Abstract

The invention provides a standard harmonic assembly speed-reducing mechanism of an electric bicycle, which totally uses a marketized general standard harmonic transmission assembly, adds accessories, i.e. an inner sleeve and an outer sleeve of a flexible gear, on the flexible gear of the standard harmonic transmission assembly and increases the functions of the standard harmonic transmission assembly to meet the special requirements of the electric bicycle so that a standard part commodity of a core part, i.e. the harmonic transmission assembly, of a harmonic speed-reducing driving machine of the electric bicycle can be purchased in the market. The invention greatly reduces the manufacturing cost, provides the production efficiency and fast realizes the industrialization of a harmonic speed-reducing electric bicycle technology.

Description

[0001] The invention relates to a deceleration mechanism of a standard harmonic component of an electric bicycle. Background technique [0002] At present, the harmonic transmission components in the harmonic reduction mechanism of electric bicycles are all non-standard parts designed according to the special requirements used in electric bicycles. The shapes are complex and the manufacturing process requirements are high, so the production efficiency is very low and the cost is high. It is difficult to realize Mass production. Contents of the invention [0003] The purpose of the present invention is to provide a deceleration mechanism of a standard harmonic component of an electric bicycle, all of which use common standard harmonic transmission components that have been marketed. [0004] The solution adopted in the present invention is: adding accessories such as an inner flexible spline and a flexible spline outer sleeve to the standard harmonic transmission component fl...
