Face needs to be continuously improved.
Utility model content
The purpose of the present invention is to provide a kind of main body mounting structure of rotor of steam turbo generator, this structure has weight
Gently, the features such as easy for installation, high reliablity, it is particularly suitable for the generator rotor structure in high-speed cruising, rotor fortune can be improved
Capable safety, reliability.
To achieve the goals above, the utility model adopts the technical scheme that
Rotor of steam turbo generator main structure, including axis are arranged with rotor rim on the axis, and the rotor rim is each
It is arranged with pole coil and insulation spacer on muscle, is mounted on multiple pole shoes, Mei Gesuo on each muscle of the rotor rim
It states pole shoe and passes through screw and be mounted in rotor rim, and pole shoe offsets with pole coil, adjacent two of the rotor rim
Support is installed jointly on muscle, is mounted on bolt on each support, and bolt-through support and with rotor rim screw thread
Connection.
Preferably, it is handled by dipping lacquer and baking on each pole coil.
Preferably, washer is arranged on the bolt, and washer is between bolt and support.
Preferably, the screw is fixed by awl-end screw.
Preferably, insulation sleeve is arranged on the bolt, and insulation sleeve is between bolt and support.
Preferably, the rotor rim is set on axis by hot cover process.
The utility model is advantageous in that rotor rim guarantees the intensity of rotor rim using whole steel-casting processing,
It realizes that the tangential force between rotor rim and axis needs by hot cover process, so that rotor rim and axis are integrated, utilizes pole shoe
Pole coil is pressed in yoke surfaces with screw, increases insulating trip between pole coil and rotor rim, pole shoe, both guaranteed magnetic
Polar curve circle is fixed on the mechanical performance on rotor, and improves the insulating reliability of pole coil, by support, bolt by pole line
Lateral surface compressing is enclosed in rotor rim, improves the reliability of pole coil entirety, prevents running at high speed in the process out for generator
Existing pole coil loose phenomenon.
