摘要： Wind power station, which comprises a vertical tower (1), the rotor of the power station fitted to the top end of the tower and aligned towards the wind, which rotor comprises blades and also a hub part that supports the aforementioned rotor, which hub part comprises a hub frame (4) that revolves around an essentially vertical axis resting on bearings (5, 6), as well as the necessary components connected to the aforementioned hub frame (4), such as a rotating shaft for the aforementioned rotor blades, bearings for the aforementioned rotating shaft, a possible generator arrangement, and also a rotator arrangement of the hub frame (4), by means of which the rotor is aligned towards the wind. The rotator arrangement of the hub frame (4) comprises a brake disc/flange ring (8) fixed either to a non-rotating tower (1) or to an extension (2) of it, or alternatively to a revolving hub frame (4), onto the surface of which brake disc/flange ring a number of gripping means (13) are arranged to press and to move to new positions on the surface of it such that by means of movable rods, such as hydraulically lengthening or shortening cylinders (11), leaving the aforementioned gripping means (13) a rotary motion can be achieved between the aforementioned flange ring (8) and the frame part (4) or (1, 2) of it, to which the second ends of the movable rods are fixed.

摘要： Wind power station, which comprises a vertical tower (1), a rotor that comprises 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. For mounting the revolving frame (10) on bearings onto the top part of the tower, the top part of the tower (1) comprises a first bearing (5) or (20) that mainly bears at least the vertical load coming from the revolving frame (10), as well as a second bearing (9) or (19) disposed at a distance H from the aforementioned bearing, in which case one of the bearings (9), (19) bears mainly the radial load coming from the revolving frame and in which case the support of the upper one of the aforementioned bearings (9), (19, 20) is arranged by means of a support piece leaving the tower and fitted inside the revolving frame.
