    • 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. For mounting the revolving frame (10) on bearings onto the top part of the tower, the top part of the tower (1) includes 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.
    • 包括垂直塔(1)的风力发电站,包括轮毂部分(18)和叶片(16)的转子,所述转子安装在塔顶部并且被排列成风并由风旋转 ,转子轴(11),其将旋转运动传递到在直接驱动发电站中连接到上述轴的发电机(12,13,14)和齿轮箱中的齿轮箱,以及旋转框架 (10),其在轴承上安装在塔架(1)的顶端上,以围绕垂直轴线(17)旋转,转子轴(11)的框架也安装在轴承上。 为了将旋转框架(10)安装在轴承上的塔架顶部上,塔架(1)的顶部包括第一轴承(5)或(20),其主要至少承受来自旋转的 框架(10)以及与上述轴承设置成距离H的第二轴承(9)或(19),在这种情况下,一个轴承(9),(19)主要承受来自 在这种情况下,上述轴承(9),(19,20)中的上一个的支撑件通过离开塔架的支撑件布置并装配在旋转框架内。
