[0002] In a wind turbine, the impeller converts wind energy into rotational mechanical energy and transmits it to the gearbox through the main shaft. After the gearbox increases the speed, the mechanical energy is transmitted to the generator through the coupling and converted into electrical energy output. Among them, the high-speed shaft of the gearbox and the drive shaft of the generator are connected through a coupling, but the two must maintain a high degree of coaxiality to ensure the safe and stable operation of the wind turbine. Therefore, whether it is when the wind turbine equipment is installed or during regular maintenance after the equipment is put into operation, the generator needs to be aligned.
