Abstract

The invention discloses a novel plastic gear which comprises a gear body and a plurality of gear teeth arranged on the outer periphery of the gear body. The gear body and the gear teeth are integrated and are made of high-strength nylon plastics. Polytetrafluoroethylene coating layers are arranged on the outer surfaces of the gear teeth. A shaft hole is formed in the center portion of the gear body. The novel plastic gear is high in strength and light in weight, good self-lubricating performance is achieved, and meshing abrasion between the gear teeth can be lowered.

Description

technical field [0001] The invention relates to the technical field of gears, in particular to a novel plastic gear. Background technique [0002] The gear industry has developed rapidly in our country. Gears are toothed mechanical parts that can mesh with each other, and the application of gears in transmission has appeared very early. At present, most of the gears are made of metal, the production cost is high, and the weight is heavy; there are also some plastic gears, but the self-lubricating performance of the existing plastic gears is not good. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a new type of plastic gear with high strength, light weight, good self-lubricating performance, and can reduce meshing wear between teeth. [0004] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a new type of plastic gear, comprising: a gear body an...
