Abstract

The utility model discloses a kind of carbon brush structure-improved, including carbon brush body, the carbon brush body, which is provided with, is used to abutting the abutment end of commutator, the inclined structure in axial direction of the end face of the abutment end along commutator.A kind of carbon brush structure-improved of the utility model, its is rational in infrastructure, can effectively shorten the running-in time of carbon brush and commutator, so as to improve noise problem of the motor in initial operating stage.

Description

A kind of carbon brush structure-improved

Technical field

It the utility model is related to a kind of carbon brush structure-improved.

Background technology

Carbon brush, brush is also, is a kind of sliding contact parts being widely used in motor or engine.Carbon brush is used for In motor or generator or other rotating machineries between fixed part and rotating part energy transmission, typically pass through spring Carbon brush is pressed on commutator face or current collection ring surface by pressure, so that carbon brush is stable between fixed part and rotating part Conduct electric current in ground.Under the action of the spring, carbon brush contacts with commutator face or current collection ring surface all the time, makes the circuit of motor all the time State in UNICOM.At present, contact of the carbon brush of the prior art with commutator is always that face contacts, at the beginning of motor operation The running-in time of phase, carbon brush and commutator is longer, and noise is larger.

Utility model content

The purpose of this utility model is to provide a kind of carbon brush structure-improved, and its is rational in infrastructure, can effectively shorten carbon brush with The running-in time of commutator, so as to improve noise problem of the motor in initial operating stage.

To achieve the above object, the technical solution of the utility model is to design a kind of carbon brush structure-improved, including carbon brush sheet Body, the carbon brush body, which is provided with, is used to abutting the abutment end of commutator, and the axial direction of the end face of the abutment end along commutator is in inclining Biassed fabric.By using such scheme, the contact of carbon brush and commutator at motor operation initial stage is set to be changed to linear contact lay by face contact, The effective running-in time for shortening carbon brush and commutator, so as to improve noise problem of the motor in initial operating stage.

Preferably, the carbon brush body is extended with carbon brush mounting head in one end opposite with above-mentioned abutment end.By using Such scheme, it is easy to carbon brush being fixedly mounted on carbon brush holder.

Brief description of the drawings

Fig. 1 is schematic diagram of the present utility model.

Embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below Example is only used for clearly illustrating the technical solution of the utility model, and can not limit protection model of the present utility model with this Enclose.

The utility model specific implementation technical scheme be：

As shown in figure 1, a kind of carbon brush structure-improved, including carbon brush body 1, the carbon brush body 1 are provided with and changed for abutting To the abutment end 2 of device, the inclined structure in axial direction of the end face of the abutment end 2 along commutator.By using such scheme, make carbon The contact of brush and commutator at motor operation initial stage is contacted by face is changed to linear contact lay, effectively shortens the mill of carbon brush and commutator The time is closed, so as to improve noise problem of the motor in initial operating stage.

In addition, for ease of carbon brush body 1 is fixedly mounted on carbon brush holder, above-mentioned carbon brush body 1 is opposite with abutment end 2 One end be extended with carbon brush mounting head 3.

Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of the utility model technical principle is not departed from, some improvements and modifications can also be made, these change Enter and retouch and also should be regarded as the scope of protection of the utility model.

Claims

1. a kind of carbon brush structure-improved, including carbon brush body, the carbon brush body is provided with the abutment end for being used for abutting commutator, its It is characterised by, the inclined structure in axial direction of the end face of the abutment end along commutator.

2. carbon brush structure-improved according to claim 1, it is characterised in that the carbon brush body with above-mentioned abutment end phase One end of the back of the body is extended with carbon brush mounting head.
