Description
Technical field
A kind of carbon brush component is the utility model is related to, more particularly, to a kind of carbon brush component with arc spring groove.
Background technology
Carbon brush is also brush, as a kind of slide contact member, is widely used in many electrical equipments.Carbon brush exists
Products application material mainly has graphite, soaks fat graphite, metal（Cupric, silver）Graphite.Carbon brush be motor or generator or other
The device of energy or signal is transmitted between the fixed part and rotating part of rotating machinery, it is usually that pure carbon adds coagulator system
Into external form is usually square, is stuck on metallic support, and there is spring handle in the inside, and it is pressed in shaft, will when motor rotates
Electric energy is conveyed to coil by phase changer, since its main component is carbon, is known as carbon brush, it is easy to wear, answers periodic maintenance
Replace, and clear up carbon distribution.
The carbon brush in motor often adds one to firmly be pressed in carbon brush in shaft on the end face of carbon brush at present
A constant force spring.But since the end face of current carbon brush is all smooth end face, and the curling face of constant force spring is arc-shaped,
When carbon brush is during moving up and down, the position of constant force spring often shifts so that pressure of the constant force spring to carbon brush
Power changes, so as to have impact on the electric current that carbon brush is transmitted, ultimately results in the unstable of motor operation.
Such as a kind of a kind of brush holder for electric motor disclosed in Chinese patent literature, its Authorization Notice No. is CN
205178241 U, it includes insulation shell, conduct piece, carbon brush component, and the conduct piece includes a part and is arranged in insulation shell
Tube body and a carbon brush sliding slot on the inside of tube body, the side wall front end of the conduct piece have a perforation, the carbon brush component bag
A carbon brush and a constant force spring are included, the carbon brush is slideably arranged in the carbon brush sliding slot of conduct piece, the rear end of the carbon brush
Face is arranged in carbon brush sliding slot and is electrically connected at conduct piece, and one end of the constant force spring pushes the rear end face in carbon brush, separately
One end is worn in the perforation for being fastened in conduct piece.Although the more traditional brush holder for electric motor of the utility model provides more stable brush
Press, but be the contact between plane and arc surface between its carbon brush and constant force spring, the constant force spring of arc-shaped is easily in plane
Carbon brush on slide, cause motor operating have some setbacks.
Utility model content
The utility model is easily subjected to displacement between carbon brush end face and constant force spring in the prior art to overcome, carbon brush by
The problem of power is uneven, and motor operating has some setbacks, there is provided will not be subjected to displacement between a kind of carbon brush and constant force spring, carbon brush stress
Uniformly, a kind of motor operation smoothly carbon brush component with arc spring groove is ensured.
To achieve these goals, the utility model uses following technical scheme：
A kind of carbon brush component with arc spring groove, including brush-box, carbon brush and constant force spring, the brush-box is in length
Cube, is internally provided with the carbon brush sliding slot of a perforation brush-box, the side of the brush-box is perforated equipped with a spring, described
The front of brush-box is additionally provided with rectangle fluting；The carbon brush is slidably connected to inside carbon brush sliding slot, the upper end Middle face
Spring groove equipped with an arc, the size of the spring groove and the curling face of constant force spring match, the carbon brush lower end
Face is equipped with the curved end that shape is adapted with commutator shape, and the carbon brush front is additionally provided with the extraction of a conduction electric current
Line；The constant force spring end is additionally provided with the buckle end being mutually buckled that can perforate with spring.
Cooperate between brush-box, carbon brush and constant force spring, enable to carbon brush to ensure at work to turning
Axis has a constant pressure, so that remaining constant by the size of current of carbon brush transmission, ensure that the normal of motor
Operating.Carbon brush upper surface is provided with the spring groove of an arc, spring grass is adapted with the curling face of constant force spring so that permanent
The curling face of power spring can be placed in spring groove just, so that constant force spring and carbon brush during the moving up and down of carbon brush
Between relative displacement will not occur so that constant force spring is equal to the active force moment of carbon brush.Then, export or lead from lead-out wire
The electric current entered remains unchanged, and further ensure that the normal operation of motor.
Preferably, the carbon brush front is additionally provided with limited post, the limited post is internal positioned at fluting.Set spacing
Column enables to carbon brush not depart from brush-box because of moving up and down.
Preferably, the top for being connected to limited post of the lead-out wire.By the top for being connected to limited post of lead-out wire
End enables to lead-out wire mutually not wound with the other parts in motor because of moving up and down for carbon brush.
Preferably, the lead-out wire is located in the lower edge side of the close spring groove of carbon brush.Lead-out wire is located at
The lower edge side of the close spring groove of carbon brush, the reduction for enabling to the length of lead-out wire to try one's best, so that will not be with other
Component mutually wind.
Preferably, the height of the limited post is less than carbon brush front to the positive distance of brush-box so that carbon brush exists
It can be just stuck in during moving up and down in brush-box, and keep brush-box front smooth.
Therefore, the utility model has the advantages that：（1）Relative displacement will not occur between carbon brush and constant force power supply；
（2）The pressure size that carbon brush is subject to is constant；（3）It can ensure that motor runs well.
