Abstract
The utility model discloses a commutator sheet of a groove type commutator, which aims at providing a commutator sheet which can effectively solve the flying sheet or floating sheet phenomenon of the commutator sheet and prolong the quality and the service life of the commutator and can also economize the material consumption of the commutator sheet and lower the cost. The commutator sheet comprises a commutator sheet main body and fixing pins arranged at the inner side of the commutator sheet main body, the commutator sheet main body is an inverted L shape, and the cross section of the fixing pins is T shape.
Description
Technical field
The utility model relates to commutator, is specifically related to a kind of commutator segment of improvement structure of tank commutator.
Background technology
Commutator is as one of important component part of direct current machine, and its intensity and performance are extremely important to the stable operation of motor.When motor moved at high speed rotating, commutator need bear the huge centrifugal force that the motor rotation time is produced, otherwise can produce the bad phenomenon such as film flying or floating sheet of commutator segment.Therefore, for the adhesive force between the inserts that increases commutator segment and commutator, can fixing feet be set in the commutator segment inboard usually; But the fixing feet of present commutator segment is simple in structure, and the contact area between the inserts of fixing feet and commutator is less, can not effectively improve the adhesive force between the inserts of commutator segment and commutator.For example; Chinese patent publication number CN201781173U, open day on 03 30th, 2011, the name of innovation and creation was called the commutator segment of hook commutator; This application case discloses a kind of commutator segment of hook commutator; Comprise commutator segment body, commutator segment hook portion, the arc groove that the dual-side of said commutator segment hook portion at its crotch place has indent, thereby effective protective paint envelope curve; But the inboard of the commutator segment of this application case only is provided with the fixing feet of a straight-bar as commutator segment; Therefore adhesion effect is relatively poor between the inserts of commutator segment and commutator; At motor when high speed rotating moves; Be easy to generate the bad phenomenon such as film flying or floating sheet of commutator segment, influence the quality and the life-span of commutator.
The utility model content
The purpose of the utility model be for adhesion effect between the inserts of commutator segment that overcomes existing commutator and commutator not good; Be easy to generate the film flying of commutator segment or the problem of floating sheet phenomenon; Providing a kind of is connected firmly with inserts commutator; Can improve the quality and the life-span of commutator, the commutator segment that can also practice thrift the commutator segment material usage, reduce cost simultaneously.
The technical scheme of the utility model is:
A kind of commutator segment of tank commutator comprises the commutator segment body and is arranged on the inboard fixing feet of commutator segment body that the commutator segment body is the font of falling L, and the cross section of said fixing feet is the T font.Because the cross section of fixing feet is the T font; It has not only improved the contact area between the inserts of commutator segment and commutator; And the fixing feet that is the T font can effectively improve the adhesive force radially between the inserts of commutator segment and commutator; And then effectively overcome the huge centrifugal force that motor is produced when high speed rotating moves, thus effectively improve the film flying or the floating sheet phenomenon of commutator segment, improve the quality and the life-span of commutator.
As preferably, fixing feet comprises root that is connected with the commutator segment body and the head that is positioned at the root outside, and said root side is provided with at least two fixed holes, and the two ends of root are respectively equipped with the retention grooves that is the U font.Because the root side of fixing feet is provided with at least two fixed holes; And the two ends of root are respectively equipped with the retention grooves that is the U font; Therefore when the inserts of commutator fixedly after the moulding, inserts can be filled in fixed hole and the retention grooves, and inserts and fixing feet are linked together closely; The radial and axial adhesive force between commutator segment and the inserts be can effectively improve, thereby the film flying or the floating sheet phenomenon of commutator segment effectively solved.Simultaneously fixed hole and retention grooves all right economical with materials is set, reduce cost.
As preferably, fixed hole is a rectangular opening, and the width of fixed hole is identical with the width of root.Because the width of fixed hole is identical with the width of root, it is economical with materials farthest, reduces cost.Simultaneously can also improve the radial and axial adhesive force between commutator segment and the inserts.
As preferably, fixing feet extends to the top by commutator segment body bottom.This programme can improve the contact area between the inserts of commutator segment and commutator, increases the adhesive force between the inserts of commutator segment and commutator.
As preferably, the cross section of commutator segment body is the big inboard little isosceles trapezoid shape in the outside.This programme structure can practice thrift the commutator segment body material usage, reduce cost.
The beneficial effect of the utility model is: improve the adhesive force radially between the inserts of commutator segment and commutator greatly, thereby effectively solve the film flying or the floating sheet phenomenon of commutator segment, the quality and the life-span of improving commutator; Can also practice thrift the commutator segment material usage simultaneously, reduce cost.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is a kind of generalized section of the cross section of the utility model.
Among the figure: commutator segment body 1, fixing feet 2, root 3, head 4, fixed hole 5, retention grooves 6.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Like Fig. 1, shown in Figure 2, a kind of commutator segment of tank commutator comprises commutator segment body 1 and is arranged on the inboard fixing feet 2 of commutator segment body.Commutator segment body 1 is the font of falling L.The cross section of commutator segment body 1 is the big inboard little isosceles trapezoid shape in the outside.Said fixing feet 2 extends to the top by commutator segment body bottom.The cross section of fixing feet 2 is the T font.Fixing feet 2 comprises root 3 that is connected with commutator segment body 1 and the head 4 that is positioned at the root outside.Said root 3 sides are provided with two fixed holes 5, and the two ends of root are respectively equipped with the retention grooves 6 that is the U font.Fixed hole 5 is a rectangular opening, and the width of fixed hole 5 is identical with the width of root 3.
Because the cross section of fixing feet 2 is the T font, and the root 3 of fixing feet 2 is provided with two fixed holes 5 and two retention grooves 6; When the inserts of commutator fixedly after the moulding, inserts can be filled in fixed hole and the retention grooves, and inserts and fixing feet are linked together closely; Can effectively improve the radial and axial adhesive force between commutator segment and the inserts; Therefore can effectively overcome the huge centrifugal force that motor is produced when high speed rotating moves; Effectively solve the film flying or the floating sheet phenomenon of commutator segment, the quality and the life-span of improving commutator.
