Abstract
A locking arrangement comprises a locking member having a longitudinal axis that is contained in a working plane where shear forces are concentrated when the locking member is in a locking position. The working plane is arranged substantially parallel to the axis of rotation of the parts to be locked when in said locking position in which at least one part of the wind turbine is prevented from being rotated relative to at least another part around said axis of rotation. A Wind turbine generator is provided having a rotor with a rotor flange portion and a stator with a stator flange portion, with both flange portions being complimentarily shaped and defining a locking housing for receiving said locking member.
