Description
Technical field
The present invention relates to electric motors, specifically a kind of sparkproof alternating current generator.
Background technology
The carbon brush of motor and the carbon brush of generator are referred to as carbon brush for electric machine or motor brush again, and the appearance of carbon brush for electric machine is a little
As wiping the rubber item of pencil, there are conducting wire extraction, volume to vary on top.
And the Wound-rotor type carbon brush used on motor often will appear the such case that sparkles, and be easy to cause when sparkling
Accident burns motor, and therefore, reducing the probability that sparkles of carbon brush, very it is necessary to and the Wound-rotor type carbon brush on motor can emit
The reason of spark is：
We are when using wound-rotor motor carbon brush, due among long-term operation, constantly being ground to carbon brush
Damage, be in contact face is uneven, pressure of carbon brush not enough either slip ring is non-round and bearing on there is oil droplet or other sundries to fall
To a variety of situations between slip ring and carbon brush etc., can all carbon brush be caused to give off sparks.
How submethod that carbon brush sparkle is eliminated：We can use fine sandpaper that the contact surface of carbon brush and slip ring is polished
It is more smooth, or adjustment appropriate is carried out to the pressure of carbon brush, and check whether slip ring is justified, if adherency or being trapped in brush carrier
If incrustation in is more, clears away or use compressed air purging using brush.The safeguard procedures of slip ring and carbon brush are carried out, can be had
The reduction Wound-rotor type of effect clicks the probability that carbon brush sparkles.
Invention content
In order to make up for the deficiencies of the prior art, the present invention provides a kind of sparkproof alternating current generator, brush can be reduced
The probability to sparkle, the effective safety for ensureing motor.
The technical solution adopted by the present invention to solve the technical problems is：A kind of sparkproof alternating current generator, including motor casing,
Stator, rotor, electric machine main shaft and fan；The internal structure and operation principle of motor are neither the innovations of this case, herein not
It repeats again；The invention also includes electric brush cover, insulating sleeve, slip ring, brush holder support, brush, dedusting capsule, temperature sensors and by calming the anger
Cylinder；The slip ring is connected on insulating sleeve, and the insulating sleeve is connected on electric machine main shaft, and the brush holder support is connected in
Electric brush cover inside upper part, on the brush holder support equidistantly uniformly installation there are three brush, the dedusting capsule with to press air cylinder equal
Positioned at electric brush cover top.
The brush includes brush carrier, connecting terminal and a pair of of carbon-point, and the brush carrier includes upper brush carrier and left and right brush carrier,
The upper brush carrier is connected on brush holder support, and the upper brush carrier upper end is provided with connecting terminal, and a pair of of carbon-point is connected
In the brush carrier of left and right, and a pair of of carbon-point is symmetrically positioned in slip ring both upper ends thereof and is in contact with slip ring both upper ends thereof；
The pressing number of cylinders is six, and described six are one group by air cylinder each two, and described every group is pressed air cylinder
Each brush both ends are respectively symmetrically mounted on, and are respectively connected on electric brush cover by air cylinder one end, the other end and carbon-point upper surface
It is in contact；When work, when carbon-point abrasion is excessive, carbon-point lower face contact with slip ring injustice, pressure it is inadequate when, then by air cylinder work
Make, pressure is applied to carbon-point.
The electric brush cover includes cover body and spill spin block, and setting is and described each there are two dedusting hole on the cover body
Dedusting hole is located above the middle part of two neighboring brush；The cover body rear end is provided with threaded hole, is set on the spill spin block
It is equipped with external screw thread, the spill spin block is threaded in cover body rear end；Under original state, spill spin block is mounted on cover body rear end, when
Situations such as needing to check electric brush cover inner slide and brush, or when replacement carbon-point, spill spin block need to only be unloaded from cover body rear end, then
From being carried out to situation in cover body from cover body rear end and corresponding operating is carried out, to relative to traditional enclosed shape cover body, this cover body
Design more hommization, it is easy to operate, save manpower.
There are two the dedusting capsules, and dedusting capsule is the cavity structure of rubber material, each dedusting capsule lower end difference
It is fixedly connected with two dedusting holes, each dedusting capsule upper end is provided with snorkel, and pipe is threaded on the snorkel
Lid；When incrustation is more on brush carrier, electric spark is easily caused, can be removed incrustation by the method for compressed air purging at this time,
Therefore, operating personnel can periodically squeeze dedusting capsule, and the air squeezed out by dedusting capsule is removed the incrustation on brush carrier, and
It, then can be by unscrewing pipe lid when the extremely difficult removal of the incrustation on brush carrier so that dedusting capsule connects extraneous air pressure by snorkel
Contracting machine, the air compressed by air compressor carry out strength purging to the incrustation on brush carrier, to present invention removal brush carrier product
When dirty, without taking out brush carrier, without spill spin block is unscrewed, dedusting capsule only need to be squeezed outside electric brush cover, is difficult to when encountering
The incrustation of cleaning can be also connected by dedusting capsule with extraneous air compressor, to which cleaning effect is good, and be operated very just
Victory, and the possibility that incrustation is accumulated on brush carrier is reduced, reduce the probability of electric spark generation.
Be both provided with temperature sensor on the left and right brush carrier of each brush, to the present invention can understand in time brush with
Temperature when slip ring rubs, prevents friction temperature excessively high.
Advantageous effect：
(1) electric brush cover of the invention by cover body and can unscrew the spill spin block unloaded and constitute, to sliding in electric brush cover when needing to check
Situations such as block and brush, or when replacement carbon-point, spill spin block need to only be unloaded from cover body rear end, then from cover body rear end in cover body
Corresponding operating is observed and carried out to situation, to relative to traditional enclosed shape cover body, the design more hommization of this cover body, behaviour
Facilitate, saves manpower.
(2) present invention is designed with dedusting capsule, when needing to remove the incrustation of brush carrier, without taking out brush carrier, without stubborn
Open spill spin block, only need to squeeze dedusting capsule outside electric brush cover, when encountering the incrustation for being difficult to clear up, also can by dedusting capsule with outside
Portion's air compressor is connected, to which cleaning effect is good, and operate it is very convenient, and reduce that incrustation on brush carrier accumulates can
Can, reduce the probability of electric spark generation.
(3) present invention by the design of air cylinder to contact when brush with slip ring injustice, pressure it is inadequate when, can be by pressing
The adjustment of pressure is realized in the contraction of air cylinder, easy to use.
(4) design of temperature sensor of the present invention allows the invention to understand temperature when brush rubs with slip ring in time
Degree, prevents friction temperature excessively high, has effectively ensured the safe operation of the present invention.
