3. The sliding bearing according to claim 1 , wherein the first bearing shell is a stationary part of the sliding bearing.
4. The sliding bearing according to claim 3 , wherein the opening in the first bearing shell is located in an area of the bearing where there is a minimum of load present in the bearing between the first bearing shell and the second bearing shell.
5. The sliding bearing according to claim 3 , wherein the second bearing shell is a rotating part of the sliding bearing and wherein the bearing pads are connected to the rotating part while a surface of the first bearing shell is used as a sliding surface for the bearing pads.
6. The sliding bearing according to claim 1 ,
wherein the first bearing shell is a rotating part of the bearing, and the second bearing shell is a stationary part of the bearing and
wherein the bearing pads are connected to the stationary part of the bearing, while a surface of the rotatable part of the bearing is used as a sliding surface for the bearing pads.
7. The sliding bearing according to claim 1 , wherein the cover plate comprises a sealing that is arranged such that the sealing is in contact with the cover plate and the first bearing shell when the cover plate is in the closed position, so that the sealing at least partially seals the gap between the first bearing shell and the cover plate.
8. A wind turbine comprising:
a hub; and
a sliding bearing according to claim 1 connected to the hub.
9. A sliding bearing, comprising:
a first bearing shell,
a second bearing shell,
a plurality of bearing pads arranged between the first bearing shell and the second bearing shell,
an opening in the first bearing shell,
wherein the opening is arranged such that the bearing pads are visible through the opening,
wherein a bearing pad comprises a carrier body, which is removably connected to a surface, and a liner that is connected to the carrier body and provides a surface capable to move along the sliding surface.
10. A wind turbine comprising:
a hub; and
a sliding bearing according to claim 9 connected to the hub.
11. The sliding bearing according to claim 9 ,
wherein the first bearing shell comprises an inner surface that faces the second bearing shell and an outer surface that faces away from the second bearing shell,
wherein the opening is a through hole leading from the outer surface to the inner surface of the first bearing shell.
12. The sliding bearing according to claim 9 , wherein the first bearing shell is a stationary part of the sliding bearing.
13. The sliding bearing according to claim 12 , wherein the opening in the first bearing shell is located in an area of the bearing where there is a minimum of load present in the bearing between the first bearing shell and the second bearing shell.
14. The sliding bearing according to claim 12 , wherein the second bearing shell is a rotating part of the sliding bearing and wherein the bearing pads are connected to the rotating part while a surface of the first bearing shell is used as a sliding surface for the bearing pads.
15. The sliding bearing according to claim 9 ,
wherein the first bearing shell is a rotating part of the bearing, and the second bearing shell is a stationary part of the bearing and
wherein the bearing pads are connected to the stationary part of the bearing, while a surface of the rotatable part of the bearing is used as a sliding surface for the bearing pads.
16. The sliding bearing according to claim 9 ,
wherein a cover plate is provided to close the opening in the first bearing shell,
wherein the cover plate comprises a surface that is prepared to be used as a sliding surface and that fills at least a part of the opening in the sliding surface of the first bearing shell and complements to the sliding surface of the bearing shell when the cover plate is in a closed position.
17. The sliding bearing according to claim 16 ,
wherein the cover plate comprises a sealing that is arranged such that the sealing is in contact with the cover plate and the first bearing shell when the cover plate is in the closed position, so that the sealing at least partially seals the gap between the first bearing shell and the cover plate.
