Abstract
The utility model relates to an electrical brush processed and made by carbon or carbon composite material, which is characterized in that: the electrical brush [1] is processed and made by carbon or carbon composite material. The electrical brush obviously improves the comprehensive physical and mechanical performances of the electrical brush; the resistivity and the abrasion resistance performance of the product can be controlled by adjusting the structure and density of the composite material; the abrasion of the electrical brush is lower than 0.18mm/50h, and the abrasion of the current electrical brush is generally higher than 0.20mm/50h.
Description
Technical field:
The utility model relates to a kind of motor part, specifically a kind of engine commutator brush.
Background technology:
Brush is the sliding contact part on the engine commutator, and one is transmission current in motor rotation; The 2nd, commutation.Because the rotation of rotor, brush rubs with commutative ring all the time, and produces the bright erosion of electric spark in the moment of commutation toward the contact meeting.Because the requirement of the job specification of brush, brush not only will have excellent conducting performance, but also good commutation ability, greasy property, stability and performance such as heat-resisting, are-tight, wear-resisting will be arranged.With the brush of Cu or Ag preparation, have good electrical conductivity, but resistance to wear is very undesirable.Brush with alloy such as Cu-Ni or the preparation of Cu-graphite composite material preferably resolves resistance to wear, but has damaged conductivity.The carbon fiber reinforced carbon based composites that carbon/carbon composite is made up of the pure carbon element, its moulding is combined into prefabricated component by charcoal fleece and charcoal cloth through lamination acupuncture and (or directly makes prefabricated component by charcoal cloth lamination, or directly make prefabricated component by the mat lamination, or substitute the charcoal fiber with pre-oxygen silk and make prefabricated component) by said method, by chemical vapour deposition (CVD) and/or dipping density (pitch or resin), make through follow-up charing (as needs) and/or graphitization and/or machining processes again.Have good resistance to wear and proper conductivity, also have characteristics such as high specific strength, high ratio modulus, high temperature resistant, anti-ablation, existing big current capacity has good commutation ability and sliding contact performance again, can satisfy the instructions for use of brush preferably, be a kind of novel brush material.
Summary of the invention:
The purpose of this utility model provides a kind of brush that adopts carbon/carbon composite to be processed into.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of brush, and described brush is processed into by carbon/carbon composite.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, the comprehensive physics and the mechanical property of brush have obviously been improved, by adjusting the structure and the density of composite material, the resistivity of may command product and anti-wear performance, the wear extent of brush is lower than 0.18mm/50h, and present employed brush, its wear extent generally is higher than 0.20mm/50h.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
By accompanying drawing as can be known, a kind of brush, described brush 1 are processed into by carbon/carbon composite.
Carbon/carbon composite is processed into the brush 1 of required form, assembling finished products such as brush 1 and brush wire and sleeve pipe 3, joint 4, cushion block 2 can be come into operation.
The carbon fiber reinforced carbon based composites that carbon/carbon composite described in the utility model is made up of the pure carbon element, its moulding is combined into prefabricated component by charcoal fleece and cloth through lamination acupuncture, again by making after chemical vapour deposition (CVD) density, the machine work.
