Description
Technical field
The present invention relates to turbo-generator end coil support structure, specifically rotor of steam turbo generator end coil combined pad supporting construction, belongs to motor device technical field.
Background technology
Turbo generator is high-speed electric expreess locomotive, and rotating speed is high, and during operation, rotor oscillation is large, and centrifugal force is large.Rotor tip winding stretches out rotating shaft, when motor runs, by powerful centrifugal action, can deformation be there is, if deformation is large, rotor coil turn-to-turn short circuit can be caused, coil burnout, affect the reliability service of turbo generator, therefore rotor tip winding is wanted fixation, reliably, the high fixed form of a kind of fail safe need be adopted to ensure that the reliable normal of turbo generator runs.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of rotor of steam turbo generator end coil combined pad supporting construction is provided, its structure is simple, safe and reliable, the integral rigidity of rotor of steam turbo generator End winding can be strengthened, reduce the deformation of rotor of steam turbo generator End winding, and then ensure turbo generator safe and reliable operation.
According to technical scheme provided by the invention: rotor of steam turbo generator end coil combined pad supporting construction, it is characterized in that: comprise retaining ring, dead ring and combined pad, described rotor end turn coils stretches out rotating shaft, combined pad is positioned between rotor end turn coils, dead ring is arranged outside rotor end turn coils, fix with retaining ring outside dead ring, dead ring is guaranteed to insulate between rotor end turn coils and retaining ring.
As a further improvement on the present invention, described combined pad comprises big cushion block and small cushion block, and described big cushion block is positioned between rotor end turn coils, with support rotor end coil; Described big cushion block top is provided with breach, and can move up and down adjustment in the breach that small cushion block is placed on big cushion block, on small cushion block, plane and rotor end turn coils keep concordant.
As a further improvement on the present invention, terylene felt is filled with in the gap of described small cushion block and big cushion block breach.
As a further improvement on the present invention, described small cushion block may be combined with between big cushion block or is separated use completely.
compared with prior art, advantage is in the present invention:structure of the present invention is simple, safe and reliable, its by arrange can be Height Adjustable combined pad, make can obtain between rotor end turn coils fully supporting fixing, there will not be the situation that rotor end turn coils does not have cushion block to support, the integral rigidity of rotor of steam turbo generator End winding can be strengthened, reduce the deformation of rotor of steam turbo generator End winding, and then ensure turbo generator safe and reliable operation.

Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure: the rotor of steam turbo generator end coil combined pad supporting construction in embodiment forms primarily of retaining ring 1, dead ring 2 and combined pad, described rotor end turn coils 3 stretches out rotating shaft 6, combined pad is positioned between rotor end turn coils 3, dead ring 2 is arranged outside rotor end turn coils 3, fix with retaining ring 1 outside dead ring 2, dead ring 2 is guaranteed to insulate between rotor end turn coils 3 and retaining ring 1.
As shown in Fig. 1 ~ Fig. 6, in the embodiment of the present invention, described combined pad forms primarily of big cushion block 4 and small cushion block 5, and described big cushion block 4 is positioned between rotor end turn coils 3, with support rotor end coil 3; Described big cushion block 4 top is provided with breach 4a, and can move up and down adjustment according to matching requirements in the breach 4a that small cushion block 5 is placed on big cushion block 4, on small cushion block 5, plane keeps concordant with rotor end turn coils 3.Preferably terylene felt is filled in described small cushion block 5 and the gap of big cushion block 4 breach 4a.
In the present invention, described small cushion block 5 is capable of being combined with between big cushion block 4 or be separated use completely, assembles use to facilitate turbo generator.
During concrete installation application, after rotor end turn coils 3 rule to rotating shaft 6 li, big cushion block 4 is positioned between rotor end turn coils 3, for wedging rotor end turn coils 3.Small cushion block 5 is placed in the breach 4a at big cushion block 4 top, if plane is lower than rotor end turn coils 3 on small cushion block 5, is then upwards regulated by small cushion block 5, and after regulating, small cushion block 5 is filled with terylene felt with the gap of big cushion block 4 breach 4a.If plane is concordant with rotor end turn coils 3 on small cushion block 5, then without the need to regulating small cushion block 5.
It should be noted that, above-described is only the preferred implementation of patent of the present invention, and patent of the present invention is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite of the spirit and design that do not depart from patent of the present invention, all should think be included in patent of the present invention protection range within.
