Automatic centering adjustment device and centering method used between gearbox and generator

Abstract

The invention provides an automatic centering control device used between a speed increasing box and a power generator. The automatic centering control device used between the speed increasing box and the power generator comprises three grating sensors, a laser emission device, a plurality of hydraulic pressure leveling supports, a hydraulic station and a main controller, wherein the three grating sensors are mounted on the speed increasing box and are in communication connection with the main controller; the distances between grating sensors and an output shaft are the same; the laser emission device is fixedly connected with the input shaft of the power generator; the plurality of hydraulic pressure leveling supports are connected with the hydraulic station and are supported at the bottom of the power generator; the hydraulic station is in communication connection with the main controller. The automatic centering control device and the centering method thereof, provided by the invention, are simple in structure; through regulating the heights of the hydraulic pressure leveling supports in real time, the centering is conducted; the automatic centering control device and the centering method thereof ensures that the coaxiality of the speed increasing box and the coaxiality of the power generator are in an ideal range; therefore, the normal operation of the speed increasing box and the normal operation of the power generator are ensured; the speed increasing box and the power generator are prevented from damages caused by the decline of the coaxiality.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to an automatic centering adjustment device and a centering method used between a gearbox and a generator. Background technique [0002] As a clean and renewable energy, wind energy is sought after by countries all over the world. While the wind power industry is developing vigorously, the safety of wind turbines is getting more and more attention. Frequent damage to the gearbox and generator has brought great losses to the owner. Once the gearbox or generator is damaged , Maintenance will consume a lot of manpower and material resources. The main reason for the damage of the gearbox and the generator is that the shafts of the two are not aligned. The elastic support used by the generator of the wind turbine is generally a rubber product.

While the wind power industry is developing vigorously, the safety of wind turbines is getting more and more attention. Frequent damage to the gearbox and generator has brought great losses to the owner. Once the gearbox or generator is damaged , maintenance will consume a lot of manpower and material resources

The main reason for the damage of the gearbox and the generator is that the shafts of the two are not aligned. The elastic support used by the generator of the wind turbine is generally a rubber product. With the increase of the service life, the elastic support gradually becomes aging and invalid, making The centering performance between the gearbox and the generator drops sharply, resulting in additional load and vibration during the operation of the gearbox and the generator, resulting in damage to the gearbox and the generator, and frequent manual alignment adjustments The maintenance cost is too high and it is very difficult to implement
