Abstract: A blade pitch system for a wind turbine comprising a motor coupled to a central reduction gearing, wherein a rotatable output of the central reduction gearing is fixed to a mobile link that in use is joined to the blade and allows rotation of the blade around its longitudinal axis and a static part of the central reduction gearing or the motor is fixed to a static link that in use is joined to a wind turbine hub, wherein the system further comprises one or more flexible couplings to couple the central reduction gearing or the motor and the static or the mobile link such that torque about a blade longitudinal axis is transmitted between the blade and the reduction gearing while substantially limiting the transmission of other loads.

Abstract: A wind turbine that includes a rotor and a generator is described. The rotor includes a rotor hub that is rotatably mounted on a frame and one or more rotor blades. The generator includes a generator stator and a generator rotor with a carrying structure that carries magnetic or electromagnetic elements. One or more circumferentially arranged substantially axial protrusions that extend into the generator rotor carrying structure are attached to the rotor. Flexible couplings are arranged between one or more of the axial protrusions and the carrying structure.

Abstract: Counterweight systems for a wind turbine comprising a hub mounted to a nacelle such that the hub is rotatable around a rotation axis with respect to the nacelle, the hub comprising a blade root region configured to receive a root of a blade and having a pitch system configured to rotate the blade around a pitch axis. The counterweight system comprises a beam mountable to the blade root region at a first point of the beam and a counterweight mass coupled to the beam at a second point of the beam, such that, when the beam is mounted to the blade root region, the beam is arranged substantially perpendicular to the pitch axis and the pitch system can cause the counterweight mass to rotate around the pitch axis. Methods are also provided of mounting one or more blades to a wind turbine hub by using such counterweight systems.

Abstract: Counterweight system for a wind turbine comprising a hub mounted to a nacelle such that the hub is rotatable around a rotation axis with respect to the nacelle. The counterweight system comprises: a mechanical unit comprising a fixed part and a rotatable part, the fixed part being mountable to the hub in such a way that the rotatable part is rotatable with respect to the hub substantially around the rotation axis of the hub; a drive unit for causing rotation of the rotatable part; a beam coupled to the rotatable part at a first point of the beam in such a way that the beam is arranged substantially perpendicular to the rotation axis of the hub; and a counterweight mass coupled to the beam at a second point of the beam. A method of mounting a blade to a hub by using said counterweight system is also provided.
