Description
Technical field
A kind of wound-rotor motor sliding ring chamber ventilated device of the present invention, belongs to coiling electric motor manufacturing technology field.
Background technology
The rotor of winding motor is Wound-rotor type structure, and slip ring room is arranged on the inside of secondary axle stretch end Sliding bush, with stator
Isolated between chamber using simple seal, cause have passage between slip ring room and bore of stator, in actual motion, in bore of stator
Circulated air can form negative relative air-flow in the opening of division board, carbon dust caused by slip ring room carbon brush abrasion can be with the air-flow
Into in bore of stator, the end of phase-wound rotor is attached to, causes the attached electric discharge of carbon dust note, causes the electric discharge of rotor different parts broken
Pressure.
The content of the invention
The invention overcomes the deficiencies of the prior art, and provides one kind can solve to alter aeolian accumulation carbon, reduce rotor because
Attached discharge of carbon dust note causes the slip ring room ventilation unit of rotor fault.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is:A kind of wound-rotor motor sliding ring chamber ventilated
Device, including slip ring room, collector ring, brush holder, carbon brush, slip ring room are fixedly installed on coiling electric motor end cap, and machine shaft stretches into
Slip ring room, collector ring are set on machine shaft, and brush holder and carbon brush are provided with collector ring, cooling wind is provided with above slip ring room
Case, is provided with air inlet between slip ring room and cool wind box, slip ring room air inlet is provided with filter core, is provided with out below slip ring room
Air port, air exhauster is connected with air outlet, slip ring room chamber inner wall rear end is provided with sealing ring.
The sealing ring is labyrinth elastic wear-resistant seal ring.
The filter core is sponge filter core.
The present invention has the advantages that compared with prior art.
The 1st, air exhauster is set below slip ring room, it is ensured that negative pressure is produced in slip ring room, and the negative pressure of slip ring room is more than
The negative pressure of bore of stator, solve negative-pressure air-flow caused by draught head, and there is air-flow constantly to blow collector ring phase insulation
Sweep, reduce the carbon dust deposition of collector ring, ensure that the cleaning of rotor tip and bore of stator, improve the operation ring of collector ring
Border, reduce the labor intensity of plant maintenance personnel.
2nd, slip ring room chamber inner wall rear end is provided with labyrinth elastic wear-resistant seal ring, ensure that the carbon dust in slip ring room
Stator chamber will not be entered, ensure that bore of stator inner stator coil is attached without dust note with rotor tip, enhance Inside coil
Heat-sinking capability, reduce relative temperature rise during motor operation.
3rd, air inlet is provided with sponge filter core, it is ensured that the cleannes of air inlet, reduce external dust.
Brief description of the drawings
The present invention is described further below in conjunction with the accompanying drawings.

Sponge filter core is provided with, can be very good to reduce the entrance of outside motor dust, ensure the cleannes of the air inlet of slip ring room 6, in cunning
The rear inner wall of ring casing 6 is provided with sealing ring 7, it is ensured that caused carbon dust will not enter bore of stator 8 in slip ring room 6;In slip ring
The lower section of room 6 sets air exhauster 1, and air exhauster 1 can ensure that the negative pressure of slip ring room 6 is more than the negative pressure of bore of stator, thoroughly solve
Negative-pressure air-flow caused by draught head, dust note is attached caused by preventing the air-flow, ensure that the cleaning of rotor tip and bore of stator 8.
Window can also be provided with the air inlet and air outlet of described slip ring room 6, it is convenient that slip ring room inside is entered
Row observation.
Embodiments of the invention are explained in detail above in conjunction with accompanying drawing, but the present invention is not limited to above-mentioned implementation
Example, in those of ordinary skill in the art's possessed knowledge, can also make on the premise of present inventive concept is not departed from
