Abstract
The utility model relates to one kind rise reuse coiling electric motor rotor dust board structure, it by: rotor dust board, stator dust board, carbon block, brush-holding device, collector ring, end cap, Qu Lu, fan piece, axis are constituted.Rotor dust board is mounted on an axle, and can be rotated with axis, and stator dust board is fixed on end cap, brush-holding device is fixed on end cap, carbon block is housed, collector ring is on axis on brush-holding device, it is equipped with Qu Lu between rotor dust board and stator dust board, multiple fan pieces are housed on rotor dust board.The product structure is simple, design is reasonable, since rotor dust board is labyrinth gap cooperation, it increases carbon dust and enters the intracavitary path of rotor, and increase flabellum on rotor dust board, can effectively purge carbon dust, prevent carbon dust from entering rotor dust board Qu Lu, to prevent carbon dust to be adsorbed on Stator and Rotor Windings, so that insulation system failure is led to turn-to-turn, improve the quality of motor.
Description
Technical field
It is risen the utility model relates to one kind and reuses coiling electric motor rotor dust board structure, be electric to reuse wound rotor is played
The improvement of the stator and rotor dust board sealing structure of machine.
Background technique
Currently, the rotor dust board of the lifting of YZR series and metallurgical winding rotor motor rotates with the axis, rotor dust board and
The unilateral minimum gap 2mm of stator dust board, rotor are powered by collector ring and brush-holding device rotating contact, and carbon brush friction will necessarily
Carbon dust is generated, carbon dust enters rotor inner cavity by rotor gap and is adsorbed on Stator and Rotor Windings, and insulation is caused to reduce, and influences
The heat dissipation effect of rotor causes motor turn-to-turn.
Summary of the invention
The purpose of the utility model is to overcome disadvantages mentioned above, and it is hardened to provide a kind of reuse coiling electric motor rotor dust-break
Structure, carbon block and collector ring relative friction when it mainly solves the work of existing motor on brush-holding device, has carbon dust and flies
In the cavity, part carbon dust can be entered by the gap of 2mm among rotor dust board machine cavity be attached to rotor around
Group surface, prevents motor radiating, failure of insulation is led to problems such as to make motor turn-to-turn.The purpose of this utility model is realized in
, one kind rise reuse coiling electric motor rotor dust board structure by: rotor dust board, stator dust board, carbon block, brush-holding device,
Collector ring, end cap, Qu Lu, fan piece, axis are constituted.Rotor dust board is mounted on an axle, and can be rotated with axis, and stator dust board is fixed
On end cap, brush-holding device is fixed on end cap, and carbon block is housed on brush-holding device, collector ring on the axis, rotor dust board with
It is equipped with Qu Lu between stator dust board, multiple fan pieces are housed on rotor dust board.The product structure is simple, and design is reasonable, by
It is labyrinth gap cooperation in rotor dust board, increases carbon dust and enter the intracavitary path of rotor, and in rotor dust-break
Flabellum is increased on plate, can effectively purge carbon dust, prevents carbon dust from entering rotor dust board Qu Lu, so that carbon dust be prevented to inhale
It is attached on Stator and Rotor Windings, so that insulation system failure is led to turn-to-turn, improve the quality of motor.

1-rotor dust board 2-stator dust board 3-carbon block, 4-brush-holding device, 5-collector ring
6-7-bent road of end cap, 8-fan, 9-axis of piece.
Specific embodiment
The most preferred embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings, one kind, which rises, reuses coiling electric motor rotor gear
The hardened structure of dirt is by rotor dust board 1, stator dust board 2, carbon block 3, brush-holding device 4, collector ring 5, end cap 6, Qu Lu 7, fan piece
8, axis 9 is constituted.Rotor dust board 1 is mounted on axis 9, can be rotated with axis 9, and stator dust board 2 is fixed on end cap 6, brush carrier dress
It sets 4 to be fixed on end cap 6, carbon block 3 is housed on brush-holding device 4, collector ring 5 is on axis 9, rotor dust board 1 and stator dust-break
It is equipped with bent road 7 between plate 2, multiple fan pieces 8 are housed on rotor dust board 1.
Working principle, carbon block 3 and 5 relative friction of collector ring when motor works on brush-holding device 4 generate carbon dust, have carbon
Powder is flown in the cavity, and rotor increases carbon dust and enter the intracorporal distance of rotor chamber, and in rotor using bent road design
Fan piece 8 is increased on dust board 1, plays the role of purging carbon dust, carbon dust is prevented to enter in rotor cavity.
