Description
Technical field
The utility model relates to a kind of jiggering positioning device of large-scale directly-driven wind permanent magnet generator unit.
Background technique
At present, existing directly-driven wind permanent magnet generator unit enters when carrying out maintenance operation in the wind wheel wheel hub the personnel of needing repairing, and need shut down the back with the stop pin locking, to prevent the generation of accidents such as the wind wheel rotation causes casualties by the generator feathering.
In the process that locks, need be with spring bolt and pin-and-hole contraposition, the generator wind wheel since wind direction changes or wind wheel existence itself inertia, always there is fine rotation in the generator wind wheel, even perhaps allow wind wheel stop operating, its locking aperture also is difficult to just on the desired position, especially concerning large-scale directly-driven wind permanent magnet generator unit, and difficulty more just; And because there is the electromagnetic force of stator and rotor in permanent magnet generator itself, these have all caused wind-driven generator jiggering contraposition difficulty, make the jiggering location not only time-consuming but also require great effort.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of jiggering positioning device of large-scale directly-driven wind permanent magnet generator unit time saving and energy saving, easy to operate, rational in infrastructure, safe in utilization.
The utility model is realized by following measure:
The jiggering positioning device of a kind of large-scale directly-driven wind permanent magnet generator unit of the present utility model, comprise dead axle, moving axis and spring bolt, be provided with fore bearing between described moving axis and the dead axle, the fore bearing front side is provided with the annular fore bearing end cap that is connected on the dead axle, the front-end face of moving axis and fore bearing end cap are provided with the pin-and-hole that spring bolt can pass simultaneously, also comprise:
The jiggering fixing frame is connected on the moving axis;
The jiggering bearing is arranged on the jiggering fixing frame; And
The jiggering gear shaft, an end is connected with handle, and the jiggering bearing is run through in the centre, and the other end is connected with the jiggering gear;
Described fore bearing end cap inner circumference is provided with the tooth that is meshed with the jiggering gear.
Preferably, above-mentioned jiggering fixing frame is a long strip, is connected on the front-end face of moving axis.
Preferably, be provided with the jiggering bearing support in the middle of the above-mentioned jiggering fixing frame, the jiggering bearing is arranged on the jiggering bearing
In the seat.
The beneficial effects of the utility model are:
When needs brake to generator, operator hand handle rolling disc skiving wheel shaft, just can too big strength drive the moving axis rotation, and easily moving axis be located, prevent that wind wheel is owing to waving that factors such as inertia cause, be convenient to the alignment of the pin-and-hole on moving axis and the fore bearing end cap so just can be inserted pin-and-hole with spring bolt easily, finish brake locking generator, time saving and energy saving, simple to operate, rational in infrastructure, safe in utilization.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
A-A cross-sectional view among Fig. 2 the utility model Fig. 1.
Fig. 3 is the structural representation of fore bearing end cap.
Among the figure: 1 wheel hub, 2 moving axis, 3 casings, 4 rotors, 5 dead axles, 6 jiggering gears, 7 fore bearings, 8 fore bearing end caps, 9 spring bolts, 10 jiggering gear shafts, 11 jiggering bearings, 12 handles, 13 jiggering fixing frames, 14 pin-and-holes, 15 teeth.
Embodiment
Now be described further with accompanying drawing in conjunction with the embodiments:
As shown in Figure 1, 2, 3, the jiggering positioning device of a kind of large-scale directly-driven wind permanent magnet generator unit of the present utility model, comprise dead axle 5, moving axis 2 and spring bolt 9, dead axle 5 is fixed on the casing 3 motionless, moving axis 2 front ends connect wheel hub 1 and drive rotor 4 rotations, be provided with at least two bearings between moving axis 2 and the dead axle 5, near the fore bearing 7 of wheel hub 1 with away from the rear bearing of wheel hub, moving axis 2 is enclosed within on fore bearing 7 and the rear bearing and rotates.Fore bearing 7 front sides are provided with the annular fore bearing end cap 8 that is connected on the dead axle 5.The front-end face of moving axis 2 and fore bearing end cap 8 are provided with pin-and-hole 14, and after both pin-and-hole 14 alignment, spring bolt 9 passes and is inserted into behind the pin-and-hole 14 on the moving axis front-end face on the fore bearing end cap in the pin-and-hole 14, thereby with Generator brake.
Connect jiggering fixing frame 13 on the moving axis 2, preferred, adopt long strip jiggering fixing frame 13, will coil
Working principle is:
When the direct wind-driven generator group need be safeguarded or keep in repair, need generator is locked, operator climb active handle 12 with hand after entering in the wheel hub, because the tooth on jiggering gear 6 and the fore bearing end cap 8 is meshing with each other, handle 12 rotating band Moving plate skiving wheel shafts 10 rotate in jiggering bearing 11, and then drive jiggering gear 6 inner circumferences along fore bearing end cap 8 and move, because fore bearing end cap 8 is fixed statics, thereby force moving axis 2 rotations that are connected with jiggering fixing frame 13.When the pin-and-hole 14 on the moving axis 2 of generator when pin-and-hole 14 on the fore bearing end cap 8 aligns, operator's handle 12 that stops operating is inserted into spring bolt 9 in two aligned pin 14, thereby generator is locked, maintains easily personnel's work.
The foregoing description is described to be in order to specify this patent; though describe by specific term in the literary composition; but can not limit the protection domain of this patent with this; being familiar with the personage of this technical field can be after the spirit of understanding this patent and principle change or revises it and reach equivalent purpose; and this equivalence change and modification all should be covered by the claim scope and define in the category.
