Abstract

The invention provides a transmission gear for an electric motor bicycle, belonging to a part for transmission on the electric motor bicycle. The transmission gear for the electric motor bicycle comprises a base body, wherein the base body is made of steel; an installation hole is formed in the base body; one circle of first annular groove is formed in the interconnection between the external periphery wall of the base body and one side wall; a first annular insert made of nylon is poured in the first annular groove; multiple first through holes communicated with the first annular groove are uniformly distributed on another side wall of the base body; tapered hole sections are arranged on the first through holes; first inserts made of the nylon are poured in the first through holes and the tapered hole sections; the first inserts and the first annular insert are of an integral structure; multiple first gear teeth are processed on the excircle face of the base body; multiple second gear teeth are simultaneously processed on the excircle face of the first annular insert; the multiple first gear teeth and the multiple second gear teeth make up complete gear teeth in a one-to-one correspondence way. The transmission gear for the electric motor bicycle provided by the invention has the advantages of higher strength and lower noise at work.

Description

[0001] Technical field: [0002] The invention relates to a component used for transmission on an electric vehicle, in particular to a transmission gear for an electric vehicle. [0003] Background technique: [0004] At present, there are mainly two types of gears used in the deceleration mechanism of electric vehicles, one is steel gears, and the other is nylon gears. Steel gears have higher strength but have the disadvantage of loud noise during operation. , The gear made of nylon has the disadvantage of low noise but low strength during work. [0005] Invention content: [0006] The technical problem to be solved by the present invention is to provide a transmission gear for electric vehicles that not only has high strength but also has the advantages of low noise during operation. [0007] The technical solution of the present invention is to provide a transmission gear for electric vehicles with the following structure: it includes a base made of steel, and the base is ...
