Dynamic seat (5), descending jack, so that rotor bearing seat (2) is placed on the mounting seat (3), and the company of being bolted
It connects, the operating process for wearing rotor can be completed, subsequent installation process can be carried out.
10. utilizing the operating method of the auxiliary device for wearing rotor for generator according to any one of claims 8, it is characterised in that: first
First, a lifting asessory shaft is fixedly mounted in the front end of rotor；
Then, driving is fixedly connected with two suspension centres of rotor by suspender belt, rotor is sling by driving, slowly to stator
(16) direction is mobile, and to lift asessory shaft and pass through stator (16), until the front end of the lifting asessory shaft is from stator (16)
Front end be pierced by, rotor is located at the inlet of stator (16) rear end at this time, and does not pierce into also in stator (16)；
The rotor bearing seat (2) is moved to below the rotor rear end again, and certain altitude of jack-uping, will be supported
Seat (1) and Mobile base (5) are set to below rotor bearing seat (2), are adjusted the installation through-hole and are directed at the threaded hole, and pass through
Bolt realizes being fixedly connected mounting seat (3) and support base (1) across threaded hole described in installation through-hole and precession, then delays
Slow descending jack so that rotor bearing seat (2) is placed on the Mobile base (5), and withdraws jack；
Slowly bearing is fixedly mounted so that the rear end of rotor is installed in the rotor bearing seat (2) in control driving after calibration again
Upper cover supports so that rotor rear end is fixedly installed in rotor bearing seat (2) and is formed to rotor rear end, then assists in lifting
The front position of axis sets up a support device, forms support by front end of the support device to lifting asessory shaft, unclamps suspender belt simultaneously
Suspender belt, is fixedly attached to the front end of lifting asessory shaft, hangs the front end of the rotor by mobile driving, and withdraws the support dress
It sets；
Finally, realizing control hydraulic cylinder (14) movement by control external motive device, and then is pushed and moved by hydraulic stem (15)
Dynamic seat (5) and rotor bearing seat (2) are mobile to motor stator (16) direction along axial direction, meanwhile, driving cooperation rotor bearing seat (2)
Movement and move, until Mobile base (5) be moved on the mounting seat (3), rotor is pierced into completely in stator (16) at this time,
The mounting hole in mounting hole alignment mounting seat (3) on rotor bearing seat (2) is adjusted, with jack by rotor bearing seat (2)
It jacks up, the support base (1) and Mobile base (5), descending jack is withdrawn, so that rotor bearing seat (2) is placed in the installation
It on pedestal (3), and is bolted to connection, the operating process for wearing rotor can be completed, subsequent installation process can be carried out.
