Abstract
The utility model provides a large and medium motor interlinkage fanning strip, comprising a plurality of fanning stampings which are surrounded into a whole circular, a seam is arranged between every two adjacent fanning strips, the seam between the two adjacent fanning strips is in an Omega wave shape. The utility model can effectively control the radial and the tangential displacements between the fanning strips, and the groove shape and the groove number of the fanning strip are uncommitted.
Description
Technical field
The utility model relates to a kind of link fanning strip, relates in particular to a kind of large and middle size motor with linking fanning strip.
Technical background
The full circle punching out is adopted in the punching of general diameter below 1000mm, still, when the punching external diameter of large and middle size motor greater than 1000mm, when surpassing the manufacturing width of existing silicon steel plate, just can't directly carry out the full circle punching out.Big and can not adopt the punching of full circle for diameter, generally adopt fan-shaped punching out, carry out closed assembly with fanning strip.
See also Fig. 1, a kind of fanning strip for prior art comprises some fanning strips, which is provided with stretching screw hole 2 ', and every fanning strip 4 ' needs to use the gangdie punching out, and its flute profile, groove number are fixed.The seam crossing of sheet and sheet just in time is the center of groove 3 ', and fanning strip 4 ' is fixed with the keyway 5 ' that has on the sheet.Behind the staggered lamination, each fanning strip 4 ' location is strained by stretching screw.Because its seam 1 ' locates to adopt straight line, can produce radially and tangential displacement between the adjacent fanning strip 4 '.During lamination, very high to the positioning requirements of the location of the location in stretching screw hole 2 ', groove 3 ' and keyway 5 ', determine that the degree of freedom of groove number is extremely low, manufacturing process is more loaded down with trivial details, when flute profile changes, need drive compound press tool again, and cost improves greatly.
Summary of the invention
So the purpose of this utility model is providing a kind of large and middle size motor with linking fanning strip for the defective that overcomes prior art, it can effectively control between the fanning strip radially and tangential displacement, make it become an integral body, and make the flute profile of fanning strip, groove number unfettered.
The technical scheme that realizes above-mentioned purpose is: a kind of large and middle size motor comprises the some segmental punchings that surround a full circle shape with the link fanning strip, between the per two adjacent fanning strips seam is arranged, and wherein, the seam between the described two adjacent fanning strips is the Ω waveform.
Above-mentioned a kind of large and middle size motor is with linking fanning strip, and wherein, the external diameter of the full circle shape punching that described some fanning strips surround is more than or equal to 1000mm.
Above-mentioned a kind of large and middle size motor is with linking fanning strip, and wherein, described fanning strip is six.
Above-mentioned a kind of large and middle size motor is with linking fanning strip, wherein, be made up of four first fanning strips and two second fanning strips in described six fanning strips, this first fanning strip is 29 grooves, second fanning strip is 28 grooves, and wherein folder is established two first fanning strips between two second fanning strips.
The beneficial effects of the utility model are: a kind of large and middle size motor of the present utility model is with linking fanning strip, connecing between the two adjacent fanning strips met and adopted the Ω waveform, this structure can make radially being effectively controlled with tangential displacement between fanning strip, reduced the positioning requirements of stretching screw hole and keyway, and after fanning strip is spliced into a circle, available single impression die punching out, its flute profile is unfettered.Under the variable situation of flute profile, the punch die cost reduces greatly.
Description of drawings
Fig. 1 is the structural representation of the link fanning strip of prior art;
Fig. 2 is the structural representation of a kind of large and middle size motor of the present utility model with the link fanning strip.
Embodiment
Below in conjunction with accompanying drawing a kind of large and middle size motor link fanning strip of the present utility model is described further.
See also Fig. 2, show a kind of large and middle size motor of the present invention with linking fanning strip, it comprises the some segmental punchings 11 that surround full circle shape punching 1, and the external diameter of this full circle shape punching 1 is more than or equal to 1000mm, between the per two adjacent fanning strips 11 seam 12 is arranged, this seam 12 is the Ω waveform.
In the present embodiment, the motor stamping diameter is 1240mm, the groove number is 172, adopt six fanning strips 11 to surround a full circle shape punching 1, form by four first fanning strips 111 and two second fanning strips 112 in these six fanning strips, this first fanning strip 111 is 29 grooves, and second fanning strip 112 is 28 grooves, and wherein folder is established two first fanning strips 111 between two second fanning strips 112.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection range of the present utility model.
