Description
Technical field
The invention belongs to a kind of generator assembling and maintenance tool.
Background technology
The electricity generating principle of rare earth permanent-magnetic generator is directly to connect the rotor that has permanent magnet by engine in stator, to rotate, and produces alternating magnetic field.Make stator induce alternating current thus.Because stator is to be built up by silicon steel sheet, be a magnetic conductor, if when it is shifted to rotor, just can feel at once one powerful attraction with its suction to rotor.So install rare-earth permanent-magnet electric machine, the effective tool of a cover ability controlling magnetic field intensity must be arranged.This instrument can be controlled the magnetic field intensity of rotor, and can be accurately stator be installed to and wants its this place of going.
But if use general tool, to installation, replacing, maintenance and time-based maintenance work (periodic maintenance of motor internal: like the cleaning of inner rubbish, the observation of the state of insulation etc.) inconvenience of stator and rotor, the precision that stator and rotor are installed also is difficult for guaranteeing.
Summary of the invention
The present invention provides the special use of a kind of dismounting rare earth permanent-magnetic generator stator to draw horse, its objective is to solve the shortcoming that prior art exists, and can make the work to installation, replacing, maintenance and the time-based maintenance of rare earth permanent-magnetic generator stator and rotor bring convenience; Improve the precision of installing when joining stator and rotor.
The technical solution adopted for the present invention to solve the technical problems is:
Horse is drawn in the special use of a kind of dismounting rare earth permanent-magnetic generator stator, it is characterized in that: have one and be provided with externally threaded screw rod, screw rod one end is installed with handwheel, and the other end of screw rod is installed with cushion block; One end of adapter sleeve is the outwardly directed horse positioning sleeve that draws, and draws horse positioning sleeve end to have interior hexagonal, and the other end of adapter sleeve is a shrinkage pool, the ccontaining thrust bearing in shrinkage pool bottom, and above-mentioned cushion block inserts in the shrinkage pool and the top is against on the thrust bearing; Spiral shell is provided with thread bush on the screw rod, is installed with on the thread bush to draw the melphalan dish; Draw and be installed with several pull bars on the melphalan dish, pull bar and pull bar parallel with screw rod is around the screw rod circumference uniform distribution; The same number of circular arc anchor ear of number and pull bar is around the screw rod circumference uniform distribution, and the end of anchor ear lays respectively at the both sides of corresponding pull bar with the end of adjacent anchor ear, and has bolt above-mentioned two anchor ear ends are connected with pull bar.
The external screw thread of said screw rod is a trapezoidal thread.
The usefulness of technique scheme is:
The present invention is simple in structure, and the positioning sleeve that cooperatively interacts with generator is arranged, and can improve the precision of installing when joining stator and rotor, and the fail safe during work is good, and instrument is easy, and is easy to operate, laborsaving again.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is an axial view of the present invention;
Fig. 2 is A-A, the B-B flattening figure of Fig. 1.
Embodiment
Like Fig. 1, shown in Figure 2:
The present invention is that horse is drawn in the special use of a kind of dismounting rare earth permanent-magnetic generator stator, and it has one and is provided with trapezoidal externally threaded screw rod 4, and screw rod 4 one ends are installed with handwheel 1 with the structure of nut 2, key 4, and the other end of screw rod 4 is installed with cushion block 13.
Has an adapter sleeve 14; Outwardly directed the draw horse positioning sleeve 17 of one end of adapter sleeve 14 for being connected with bolt 16; Draw horse positioning sleeve 17 ends to have interior hexagonal 171; The other end of adapter sleeve 14 is a shrinkage pool 141, the ccontaining thrust bearings 15 in shrinkage pool 141 bottoms (can select thrust ball bearing), and above-mentioned cushion block 13 inserts in the shrinkage pool 141 and the top is against on the thrust bearing 15.
Spiral shell is provided with the thread bush 7 with trapezoidal internal thread on the screw rod 10, is installed with bolt 8 and nut 9 on the thread bush 7 and draws melphalan dish 6; Draw and be installed with 3 pull bars 5 on the melphalan dish 6, the parallel and pull bar 5 of pull bar 5 and screw rod 10 is around screw rod 10 circumference uniform distributions; 3 circular arc anchor ears 11 are around screw rod 10 circumference uniform distributions; The end 111 of each anchor ear 11 lays respectively at the both sides of corresponding pull bar 5 with the respective end 111 of adjacent anchor ear 11, and has bolt 12 (can select the bolt of M10X70 specification) end 111 of above-mentioned two anchor ears 11 is connected with pull bar 5.
Concrete operation method:
1, dismounting stator:
1. earlier the stator rear end cap is removed, opened generator and expose rotor, rotor clamping screw, stator
2. the interior hexagonal 171 of positioning sleeve 17 is inserted on the outer-hexagonal of rotor and generator amature clamping screw.
3. in adapter sleeve 14, put into thrust bearing 15.Be adjusted to the appropriate location to screw rod 10; Promptly be pressed in cushion block 13 on the thrust bearing 15; For example draw the bottom surface 61 of horse owner's ring flange 6 to be placed on to be advisable that (concrete size is set according to generator size from stator front end housing 30mm place; Relate to the size part below in like manner), at this moment the assembly of pull bar 5, anchor ear 11 stretches into interior stator of generator and the space between the rotor, is enclosed in outside the stator.
4. lock the bolt 12 of three M10X70 on the anchor ear 11.At this moment anchor ear 11 is held stator tightly.
5. with handwheel 1 to right rotation, this moment thread bush 6 the trapezoidal external screw thread interaction of trapezoidal internal thread and screw rod, anchor ear 11, pull bar 5, draw the combining structure of horse owner's ring flange 6 to embrace stator and stator is upwards extracted at leisure, promptly leave the front end housing of stator.
6. when stator pulls out the top of adapter sleeve 14, just can positioning sleeve 17 be extracted out the outer-hexagonal of the hanging bolt that rotors are connected with generator, thereby with stator with drawing horse to take down from rotor top.
2, set son:
1. positioning sleeve 17 is inserted on the outer-hexagonal of the hanging bolt that rotors are connected with generator.
