▎ 摘　　要

NOVELTY - The system has a metal body constituting a worm wheel and a worm, and a protective layer covering the metal body. A buffer layer is provided between the protective layer and the metal body. The raw materials of the protective layer include 10-20 parts by mass of diamond powder, 50-60 parts of molybdenum disulfide and 10-15 parts of binder.The raw materials of the buffer layer include 15-25 parts by mass of graphene, 25-30 parts of aluminum-doped zinc oxide powder, and 15-20 parts of phenolic resin conductive adhesive powder. The raw materials of the binder include 30-50 parts by mass of cyanoacrylate-polyethylene glycol copolymer powder and 15-20 parts of polyaniline. USE - Worm gear used in main reduction system of heavy-duty vehicles. ADVANTAGE - The protective layer is stabilized on the surface of the metal body to form a stable structure, so as to achieve the purpose of wear resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing a worm gear for a heavy-duty vehicle main reduction system.
