Description
Technical field
The utility model is related to a kind of reinforced reversers for motor.
Background technology
Commutator is the critical piece in motor, and commutator mainly by phenolic moulding powder main body and is arranged in phenolic moulding powder main body at present
Periphery copper bar commutator segment group into.But current this structure is because of the limitation of the heatproof and moulding process of phenolic moulding powder, often matter
The consistency of amount cannot obtain basic guarantee, in copper bar than on heavier or bigger outer diameter commutator, since centrifugal force is
Proportional with quality and outer diameter, quality and outer diameter are bigger, then centrifugal force is bigger, and the mechanical strength of phenolic moulding powder can not just expire
The requirement of sufficient higher performance motor, copper bar surface surface segment difference when running at high speed will exceed the requirement of standard, cause motor
Spark is so as to influence the service life of motor.
Utility model content
Above-mentioned to solve the problems, such as, the purpose of this utility model is to provide a kind of reinforcement type commutations for motor
Device.The reinforced reverser for motor, simple in structure, commutator each section is firmly combined with, and effectively prevents commutator
Problem of Cracking improves the mechanical performance and stability of commutator, extends its service life.
In order to achieve the above objectives, the technical solution of the utility model is：
A kind of reinforced reverser for motor, including：
Insulating sleeve：In a ring, insulating sleeve inner wall is provided with a reaming；
Commutator segment：Around insulating sleeve periphery is set to, commutator segment both ends are respectively arranged with mounting groove, connect with insulating sleeve
It connects, is provided in mounting groove by commutator segment and the fixed reinforcing ring of insulating sleeve, is filled between the reinforcing ring and commutator segment
Buffer substrate tablet, the buffer substrate tablet are c-type, are provided with crotch above commutator segment one end, the commutator segment is additionally provided with several apertures；
Mica sheet：It is set between adjacent commutator segment, mica sheet is provided with a recessed portion close to the side of insulating sleeve, separately
Isolation recesses are provided at one exterior angle of side, the isolation recesses are provided with chamfered section.The commutator segment structure setting has installation
Slot makes commutator segment connect fastening with insulating sleeve, the aperture on commutator segment, increases the contact surface of commutator segment and insulating sleeve
Product, prevents the generation of commutator segment film dancing and film flying phenomenon, filled with buffer substrate tablet between reinforcing ring and commutator segment, can ensure in work
The stability of commutator in work is provided with recessed portion on mica sheet, also enhances the binding force between mica sheet and insulating sleeve,
Improve the quality of commutator product.
Further, the insulating sleeve is made of bakelite powder material.
Further, the aperture is round or regular hexagon.
Further, the axis of the reinforcing ring and commutator are coaxial.
Further, the reinforcing ring is made of the metal or ceramic material for being coated with insulating layer.
The beneficial effects of the utility model are：
A kind of reinforced reverser for motor described in the utility model, simple in structure, commutator each section combines
Securely, commutator problem of Cracking is effectively prevented, the mechanical performance and stability of commutator is improved, extends its service life.
