Abstract
The invention discloses a carbon fiber electric brush housing with a guiding structure, comprising an electric brush fixing base for fixing the carbon fiber electric brush; the electric brush fixing base is provided with a housing; the brush furs of the carbon fiber electric brush are projected out of the opening of the housing; the front end of the housing is provided with a guiding side; and the guiding side is bent along the bending direction of the brush furs. The housing is provided with a guiding side bending along the bending direction of the brush furs, and the guiding side has functions of guiding and limiting for the furs of the carbon fiber electric brush. When a commutator rotate with a high speed, the guiding side enable the brush furs to be in good contact with the commutator and guarantees the circuit to be not faulted.
Description
Technical field
The present invention relates to motor accessory field, be specifically related to a kind of carboloy bilber brush case with guiding structural.
Background technology
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, and electrographite brush main body is the graphite block of rigidity, adopts spring to push and makes electrographite brush and commutator keep good contact.But electrographite brush and epitrochanterian commutator are when relative running, and electrographite brush 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; In addition, rigidity friction between electrographite brush and commutator can as sand paper at abrading object, cause the wearing and tearing of electrographite brush, namely the wear of brush electrical machinery life that is over terminates, existing electrographite brush 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.
Adopt soft conduction hairbrush can realize the soft contact with engine commutator, solve the problem that existing wear of brush is serious, but soft hairbrush is when commutator rotates, easily occurs the situation of loose contact, cause circuit breaker, therefore need to guide soft bristle.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of carboloy bilber brush case with guiding structural, well can guide the bristle of carboloy bilber brush, make the commutator of itself and motor keep good contact.
The technical solution adopted for the present invention to solve the technical problems is:
With the carboloy bilber brush case of guiding structural, comprise the brush carrier block for fixed carbon fiber brush, described brush carrier block is provided with case, the bristle of described carboloy bilber brush stretches out from the opening of case front end, described case front end is provided with leading edge, and described leading edge bends along bristles bend direction.
As the further improvement of technique scheme, described brush carrier block is connected by buckle with case, and brush carrier block both sides are provided with fixture block, described case is provided with the through hole of the fixture block coordinating brush carrier block.
The invention has the beneficial effects as follows:
Case of the present invention is provided with the leading edge along the bending of bristles bend direction, the bristle of leading edge to carboloy bilber brush has guiding and spacing effect, and when commutator high-speed rotates, leading edge can make the contact of bristle and commutator good, ensures circuit not open circuit.
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.
Embodiment
With reference to Fig. 1, the invention provides a kind of carboloy bilber brush case with guiding structural, carboloy bilber brush 1 is provided with for fixing brush carrier block 2, described brush carrier block 2 is provided with case 3, the bristle of carboloy bilber brush 1 stretches out from the opening of case 3 front end, described case 3 front end is provided with leading edge 31, and described leading edge 31 bends along bristles bend direction.Case 3 of the present invention is provided with the leading edge 31 along the bending of bristles bend direction, the bristle of leading edge 31 pairs of carboloy bilber brush 1 has guiding and spacing effect, when commutator high-speed rotates, leading edge 31 can make the contact of bristle and commutator good, ensures circuit not open circuit.
Further, described brush carrier block 2 is connected by buckle with case 3, and brush carrier block 2 both sides are provided with fixture block, described case 3 is provided with the through hole of the fixture block coordinating brush carrier block 2.
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.
Claims (2)
1. be with the carboloy bilber brush case of guiding structural, it is characterized in that: comprise the brush carrier block for fixed carbon fiber brush, described brush carrier block is provided with case, the bristle of described carboloy bilber brush stretches out from the opening of case front end, described case front end is provided with leading edge, and described leading edge bends along bristles bend direction.
2. the carboloy bilber brush case of band guiding structural according to claim 1, it is characterized in that: described brush carrier block is connected by buckle with case, brush carrier block both sides are provided with fixture block, described case are provided with the through hole of the fixture block coordinating brush carrier block.
