▎ 摘 要
NOVELTY - Gear system is made of graphene-lubricated plastic, and includes central wheel, multiple of planet wheels of the same size and meshed with the central wheel, and ring gear meshed with the planet wheel. The central wheel, planetary gear and ring gear are integrally formed bodies made of graphene nanosheet self-lubricating plastic. USE - Gear system for two-wheel electric vehicle. ADVANTAGE - The gear system is self-lubricating, non-deformative and silent, has high strength, strong wear resistance, high temperature resistance, light weight, low cost, wide range of application and strong practicability because it contains graphene nanosheet self-lubricating plastic that uses edge graphene nanosheets and engineering plastics as the main raw materials.
