Abstract
The invention discloses a carbon brush of a motor of a drum washing machine. The carbon brush of the motor is characterized by comprising, by weight, from 80% to 90% of graphite powder, from 7% to 15% of asphalt and from 2% to 5% of tungsten powder. A method for manufacturing the carbon brush of the motor of the drum washing machine includes steps of adding the graphite powder, the asphalt and the tungsten powder into a mixer according to the respective weight percentages, and sufficiently mixing the graphite powder, the asphalt and the tungsten powder; feeding a mixture into a grinder after the graphite powder, the asphalt and the tungsten powder are sufficiently mixed to obtain the mixture, grinding the mixture, and sieving powder obtained after the mixture is ground; performing compression moulding for the powder; sintering; cutting and grinding surfaces after sintering is completed; coating solid glue on two surfaces of a crude product of the carbon brush of the motor after the surface grinding is completed to obtain the crude product; and then punching, embedding wires and grinding arcs to obtain a finished product. The grain size of screen cloth is 100 meshes. The carbon brush and the method have the advantages that a process is simple, conditions are easy to realize, the carbon brush obtained by the method is low in breakage rate and long in service life, loss can be effectively reduced, and the production cost can be effectively saved.
