Abstract
The present invention relates to wind turbines with variable rotor blades whose pitch angles are adjustable. An adjustment unit is provided for adjusting the pitch angle of the rotor blades with a pivot bearing comprising at least two coaxial bearing rings that are rotatable against each other, at least one adjustment actuator for rotating the two bearing rings, and a supply unit for supplying the adjustment actuator with energy, whereby the adjustment actuator and the supply unit are disposed on opposite sides on a plate-shaped adjustment drive carrier part which is rotatably connected with one of the bearing rings and comprises a rotatable support bearing for the support of the adjustment actuator. A least one part of the supply unit is rotatably mounted on the carrier part such that the supply unit or its rotatably mounted part and the adjustment actuator are jointly rotatably mounted and/or swivel-mounted on the carrier part.
