Description
Technical field
This utility model relates to electric motors, a kind of portable sparkproof motor.
Background technology
The carbon brush of motor and the carbon brush of electromotor are referred to as again carbon brush for electric machine or motor brush, and the appearance of carbon brush for electric machine is somewhat like wiping
The rubber bar of pencil is such, top has wire draw, and volume varies.
And the Wound-rotor type carbon brush used on motor often occurs sparkling this situation, the most accidents caused when sparkling
Motor damage, therefore, the probability that reduction carbon brush sparkles extremely is necessary, and the Wound-rotor type carbon brush on motor can be burned with anger
The reason of flower is:
We are using wound-rotor motor carbon brush when, owing to, among long-term operation, constantly grinding carbon brush
Damaging, the face that comes in contact pressure uneven, carbon brush is inadequate or slip ring is non-round, and has oil droplet or other foreign material on bearing
Fall between slip ring and carbon brush etc. multiple situation, carbon brush all can be caused to give off sparks.
How to eliminate the submethod that carbon brush sparkles: we can use the light that the contact surface of carbon brush and slip ring is polished by fine sandpaper
Sliding, or the pressure of carbon brush is carried out suitable adjustment, and check whether slip ring is justified, if adhering to or being trapped in brush carrier
If dirty more, application brush cleaning or purge by compressed air.Carry out the safeguard procedures of slip ring and carbon brush, can have
The Wound-rotor type that reduces of effect clicks on the probability that carbon brush sparkles.

During situation, only spill spin block need to be unloaded from cover body rear end, then from cover body rear end, situation in cover body observed and carry out corresponding
Operation, thus relative to tradition enclosed shape cover body, the design of this cover body more hommization, easy to operate, save manpower.
Described brush device for cleaning includes cleaning with water post, handle and rubber strip, and described post of cleaning with water is slidably embedded by sliding tray
In electric brush cover, described post right-hand member of cleaning with water is provided with handle, and described in clean with water and on post, be uniformly fixed with rubber strip, described rubber
Adhesive tape is covered with cleans post with water.During work, operator can make to clean the post track along sliding tray in sliding tray with water and slide, and slide
The track of groove is positioned at the periphery of cover body brush, thus cleans post with water and can move around the brush periphery in cover body, and, clean post with water
During sliding, operator can hold handle, rotates cleaning post with water, and now rubber strip synchronizes to turn with cleaning post with water
Dynamic, the slip ring in cover body and brush can be cleaned with water during rotating by rubber strip.
Temperature sensor it is provided with on described each brush, thus when this utility model can understand brush in time with slip ring friction
Temperature, prevent friction temperature too high.
Beneficial effect:
(1) electric brush cover of the present utility model by cover body and can be turned on the spill spin block unloaded and constitutes, thus when need to check brush
The situations such as cover inner slide and brush, or when changing carbon-point, only spill spin block need to be unloaded from cover body rear end, then from cover body rear end
Situation in cover body is observed and carried out corresponding operating, thus relative to tradition enclosed shape cover body, the design of this cover body is more
Hommization, easy to operate, save manpower.
(2) design of this utility model brush device for cleaning makes when needing the dirty removing brush and slip ring, it is not necessary to by slip ring
Take out with brush, stretch into cover body clear up without turning on spill spin block staff, only need to slide and shake clear outside electric brush cover
Brush spine, cleaning effect of the present utility model is good, and operation is the most convenient, and reduces the possibility that on brush carrier, dirty is piled up, and subtracts
Lack the probability that electric spark occurs.
(3) when the design of this utility model temperature sensor makes this utility model can understand brush in time with slip ring friction
Temperature, prevent friction temperature too high, effectively ensured safe operation of the present utility model.
