| 摘要 |
The present invention relates to a wind turbine, which comprises a rotatable structure being coupled to a hub of the wind turbine and to a generator rotor comprising a brake disc (101), a stationary structure being coupled to a generator stator and comprising a stator frame (102) and a safety bearing element (104, 104', 104"). The rotatable structure is rotatably coupled to the stationary structure, wherein the stator frame (102) comprises a brake mounting section (103, 103', 103") to which a calliper brake (105, 105', 105") is mountable such that the brake disc (101) is breakable by the mounted calliper brake (105, 105', 105"). The safety bearing element (104, 104', 104") is mounted to the brake mounting section (103, 103', 103") such that the brake disc (101) is in slidable contact with the safety bearing element (104, 104', 104") if a distance between the brake mounting section (103, 103', 103") and the brake disc (101) is reduced below a predetermined reference value. |
