Abstract

A wind turbine has a rotor and a generator. A planetary transmission is arranged between the rotor and the generator, the planetary transmission being operatively connected to the rotor and the generator. The planetary transmission has at least one planet gear, at least one planet pin, and a planet carrier, the planet gear being arranged on the planet pin. At least one sliding bearing is arranged between the planet pin and the planet carrier, and the planet gear is rotationally fixed to the planet pin.

Claims

1-10. -10. (canceled)

11. A wind turbine with a rotor and a generator, a planetary transmission (1) being arranged between the rotor and the generator, said planetary transmission being operatively connected to the rotor and the generator, the planetary transmission (1) comprising at least one planet gear (4), at least one planet pin (7) and a planet carrier (8), the planet gear (4) being arranged on the planet pin (7), wherein at least one sliding bearing (15, 16) is arranged between the planet pin (7) and the planet carrier (8) and also the planet gear (4) is connected non-rotatably to the planet pin (7), and wherein the planet carrier (8) is configured as multiple parts and has an inner part (24) and an outer part (23) and the inner part (24) is arranged adjacent to the planet pin (7), and wherein the at least one sliding bearing (15, 16) is formed by the inner part (24) of the planet carrier (8).

12. The wind turbine as claimed in claim 11, wherein the planet pin (7) is configured in one piece with the planet gear (4).

13. The wind turbine as claimed in claim 11, wherein the planet pin (7) is configured as multiple parts and comprises a central part (31) and a first and a second side part (32, 33), and wherein the central part (31) is formed by the planet gear (4).

14. The wind turbine as claimed in claim 11, wherein between the at least one sliding bearing (15, 16) and the planet gear (4) a stop disc (19, 20) is arranged.

15. The wind turbine as claimed in claim 11, wherein the inner part (24) is connected to the outer part (23).

16. The wind turbine as claimed in claim 15, wherein the connection of the inner part (24) to the outer part (23) is formed by a connecting element (25), which has its largest dimension in axial direction of the planet gear (4).

17. The wind turbine as claimed in claim 15, wherein the inner part (24) is connected to the outer part (23) in a form-fitting manner.

18. The wind turbine as claimed in claim 11, wherein the at least one sliding bearing (15, 16) is configured as a sliding bearing bush.
