Abstract
The invention discloses a direct current control series excitation motor single-chip carbon brush which mainly comprises a copper tube; the front end of the copper tube is provided with a carbon brush; the carbon brush is characterized in that the carbon brush is single-chip and integrated. The direct current control series excitation motor single-chip carbon brush is of a single-chip structure; no bonding process is carried out during a production process; and in addition, due to the single-chip structure, the quality is convenient to control and the end surface levelness of two half chips does not need to be controlled. What is more, due to the single-chip structure, no binder needs to be adopted for bonding, so that a working face of the carbon brush is not affected by the binder when the carbon brush works. In such a manner, the vibration during work is reduced, the wear of a commutator is reduced, the vibration and noise are reduced during the whole service life, and the service life of the whole motor is prolonged.
Description
Technical field
The present invention relates to a kind of carbon brush, particularly a kind of DC control series excited machine monolithic carbon brush.
Background technology
The direct current machine electric current flows towards a direction, make the carbon brush abrasion of negative pole larger, and for commutator segment, positive pole weares and teares larger on the contrary.Further affect simultaneously the wearing and tearing of commutator due to the wearing and tearing meeting of carbon brush, finally cause the running noises of motor to increase, vibrations increase.The increase of vibrations, the wearing and tearing that can be further again aggravation enters vicious circle, makes the lost of life of motor.As shown in Figure 1, in prior art, the carbon brush 2 of DC control series excited machine is that 3, two half sheet carbon brush of two chip architectures are by complete carbon brush 2 of the bonding rear composition of glue.The carbon brush of this two-piece type structure at work, the wear extent of up and down two and half sheets differs, and can cause vibrations to increase, adhesive simultaneously also can participate in the friction of machine operation, making affects the working face that carbon brush contacts with rotor, increases vibrations, makes the wearing and tearing aggravation.
Summary of the invention
The objective of the invention is provides a kind of convenient for production, anti abrasive DC control series excited machine monolithic carbon brush for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the DC control series excited machine monolithic carbon brush that the present invention is designed, it mainly comprises copper pipe, at the front end of copper pipe, carbon brush is set, and it is characterized in that described carbon brush is that monolithic is integrated.
The resulting DC control series excited machine of the present invention monolithic carbon brush adopts single chip architecture, and in production process, without adhesion process, and owing to being single chip architecture, quality control is convenient, need not to control the end face evenness of two halves sheet.In addition, owing to being single chip architecture, need not adhesive bonding, when making carbon brush work, its working face can not be subjected to the impact of adhesive.Thereby the vibrations when having reduced work have reduced the wearing and tearing of commutator, are clicking whole length of life minimizing vibrations and noise, have extended the useful life of whole motor.
