Abstract

The utility model discloses a novel collecting ring which consists of a slip ring and a brush rocker, wherein the brush rocker comprises a brush box and a brush rod, and the slip ring comprises a conducting rod and a mold pressing structure. Because the mold pressing structure is adopted and insulating parts among phases are transited by using fillets, carbon is not easily deposited on the surface of the novel collecting ring structure, the common fault of the 225 collecting ring for fire-striking of an electric brush because of the carbon deposit is greatly improved; and the collecting ring structure is fixed by using the constant force spring type and the spring force is adjusted to 200 CN/cm<2>, thereby abrasion loss of the electric brush is greatly reduced and better effect is achieved.

Description

Novel collector ring structure

Technical field

The utility model relates to a kind of novel collector ring structure.

Background technology

Slip ring structure in existing 225 collector rings is because the spaced apart too small (seeing accompanying drawing 1) between the three-phase, adopt board-like insulation between the three-phase, this kind structure is owing to exist corner angle, make the easy carbon distribution of slip ring, and cause behind the carbon distribution between phase and phase that creepage distance is too small, cause the brush sparking, thereby cause electrical machinery life to shorten; Brush adopts the end finger formula to fix, and wear of brush is too fast; The ring spacing of 225 collector rings is 55mm, because ring spacing is too small, behind the carbon distribution, makes its creepage distance shorten on the insulation board between phase and phase, causes phase fault, causes the collector ring failure rate too high; The fixing end finger formula that adopts of brush in 225 collector rings, when the end finger exercise not harmony, impel brush to produce the vibratility spark, make wear of brush serious, well-known, the pressure of brush and the wearing and tearing of brush are closely related, the selection of brush pressure will suit, the too high or too low wearing and tearing that all can quicken brush in the life-span of shortening motor, descend the serviceability of brush.

The utility model content

The purpose of this utility model provides and a kind ofly can guarantee that motor normally moves, and makes the collector ring structure that generator can safe and stable operation.

The technical scheme that the utility model is adopted for achieving the above object is: a kind of novel collector ring structure, described novel collector ring is made up of slip ring and brush holder.

Described brush holder comprises brush box and brush holder support.

Described slip ring comprises conducting rod and compression-molded structures.

Be provided with brush in the described brush box.

Described brush adopts the constant force spring formula to fix.

The novel collector ring structure of the utility model compared with prior art has following advantage:

1, the novel collector ring structure of the utility model is owing to adopt compression-molded structures, and insulated part between phase and phase adopts round-corner transition, makes its surface be not easy carbon distribution, has improved 225 collector rings widely owing to carbon distribution, and causes the common fault of brush sparking;

2, the ring spacing of 225 collector rings is 55mm, because ring spacing is too small, on the insulation board between phase and phase behind the carbon distribution, make its creepage distance shorten, cause phase fault, cause the collector ring failure rate too high, and in the slip ring structural design of the utility model collector ring structure, after ring spacing was adjusted into 94mm, this type of fault occurred again;

3, in the design of the utility model collector ring, adopt the constant force spring formula to fix, and spring force is transferred to 200CN/cm ², greatly reducing the wear extent of brush, effect is better.

Embodiment

As Fig. 4, Fig. 5 and shown in Figure 6, this novel collector ring structure is made up of brush holder 1 and slip ring 2, and this brush holder 1 part comprises brush holder support 11 and brush box 12, is provided with brush 13 in this brush box 12; Slip ring 2 parts comprise conducting rod 21 and compression-molded structures 22, novel collector ring structure slip ring 2 of the present utility model adopts the mold pressing form, insulated part between phase and phase adopts round-corner transition owing to whole, thereby makes its surface be not easy carbon distribution, has improved the fail safe of slip ring operation widely; In this novel collector ring structural design, adopt the constant force spring formula to fix, and spring force is transferred to 200CN/cm ², facts have proved that greatly reduce the wear extent of brush, effect is better.
