Abstract
A stator core device of a power generator comprises the components of: stator fan-shaped sheets, pressing rings, a buckling sheet and ribs. A plurality of stator fan-shaped sheets are stacked to a cylindrical structure. The upper end and the lower end of the cylindrical structure are respectively provided with a pressing ring. The outer periphery of the cylindrical structure is connected with a plurality of ribs. The buckling sheet is connected with the pressing rings and the cylindrical structure through a welded structure. The central part of each rib is provided with a plurality of threaded holes. The stator core device of the power generator provided by the utility model has advantages of: realizing simple structure, high production efficiency, reliable quality and low cost; facilitating steps of stator coil unloading and paint dipping, etc.; improving production efficiency of the whole power generator; and reducing manufacturing cost of the power generator.
Description
Technical field
The utility model relates to a kind of stator core, relates in particular to a kind of generator stator core device.
Background technology
The different material of generator stator and rotor use conventionally unshakable in one's determination, is the utilance that improves stator core material, and stator punching is made the fan-shaped circle that is combined into conventionally.The stator core of small power generator adopts stator sector piece, trim ring, cramp to be welded into outer press mounting stator core conventionally.For the stator core of high-power generator, owing to being that stator punching is fanning strip, the outer press mounting stator core being welded into stator sector piece, trim ring, cramp can not ensure the reliable in quality of stator core.Therefore the stator core of high-power generator adopt in support lamination be shaped in press-fit stator core.And the generator production efficiency that press-fits stator core in adopting is low, cost is high, the production cycle is long.
Summary of the invention
The purpose of this utility model is to provide a kind of generator stator core device, and it has advantages of simple in structure, reliable and practical and cost is low.
The utility model is achieved like this, it comprises stator sector piece, trim ring, cramp and rib, it is characterized in that, several stator sector pieces laminate into cylindrical shape structure, the two ends up and down of cylindrical shape structure are fixed with a trim ring by cramp respectively, and the periphery of cylindrical shape structure is connected with several ribs; Described cramp connects trim ring and cylindrical shape structure by Welding Structure; In the middle of described rib, be provided with several screwed holes.
Technique effect of the present utility model is: the utility model is simple in structure, production efficiency is high, reliable in quality, cost are low.It can facilitate the operations such as stator coil rolls off the production line, dipping lacquer to produce, and improves the production efficiency of whole generator, the manufacturing cost of reduction generator.
Brief description of the drawings
Fig. 1 is structural front view of the present utility model.
Fig. 2 is structure vertical view of the present utility model.
Stator sector piece 2, trim ring 3, cramp 4, rib in the drawings, 1.
Embodiment
As depicted in figs. 1 and 2, the utility model is achieved like this, it comprises stator sector piece 1, trim ring 2, cramp 3, rib 4, its design feature is that stator sector piece 1 is laminated into cylindrical shape structure, fix a trim ring 2 by cramp 3 is each up and down, be then symmetrically welded rib 4 at its cylindrical.
In stator core pendulum tire, first place a trim ring 2, cramp 3, then stator sector piece 1 be put into cylindrical shape, then on stator sector piece 1, place a trim ring 2, compress with hydraulic press, with electric welding by cramp 3 and stator sector piece 1, trim ring 2 firm welding.Remove pendulum tire, centre is drilled with to the rib 4 and stator sector piece 1, trim ring 2 firm welding of screwed hole.Stator core can be sling and turned over by the screwed hole in the middle of rib 4 and turn 90 degrees.It is simple in structure, production efficiency is high, reliable in quality, cost are low.It can facilitate the operations such as stator coil rolls off the production line, dipping lacquer to produce, and improves the production efficiency of whole generator, the manufacturing cost of reduction generator.
