Description
Technical field
The present invention relates to electric motors, specifically a kind of portable sparkproof motor.
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 bar of pencil, there is wire extraction on top, volume varies.
And the such case that sparkles often occurs in the Wound-rotor type carbon brush used on motor, easily trigger when sparkling
Accident burns motor, and therefore, reducing the probability that carbon brush sparkles extremely is necessary, and the Wound-rotor type carbon brush on motor can emit
The reason for spark is：
We are when using wound-rotor motor carbon brush, due among long-term operation, constantly entering to carbon brush
Row abrasion, it is in contact face injustice, the pressure of carbon brush not enough or slip ring is non-round, and has oil droplet or other miscellaneous on bearing
Thing falls between slip ring and carbon brush etc. a variety of situations, can all cause carbon brush 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 appropriate adjustment is carried out to the pressure of carbon brush, and check whether slip ring is justified, if adhesion 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 on the probability that carbon brush sparkles.
The content of the invention
In order to make up the deficiencies in the prior art, the invention provides a kind of portable sparkproof motor, and it can reduce
The probability of sparking of brushes flower, the effective safety for ensureing motor.
The technical solution adopted for the present invention to solve the technical problems is：A kind of portable sparkproof motor, including electricity
Casing, stator, rotor, electric machine main shaft and fan；The internal structure and operation principle of motor are neither the innovations of this case,
This is repeated no more；Present invention additionally comprises electric brush cover, insulating sleeve, slip ring, brush holder support, brush, brush device for cleaning and temperature sensor；Institute
The slip ring stated is connected on insulating sleeve, and described insulating sleeve is connected on electric machine main shaft, and described brush holder support is connected in brush
Cover inside upper part, three brushes are uniformly equidistantly installed on described brush holder support, described brush device for cleaning is located at electric brush cover top.
Described electric brush cover includes cover body, spill spin block and sliding groove, and described cover body rear and front end face is provided with arc
Sliding groove；Described cover body rear end is provided with screwed hole, and external screw thread, described spill spin block screw thread are provided with described spill spin block
It is connected to cover body rear end；Under original state, spill spin block is arranged on cover body rear end, when needing to check slip ring and brush etc. in electric brush cover
During situation, spill spin block need to only be unloaded from cover body rear end, then from being carried out from cover body rear end to situation in cover body and carried out corresponding
Operation, so as to which relative to traditional enclosed shape cover body, the design more hommization of this cover body is easy to operate, saves manpower.
Described brush device for cleaning includes cleaning post, handle and rubber strip with water, and described to clean post with water slidable by sliding groove
In embedded electric brush cover, described post right-hand member of cleaning with water is provided with handle, and described clean with water is uniformly fixed with rubber strip on post, described
Rubber strip, which is covered with, cleans post with water.During work, operating personnel can make to clean with water post in the slip of the track of sliding groove interior edge sliding groove, and slide
The track of groove is located at the periphery of brush in cover body, can be around the brush periphery motion in cover body so as to clean post with water, also, cleans post with water and exist
During slip, operating personnel can hold handle, be rotated to cleaning post with water, and now rubber strip synchronization rotates with post is cleaned with water,
Rubber strip can be cleaned with water during rotating to the slip ring in cover body and brush.
Temperature sensor is provided with each brush, so as to when the present invention, which can understand brush in time, to be rubbed with slip ring
Temperature, prevent that friction temperature is too high.
Beneficial effect：
(1) electric brush cover of the invention by cover body and can turn on the spill spin block unloaded and form, so as to when needing to check electric brush cover
Situations such as inner slide and brush, or during replacing carbon-point, spill spin block need to only be unloaded from cover body rear end, then from cover body rear end to cover
Internal situation is observed and carries out corresponding operating, so as to relative to traditional enclosed shape cover body, the design more human nature of this cover body
Change, it is easy to operate, save manpower.
(2) design of brush device for cleaning of the present invention causes when needing the incrustation of discharging brush and slip ring, without by slip ring and
Brush takes out, and is cleared up without turning on spill spin block and stretching into cover body with human hand, need to only be slided outside electric brush cover and shake is cleaned with water
Post, cleaning effect of the invention is good, and operates possibility that is very convenient, and reducing incrustation accumulation on brush carrier, reduces electric fire
The probability that flower occurs.
(3) design of temperature sensor of the present invention allows the invention to understand temperature when brush rubs with slip ring in time
Degree, prevents that friction temperature is too high, has effectively ensured the safe operation of the present invention.
