Abstract
The invention discloses a carbon brush used for a multi-hole electric hammer. The carbon brush comprises a carbon brush head and a carbon brush base, wherein the carbon brush head is connected with the carbon brush base through a wire. A penetrating hole is formed in the carbon brush base, the penetrating hole penetrates through the carbon brush base, a cylindrical boss is arranged on the carbon brush base, the wire is sleeved with a spring, one end of the spring is fixed to the bottom of the carbon brush head, and the other end of the spring wraps the cylindrical boss. The spring can compensate the abrasion to the contacting surface of the carbon brush and transmit part of heat so that heat of the carbon brush base can be timely dissipated. Due to the fact that the penetrating hole is formed in the carbon brush base, in the operation process of the carbon brush, the temperature can be effectively lowered, noise can be obviously lowered, and the service life can be 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.In addition, the carbon brush of electric angle grinder in use, has the relation of mutual restriction and contradiction between the technical indicator of noise, temperature rise, useful life and electrical property, is difficult to take into account comprehensively and ensure the performance such as life-span, noise, temperature rise of brush.
Summary of the invention
The technical problem to be solved in the present invention is to provide the carbon brush that the porous electric hammer of the performances such as a kind of life-span that can take into account and ensure brush, noise, temperature rise is used.
For addressing the above problem, the technical scheme that the present invention takes is: a kind of porous electric hammer carbon brush, comprise carbon brush head and carbon brush holder, the carbon brush head is connected with carbon brush holder by wire, is provided with perforation on carbon brush holder, and perforation runs through carbon brush holder, 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 further improved technical scheme of the present invention, the shape of cross section of described perforation is circle, ellipse, triangle, quadrangle.
As a modification of the present invention, wire is copper core flexible cord, and the carbon brush head is the copper sheet metal.
The perforation that the present invention arranges on carbon brush holder, make carbon brush be in operation effective temperature-reducing, obviously improve noise, life-saving, in addition, spring is as an elastic force apparatus, and 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, 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 principal section figure of the present invention.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention will be further described.
This porous 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 3, be provided with perforation 5 on carbon brush holder 1, bore a hole and 5 run through carbon brush holder 2, carbon brush holder 2 is provided with cylindrical boss wire 3 overcoats spring 6, one end of spring 6 is fixed on carbon brush head 1 bottom, the other end parcel cylindrical boss 4 of spring 6, wire 3 is copper core flexible cord, carbon brush head 1 is the copper sheet metal.Spring in this porous electric hammer use carbon brush 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, 4, 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, the perforation arranged on carbon brush holder, make carbon brush be in operation effective temperature-reducing, obviously improve noise, life-saving.
