It is easy to use, the labor intensity of staff can be reduced, the wind turbine gearbox O&M improved efficiency is with tearing bearing outer ring device open.
The object of the present invention is achieved by the following technical solutions, a kind of wind turbine gearbox high speed shaft bearing outer ring
Provision for disengagement, it is mainly by pivot flange, steel ball, holding screw, pull rod, sleeve, plain washer, spring washer, support rod, nut
And beam slab forms, and steel ball is placed in the supporting methods flange aperture, and be cooperatively connected with the support rod, is passed through with holding screw
Pivot flange aperture simultaneously screws in the annular groove of support rod, and support rod passes through the hole of beam slab, and spiral shell is screwed in after installing spring washer
It is female；The sleeve is inserted in two pull rods；After two pull rods are each passed through the slot on beam slab both sides, successively screwed in respectively from end
Plain washer, spring washer, nut.
As preferred: the support rod lower end is provided with annular groove, and the aperture that holding screw passes through pivot flange is inserted into institute
In the annular groove stated, support boom end is provided with groove, hole is provided with inside pivot flange, bottom hole is groove, and steel ball is placed on supporting methods
After blue groove, it is coupled with support rod, steel ball is located between pivot flange and support rod.
It is provided on the beam slab convenient for penetrating first slot and the second slot of two pull rods；The sleeve set
In the outside of two pull rods.
As preferred: a cephalic par of the pull rod is transported persons or goods by cart, and the shape transported persons or goods by cart is polygon or sector, another head end
It cuts for adjusting direction of transporting persons or goods by cart, convenient for being confirmed whether the homalocephalus being adjusted in place in portion.
The present invention first passes through the homalocephalus of two pull rods of rotation when in use, and homalocephalus is in horizontal positioned, makes two of pull rod
Foot is inside, forms face-to-face form, in this way in beginning mounting device to the bearing for needing to dismantle, after passing through bearing from inside, then
The homalocephalus 180 degree of rotating rod, keeps the foot of two pull rods outside, forms back-to-back form, after the foot of pull rod catches on bearing, rotation
The nut of support rod makes pull rod foot that bearing be pulled to move together, to complete the dismantlement work of bearing.It is realized by this device
The dismounting work that high speed shaft cylindrical bearing outer ring is completed in fan engine room, meets O&M demand, reduces O&M cost, solves wind
A great problem in machine maintenance work.This device also can be applied to the work of other industry disassembly NU bearing outer ring.
The present invention repairs the suitable tooling of spatial design of dismounting high speed axle bearing according to gear-box, realizes to wind power gear
The dismounting of case high speed axis cylindrical bearing outer ring has structure simple, and expense is low, easy for operation, can reduce staff's
Labor intensity, the features such as improving efficiency.
Detailed description of the invention
Fig. 1 is provision for disengagement perspective view of the invention.
Fig. 2 is provision for disengagement fragmentary cross-sectional view of the invention.
