Title
(EN) IMPROVEMENTS RELATING TO ELECTRICAL POWER GENERATORS FOR WIND TURBINES
(FR) AMÉLIORATIONS CONCERNANT DES GÉNÉRATEURS ÉLECTRIQUES POUR ÉOLIENNES
Abstract
(EN)
There is provided a method (100) of installing a pitch tube (27) into an electrical power generator (24) for a wind turbine, the method comprising: installing (105a) the pitch tube (27) so that it is coaxial with a rotational axis (R) of the generator (24); supporting (105b) a bearing arrangement (50) associated with the pitch tube (27) at an end of the generator (24) using one or more primary supports (52), wherein each of the primary supports (52) comprises a first end (58) connected to the bearing arrangement (50) and a second end (60) connected to a component (32) associated with a rotating reference frame of the generator (24); and supporting (110) the bearing arrangement (50) using one or more secondary supports (54), wherein each of the secondary supports (54) comprises a first end (62) connected to the bearing arrangement (50) and a second end (64) connected to a component (42) associated with a stationary reference frame of the generator (24).
