Description
Technical field
The utility model relates to the technical field of half directly-drive permanent magnet generator amature support component, refers in particular to a kind of half directlyDrive rotor of permanent-magnetic power generator supporting structure.
Background technology
At present, domestic rotor field spider mostly is Welding Structure, and concrete structure is for adopting steel plate to roll into cylinder, useA steel plate that cuts into toroidal is placed into cylinder interior centre position and welds, and then adds several along the circumferential directionUniform gusset is welded, and this structure is comparatively simple, but the greatly and easily distortion of welding job amount, its appearance and size andCenter of gravity is all difficult to control, and this is a very large defect for large-scale rotor, because in the process of rotating at generator,If rotor eccentricity can cause the vibration of generator to strengthen, finally may cause the even damage of generator self of dynamo bearingBad.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of half directly-drive permanent magnet generator amature to prop upShelf structure, the rotor field spider malformation amount that can effectively solve welding is large, the problem of processing difficulties and to alleviate loaded down with trivial details school movingBalance work, reduces the production cost in generator amature processing and assembling process, the reliability while increasing generator operation.
For achieving the above object, technical scheme provided by the utility model is: a kind of half directly-drive permanent magnet generator amatureSupporting structure, described rotor field spider is the integral structure that adopts casting, by support outer ring, supporting construction and mounting structureComposition; Described support outer ring is cylinder-like structure, and outer surface becomes smooth polyhedron by Milling Process, and the processing of cylinder two endsHave seam, location while installation for the rotor magnetic pole of half directly-drive permanent magnet generator, is radially drilled with along cylinder from cylinder inner surfaceCircumferentially uniform counterbore, for rotor magnetic pole is installed, is fixed on rotor magnetic pole on rotor field spider outer surface, bores at cylinder two endsHave screwed hole, for two centrifugal fans are installed, described centrifugal fan in the time that generator amature rotates as generator skyThe power that gas circulates, makes the cold and hot air circulation cooled electric generator that flows; Described supporting construction is circulus, is positioned at cylinderOne end, becomes as a whole for connection bracket outer ring with mounting structure, circumferentially has multiple logical in described supporting construction along itWind hole, this air vent is the important component part of generator cooling air duct, is the logical of generator cooling air circulation circulationRoad; Described mounting structure is frusto-conical configuration, is the assembled portion of rotor field spider, and its cone end is connected with supporting construction, itsThe vertex of a cone is processed with seam and is drilled with screwed hole, for being connected with the adpting flange of rotor field spider assembling.
Described air vent is tri-angle-holed.
Compared with prior art, tool has the following advantages and beneficial effect the utility model:
1, can be according to the position of electric generator structure Demand Design rotor field spider center of gravity, and the position of center of gravity is for rotary bodyBe considerable, for example rotary body bias produces larger vibration, therefore position of centre of gravity can cause rotary body motion timeIt is the key factor that rotary body is paid close attention to.
2, rigging position, near the design of one end, can make the spacing of two groups of bearings of generator suitably strengthen, and obtains betterStability.
3, frusto-conical configuration is very beneficial for the molding sand demoulding, has reduced to a great extent casting difficulty.
4, the design adopts casting structure to also have a series of significant advantages, is mainly manifested in its compact conformation, quality is equalEven, position of centre of gravity is comparatively fixing, otherness when batch production between individuality is less etc.
Comprehensive above-mentioned some is known, and these features are extremely beneficial in rotor, and in rotor field spider processing andWhen assembling, can reduce very large workload, for example, when generator amature does dynamic balancing, if center of gravity deviation is larger, required joinsHeavy balance weight weight also increases thereupon, and needs long adjustment, and center of gravity required balance weight weight while approaching axle centerCan be less, not only reduce workload, also help the reliability that increases generator. Due between generator amature and statorGap is less, will reduce as much as possible vibration and distortion while therefore requiring rotor high-speed rotation, avoids because of vibration or be out of shape causingGenerator amature and stator wiping are touched and cause generator to damage, and the design's rotor field spider can better address this problem,For ensureing that the normal operation of generator provides reliable guarantee.
