The lower end of rotor 1, the second cone block is fixed on lead 13, is offered on installing plate 4 and the rotor mounting location inside stator 2
The through hole aligned, lead 13 passes through through hole, and adjusting means 5 is arranged on support body and positioned at the lower section of installing plate 4, for adjusting
The gradient of lead 13, regulating block 10 is threadedly coupled with threaded rod 11, and regulating block 10 is contacted with the side wall of lead 13, screw thread
Bar 11 is threadedly coupled with support body.
In use, the stator 2 of motor, inside has been inserted into shaping winding, stator 2 is fixed on installing plate 4, then by
One cone block is fixed on the rotating shaft end face of one end of the rotor 1 of motor, and rotor 1 is put into the rotor inside stator 2 from the top down
Installation site, now, the conical surface on the first cone block are docked with the conical surface on the second cone block, for example, the conical surface on the first cone block is
The conical surface on male cone (strobilus masculinus), the second cone block is inner conical surface so that rotor attaches together firm centering, meanwhile, threaded rod 11 is turned, is adjusted
Block 10 can promote lead 13 to be tilted to any direction, tilted so as to adjust rotor 1 to any direction, overcome attraction, solution
Rotor of having determined attaches together firm centering, reduces the attracting assembly problem of rotor.
In order to further optimize such scheme, the other end of rotor 1 and the end cap 8 of motor are connected by securing device 7,
During installation, due to rotor 1 the other end upward, the referred to as upper end of rotor 1, end cap 8 is referred to as the upper end cover of motor, securing device 7
Including first body of rod and second body of rod set in right-angled intersection, the two ends of first body of rod and second body of rod are each attached to end cap 8
On, the cross part of first body of rod and second body of rod is fixedly connected by bolt with the other end of rotor 1.When mounted, motor
Upper end cover, its quality is uneven in circle distribution, it is necessary to be sling rotor 1 and upper end cover together with overhead traveling crane after rotor 1 is transferred to
When, rotor 1 can not be vertical, and rotor is attached together and brings difficulty, therefore, and using the securing device 7, its structure is handed over for basin saltire
Structure is pitched, the upper end of rotor 1 and the relative securement of upper end cover is realized.Just securing device 7 is fixed after upper end cover loads rotor 1
