The main shaft and the gear box in the prior art are rigidly connected (for example, a rigid connection mode of a locking disc or a flange disc is adopted), and the torsion arm of the gear box adopts an elastic support structure form. However, the rigid connection can not absorb the impact load of the wind wheel, and the impact load is transmitted into the gear box, so that the service life of the gear and the bearing is influenced.
Therefore, there is a need to provide a structure form in which the input end is flexibly connected through the elastic coupling and the torsion arm is rigidly connected, so as to solve the adverse effect of the impact load on the gearbox.
Disclosure of Invention
The utility model discloses an offshore wind power gear box connection structure realizes input flexonics, avoids the impact load of wind wheel to the gear box.
The utility model discloses an offshore wind power gear box connecting structure, which comprises an input end shaft coupling, a connecting flange, an output end planet carrier and a gear box;
one end of the connecting flange and the inner ring of the input end coupler form a whole and are connected with the outer ring of the input end coupler through an elastic body; the other end of the connecting flange is provided with a hole and is fixedly connected with the output end planet carrier through a bolt; the output end planet carrier is arranged in the gear box.
Furthermore, the bolt is radially sleeved with a connecting pin and is connected with the output end planet carrier through a compression connecting pin.
Furthermore, holes are arranged in the circumferential direction of the other end of the connecting flange and are fixedly connected with the output end planet carrier through bolts.
Further, a torsion arm is fixedly arranged outside the gear box, and the torsion arm is used for being rigidly connected to the frame through bolts.
The utility model discloses beneficial technological effect does:
1) the connecting pin transmits torque, and the bolt transmits axial force to play a role in pressing;
