Description
Technical field
The present invention relates to a kind of motor fields, especially minitype speed reducing motor.
Background technology
Decelerating motor refers to the conglomerate of speed reducer and motor (motor).This conglomerate is usually alternatively referred to as gear motor
Or gear motor.Usually by the speed reducer factory of profession integrate and assembles the rear complete supply of material.Decelerating motor extensive use
In steel industry, machinery industry etc..The use of the advantages of decelerating motor is to simplify design, saving space.And in decelerating motor, it uses
Be substantially direct current generator, and direct current generator is compared with other kinds of motor, have it is small, efficient, simple in structure,
The advantages that copper consumption is few, is the main Types of low powered DC motor.In order to further increase the reliable of DC Motor Drives
Property, that is, the service life for improving direct current generator is needed, the existing method for improving direct current generator is generally using the quick electricity that pressurizes on commutator
It hinders, power-up appearance etc. on increase motor torsion, end cap, the direct current generator first having generally all is welded with zinc oxide pressure-sensitive, is not changing electricity
Increase torsion on the case where machine performance and necessarily will increase the electric current of motor, however increases electric current and do not need higher electric cost then not
Job requirement can be met, and in the case of big torsion, the fever of motor also can when the river rises the boat goes up, and the temperature overheated can influence electricity
The normal work of machine, causes torsion to decline therewith, it is difficult to meet production requirement, and power up the method for appearance on end cap in such electricity
It also is difficult to realize on machine.
Invention content
The technical problem to be solved by the present invention is to：A kind of starting smooth, long-life and simple in structure small-sized or micro- is provided
Type motor.
The solution that the present invention solves its technical problem is：A kind of long-life minitype speed reducing motor, including stator and turn
Son and end cap, the rotor includes shaft, the magnetizer that is fixed in shaft and commutator, the pressure-sensitive electricity being welded on commutator
The winding for hindering, being wound on magnetizer, winding are electrically connected with commutator, the winding of magnetizer and winding thereon and commutator edge
Shaft is axially arranged side by side；Stator includes shell, is fixed to the magnetic shoe of shell inner surface and in the indoor bearing of bearing；End cap packet
It includes plate in iron covering plate, the plastics being riveted on iron covering plate, fill the brush handle assembly in plate in the plastic, brush handle assembly includes carbon brush holder
With on carbon brush holder carbon brush and the amortisseur bar that is attached on carbon brush holder, the front end of the shell be equipped with double reduction case, institute
It states shaft and engages connection with double reduction case.The commutator material using AgCuNi, what is welded on commutator is strontium titanates
It is pressure-sensitive.
As a further improvement of the above technical scheme, the brush carrier thickness of the brush handle assembly is 0.12mm.
The beneficial effects of the invention are as follows：The present invention materially increases deceleration by the adjustment to the equipment that commutates
The service life of motor.
Description of the drawings
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described.Obviously, described attached drawing is a part of the embodiment of the present invention, rather than is all implemented
Example, those skilled in the art without creative efforts, can also be obtained according to these attached drawings other designs
Scheme and attached drawing.
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode
The technique effect of the design of the present invention, concrete structure and generation is carried out below with reference to embodiment and attached drawing clear
Chu is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright a part of the embodiment, rather than whole embodiments, based on the embodiment of the present invention, those skilled in the art are not being paid
The other embodiment obtained under the premise of creative work, belongs to the scope of protection of the invention.In addition, be previously mentioned in text
All connection/connection relations not singly refer to component and directly connect, and refer to that can be added deduct according to specific implementation situation by adding
Few couple auxiliary, to form more preferably coupling structure.Each technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
Referring to Fig.1, a kind of long-life minitype speed reducing motor, including stator and rotor and end cap, the rotor include turning
Axis 1, the magnetizer 2 being fixed in shaft and commutator 3, the varistor 4 being welded on commutator, be wound on magnetizer around
Group 5, winding 5 is electrically connected with commutator 3, and the winding 5 of magnetizer 2 and winding thereon is axially set with commutator 3 along shaft side by side
It sets；Stator includes shell 6, is fixed to the magnetic shoe 7 of 6 inner surface of shell and in the indoor bearing of bearing 8；End cap include iron covering plate 9,
It is riveted on plate 10 in the plastics on iron covering plate, fills the brush handle assembly in plate in the plastic, brush handle assembly includes carbon brush holder 11 and dress
