Abstract

The invention relates to a slide bearing set ( 4 ), comprising a slide bearing combination consisting of a radial bearing ( 6 ) with a radial bearing slide surface ( 7 ) and comprising a first axial bearing ( 8 ) with an axial bearing slide surface ( 9 ), wherein the first axial bearing ( 8 ) is arranged next to the radial bearing ( 6 ) in an axial direction ( 10 ), and with a lubricant supply device, which comprises a supply line ( 20 ) for a lubricant to the radial bearing slide surface ( 7 ) of the radial bearing ( 6 ). At least one first transversal groove ( 22 ) is disposed in the radial bearing ( 6 ) such that at least one part of the lubricant is deviated towards the first axial bearing ( 8 ) and the first axial bearing ( 8 ) can be supplied with the lubricant solely via the radial bearing ( 6 ).

First claim

The invention claimed is:

1. A slide bearing set comprising a slide bearing combination comprising a radial bearing with a radial bearing slide surface and comprising a first axial bearing with an axial bearing slide surface, wherein the first axial bearing is arranged next to the radial bearing in an axial direction, and with a lubricant supply device, which comprises a supply line for a lubricant to the radial bearing slide surface of the radial bearing, wherein at least one first transversal groove is disposed in the radial bearing such that at least a portion of the lubricant is diverted towards the first axial bearing and the first axial bearing is supplied with the lubricant solely via the radial bearing.

2. The slide bearing set as claimed in claim 1 , further comprising a second axial bearing wherein the second axial bearing is also arranged next to the radial bearing and is separated from the first axial bearing by the radial bearing.

3. The slide bearing set as claimed in claim 2 , wherein the second axial bearing is supplied with lubricant solely via the radial bearing via at least one second transversal groove.

4. The slide bearing set as claimed in claim 3 , wherein the at least one first transversal groove is designed to be asymmetric to the at least one second transversal groove.

5. The slide bearing set as claimed in claim 4 , wherein the at least one first transversal groove has a smaller flow cross section than the at least one second transversal groove.

6. The slide bearing set as claimed in claim 3 , wherein the at least one first transversal groove is formed in a circumferential direction of the radial bearing and offset by a predefinable angle to the at least one second transversal groove.

7. The slide bearing set as claimed in claim 2 , wherein the first axial bearing forms a first lubricant gap and the second axial bearing forms a second lubricant gap, wherein the first lubricant gap has smaller flow cross section than the second lubricant gap.

8. The slide bearing set as claimed in claim 2 , wherein the first and the second axial bearing are arranged directly adjacent to the radial bearing.

9. The slide bearing set as claimed in claim 1 , wherein the radial bearing is divided into two partly radial slide bearings arranged next to one another in axial direction.

10. A wind turbine gear mechanism comprising at least one gear wheel, which is mounted on an axle via a slide bearing set, wherein the slide bearing set is designed according to claim 1 .
