| 摘要 |
The invention relates to a directly actuated power train for a wind turbine which includes a wind rotor (15), including a rotor hub (17) and at least one blade (18), a permanent-magnet generator (41) directly actuated by means of a generator shaft (43) rigidly connected to the main shaft (29), the wind rotor (15) and the generator (41) being located on opposite sides relative to the tower (11), the generator being supported (41) by the generator shaft (43) by means of a bearing unit; the rotor hub (17) being supported by the supporting structure (13) of the wind turbine by means of a main bearing (27) that does not allow the transmission of bending moments; the connections between the main bearing (27), the main shaft (29) and the generator shaft (43) being suitable for transmitting the torque of the wind rotor to the generator shaft (43) without any bending movements. |
