Abstract

The invention discloses a method for manufacturing a bicycle sprocket set, which comprises the following steps: connecting a first sprocket and a second sprocket of different sizes in advance by means of a plurality of pins; The first and second inner ring parts respectively have a plurality of first male connectors and second male connectors, and the first male connectors and the second male connectors are respectively provided with a first positioning hole and a second positioning hole, Move the above-mentioned combination of the first sprocket and the second sprocket connected together by the pin into a molding mold, and pour and mold a sprocket seat according to the shape of the mold. The center of the sprocket seat has a A set of matching holes, the outer ring of the sprocket seat is arranged with a plurality of connecting arms, the connecting arms cover the first male connector and the second male connector to form a sprocket product, thereby achieving modularization and eliminating the trouble of riveting , to enable rapid manufacturing and lightweight products.

Description

technical field [0001] The invention relates to a bicycle sprocket, in particular to a method for manufacturing a bicycle sprocket set which can be manufactured quickly through modularization and can reduce manufacturing costs. Background technique [0002] The sprocket set of a general variable speed bicycle has a plurality of sprockets of different sizes and numbers of teeth, which are assembled together on a sleeve, and the sleeve is also sleeved on the mandrel of a rear hub, which is connected to the rear wheel of the bicycle. connected, and stepping on the bicycle pedal will drive a large chainring group to rotate, and the large chainring group and the sprocket group are connected together by a chain, which can be used to adapt to different road conditions by using a transmission of the bicycle to change the chain to hang the large tooth One of the large chainrings of the disc set and one of the sprockets of the sprocket set drive the bicycle forward. [0003] As the n...
