Description

A kind of multilayer electrical brush group
Technical field
The utility model is related to electrical-mechanical servo drive fields, are specifically related to a kind of multilayer electrical brush group.
Background technology
Brush group is the important component of electrical servo transmission, but existing brush group, contact portion are by shrapnel and bullet Spring axle sleeve is in direct contact, and structure design is unreasonable, excessively thin using copper sheet, causes easy to wear and service life short, and electric conductivity dissipates It is hot that there is also prodigious problems.
Utility model content
The utility model is in order to solve the above technical problems, provide a kind of suitable for rotary motion, simple in structure, user Just, stablize durable multilayer electrical brush group.
In order to solve the above technical problems, a kind of multilayer electrical brush group provided by the utility model, including complex root conducting wire, plural number A bakelite insulating trip, a plurality of spring axle sleeves, a plurality of brushes, a plurality of shrapnels, brushgear housing, brush carriage, the brushgear housing On the brush carriage, each shrapnel includes bending section and vertical component effect, and the vertical component effect is fixed on brushgear housing, Bending section is all connected to each brush, and each bakelite insulating trip is mutually superimposed, and each bakelite insulating trip is set to electricity On brush holder, each spring axle sleeve is both placed among two adjacent superposition bakelite insulating trips, each spring axle sleeve It is fitted closely with bakelite insulating trip, each spring axle sleeve is annular shape, and each conducting wire both passes through bakelite insulation Piece is connected to each spring axle sleeve, and each spring axle sleeve is all connected with a conducting wire.
Preferably, each bakelite insulating trip is equipped with plurality of through holes, there are one each spring sleeve lining is all provided with Wiring hole, each wiring hole site is corresponding with each through-hole on bakelite insulating trip, and each conducting wire both passes through bakelite Insulating trip connect each bakelite insulating trip and spring axle sleeve with the through-hole of spring axle sleeve and wiring hole.
Preferably, the bakelite insulating trip is equipped with 4, and the spring shaft is arranged with 3, and the brush is described equipped with 3 Shrapnel is equipped with 3.
Preferably, each shrapnel is located at same level with brush junction and the center of circle of spring axle sleeve.
By using above-mentioned technical solution, the utility model has the beneficial effects that:The utility model shrapnel includes curved Pars convoluta and vertical component effect, the vertical component effect are fixed on brushgear housing, and bending section is all connected to each brush, and this structure design enables electricity Brush have certain elasticity, can to avoid spring shaft cover surface it is excessively coarse, it is in irregular shape caused by frictional force increase and The frictional force that non-standard operation in installation process causes brush and spring axle sleeve tension to generate increases, and allows the use of the new type energy Higher rotating speed is born, working performance is more stablized, and the bakelite that each spring axle sleeve is both placed in two neighboring superposition is exhausted Among embolium, each spring axle sleeve is fitted closely with bakelite insulating trip, and each conducting wire both passes through bakelite insulating trip It is connected to each spring axle sleeve, each spring axle sleeve is all connected with a conducting wire, and this structure makes the width of spring axle sleeve Degree can maximize, it is not necessary to which considering whether can be short-circuit because of spring axle sleeve is excessive when leading to work contact, can also enable brush Increase with the contact area of spring axle sleeve, to improve the Greatest load by electric current, voltage, and conduction loss is subtracted It is few and easy to assembly, stable and reliable in work.
