring,
wherein the distributor piece includes a first distributor bore, a second distributor bore and a third distributor bore for lubricating the at least one bearing, the second bearing, and the further component, and
wherein the first distributor bore is aligned with at least one lubrication opening.

10. The bearing assembly according to claim 1 , wherein the at least one bearing is a ball bearing and wherein the second bearing is a cylindrical roller bearing.

11. The bearing assembly according to claim 1 , wherein the lubricant branch structure is disposed entirely in the bearing ring.

12. A screw compressor including the bearing ring according to claim 1 , wherein the first component or the further component is a rotor of the screw compressor.

13. The bearing assembly according to claim 1 , wherein the lubricant branch structure is configured to carry a lubricating medium to the raceway and to dispense the lubricating medium toward the further component.

14. A bearing ring for a bearing assembly for rotatably supporting a first component with respect to a second component, the bearing ring comprising at least two distributor bores, wherein a first distributor bore of the at least two distributor bores has at least one lubrication opening located at a first axial end surface of the bearing ring.

15. A bearing assembly for rotatably supporting a first component with respect to a second component, the bearing assembly comprising:
at least one bearing including a bearing ring and a raceway;
at least one further component; and
at least one lubricant branch structure configured to lubricate the bearing and the further component,
wherein the lubricant branch structure is located entirely in the bearing ring; and
wherein the bearing ring includes a first lubrication opening, a second lubrication opening and a third lubrication opening, wherein the first lubrication opening is located at a first axial end surface of the bearing ring and the second lubrication opening is located at a second axial end surface of the bearing ring opposite the first axial end surface.

16. The bearing assembly according to claim 15 , wherein the lubricant branch structure is configured to carry a lubricating medium to the raceway and to dispense the lubricating medium toward the further component.

17. The bearing assembly according to claim 16 , including a distributor piece directly abutting the bearing ring and configured to carry the lubricating medium to the at least one lubricant branch structure.
