D. heating temperature uniformly rises, and the swell increment of thin-wall part (2) is detected in heating process, waits for thin-wall part (2) diameter side
It when upward swell increment reaches 3mm, is kept the temperature, stops heating after temperature is constant；
E. using melt pit baseplane as working face, three supporting racks (5) are placed on working face, each supporting rack of pre-leveling
(5) planar horizontal on ensures that adjacent supports frame difference in height≤0.05mm, this process can be synchronous with heating thin-wall part (2) process；
F. plane places adjust cushion block (4) respectively on three supporting racks (5), adjusts cushion block (4) and is suitable for the thin of hot jacket
Wall pieces (2) length is more than the case where main shaft body hot jacket cooperation segment length, and contrary circumstance can be cancelled and adjust cushion block (4)；
G. it adjusts cushion block (4) to be located proximate near main shaft upper rotor part holder baseplane, after centering level, hangs in main shaft, directly
It connects to put off and adjust on cushion block (4), adjustment rotor field spider end face is horizontal；
H. the ceramic fiber cloth of thin-wall part (2) periphery for being heated to the amount of rising requirement is removed, loads onto four lifting lugs (6),
Then one end of UU types turnbuckle (10) is installed on lifting lug (6), the other end mounts lifting rope；
I. four UU types turnbuckle (10) length are adjusted, keep thin-wall part (2) end face horizontal, lifting thin-wall part (2) is put off
The position required to main shaft cooperation section, and ensure thin-wall part (2) hot jacket rear end face level, above-mentioned technique is without flange end main shaft
The process of vertical hot jacket.
Technique effect：
The present invention ensure that no flange end main shaft hot jacket component technology process by completing above-mentioned technique content.The present invention
Using support is stood in melt pit come fixed main shaft, avoid setting up mounting platform and installation height scaffolding on the ground, to drop
The sling height of component during low-heat set, while thin-wall part uses ceramic fiber cloth outside electromagnetic induction line during heating
Enclose again wrapping kept the temperature, when traditional heating component using heating furnace compared with, heating cost is low, effectively shorten installation week
Phase.
The present invention uses supporting rack by taking the main shaft hot jacket process of certain high tacho generator test model as an example in melt pit,
And using cushion block is adjusted by rotor field spider adjustment, enable no flange end main shaft axle body effectively perpendicular to the ground, using UU types
The component of hot jacket is carried out leveling by turnbuckle, improves the once success rate of main shaft hot jacket component.
