Abstract
The utility model relates to a kind of rotor thrustor, comprise worm gear case, the worm-and-wheel gear be located in worm gear case, pushing tow screw mandrel, pushing tow screw mandrel supporting seat and the reductor that is connected with worm-drive, worm-and-wheel gear is made up of worm gear and nut and worm screw, and worm gear and nut and pushing tow wire rod thread connect and compose screw pair.When the utility model uses, worm gear case is fixed on the fixed support of erecting yard, the reductor energising of translator rotates, drive the worm screw in worm gear case, drive worm gear and nut rotates, the rotation of worm gear and nut makes pushing tow leading screw move linearly, and pushing tow screw mandrel is fixedly connected with by bearing pin with generator amature, can realize the rectilinear movement of pushing tow rotor.The utility model structure is simple and can realize accurately locating in installation process.
Description
Technical field
The present invention relates to large-scale generator rotor mounting technique field, be specifically related to a kind of rotor thrustor.Be specially adapted to the assembling of exceeding length, major diameter generator amature.
Background technology
In large-scale generator rotor assembling, traditional method is jack draw-gear, and steel wire rope colligation is fixed on rotor, coordinates sliding machine, pulls rotor, slide into precalculated position by jack traction.
This apparatus structure is more complicated, and is difficult to accurate location.
Summary of the invention
A kind of structure that the purpose of this utility model is to provide is comparatively simple and can realize the rotor thrustor of accurately locating in installation process.
The utility model solves the technical scheme that its technical problem adopts: a kind of rotor thrustor, comprise worm gear case, the worm-and-wheel gear be located in worm gear case, pushing tow screw mandrel, pushing tow screw mandrel supporting seat and the reductor that is connected with worm-drive, worm-and-wheel gear is made up of worm gear and nut and worm screw, and worm gear and nut and pushing tow wire rod thread connect and compose screw pair.
Be provided with rolling bearing in the utility model worm gear case, worm gear and nut is connected with worm gear case by rolling bearing.
Above-mentioned worm gear case also can be provided with pushing tow screw mandrel protective cover.
When the utility model uses, worm gear case is fixed on the fixed support of erecting yard, the reductor energising of translator rotates, and drives the worm screw in worm gear case, drives worm gear and nut to rotate, the rotation of worm gear and nut makes pushing tow leading screw move linearly, pushing tow screw mandrel is fixedly connected with by bearing pin with generator amature, and because large-scale generator rotor has larger quality, pushing tow screw mandrel can not rotate, drive the rectilinear movement of pushing tow leading screw during nut rotation, the rectilinear movement of pushing tow rotor can be realized.The utility model structure is simple and can realize accurately locating in installation process.
The utility model also has the following advantages:
1, translator reductor is selected;
2, worm gear and nut combinations are integrated, and are worm gear and nut;
3, by reductor, worm screw, worm gear double reduction, nut low speed rotation can be realized, ensure that nut, screw mandrel are stable, pushing tow at a slow speed;
4, can adopt overlength screw mandrel, aiding support seat, stroke is long.
5, pushing tow uses screw rod, nut screw mechanism, can realize axial self-locking.
Embodiment
Fig. 1 is shaft side figure of the present utility model.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the left view of Fig. 2.
Embodiment
Feature of the present invention and correlated characteristic thereof are further described, so that the understanding of technical staff of the same trade by example below in conjunction with accompanying drawing:
See Fig. 1-Fig. 3, the utility model comprises worm gear case 1, be located at worm-and-wheel gear in worm gear case 16,9, pushing tow screw mandrel 2, pushing tow screw mandrel supporting seat 3 and the reductor 4 that is connected with worm-drive, worm-and-wheel gear is made up of worm screw 9 and worm gear and nut 6, and worm gear and nut 6 and pushing tow screw mandrel 2 are threaded formation screw pair.
Be provided with rolling bearing 8 in the utility model worm gear case 1, worm gear and nut 6 is connected with worm gear case 1 by rolling bearing 8.
Above-mentioned worm gear case 1 also can be provided with pushing tow screw mandrel protective cover 7.
The utility model worm gear case 1 is connected on the fixed support of erecting yard, fixes with bolt.Pushing tow leading screw 2 head and generator amature bearing pin 5 are connected and fixed.Adjustment supporting base 3, ensure that pushing tow screw mandrel is smooth by supporting base 3, pushing tow screw mandrel 2 keeps straight line, does not bend.The reductor 4 of translator is energized and rotates, drive the worm screw 9 in worm gear case 1, worm gear and nut 6 is driven to rotate, because large-scale generator rotor has larger quality, pushing tow screw mandrel can not rotate, the rotation of worm gear and nut 6 makes pushing tow leading screw 1 move linearly, and rotate forward pushing generator rotor and advance, reversion can retreat.When stopping operating, nut, screw mandrel can realize self-locking, and generator amature can stablize hold mode.
