Problems solved by technology

[0002] At present, the carbon brushes used in wind power generators use copper powder and graphite powder as raw materials and are processed and formed by roasting. Since the ash-containing gas generated by the roasting furnace during the roasting process is directly discharged into the atmosphere, it not only pollutes the surrounding environment, but also easily damages the product. Oxidation occurs on the surface layer, and the oxide layer needs to be ground off after roasting, which increases the process and labor intensity. Generators are expensive to run

Abstract

The invention discloses a carbon brush for a wind power generator, which is made of the following components in mass percentage: 50-60% of graphite powder, 38-42% of electrolytic copper powder, 1-3% of zinc powder and 1-5% of aluminum powder %. The carbon brush of the present invention uses a reasonable ratio of powder raw materials and adopts a closed roasting process, so that the surface layer of the carbon brush product will not be oxidized, has high strength and quality, can effectively alleviate the heating phenomenon of the carbon brush during use, and avoid The generation of running sparks prolongs the service life of the wind power generator by 10-20%, and also reduces the production cost, simplifies the process, has no pollution to the environment, and is more green and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of carbon brush manufacture, and in particular relates to a carbon brush for a wind power generator and a manufacturing method thereof. Background technique [0002] At present, the carbon brushes used in wind power generators use copper powder and graphite powder as raw materials and are processed and formed by roasting. Since the ash-containing gas generated by the roasting furnace during the roasting process is directly discharged into the atmosphere, it not only pollutes the surrounding environment, but also easily damages the product. Oxidation occurs on the surface layer, and the oxide layer needs to be ground off after roasting, which increases the process and labor intensity. Generators are expensive to operate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a carbon brush for a wind-driven generator and a manufacturing method thereof, ...
