Modular multifunctional chain wheel

Abstract

The invention discloses a modular multifunctional chain wheel. The modular multifunctional chain wheel comprises a chain wheel body, wherein chain teeth are distributed on the chain wheel body; the chain teeth are formed on a plurality of chain tooth subsections in a continuous arrangement mode; a chain-tooth-free gap is formed between each two adjacent chain teeth of opposite sides of each two adjacent chain tooth subsections to form an intermittent chain wheel structure; the outer diameter of the portion, which is positioned on each gap, of the chain wheel body is equal to the diameter of aroot circle of each chain tooth; the chain tooth subsections are formed on an alloy insert; and the alloy insert is embedded on the chain wheel body, and is fixedly connected with the chain wheel bodythrough a screw. Preferably, the alloy insert is abutted against a plunger stage, the plunger stage is integrally formed on the chain wheel body, protruded sections which are protruded out of the chain wheel body are formed in the region, which corresponds to the plunger stage, of the back surface of the chain wheel body, and a gap with a set distance is formed between each two adjacent protrudedsections. The modular multifunctional chain wheel has the beneficial effects that pollution discharge and self-cleaning effects are good, the modular multifunctional chain wheel is speedy and convenient to change, resources are saved, the machining efficiency is high, and the manufacturing cost is low; and the modular multifunctional chain wheel is particularly suitable for driven chain wheels ofmotorcycles or bicycles.

Description

technical field [0001] The invention relates to a sprocket, in particular to a modular multifunctional sprocket. Background technique [0002] Most bicycles and motorcycles use chain transmission to transmit power. The sprocket includes a driving sprocket and a driven sprocket, which are also called small sprockets and Dalian wheels in the industry. The driving sprocket is connected with the output shaft of the engine, and the driven sprocket is connected with the driving wheel of the motorcycle through the buffer body. The chain drives of bicycles and motorcycles are open drives, which are used in harsh environmental conditions and poor lubrication conditions. Since all the sprocket teeth of the existing sprocket are evenly distributed on the sprocket, there is no mud discharge gap between adjacent teeth, and the sediment adhering to the sprocket body is difficult to discharge, resulting in poor heat dissipation and abnormal wear of the sprocket and chain. In addition, af...

Problems solved by technology

[0003] The purpose of the present invention is to provide a modular multifunctional sprocket for the poor self-cleaning effect of the sprocket and inconvenient replacement of the sprocket in the prior art. The sprocket adopts intermittent teeth and a modular insert structure , use the distance between the intermittent teeth to form a self-cleaning sewage space, enhance the sewage and self-cleaning effect; and form a sprocket with a replaceable chain tooth structure through the insert structure, so that after the chain teeth are worn or broken, only the corresponding sprockets can be replaced Inserts are enough, there is no need to replace the sprocket as a whole, and it is not necessary to disassemble the chain, thereby improving the convenience of sprocket replacement, achieving the purpose of quick replacement, and significantly saving resources
