Abstract
A kind of generator rotor support structure, comprise rotor field spider structural body, it is characterized in that: described rotor field spider structural body is welded with curvature, uniform pore openings on described curvature, some studs are had in hole, rotor field spider structural body and magnetic pole link into an integrated entity by described studs and nut screw connection, described rotor field spider structural body is processed by steel plate materials, described curvature steel plate bends and forms, described studs has 3 at least, the material used due to rotor field spider is steel plate, because the mechanical index of steel plate is higher than ironcasting, can be thinning at guarantee equal strength lower member, therefore materials reduce, blank manufacturing process is few, technique is uncomplicated, only form with Plate Welding, easy for installation, manufacturing cycle is short, save space, place, with low cost.
Description
Technical field
The utility model relates to a kind of rotor field spider structure, specifically relates to a kind of medium and small generator rotor field spider structure.
Background technology
The pole core of generator and coil are the key core parts of generator, and the structure supporting this part is exactly rotor field spider.When generator normally runs, rotor field spider will bear gravitational moment, the effect such as centrifugal force of self of moment of torsion, magnetic pole and yoke.
At present when frame diameter is 4100mm-6400mm, rotor field spider is generally the ironcasting product processed from strand, and utilizes T tail or dove tail yoke and rotor field spider to be fixed after rim lamination.Ironcasting itself also exists manufacturing process complexity, the problem that manufacturing process is loaded down with trivial details.The manufacture process of an ironcasting will pass through multiple working procedures such as manufacturing die model, sand mold, ironmaking, cast, sand removal and per pass procedure technology requires all high, because the mechanical performance index of cast iron quality is not high, meet the requirement of strength of the structural member of high-rating generator, casting dimension must be thickeied, this must cause ironcasting not only heavily but also stupid, thus the raw material used increase, and cause the ironcasting manufacturing cycle long for above-mentioned reasons, use raw material are many, thus make cost sharply increase.
Magnet yoke blanking sheet needs punching in addition, and lamination becomes yoke, needs special stack mounting tool and closed assembly place during rim lamination, and be fixed on rotor field spider by yoke by dove tail or T tail, operation is various, and the manufacturing cycle is long, and cost is corresponding also to be increased.
Utility model content
The utility model generator rotor support structure is solve the above-mentioned problem points that has or shortcoming, provides a kind of materials'use few, technique is simple, easy for installation, rotor field spider structure that the manufacturing cycle is short.
To achieve these goals, the utility model rotor field spider structure realizes by following technical scheme:
This generator rotor support structure, comprise rotor field spider structural body, it is characterized in that: described rotor field spider structural body is welded with curvature, uniform pore openings on described curvature, have some studs in hole, rotor field spider structural body and magnetic pole link into an integrated entity by described studs and nut screw connection.
Further, described rotor field spider structural body is processed by steel plate materials.
Further, described curvature steel plate bends and forms.
Further, described studs has 3 at least.
The beneficial effects of the utility model are: the material used due to rotor field spider structural body is steel plate, because the mechanical performance index of steel plate is higher than ironcasting, can be thinning at guarantee equal strength lower member, therefore materials reduce, blank manufacturing process is few, technique is uncomplicated, only with Plate Welding composition, easy for installation, the manufacturing cycle is short, save space, place, with low cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the schematic diagram of the original rotor field spider structure of generator.
Wherein Reference numeral is expressed as: 11-conventional rotors support, 12-laminated yoke, 13-magnetic pole.
Fig. 2 is the schematic diagram of novel electricity generator rotor field spider structure.
Wherein Reference numeral is expressed as: 1-rotor field spider structural body, 2-curvature, 3-studs, 4-nut, 5-magnetic pole.
Detailed description of the invention
Below in conjunction with drawings and Examples, further illustrate the utility model.
As shown in Figure 1, conventional rotors support 11 is generally the product that ironcasting processes from strand, laminated yoke 12 is formed after rim lamination, laminated yoke 12 and magnetic pole 13 adopt T-shaped or dove tail shape to be connected, ironcasting itself also exists manufacturing process complexity, the problems such as manufacturing process is loaded down with trivial details, the manufacture process of an ironcasting will through manufacturing die model, sand mold, ironmaking, cast, the multiple working procedures such as sand removal and per pass procedure technology require all high, because the mechanical performance index of cast iron quality is not high, meet the requirement of strength of the structural member of large-size machine, just casting dimension must be thickeied, this must cause ironcasting not only heavily but also stupid, the raw material used are many, cause the ironcasting manufacturing cycle long, use raw material many, thus make cost sharply increase.Magnet yoke blanking sheet needs punching lamination in addition, needs special stack mounting tool during rim lamination, closed assembly place, and operation is various, and the manufacturing cycle is long, and cost is corresponding also to be increased.
Novel rotor supporting structure as shown in Figure 2, comprise rotor field spider structural body 1, rotor field spider structural body 1 is welded with curvature 2, uniform pore openings on curvature 2, some studs 3 are had in hole, studs 3 coordinates with nut 4 and rotor field spider structural body 1 and magnetic pole 5 is linked into an integrated entity, rotor field spider structural body 1 is processed by steel plate materials, curvature steel plate bends and forms, the studs coordinated has 3 at least, such structure is convenient to components welding and is shaped and eliminates punching magnet yoke blanking sheet, rim lamination and various additional equipment and place.Because the mechanical index of steel plate is higher than ironcasting, can be thinning at guarantee equal strength lower member, therefore materials reduce, blank manufacturing process is few, and technique is uncomplicated, and only with Plate Welding composition, easy for installation, the manufacturing cycle is short, saves space, place, with low cost.
Above embodiment, only in order to the technical solution of the utility model to be described, can not limit scope of the present utility model with this; To the amendment that the technical scheme described in foregoing embodiments is carried out, or to the equivalent replacement that wherein portion of techniques feature is carried out, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model, all should still belong in scope that the utility model patent contains.
