| 摘要 |
The invention concerns a wind turbine comprising a rotatable main shaft (14) having a centre axis (A) and being at least indirectly connected to a wind turbine rotor (26) of the wind turbine (1) and at least one main bearing (15, 16) supporting the rotatable main shaft (14) at least indirectly against a first stationary part (6) of the wind turbine (1), wherein fastening means (32, 33, 35) are provided for fastening the wind turbine rotor (26) to the first or a second stationary part (6) of the wind turbine (1) during replacement of the at least one main bearing (15, 16) and tappet means (30, 31, 40, 41, 50, 51) are provided which are able to act on the at least one main bearing (15, 16) and permit a movement of the at least one main bearing (15, 16) relatively to the first stationary part (6) in the direction of the centre axis (A). The invention concerns also a method for replacement of a main bearing wherein in the course of replacement of the at least one main bearing (15, 16) the at least one main bearing (15, 16) or the at least one main bearing (15, 16) and the rotatable main shaft (14) are moved relatively to the first stationary part (6) in the direction of the centre axis (A) for replacement of the at least one main bearing (15, 16). |
