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).
L'invention concerne une éolienne qui comprend : un arbre rotatif principal (14) possédant un axe central (A) qui est au moins indirectement relié à un rotor d'éolienne (26) de l'éolienne (1); et au moins un palier principal (15, 16) soutenant au moins indirectement l'arbre rotatif principal (14) contre une première partie fixe (6) de l'éolienne (1), des moyens de fixation (32, 33, 35) permettant d'attacher le rotor d'éolienne (26) à la première ou à la seconde partie fixe (6) de l'éolienne (1) au cours du remplacement du palier principal précité (15, 16), et des moyens poussoirs (30, 31, 40, 41, 50, 51) permettant d'agir sur le palier principal précité (15, 16) et de laisser ce dernier se déplacer par rapport à la première partie fixe (6) dans le sens de l'axe central (A). L'invention se rapporte également à un procédé de remplacement de palier principal selon lequel, lors du remplacement du palier principal (15, 16), on déplace le palier principal (15, 16), ou le palier principal (15, 16) et l'arbre rotatif principal (14), par rapport à la première partie fixe (6) dans le sens de l'axe central (A) afin de remplacer le palier principal (15, 16).
