Chain

Classification of sprockets

The sprocket is divided into a driving sprocket and a driven sprocket. Driven sprocket: it is mounted on the engine output shaft in the form of a spline; driven sprocket: it is mounted on the drive wheel of a motorcycle and transmits power to the drive wheel through a chain. Generally speaking, the driving sprocket is smaller than the driven sprocket, which can reduce the speed and increase the torque.

Performance characteristics of sprocket

1. Material selection: Both large and small sprocket wheels are stamped and formed with high-quality carbon structural steel.

2. Processing and processing technology: It adopts advanced milling tooth processing technology to make the tooth shape more accurate; and the whole is subjected to quenching and tempering heat treatment, which greatly improves its comprehensive mechanical properties.

Disassembly and assembly of sprocket

1. The driving sprocket is combined with the engine output shaft in the form of a spline, and is fixed with a spline baffle or a nut. When disassembling, you can first remove the sprocket cover, then remove the chain, and finally unscrew the spline baffle or fixing nut to pull the small sprocket out.

2. When the driven sprocket is disassembled, it is necessary to first support the main support frame to raise the rear wheel; then loosen the rear wheel shaft fastening nut and adjuster nut, and remove the chain box and chain; Move the pull rod to pull the rear wheel assembly together; finally remove the bolt, nut or retaining ring that fixes the sprocket.

Sprocket installation requirements and precautions

Installation requirements: Correctly select the sprocket model according to the specifications; check whether the position of the installed sprocket is in good condition, otherwise it must be repaired or replaced; after installing the chain and adjusting the tightness, check whether the chain and the sprocket cooperate smoothly.

Note: The driven sprocket should have anti-loosening measures; after the driven sprocket is loaded, the rear wheel axle should be adjusted by using the adjuster and the rear cradle engraving line. This can prevent the rear wheel from drifting and avoid the chain. Early wear of the wheel and chain; it is best to replace the sprocket and chain at the same time. If only one of them is replaced, the wear and tear on both sides will be aggravated; the chain and sprocket should be cleaned and lubricated regularly to improve its service life.
