| 摘要 |
The invention concerns a wind turbine comprising a housing (7), a main bearing (12), a rotor rotatable around a more or less horizontal axis comprising vanes mounted in a hub (15), which hub (15) is accessible through the main bearing (12), and a generator whereby the main bearing has a first ring (28,31) which is at a first side coupled to the housing (7) and a second ring (23) connected to the hub (15) and to rotating parts (11) of the generator and between the first ring (28,31) and the second ring (23) one or more rows of rotating elements (26) which can roll between at least two tracks on the first ring and two tracks on the second ring. In the wind turbine according to the invention a first stiffener (17) is coupled to a second side of the first ring for additional support of the tracks of the first ring. |
