The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
The assembly tooling of a kind of wind-driven generator transmission main shaft of the present utility model and gear-box, comprise Primary Location mechanism and drag link mechanism, wherein, Primary Location mechanism is used for slinging and mobile transmission main shaft, make its axis consistent with gear-box axis level, and transmission main shaft is slightly inserted in the locking plate hole of gear-box; On the basis of above-mentioned Primary Location, drag link mechanism is mainly the design feature of having utilized the through wires hole in cabin and wheel hub communication cable and 400V power cable in transmission main shaft and gear-box, has realized the quick assembling of transmission main shaft and gear-box.
As shown in Fig. 1,2,6, drag link mechanism comprises pull bar 11, and an end of pull bar 11 is provided with apical ring 12, and the other end of pull bar 11 is helicitic texture 13, is combined with locking nut 14 on helicitic texture 13, on the pull bar 11 of locking nut 14 inboards also cover one protective sleeve 15 is arranged.Wherein, pull bar 11 is for the cable through wires hole on the quill shaft that passes transmission main shaft and gear-box, and apical ring 12 is used for overlapping with the transmission main shaft large end face, and protective sleeve 15 is used for contacting with the outer wall of gear-box; make the quill shaft 201 of gear-box be positioned at protective sleeve 15, protective sleeve 15 can be cup-like structure.
As shown in Fig. 3,4,5, in the above-described embodiments, Primary Location mechanism wherein comprises: two U-shaped shackles 21 and connected chain sling 22, suspender belt 31 and connected chain block 32; Wherein, U-shaped shackle 21 is used for being used in conjunction with the large end of transmission main shaft 100; Suspender belt 31 is used for being used in conjunction with the small end of transmission main shaft 100, and chain sling 22 and chain block 32 are controlled by driving respectively, and the axle center that chain block 32 also enough can be regulated transmission main shaft 100 is level.Above-mentioned Primary Location mechanism also can comprise a horizon rule 4, be used for being positioned over transmission main shaft 100, whether the axis that horizon rule 4 can detect transmission main shaft 100 and gear-box 200 level, and can adjust transmission main shafts 100 by above-mentioned chain block 32, and finally makes it axis horizontal.
Utilize above-mentioned frock to carry out the assembly method of wind-driven generator transmission main shaft and gear-box assembling as follows, coordinate and consult Fig. 1-6:
The gear-box 200 that (1) will arrive factory is unpacked, first adjust gear-box 200 and make its axis horizontal, recycle above-mentioned Primary Location mechanism, adjust transmission main shaft 100 and make its axis horizontal and consistent with the axis of gear-box 200, be specially: two U-shaped shackle 21 symmetries are arranged on the through hole of large end face of transmission main shaft 100, connect chain sling 22 in U-shaped shackle 21, chain sling 22 is arranged in a driving; Suspender belt 31 is bundled on the small end of transmission main shaft 100, connect chain block 32 on suspender belt 31, chain block 32 is arranged in another driving, then driving lifting simultaneously, again horizon rule 4 is placed on transmission main shaft 100, adjusts the position on the vertical direction of U-shaped shackle 21 and chain block 32 by the measurement result of horizon rule 4; When the axis of transmission main shaft 100 and gear-box 200 is adjusted into level, the driving of mobile U-shaped shackle 21 and chain block 32 simultaneously, make transmission main shaft 100 shift to gear-box 200, because the locking plate internal diameter of gear-box 200 is the conical surface, interior outer end of hole aperture is slightly larger than the Zhou Jing of transmission main shaft 100, therefore removable driving slightly is inserted in the locking plate hole of gear-box 200 transmission main shaft 100.
(2) pull bar 11 is penetrated from the cable through wires hole in the large end face of transmission main shaft 100; guarantee after penetrating that apical ring 12 overlaps with the large end face of transmission main shaft 100, the pull bar 11 that then passes at the cable through wires hole from gear-box 200 puts protective sleeve 15 and locking nut 14.
(3) bore area due to the locking plate of gear-box 200 is the conical surface, can be to slowly mobile U-shaped shackle 21 places driving and the chain block 32 places driving simultaneously of gear-box 200 sides, constantly tighten locking nut 14 with spanner simultaneously, carrying out along with this process, transmission main shaft 100 constantly is deep in the locking plate of gear-box 200 until to the position that requires (have structure location), then lock the clamping screw 202 of locking plate, and stamp on request corresponding moment, at this moment, the endoporus conical surface of locking plate will locking transmission main shaft 100, completes assembling process.
As shown in the partial view of Fig. 6; in whole assembling process; the protective sleeve 15 of drag link mechanism can contact with the outer wall of gear-box 200 always, and the power that produces in process can not be delivered to the quill shaft 201 of gear-box 200, so the quill shaft 201 of gear-box 200 can not use in the stress deformation impact.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment, the utility model is had been described in detail, for a person skilled in the art, it still can be modified to the technical scheme that previous embodiment is put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
