Problems solved by technology

In the prior art, the rotor and the hub are directly rigidly connected through the connecting flange, so the bending moment and deformation of the impeller will be transmitted to the generator, resulting in the failure to maintain the air gap of the generator. In severe cases, it will cause the generator to fail Suction between stator and rotor
At the same time, large bending moments can also cause damage to generator components (such as bearings)

Abstract

The invention provides a wind generator set. The wind generator set comprises a hub rotationally installed on a supporting frame, a wind generator comprising a rotor and a stator, an adjustable connection piece connecting the hub with the rotor, wherein the stator is fixed to the supporting frame, the adjustable connection piece is arranged to enable the hub to drive the rotor to rotate along withthe hub, and the hub is allowed to incline downwards relative to the rotor. According to the wind generator set, the torque of the hub can be transmitted to the rotor, and the situation that the bending moment of the hub is transmitted to the rotor is basically avoided.

Description

technical field [0001] The present invention relates to the technical field of wind power generation, and more specifically, to a wind power generating set. Background technique [0002] Wind turbines are used to convert wind energy into electrical energy. A wind turbine consists of a hub on which the blades are mounted, a generator, and a tower supporting the hub and generator. [0003] The hub is connected to the rotor of the generator to transmit the torque of the impeller (blades and hub) to the rotor of the generator. In the prior art, the rotor and the hub are directly rigidly connected through the connecting flange, so the bending moment and deformation of the impeller will be transmitted to the generator, resulting in the failure to maintain the air gap of the generator. In severe cases, it will cause the generator to fail Suction between stator and rotor. At the same time, a large bending moment will also cause damage to components of the generator (eg, bearings)...
