Sprocket: a wheel with inset chain teeth used to engage with a block with an accurate pitch on a pitch chain or cable, a solid or spoke gear that engages with (roller) chains to transfer motion. Sprocket application: it is widely used in chemical industry, textile machinery, food processing, instrument and instrument, petroleum and other industries of mechanical transmission. The sprocket ACTS as a timing belt and is an important part of the engine distribution system. The accurate time of intake and exhaust can be guaranteed by connecting with the crankshaft and matching with a certain transmission ratio.
The effect of timing sprocket is that when the engine runs, the piston stroke (up and down movement) valve opening and closing (time) ignition sequence (time), in the "timing" connection action, always keep "synchronous" operation. Automobile engine working process, the air intake, compression, constantly taking place within the cylinder explosion, four process exhaust, and the timing of each step should be to match the piston motion and position, make the air intake and exhaust and piston lift mutual coordinate, timing chain inside the engine play a "bridge" role, in leads to the crankshaft strength is passed to the corresponding parts.
