Abstract
The utility model embodiment discloses a kind of Novel commutator, the Novel commutator is cylindrical structure, side spaced set has copper sheet, mica sheet is provided between copper sheet, in one end of Novel commutator, copper sheet and mica sheet extend radially outward, and form winding connecting portion, the outer surface of copper sheet in winding connecting portion is provided with a groove, and depth of groove is less than the radius of outside copper cash.Implement the utility model embodiment, have the advantages that：The groove of the winding connecting portion of this Novel commutator is more shallow than the groove of traditional commutator a lot, outside copper cash is connected by the soldering lug of thawing with commutator, this connected mode connection is closer, effectively increase the reliability and service life of product, and because groove is shallow a lot, centrifugal force when commutator rotates declines a lot, while also saves copper material.
Description
Technical field
It the utility model is related to a kind of motor component, more particularly to a kind of Novel commutator.
Background technology
Commutator is commonly called as commutator, is direct current generator, is commutated as electric current on A.C. series motor, in order to allow electricity
The part that motivation persistently rotates down.
Armature winding in traditional motor is formed using very thick copper cash with ripple winding coiling, and one end is arranged at winding company
In the groove of socket part, connected mode is powered by electrode so that coil heating is deformed and welded under the pressure effect of electrode, sternly
It is a kind of riveting effect that lattice, which are said,.There is connection defective tightness in this connected mode, the problem of being easily broken off coming off, cause product
Reliability is not strong, and service life is shorter.
Utility model content
The utility model embodiment technical problem to be solved is, for the commutator in present motor and copper cash
Defective tightness is connected, is easily broken, causes product reliability not strong, the shorter situation of service life, it is proposed that Yi Zhongxin
Type commutator.
In order to solve the above-mentioned technical problem, the utility model embodiment provides a kind of Novel commutator, the new commutation
Device is cylindrical structure, and side spaced set has copper sheet, mica sheet is provided between copper sheet, in one end of Novel commutator,
Copper sheet and mica sheet, which prolong, to be extended radially outwardly, formation winding connecting portion, and the outer surface of the copper sheet in winding connecting portion is provided with
One groove, depth of groove are less than the radius of outside copper cash.
Wherein, Novel commutator is provided with a connection through hole, and the axis for connecting through hole overlaps with Novel commutator axis.
Wherein, it is shoulder hole to connect through hole.
Wherein, winding connecting portion is vertical with the axis of Novel commutator.
Implement the utility model embodiment, have the advantages that：The groove of the winding connecting portion of this Novel commutator
More shallow than the groove of traditional commutator much outside copper cash is connected by the soldering lug of thawing with steering gear, and this connected mode connects
Connect closer, effectively increase the reliability and service life of product, and because groove is shallow a lot, when commutator rotates from
Mental and physical efforts decline a lot, while also save copper material.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the front view of existing commutator；
Fig. 2 is the left view of the converter in Fig. 1；
Fig. 3 is the left view of Novel commutator provided by the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1, Fig. 2 and Fig. 3 are referred to, Fig. 1 is the front view of existing commutator；Fig. 2 is a left side for the converter in Fig. 1
View；Fig. 3 is the left view of Novel commutator provided by the utility model.
Novel commutator includes：Copper sheet 1 and mica sheet 2.
Novel commutator is cylindrical structure, and side spaced set has copper sheet 1, mica sheet 2 is provided between copper sheet, is risen
To the effect of insulation.In one end of Novel commutator, copper sheet 1 and mica sheet 2, which prolong, to extend radially outwardly, and forms winding connecting portion
3, winding connecting portion 3 is vertical with the axis of Novel commutator.The outer surface of copper sheet 1 in winding connecting portion 3 be provided with one it is recessed
Groove, depth of groove are less than the radius of outside copper cash.Novel commutator is provided with a connection through hole (not indicating), connects through hole
Axis overlaps with Novel commutator axis, and connection through hole is shoulder hole.
Traditional commutator welding is powered by electrode causes coil heating to deform and weld under the pressure effect of electrode, strictly
Say it is a kind of riveting effect.Novel commutator provided by the utility model is first using argon arc welding between solder brazing coil and coil
Weld, then soldering lug is placed between inner coil and commutator, electrode makes coil heating melt soldering lug after being powered, in electricity
The lower soldering lug of pressure effect and coil of pole combine together.
Implement the utility model embodiment, have the advantages that：The groove of the winding connecting portion of this Novel commutator
More shallow than the groove of traditional commutator much outside copper cash is connected by the soldering lug of thawing with steering gear, and this connected mode connects
Connect closer, effectively increase the reliability and service life of product, and because groove is shallow a lot, when commutator rotates from
Mental and physical efforts decline a lot, while also save copper material.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
