Description
Technical field
The utility model is a kind of brush motor assembly structure, particularly the assembly structure of a kind of brush motor stator chip and magnet ring, belongs to motor device mounting technology field.
Background technology
In current electromechanics trade, between brush motor stator chip endoporus and magnet ring outer rim, adopt matched in clearance, design extremely important during coordinating between stator chip endoporus with magnet ring outer rim, how to define the size in gap, also will consider process issues.After stator chip folds riveting, tolerance generally can control within 0.06mm, and magnet ring physical dimension is owing to considering the demoulding, so tolerance generally can control within 0.06mm.As shown in Fig. 1-1 to 1-3, the problem above comprehensive, the gap between stator chip endoporus and magnet ring outer rim is generally defined in 0.04-0.16mm.Gap portion adopts anaerobism glue to fill, thus magnet ring is fixed on stator chip.But in the said goods, can there is a more serious problem, be exactly poor stability, after magnet ring bonds, magnet ring inner surface is beated greatly, can affect on the one hand the uniformity that stator chip inner surface and magnet ring outer surface add glue, cause magnet ring to push away undercapacity, when causing motor oscillating, magnet ring loosens or comes off, motor air-gap can be there is on the other hand too small, the risk of magnet ring scraping, finally causes magnet ring to break, motor failure.
Utility model content
The purpose of this utility model is in the prior art for above-mentioned brush motor assembly structure, existence and stability is poor, beat and cause greatly motor oscillating excessive in magnet ring bonding rear surface, affect the uniformity that stator chip inner surface and magnet ring outer surface add glue, cause magnet ring to push away magnet ring when undercapacity causes motor oscillating loosen or come off, and it is too small to there is motor air-gap, magnet ring is swiped, the defect that magnet ring breaks, provide the assembly structure of a kind of brush motor stator chip and magnet ring, good stability can be reached, after magnet ring bonding, inner surface is without beating, motor oscillating is little, do not affect the uniformity that stator chip inner surface and magnet ring outer surface add glue, magnet ring can not be caused to push away magnet ring when undercapacity causes motor oscillating loosen or come off, motor air-gap is normal, magnet ring is not swiped, the object of not breaking.
The technical scheme that the utility model is taked to achieve these goals is: the assembly structure of a kind of brush motor stator chip and magnet ring, comprise stator chip and magnet ring, described magnet ring is arranged in stator chip endoporus, magnet ring outer rim and stator chip endoporus are matched in clearance, gap is 0.04-0.16mm, gap between magnet ring outer rim and stator chip endoporus adopts anaerobism glue to fill, thus stator chip is fixed in magnet ring outer rim;
4-8 section convex globoidal is provided with to projecting inward at stator chip endoporus, described convex globoidal and magnet ring outer rim are formed and closely cooperate, 4-8 section convex globoidal is evenly arranged in the gap between magnet ring outer rim and stator chip endoporus, and the angle of the corresponding motor center line of cross section of described convex globoidal is 7-15 °.
6 sections of convex globoidals are provided with to projecting inward at stator chip endoporus.
The angle of the corresponding motor center line of cross section of described convex globoidal is 10 °.
The height of described convex globoidal is 0.06mm.
Compared with prior art, the beneficial effects of the utility model are:
Good stability, brush motor stator chip and magnet ring assemble and adopt the friction tight design in local, stator chip adopts local to closely cooperate with magnetic ring inner hole in design, assembling is not affected when ensureing cooperation, also glue curing is not affected, the design of this innovation perfectly solves magnet ring and to beat the problem of large problem and stator balance, product stability is good, after magnet ring bonding, inner surface is without beating, motor oscillating is little, do not affect the uniformity that stator chip inner surface and magnet ring outer surface add glue, magnet ring can not be caused to push away magnet ring when undercapacity causes motor oscillating loosen or come off, motor air-gap is normal, magnet ring is not swiped, do not break, be applicable to all brush motor series products.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
As shown in Fig. 2-1 to Fig. 2-4, the assembly structure of a kind of brush motor stator chip and magnet ring, comprise stator chip 1 and magnet ring 2, described magnet ring 2 is arranged in stator chip 1 endoporus, magnet ring 2 outer rim and stator chip 1 endoporus are matched in clearance, gap 3 is 0.04-0.16mm, and the gap 3 between magnet ring 2 outer rim and stator chip 1 endoporus adopts anaerobism glue to fill, thus stator chip 1 is fixed in magnet ring 2 outer rim;
6 sections of convex globoidals 101 are provided with to projecting inward at stator chip 1 endoporus, described convex globoidal 101 is formed with magnet ring 2 outer rim and closely cooperates, 6 sections of convex globoidals 101 are evenly arranged in the gap 3 between magnet ring 2 outer rim and stator chip 1 endoporus, and the angle α of the corresponding motor center line of cross section of 6 sections of convex globoidals 101 is 10 °.
