Patent ID: 7470111

Claim:
A wind turbine equipped with a tower, a nacelle rotatably mounted on the tower, a rotor rotatable at the nacelle about a rotor axis of rotation and comprising one rotor hub and at least one rotor blade which is coupled by a blade bearing to the rotor hub while rotatable about a blade adjustment axis, the blade bearing comprising an inner ring firmly affixed to the rotor hub and an outer ring having toothing and that is firmly connected to the rotor blade, the rotor blade being rotatable by a blade adjustment drive comprising a drive motor actuating a drive pinion meshing with the outer toothing of the outer ring, wherein, on the rotor hub's side away from the nacelle, the drive pinion is configured at an angle of 10 to 30° as measured about a blade adjustment axis toward a plane subtended by the rotor axis of rotation and the blade adjustment axis, and wherein the drive motor is mounted at a distance from the rotor axis of rotation that is smaller than a distance between the drive pinion and the rotor axis of rotation.
