Abstract: The disclosure relates to a main shaft of a wind turbine with mounting segments. The main shaft includes a shaft portion and a disc portion. The disc portion includes a coupling surface, a hollow portion, and an alignment portion. The alignment portion is characterized by one or more mounting segments coupled with the alignment portion. The mounting segments are configured to align a component of the wind turbine with the central axis of the main shaft. Further, the one or more mounting segments are coupled to the alignment portion using at least one fastening device. The mounting segments have a thickness ‘t’ that may be constant or varied based on the component 32 of the wind turbine coupled to the main shaft.

Abstract: A reinforced pitch bearing of a wind turbine having a first reinforcement plate and a second reinforcement plate is provided. The pitch bearing includes an outer bearing ring and an inner bearing ring, whereby both bearing rings are arranged coaxially to each other, thus comprising a common axis of symmetry. The first reinforcement plate is arranged at a first axial end of the pitch and the second reinforcement plate is arranged at a second axial end of the pitch bearing. The reinforcement plates are arranged substantially parallel to each other and the pitch bearing includes further means for reinforcement arranged in between the first reinforcement plate and the second reinforcement plate. The invention also relates to a wind turbine having at least one rotor blade and at least one pitch bearing, pivotably connecting the rotor with a hub of the wind turbine.

Abstract: An improved flange in a wind turbine is provided. The flange has a flange plate that is connected to a part of the wind turbine. The flange plate and the part of the wind turbine are connected via an edge to form an L-shaped flange. The flange plate includes a connection side to be detachable connected to a counterpart. The flange plate includes a plurality of holes to be used with a connector when the flange is connected to the counterpart. A recess is arranged in the surface of the connection side between the edge of the flange plate and the plurality of holes, to reduce fatigue loads in the area of the holes of the flange plate.
