Abstract
The present invention discloses a carbon fiber brush. The carbon fiber brush comprises a brush fixed base; and the brush fixed base is provided with brush of kernel made of conductive carbon fibers, one end of the brush of kernel extends out of the brush fixed base, and the other end of the brush of kernel is connected with wires. According to the invention, brush of kernel made of conductive carbon fibers is capable of heat resistance, soft and wear resistant, and is in soft contact with a commutator. When the carbon fiber brush and the commutator of a rotor are relatively running, the soft brush of kernel is close to the commutator and bends along the rotation direction of the commutator. The brush of kernel is not able to bounce and is not reliable to generation of spark, the friction generated between the brush of kernel and the commutator is very small without any noise, therefore the friction loss of the brush of kernel is greatly reduced, the carbon fiber brush is not reliable to wearing, and the service life of a motor is prolonged.
Description
Technical field
The present invention relates to motor accessory field, be specifically related to a kind of carboloy bilber brush.
Background technology
As shown in Figure 3, brush motor comprises stator, rotor, and rotor is provided with commutator, motor is provided with brush and contacts with commutator, guide electric current.Because rotor turns followed by commutator in machine operation process, rub mutually between brush and commutator, therefore, when making brush, the material with satisfactory electrical conductivity and resistance to wear must be chosen.Existing brush motor mainly adopts comparatively wear-resisting electrographite brush 1 ', and electrographite brush 1 ' main body is the graphite block of rigidity, adopts spring to push and makes electrographite brush 1 ' and commutator keep good contact.But electrographite brush 1 ' and epitrochanterian commutator are when relative running, and electrographite brush 1 ' is close on commutator and rubs, and is the friction of rigidity between the two, the noise of generation is very large, and beating and producing spark easily appears in electrographite brush 1 '; In addition, rigidity friction between electrographite brush 1 ' and commutator can as sand paper at abrading object, cause the wearing and tearing of electrographite brush 1 ', namely the wear of brush 1 ' electrical machinery life that is over terminates, existing electrographite brush 1 ' generally uses some months will all wear and tear by about 1 year, cause motor to scrap, have a strong impact on the useful life of motor.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of carboloy bilber brush, the soft contact with engine commutator can be realized, effectively reduce noise during electric machine rotation, reduce the attrition of brush, extend electrical machinery life.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of carboloy bilber brush, comprises brush carrier block, and described brush carrier block is provided with the bristle that conductive carbon fibre makes, brush carrier block is stretched out in bristle one end, and the other end is connected with wire.
As the further improvement of technique scheme, described brush carrier block is outside equipped with case.
As the further improvement of technique scheme, described case is provided with position-limited edge, described position-limited edge bends along bristles bend direction.
The invention has the beneficial effects as follows:
Carboloy bilber brush of the present invention adopts conductive carbon fibre to make bristle, the bristle that carbon fiber makes is high temperature resistant, and soft abrasion-resistant, and be soft contact between commutator, when the commutator of carboloy bilber brush and rotor is relative running, soft bristle is close to commutator and is bent along the direction that commutator rotates, bristle can not be beated, not easily produce spark, the friction produced between bristle and commutator is very little, does not almost have noise, greatly reduces the frictional dissipation of bristle, make carboloy bilber brush not easy to wear, extend the useful life of motor.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of carboloy bilber brush of the present invention;
Fig. 2 is the structural representation of the motor being provided with carboloy bilber brush;
Fig. 3 is the structural representation of existing electrographite brush motor.
Drawing reference numeral illustrates: 1, bristle; 2, brush carrier block; 3, case; 31, position-limited edge; 4, wire; 100, carboloy bilber brush; 101, rotor; 102, commutator; 103, motor housing; 1 ', electrographite brush.
Embodiment
With reference to Fig. 1, the invention provides a kind of carboloy bilber brush, comprise brush carrier block 2, brush carrier block 2 is provided with the bristle 1 that conductive carbon fibre makes, brush carrier block 2 is outside equipped with case 3, described case 3 is provided with the position-limited edge 31 of arc, brush carrier block 2 is stretched out from the outlet at position-limited edge 31 place in described bristle 1 one end, and the other end is connected with wire 4.
With reference to Fig. 2, be applied in the schematic diagram on motor for carboloy bilber brush of the present invention, described motor comprises rotor 101, stator (not shown) and motor housing 103, rotor 101 is provided with commutator 102.Carboloy bilber brush 100 is fixed on motor housing 103 by brush carrier block 2, and the bristle 1 of carboloy bilber brush 100 is close to commutator 102, and position-limited edge 31 is positioned at outside bristle 1, makes bristle 1 also can good contact with the commutator 102 of rotary state.Carboloy bilber brush 100 of the present invention adopts conductive carbon fibre to make bristle 1, the bristle 1 that carbon fiber makes is high temperature resistant, and soft abrasion-resistant, and be soft contact between commutator 102, when the commutator 102 of carboloy bilber brush 100 and rotor 101 is relative running, soft bristle 1 is close to commutator 102 and is bent along the direction that commutator 102 rotates, bristle 1 can not be beated, not easily produce spark, the friction produced between bristle 1 and commutator 102 is very little, almost there is no noise, greatly reduce the frictional dissipation of bristle 1, make carboloy bilber brush 100 not easy to wear, extend the useful life of motor.
The foregoing is only preferred embodiments of the present invention, as long as the technical scheme realizing the object of the invention with basic same approach all belongs within protection scope of the present invention.
