Abstract
A wind turbine is provided comprising a rotatable main shaft having a centre axis and being at least indirectly connected to a wind turbine rotor of the turbine and a main bearing supporting the rotatable main shaft at least indirectly against a first stationary part of the turbine, wherein fastening unit are provided for fastening the rotor to the first or a second stationary part of the turbine during replacement of the main bearing and tappet unit are provided which are able to act on the main bearing and permit a movement of the main bearing relatively to the first stationary part in the direction of the centre axis. A method for replacement of a main bearing is also provided.

27. A method for replacement of a main bearing of a wind turbine comprising a rotatable main shaft with a centre axis and being at least indirectly connected to a wind turbine rotor of the wind turbine and a main bearing supporting the rotatable main shaft at least indirectly against a first stationary part of the wind turbine, the method comprising during a course of replacement of the main bearing:
-
connecting the first or a second stationary part to the wind turbine rotor for fastening the wind turbine rotor; releasing the connection between the wind turbine rotor and the rotatable main shaft; releasing the connection between the main bearing and the first stationary part; and moving, for replacement of the main bearing, the main bearing or the main bearing and the rotatable main shaft, the moving is relative to the first stationary part in the direction of the centre axis. - View Dependent Claims (28, 29, 30, 31, 32)
