Learning the basics of transmission sprockets

The sprocket is divided into a driving sprocket and a driven sprocket. The driving sprocket is mounted on the output shaft of the engine in the form of splines; the driven sprocket is mounted on the motorcycle driving wheel, and the power is transmitted to the driving wheel through the chain. The driving sprocket is smaller than the driven sprocket, which can reduce the speed and increase the torque.

The performance characteristics of the drive sprocket

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

②Processing and processing technology - using advanced milling technology to make the tooth shape more accurate.The overall sprocket has undergone quenching and tempering heat treatment, which greatly improves its comprehensive mechanical properties. The tooth shape hardness is above 68-72HRA, which significantly improves the wear resistance of the sprocket.The surface has been sprayed and electroplated.

③Product series - economical and practical ordinary sprockets and fine sprockets with superior performance.

Disassembly and assembly of sprocket

1. Active sprocket

The driving sprocket is combined with the engine output shaft in the form of a spline, and is fixed by a spline baffle or a nut.When disassembling, the sprocket cover can be removed, the chain can be removed, and the spline baffle or fixing nut can be unscrewed to pull out the small sprocket.When assembling, proceed in the reverse order.

2. Driven sprocket

① Support the main support frame and tilt the rear wheel.

②Loosen the rear wheel shaft fastening nut and adjuster nut, and remove the chain box and chain.

③ Disassemble the rear brake lever and pull out the rear wheel assembly together.

④ Remove the bolts, nuts or retaining rings that fix the sprocket, and remove the rear hub or pin bolts of the sprocket.

⑤ When installing, proceed in reverse order.And tighten the sprocket fixing nut or bolt (30-50N.M) and the rear axle nut (50-80N.M) according to the specified torque.
