Description
Technical field
The utility model is related to a kind of reinforcement type Hooked reversers with copper bush.
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 hooks with copper bush
Type commutator.The reinforcement type Hooked reverser with copper bush, simple in structure, commutator each section is firmly combined with, effectively
Commutator problem of Cracking is prevented, improves the mechanical performance of commutator, extends its service life.
In order to achieve the above objectives, the technical solution of the utility model is：
A kind of reinforcement type Hooked reverser with copper bush, including：
Insulating sleeve：In a ring, insulating sleeve inner wall both ends offer reaming and reaming；
Commutator segment：Around insulating sleeve periphery is set to, commutator segment both ends are respectively arranged with mounting groove, consolidate with insulating sleeve
Fixed connection, one end top are provided with crotch, and the commutator segment center is further opened with a square through hole；
Mica sheet：It is set between adjacent commutator segment, mica sheet one end is provided with protrusion, and the protrusion side is provided with down
Corner；
Bushing：In a ring, it is set between upper reaming and the reaming of insulating sleeve.The commutator segment structure setting has peace
Tankage and through-hole increase the contact area of commutator segment and insulating sleeve, prevent the generation of commutator segment film dancing and film flying phenomenon, carry
The quality of high commutator product.
Further, the sleeve outer surface is also evenly arranged with cannelure in a circumferential direction, and the cannelure is arc
Shape slot.
Further, it is additionally provided with commutator segment and the fixed reinforcing ring of insulating sleeve in the mounting groove.
