Jigger positioning device of large direct-drive wind-power permanent magnet power generation set

Abstract

The invention discloses a jigger positioning device of a large direct-drive wind-power permanent magnet power generation set, comprising a stationary shaft, a movable shaft and a locking pin, wherein a front bearing is arranged between the stationary shaft and the movable shaft; the front side of the front bearing is provided with an annular front bearing end cover connected to the stationary shaft, the front end face of the movable shaft and the front bearing end cover are provided with pin holes which can be simultaneously penetrated by the locking pin. The jigger positioning device furthercomprises a jigger fixing frame connected to the movable shaft, a jigger bearing arranged on the jigger fixing frame, and a jigger gear shaft, wherein a handle is connected to one end of the jigger gear shaft, the jigger bearing penetrates through the middle part of the jigger gear shaft, and a jigger gear is connected to the other end of the jigger gear shaft; the inner circumference of the front bearing end cover is provided with teeth meshed with the jigger gear. The jigger positioning device of the large direct-drive wind-power permanent magnet power generation set has the beneficial effects that: the movable shaft can be conveniently aligned to the pin hole on the front bearing end cover so that the locking pin can be inserted in the pin hole conveniently to lock the brake of the power generator; therefore, the jigger positioning device is time-saving, labor-saving, convenient to operate, rational in structure and safe in use.

Description

technical field [0001] The invention relates to a barring positioning device for a large-scale direct-drive wind-force permanent magnet generator set. Background technique [0002] At present, when the existing direct-drive wind permanent magnet generator sets require maintenance personnel to enter the hub of the wind rotor for maintenance operations, the generator needs to be feathered and then locked with a locking pin to prevent accidents such as casualties caused by the rotation of the wind rotor. occur. [0003] In the process of locking, it is necessary to align the locking pin with the pin hole. Due to the change of wind direction or the inertia of the wind wheel itself, the wind wheel of the generator will always rotate slightly, or even if the wind wheel is stopped Rotation, the locking hole is also difficult to be in the desired position, especially for large-scale direct-drive wind permanent magnet generators, it is even more difficult; and because the permanent...

[0003] In the process of locking, it is necessary to align the locking pin with the pin hole. Due to the change of wind direction or the inertia of the wind wheel itself, the wind wheel of the generator will always rotate slightly, or even if the wind wheel is stopped Rotation, the locking hole is also difficult to be in the desired position, especially for large-scale direct-drive wind permanent magnet generators, it is even more difficult; and because the permanent magnet generator itself has the electromagnetic force of the stator and rotor, these All of these have resulted in difficulties in alignment of wind turbine gears, making the positioning of gears time-consuming and labor-intensive
