Description
Technical field
The utility model is related to a kind of Hooked reversers with surface groove bushing.
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 hooks with surface groove bushing
Type commutator.The Hooked reverser with surface groove bushing, simple in structure, commutator each section is firmly combined with, effectively
Bushing autobiography is prevented, commutator problem of Cracking 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 Hooked reverser with surface groove bushing, including：
Insulating sleeve：In a ring, buckle protrusion is provided on insulating sleeve；
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, is provided with crotch above one end, and the commutator segment center is further opened with a recessed portion, and with the buckle on insulating sleeve
Protrusion matches；
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 at the inner wall of insulating sleeve, the sleeve outer surface is provided with several grooves, described
Groove is rectangular.The commutator segment structure setting has mounting groove and recessed portion, cooperates with buckle protrusion, increases commutator segment
With the contact area of insulating sleeve, the generation of commutator segment film dancing and film flying phenomenon is prevented, sleeve outer surface setting is fluted, makes lining
There is higher conjugation between set and commutator ontology.
Further, the sleeve outer surface is also evenly arranged with cannelure in a circumferential direction, and the cannelure is arc
Shape slot.Increase friction, make the combination between bushing and commutator more secured.
Further, the head width of the buckle protrusion is more than root width.
Further, it is additionally provided with commutator segment and the fixed reinforcing ring of insulating sleeve in the mounting groove.Further plus
The binding force of strong commutator segment and insulating sleeve.
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 Hooked reverser with surface groove bushing described in the utility model, simple in structure, each portion of commutator
Divide and be firmly combined with, effectively prevent bushing autobiography, commutator problem of Cracking improves the mechanical performance of commutator, extends its use
Service life.
