Description
Technical field
It the utility model is related to the armature and its manufacture method of starter direct current generator, more particularly to motor.
Background technology
Starter is by electromagnetic switch, direct current generator and transmission mechanism three parts composition, direct current generator again by drive end bearing bracket, after
End cap, brush holder, stator, armature are formed.Main core stamping, axle, commutator, the wire by being superimposed of armature（Winding conducting wire）Group
Into being respectively provided with slot for winding on existing armature of direct current motor lamination, its winding flute profile can be divided into semi-open slot（See Fig. 1）, standard-sized sheet
Mouth groove（See Fig. 2）Two kinds of forms.It is open groove that notch size, which is more than diameter of wire, and notch size is about the half of diameter of wire
It is semi-open slot.Groove inside conductor number be 2 for individual layer cable architecture, groove inside conductor number is 4 for double-deck cable architecture.Armature iron
The notch size of core and the number of plies of groove inside conductor have crucial effect to starter performance parameter.Notch size is bigger to air gap magnetic
The influence of field is bigger, reduces electric efficiency, notch is undersized also to influence electric efficiency, typically using semi-open slot as most
It is good.The wire that the wire number of plies participates in cutting magnetic lines is more, and the motor of double-deck cable architecture has that detent torque is big, motor
The advantages of output power.Semi-open slot armature core can only use insertion when wire enters in groove, so being only used for list
Layer line structure, technics comparing are simple.The armature of double-deck cable architecture can only use embedding inlay technique when wire enters in groove, so must select
With the armature core structure of open groove, after wire enters in the groove of open groove, in order to prevent armature wire in high rotating speed
It is thrown out of, it is necessary to carry out riveting point processing on iron core notch side using special instrument, technics comparing is complicated.
Because open channel chip influences motor gas-gap magnetic field, cause unloaded iron loss increase, make output torque less than normal.Half
Open slot lamination notch is small, small on air-gap field influence, reduces iron loss, but be only limited to split pulling shaping or stamping forming U
Shape wire winding 4, see Fig. 3, therefore be only used for the armature of single-layer winding structure of single, due to Double Layer Winding 5（Fig. 4）It is O shapes after shaping
Closing, the making of Double Layer Winding structure armature can not be met.Open channel chip is because notch opening is relatively large, generally
For the armature of Double Layer Winding structure, but because notch size is big, motor gas-gap magnetic field is have impact on, cause unloaded iron loss increase, together
When for ensure armature wire in high rotating speed be not thrown out of, it is necessary to be carried out using special instrument on iron core notch side at riveting point
Reason, influences production efficiency.
The structure of existing double-deck line armature can only use open slot core structure（Fig. 2）, first wound in iron core slot first
Dual-layer metal line such as Fig. 5, reuse riveting point frock 3 and riveting point processing such as Fig. 6 is carried out on iron core is cylindrical, armature notch is made by riveting point
Part narrows, and prevents armature wire when high speed rotates to be thrown out of.Because open slot armature influences big, armature slot on air-gap field
On mouth during riveting point, as press Stroke Control obtains bad, easily cause slot insulating paper and be damaged, cause iron core cell wall and wire short circuit,
Reliability of technology difference quality measurement is unstable, and scrappage height adds cost, reduces the competitive advantage of product commercially.
Utility model content
Technical problem to be solved in the utility model is in order to overcome the above-mentioned deficiencies of the prior art and provides a kind of rise
Motivation armature of direct current motor, it is set to facilitate in winding insertion iron core slot, and can improves the quality of armature and the performance of motor.
The utility model has also correspondingly provided the manufacture method of this kind of starter armature of direct current motor.
The technical scheme in the invention for solving the above technical problem is：Starter armature of direct current motor, it includes holding
Receive dual-layer metal line slot for winding armature core, slot for winding is open groove, it is characterised in that：The notch two of the open groove
Side sets the ear type position to two lateral outer lug of notch respectively, after completing dual-layer metal line winding in slot for winding, described two
The free end at ear type position can make open groove become half opening type groove to notch medial movement.
Preferably, the ear type position each side has one on same tooth, and it includes outside ear and outer
The breach towards groove formed in ear broadside and the tooth in groove of connection, breach include two-lines, and the one of a line
End is connected with one end of ear broadside, and the other end of a line is connected with another line, on the other end and groove of another line
Tooth side upper end is connected, and the outside of both sides ear and the center line of tooth are symmetrical, and the outside of outside and tooth is into openning shape.
The manufacture method of above-mentioned starter armature of direct current motor, first produce the iron core of open groove, the groove of open groove
Mouthful two sides set the ear type position to two lateral outer lug of notch respectively, then are embedded in bilayer in the open groove of iron core and lead
Line, then open groove is set to become half opening to notch medial movement the free end at ear type position under external pressure effect
Type groove, obtain starter armature of direct current motor.
Preferably, frock is also provided with, is pressed to the free end at ear type position on the inside of notch to make standard-sized sheet by frock
Mouth groove becomes half opening type groove, so processes faster, better quality.
The utility model has the advantage of：1st, it is more than diameter of wire in notch both sides design ear type position, notch size,
It will not be interfered when wire winding is in embedded armature slot, it is convenient to embedded；Can also be by shaping by notch both sides ear
Type position presses to notch, forms semi-open slot, is thus integrated with semi-open slot and the advantage both double-deck cable architecture, it not only goes
Except iron core and the hidden danger of wire short circuit, but also production efficiency is substantially increased, make motor that there is better performance, lower
Cost.
2nd, during armature manufacture of the present utility model, in two steps, winding is first embedded in electricity to armature rule process by the first step
In pivot groove, second step again integer into half opening shape.Therefore, the technique that wire winding makes and embedded holding tradition is ripe, is omitted
Riveting point handling process, only increase by one of integer process, product can is retained the function of semi-open slot and double-deck cable architecture
Advantage.It can solve the problems, such as existing rotor Double Layer Winding difficulty, and and can solves to influence motor gas-gap because opening groove width is present
Magnetic field, cause the problem of unloaded iron loss increase, so as to increase substantially production efficiency, and and can improves the performance of motor.
