Abstract
The invention discloses a large double-fed asynchronous generator rotary shaft with an overlong shaft distance. Iron spokes are uniformly arranged at an iron core blocking part of the rotary shaft along the circumferential direction. The large double-fed asynchronous generator rotary shaft has the characteristics that the iron spoke structure is arranged at the iron core blocking part of the rotary shaft, so that the strength and long-term safe and stable operation requirements of a machine unit on the generator rotary shaft under different operation working conditions can be satisfied, and the weight of the rotary shaft is also reduced.
Description
Technical field
The present invention relates to the generator designs field, be specifically related to a kind of large-scale double-fed asynchronous generator rotating shaft of Super Long-axles spacing.
Background technique
In common asynchronous motor, distance between shafts is generally below 1.5m, rotor weight is lighter, the countershaft requirement of strength satisfies easily, the general following common circular shaft material of Φ 200mm that adopts can satisfy requirement of strength, and for the design of the large-scale double-fed asynchronous generator rotating shaft of Super Long-axles spacing, on original common electric machine base of design, can't satisfy the designing requirement of countershaft intensity.
Summary of the invention
The object of the invention is to overcome above-mentioned not enough problem, a kind of large-scale double-fed asynchronous generator rotating shaft of Super Long-axles spacing is provided.
The technological scheme that the present invention adopts for achieving the above object is: the large-scale double-fed asynchronous generator rotating shaft of Super Long-axles spacing, the iron core gear place of rotating shaft along the circumferential direction evenly is provided with the iron spoke.
Be welded with six described iron spokes in the described rotating shaft, and described iron spoke is rectangle.
The length of six described iron spokes, highly all identical, wherein two symmetrical iron spoke width are identical, and the width of other four iron spokes is identical.
Characteristics of the present invention are: adopt iron spoke structure at the iron core gear place of rotating shaft, can satisfy unit under different operating conditionss to the intensity of alternator shaft and the requirement of long-term safety stable operation, also alleviated the weight of rotating shaft.
Description of drawings
Fig. 1 is plan view of the present invention;
Fig. 2 is side view of the present invention.
Wherein: 1, rotating shaft 2, iron spoke
Embodiment
Such as Fig. 1, shown in 2, the present invention adopts iron spoke 2 structures at the iron core gear place of rotating shaft 1, namely at six iron spokes 2 of circumferencial direction uniform welding of rotating shaft 1, and described iron spoke 2 is rectangle, rotating shaft 1 and iron spoke 2 materials are 42CrMo, the length of six described iron spokes 2, highly all identical, consider and turn from the punching keyway, so wherein two symmetrical iron spoke 2 width are identical, the width of other four iron spokes 2 is identical, and the width of four identical iron spokes 2 of Width of two identical iron spokes 2 is large, adopts this structure can satisfy the requirement of strength of rotating shaft 1, also can alleviate the weight of rotating shaft 1.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technological scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
