The commutator segment comprises a commutator segment body, and fixing foots arranged at the inner side of the commutator segment body, wherein the fixing foots extend to the top from the bottom of the commutator segment body along the axial direction of the commutator, and the cross sections of the fixing foots are swallowtail-shaped.
Description
Technical field
The utility model relates to commutator, is specifically related to a kind of commutator segment that is applied to the improvement structure on the 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 Rotation Speed, commutator need to bear the huge centrifugal force that motor when rotation produces, otherwise can produce the bad phenomenon such as the film flying of commutator segment or floating sheet.Therefore, for the adhesive force between the inserts that increases commutator segment and commutator, usually can fixing feet be set in the commutator segment inboard; 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, China Patent Publication No. CN201781173U, open day on 03 30th, 2011, the name of innovation and creation is called the commutator segment of Hooked reverser, this application case discloses a kind of commutator segment of Hooked reverser, comprise commutator segment body, commutator segment hook portion, the arc groove that the dual-side of described 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 a straight-bar as the fixing feet of commutator segment, therefore adhesion effect is relatively poor between the inserts of commutator segment and commutator, at motor when High Rotation Speed moves, produce easily the bad phenomenon such as the film flying of commutator segment or floating sheet, affect quality and the life-span of commutator.
The utility model content
The purpose of this utility model be for adhesion effect between the inserts of the commutator segment that overcomes existing commutator and commutator not good, produce easily the film flying of commutator segment or the problem of floating sheet phenomenon, provide a kind of and be connected firmly with the inserts of commutator, and can improve the quality of ringing commutator and the commutator segment in life-span.
The technical solution of the utility model is:
A kind of commutator segment that improves structure comprises the commutator segment body and is arranged on the fixing feet of commutator segment body inboard, and described fixing feet axially extends to the top by commutator segment body bottom along commutator, and the cross section of described fixing feet is swallow-tail form.Because fixing feet extends to the top by commutator segment body bottom, it has increased the contact area between the inserts of commutator segment and commutator, the adhesive force between the inserts of increase commutator segment and commutator.Simultaneously, because the cross section of fixing feet is swallow-tail form, it has not only improved the contact area between the inserts of commutator segment and commutator, and effectively improve adhesive force radially between the inserts of commutator segment and commutator, and then effectively overcome the huge centrifugal force that motor produces when High Rotation Speed moves, thereby effectively improve film flying or the floating sheet phenomenon of commutator segment, improve quality and the life-span of ringing commutator.
As preferably, be provided with successively from top to bottom the first double wedge, the second double wedge, the 3rd double wedge, the 4th double wedge along the commutator radial protrusion on the medial surface of fixing feet.This programme structure can further 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, be provided with dovetail groove between the first double wedge and the second double wedge, also be provided with dovetail groove between the 3rd double wedge and the 4th double wedge, be provided with U-lag between the second double wedge and the 3rd double wedge.Because between the first double wedge and the second double wedge and be respectively equipped with dovetail groove between the 3rd double wedge and the 4th double wedge, therefore after the inserts of commutator is fixed-type, inserts can be filled in the dovetail groove, and inserts and the first double wedge, the second double wedge, the 3rd double wedge and the 4th double wedge are linked together closely; The radial and axial adhesive force between commutator segment and the inserts be can effectively improve, thereby film flying or the floating sheet phenomenon of commutator segment effectively solved.
As preferably, the cross section of the first double wedge, the second double wedge, the 3rd double wedge and the 4th double wedge is in T shape.This programme structure has not only improved the contact area between the inserts of commutator segment and commutator, and can effectively improve the adhesive force radially between the inserts of commutator segment and commutator, thereby effectively improves film flying or the floating sheet phenomenon of commutator segment.
As preferably, the first double wedge and the 4th double wedge are symmetrical arranged, and described the second double wedge and the 3rd double wedge are symmetrical arranged.This programme structure so that the adhesive force between the inserts of commutator segment and commutator be evenly distributed.
As preferably, the top of commutator segment body is provided with a crooked crotch laterally.
As preferably, the outer side edges of the cross section of commutator segment body is circular arc, and inner side edge is shape linearly, and the width of the cross section of commutator segment body is reduced toward interior gradually by the outside.
The beneficial effects of the utility model are: improve greatly the radial and axial adhesive force between the inserts of commutator segment and commutator; Thereby effectively overcome the huge centrifugal force that motor produces when High Rotation Speed moves, solve film flying or the floating sheet phenomenon of commutator segment, improve quality and the life-span of ringing commutator.
