Ring the projected life of motor, it is therefore desirable to design the more excellent commutator of a structure to meet the requirement of client.
The content of the invention
In order to solve the above technical problems, the utility model provides a kind of improved commutator segment, prevent commutator segment tail end and float
The problem of row, improves the mechanical performance of commutator, offset between piece when reducing operating.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：A kind of improved commutator segment, including expose in electricity
The fixing end in working end and embedded bakelite main body outside wooden main body, it is characterised in that：The middle part of the fixing end is provided with
Fixing end is separated into several fixation pin splits, institute isolated from one another by the open slot for filling phenolic moulding powder, the open slot
State several fix pin splits with the working end integrally connected, and two therein fixed pin splits form fixation respectively
Two ends at end.
In one preferred embodiment of the utility model, further include that the middle part of the fixing end is provided with described in two
Open slot.
In one preferred embodiment of the utility model, the cross section of the open slot is further included for trapezium structure, ladder
The elongated base plate of shape structure is arranged on bottom land.
In one preferred embodiment of the utility model, the cross section for further including the working end is " L " character form structure.
To reach above-mentioned purpose, another technical scheme of the present utility model is as follows：A kind of commutator, including bushing, setting
Bakelite main body on the outside of bushing, the commutator segment for being arranged in bakelite main body periphery, it is characterised in that：The commutator segment will for right
The commutator segment described in any one of 1-4 is sought, it is mutually embedding by open slot and fixed pin split between the bakelite main body and commutator segment
Set is set.
The beneficial effects of the utility model are：
One, the commutator segment of optimizing structure design of the present utility model can prevent the problem of its tail end floating mat, and raising is changed
To the mechanical performance of device, offset between piece when operating is reduced, the commutator using the commutator segment is not using the premise of reinforcing ring
It is lower just to obtain good tensile strength；
Secondly, the small muscle of the working end due to commutator segment and fixing end, fixed pin be connected as a single entity, significantly increase commutation
Adhesion between piece and bakelite main body, so as to increase the mechanical strength of commutator；
Thirdly, the setting of open slot, increased the contact area of commutator segment and bakelite main body, enhance bakelite main body exchange
To the pulling force of piece.
Wherein：2- working ends, 4- fixing ends, 6- open slots, 8- fixes pin split, the small muscle of 10-, 12- bakelite main bodys, 14-
Bushing, 16- commutator segments.
