Abstract: Wind power station, which includes a vertical tower (1), a rotor that includes a hub part (18) and blades (16) that is fitted to the top end of the tower and that is aligned into the wind and rotated by the wind, a rotor shaft (11), which transmits rotating motion to a generator (12, 13, 14) connected to the aforementioned shaft in a direct-drive power station and to a gear box in a geared power station, and also a revolving frame (10) that is fitted to the top end of the tower (1) on bearings so as to rotate around the vertical axis (17), in which frame the rotor shaft (11) is also mounted on bearings.
Abstract: Adjustment system for the pitch angle of a wind turbine, which wind turbine includes an axis of rotation that is horizontal or at a small angle with respect to the horizontal plane, and a rotating hub to which the blades are connected in a manner allowing their slewing, in which system an adjustment arrangement is arranged inside the hub and/or shaft. The arrangement includes a drive device moving in the direction of the axis of rotation as well as an adjustment cylinder apparatus or corresponding for moving it. Rod-shaped control parts for each blade are connected in a hinged manner to the drive device. The control parts are connected to the butt part of each blade such that the pitch angle can be adjusted by shifting the drive device.
