Abstract
A commutator having circumferential hook segment type commutator bar comprises an insulating cylinder (11), a plurality of commutator bars (10) arranged on the surrounding surface of the cylinder and combined with the cylinder, wherein a hook segment (16) is arranged in the inner side of the combination of the commutator bar (10) and the cylinder (11), an insulating groove (12) arranged between the commutator bars (10) to exert the insulating function, the hook segment (16) stretches along the cylinder (11) in a circumferential direction in the inner side of the commutator bars. Compared with the prior art, the utility model can greatly reduce turning quantity of the commutator bars in the manufacturing process, thereby reducing the product cost.
Description
Affiliated technical field
The utility model relates to a kind of engine commutator, particularly relates to a kind of engine commutator with circumferential hook segment type commutator segment.
Background technology
Commutator is one of critical piece of motor, and it is by the commutator insulation cylindrical shell and be distributed in the cylindrical shell side face and constituted with some commutator segments of cylindrical shell strong bonded, passes through the insulation tank mutually insulated between each commutator segment.According to the different requirements to commutator, commutator segment can have different structures with the inboard of insulating cylinder body combination.Disclosed as CN2318732Y is a kind of commutator that commutator segment constituted (commutator) that is had hangnail by the inboard.In this hook sheet of grappling iron fixed pattern commutator segment generally be at blanking, roll into ring after, carry out slicing process at extrusion die, cut volume and form.Because the hook sheet on the commutator segment blank is with the parallel axes of rolling up ring and have groove, the rigidity at groove and non-groove position differs, make and when rolling into ring, can make anchor ring form polygon, as Figure 1-3, this polygon must be eliminated in the processing of the external diameter of commutator and forms a complete periphery.So, have enough rigidity in order to guarantee commutator segment, must strengthen the allowance of commutator segment, this has wasted valuable copper product undoubtedly, has improved product cost.
The content of utility model
The purpose of this utility model is exactly the above-mentioned deficiency that overcomes prior art, and a kind of novel engine commutator is provided, and reduces the allowance of commutator segment, reduces product cost.
Commutator of the present utility model, comprise insulating cylinder body and the some commutator segments that are distributed in the cylindrical shell side face and combine with cylindrical shell, the inboard that commutator segment combines with cylindrical shell has the hook sheet, between each commutator segment by the insulation tank mutually insulated, described hook sheet in the inboard of commutator segment along the circumferential stretching, extension of insulating cylinder body.
Because the inboard of the utility model commutator commutator segment has direction of extension and adds the identical hook sheet of coiling direction in man-hour with it, make the ring body that rolls have uniform periphery, can not form polygon along the circumferential direction, the allowance of turning be reduced greatly, thereby can reduce product cost.
Describe the utility model in detail with embodiment with reference to the accompanying drawings.

Each numbering expression in the accompanying drawing: 1 volume ring, 2 grooves, 3 commutator segments, 4 insulating cylinder body, 6 blanks, 7 grooves, 10 commutator segments, 11 insulating cylinder body, 12 insulation tanks, 16 hook sheets, 17 grooves.
Embodiment
Shown in Fig. 4-8, commutator of the present utility model comprises insulating cylinder body 11 and the some commutator segments 10 that are distributed in the cylindrical shell side face and combine with cylindrical shell, the inboard that commutator segment 10 combines with cylindrical shell 11 has hook sheet 16, between each commutator segment 10 by insulation tank 12 mutually insulateds, described hook sheet 16 in the inboard of commutator segment along the circumferential stretching, extension of described cylindrical shell 11.
At this, so-called " circumferentially " is meant the direction along circumference.
Because the commutator segment of the utility model commutator has the direction of extension identical with its processing coiling direction (promptly perpendicular with the axis of described cylindrical shell), make the ring body that rolls have uniform periphery, can not form polygon along the circumferential direction, the allowance of turning is reduced greatly, thereby can reduce product cost.
The utility model can also have following modification on the basis of the above:
1, described commutator segment has a plurality of hook sheets 16 that are arranged in parallel perpendicular to the axis of described insulating cylinder body 11.The quantity basis of hook sheet is decided the specific requirement of commutator, and when having higher binding strength between needs commutator segment and the insulating cylinder body, needed hook sheet quantity is just some more.
2, have groove 17 between the adjacent hook sheet 16, the cross section of groove 17 has from commutator segment towards cylindrical shell 11 the diminishing shape of axis, as shown in Figure 8.This structure can make has higher adhesion between commutator segment and the insulating cylinder body.
3, described commutator segment 10 has the cross section of arc in the direction perpendicular to insulating cylinder body 11 axis.As shown in Figure 4, the cross section of the commutator segment 10 in the utility model is complete arc, and its outside than prior art shown in Figure 3 is that cambered surface, inner face are that the commutator segment of non-cambered surface has better rigidity.
Described hook sheet can have various shape, as long as its direction of extension meets design of the present utility model.
Above-mentioned just illustrative to the description of utility model with reference to drawings and Examples, and do not constitute qualification to it.Obviously, on basis of the present utility model, can carry out many modification, but not break away from its essence.
