Abstract
The invention discloses a carbon brush for an electric hammer. The carbon brush for the electric hammer comprises a carbon brush head and a carbon brush base, the carbon brush head is connected with the carbon brush base through a wire, a cylindrical boss is arranged on the carbon brush base, the wire is sleeved with a spring, one end of the spring is fastened to the bottom of the carbon brush head, and the other end of the spring wraps the cylindrical boss. The spring can compensate abrasion of the contact surface of the carbon brush, transmits a part of heat to enable the heat of the carbon brush base to be radiated timely, and therefore the service life of the carbon brush for the electric hammer is prolonged.
Description
?
Technical field
The present invention relates to a kind of carbon brush, in particular for the carbon brush of electric hammer.
Background technology
The electric hammer carbon brush is the device of transferring energy or signal between the standing part of motor or generator or other rotating machineries and rotating part, it is generally that pure carbon adds coagulating agent and makes, external form is generally square, is stuck on metallic support, on top, has wire to draw, in running up, the carbon brush conduction current, due to and carbon brush holder and electric hammer between CONTACT WITH FRICTION, make surface occur wear away and to produce hot, heat can't shed in time, and shorten useful life.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of electric hammer carbon brush that can increase the service life.
For addressing the above problem, the technical scheme that the present invention takes is: a kind of electric hammer carbon brush, comprise carbon brush head and carbon brush holder, the carbon brush head is connected with carbon brush holder by wire, carbon brush holder is provided with cylindrical boss, the wire overcoat has spring, and an end of spring is fixed on carbon brush head bottom, the other end parcel cylindrical boss of spring.
As a modification of the present invention, wire is copper core flexible cord, and the carbon brush head is the copper sheet metal.
Adopt said structure, spring is as an elastic force apparatus, the spring handle carbon brush is pressed in rotating shaft, promoting the close contact that carbon brush moved and kept this carbon brush and this rotor, prevent the change of carbon brush position, linking springs can compensate the abrasion of the contact surface of carbon brush in addition, transmits a part of heat, the heat of carbon brush holder is distributed in time, increase the service life.

The accompanying drawing explanation
Accompanying drawing is structure chart of the present invention.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention will be further described.
This electric hammer carbon brush, comprise carbon brush head 1 and carbon brush holder 2, carbon brush head 1 is connected with carbon brush holder 2 by wire 4, carbon brush holder 2 is provided with cylindrical boss 5, wire 2 overcoats have spring 4, and an end of spring 4 is fixed on carbon brush head 1 bottom, the other end parcel cylindrical boss 5 of spring 4, wire 2 is copper core flexible cord, and carbon brush head 1 is the copper sheet metal.Spring is as an elastic force apparatus, the spring handle carbon brush is pressed in rotating shaft, promoting the close contact that carbon brush moved and kept this carbon brush and this rotor, prevent the change of carbon brush position, this outer spring can compensate the abrasion of the contact surface of carbon brush, transmit a part of heat, the heat of carbon brush holder is distributed in time, increase the service life.
