Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
Fig. 1 is the dedusting cooling structure schematic diagram that the present invention is used for synchronous motor bus ring carbon brush brush carrier；
Fig. 2 is the portion A enlarged drawing in Fig. 1；
Fig. 3 is brush carrier ontology schematic diagram in this structure.
Specific embodiment
Embodiment is as shown in Figure 1, Figure 2 and Figure 3, and dedusting of the present invention for synchronous motor bus ring carbon brush brush carrier cools down
Structure includes that the brush carrier ontology 2 being fixed on brush holder 1, dust suction air-guide branch pipe 3, dust suction air guide general pipeline 4, filter 5 and air draught are dynamic
Power source, the brush carrier ontology 2 21 periphery of carbon brush be equipped with dust-absorbing groove 22, the dust suction air-guide branch pipe 3 be set to the brush holder 1 and
Input terminal connects the dust-absorbing groove 22 of the brush carrier ontology 2, and the filter 5 is set to 1 side of brush holder, and the dust suction air guide is total
Pipe 4 connects 3 output end of dust suction air-guide branch pipe and 5 input terminal of filter, and it is defeated that the air draught power source connects the filter 5
Outlet.
Preferably, the air draught power source is provided at the vacuum pump 61 of the brush holder side.
Preferably, the air draught power source is the negative pressure catheter 62 for being connected to motor cavity, and the negative pressure catheter 62 connects institute
State 5 output end of filter.
Preferably, this structure further includes switching valve 7, and the vacuum that the air draught power source is provided at 1 side of brush holder is taken out
Air pump 61 and the negative pressure catheter 62 for being connected to motor cavity, the negative pressure catheter 62 connect 5 output end of filter, the switching
Valve 7 is separately connected 5 output end of filter, vacuum pump 61 and is connected with negative pressure catheter 62 with 5 output end of switch filtering device

This structure can voluntarily absorb carbon dust, while can reduce carbon brush fuel factor, to using the same of bus ring structure
It walks motor or even can be applicable in using the direct current generator of commutator structure.
Carbon brush is fixed by brush carrier ontology in this structure, and brush carrier body peripheral has a circle air draught slot, by the air draught slot to carbon
The carbon dust that brushing chips away is collected, and each brush carrier ontology air draught slot draws by the dust suction air-guide branch pipe of insulation and passes through insulation
Dust suction air guide general pipeline convergence imported into the air inlet of filter, and filter air entry connects air draught power source.In this structure
Air draught power source can be there are two types of source, and one is make full use of high-speed motor inner cavity with this feature of negative pressure, i.e., in motor
Chamber atmospheric pressure is smaller to form certain vacuum degree than external, and outside air can flow backward toward motor cavity, by big in motor
It covers and sets ventilation opening and introduced the negative pressure using insulation negative pressure catheter, acting not only as air draught power source can also be with active balance
Exocoel atmospheric pressure in motor, this point are very valuable to end cover type sliding bearing bush synchronous motor, because negative pressure can cause axis
Watt lubricating oil penetrates into motor cavity, and pollution winding table face rings insulation；Another kind is to be mounted directly a vacuum pump conduct
Air draught power source.Two kinds of air draught power sources can coexist simultaneously, be switched over by switch valve.Both air draught power sources are logical
The dust suction air-guide branch pipe and dust suction air guide general pipeline for crossing filter and insulation are connected to brush carrier body perimeter air draught slot, eventually as
The suction of carbon brush powder is absorbed, to not only be able to achieve from the function of removing carbon dust, but also brush carrier body surface and carbon brush and collection
Electric slip ring rubbing surface is because there is free airflow kinetic energy to reach the effect of taking away thermal energy, so that realizing reduces carbon brush surface heating effects
It influences, it is ensured that the normal reliable of synchronous motor is run.
