| 摘要 |
The present invention relates to a wind turbine driving shaft for transmitting power of a rotor shaft (10) to an input shaft (25) of a gearbox (20), which comprises: a connection means (30) connecting the rotor shaft (10) and the input shaft (25) onto each flange by using a plurality of bolts; and a buffer means (40) having a buffer material (41) concentrically surrounding each of the bolts. Therefore, the present invention can promote an improvement of an actual lifetime due to the reduction of a non-torque load transmitted to the gearbox by absorbing a torque load transmitted from the rotor shaft of a wind turbine and an axial force and a bending moment. |
