Abstract
The invention relates to a one-shot compression molding dual-layer composite electric brush with a wire, which comprises an electric brush body and a wire, wherein the electric brush body is composed of an electric brush layer and an electric brush sliding-out side layer. The dual-layer composite electric brush is characterized by utilizing various properties of brush materials, and changing the conventional electric brush of one layer structure made of identical material into two layers, namely the electric brush layer and the electric brush sliding-out side layer, wherein the electric brush sliding-out side layer is a high resistance electric brush sliding-out side layer made of high resistance materials and has functions of improving commutation performance, inhabiting spark and electromagnetic interference resistance, and the inner layer, namely the electric brush layer is a basic conductive layer, which maintains electrical property of the conventional electric brush, thereby increasing abrasion resistance and service life of the electric brush. The dual-layer composite electric brush overcomes contradiction among electrical property, abrasion resistance and performances of commutation, spark inhabitation and electromagnetic interference resistance.
Description
Technical field
The present invention relates to a kind of band lead one-time molded double layer composite electric brush.
Background technology
At present brush in use, brush and engine commutator formation sliding contact can produce mechanical friction loss and galvanic corrosion loss.The galvanic corrosion loss is by brush and commutator produces the electric spark ablation brush because of exchanging electrical current and commutator produces, and this electricity ablation is the main cause of brush loss.
Summary of the invention
Technical problem to be solved by this invention provides a kind ofly can effectively improve commutation ability of brush, suppress spark, anti-electromagnetic interference performance, and thereby the electrical property that can effectively keep traditional brush improves the brush resistance to wear, improves the brush band lead one-time molded double layer composite electric brush in useful life.
The used following technical scheme of the present invention:
The present invention includes brush body and lead, it is characterized in that the brush body skids off boundary layer by brush layer and brush and constitutes.
It is that the high resistance brush that a kind of high-resistance material is made skids off boundary layer that brush of the present invention skids off boundary layer.
Good effect of the present invention is: the present invention utilizes the different performance of brush material, change traditional identical material-structure of brush one deck into two layers, be that brush layer and brush skid off boundary layer, it is that the high resistance brush that a kind of high-resistance material is made skids off boundary layer that brush skids off boundary layer, acting as of it improves commutation ability, suppresses spark, anti-electromagnetic interference, internal layer is that the brush layer is basic conductive layer, thereby keeps the electrical property of traditional brush to improve the brush resistance to wear, improves brush useful life.The present invention has overcome traditional brush electrical property and resistance to wear and commutation ability, has suppressed the contradiction of the performance of spark, electromagnetic interference.
It is 12V centering type retard start motor (QDJ1404) that the starter model is adopted in properties of brush test of the present invention.
Experimental condition:
1.HS20-1 type silicon rectifier DC power supply;
2.SF138 single-cylinder engine;
3.12V centering type retard start motor QDJ1404;
4. started 3 seconds, counter dragging 1 second had a rest 40 seconds;
5. actuating motor air blast cooling.
Result of the test:
(1) properties of brush: the vertical electrical property of installation this composite brush of Pretesting: 0.16-0.24 μ Ω m
Transverse electric performance: (bilayer) 2.8-3.6 μ Ω m.
(2) dynamic property: motor is shut down after normally moving 30000 times on the engine, and the machine of tearing open is measured brush and commutator, and the brush original height is 17.10mm, and after 30000 tests, brush remains the work height:
Just brush: the negative brush of 13.88mm 13.65mm: 13.18mm 12.96mm
Wear of brush amount: 3.22mm 3.45mm 3.92mm 4.14mm
Commutator face is dark-brown, and oxide-film is even, no scaling loss vestige, no marking.Commutation skids off the limit light blue point-like sparklet, grade of spark
Level.
Diameter phi 33.10mm before the commutator test, test back diameter is φ 32.82mm, commutator wear 0.28mm.
Conclusion:
Band lead one-time molded double layer composite electric brush M501/7*19*17 of the present invention is contained in and makes life test on the single-cylinder engine, after starting 30000 times, motor still can normally move, commutator wear 0.28mm, wear of brush 3.22-4.14mm presses brush height in hand 7mm and calculates, brush life can reach 5.07 ten thousand times and (press QC/T731-2005 normal benzine engine with starter life-span 3.5 ten thousand times, the used for diesel engine starter life-span 20,000 times), commutation spark is very little during starting, grade of spark
Level.
