We have to consider many factors when choosing a sprocket, such as cast iron, stainless steel, carbon steel, nylon, plastic and so on. The scope of application of the product includes industry, automobile, agricultural machinery, reducer, elevator, etc. Types include cylindrical gears, worm gears, bevel gears, helical gears, planetary gears and so on.
In fact, the sprocket is a white wheel with toothed sprocket. It is a solid or spoke tooth cutter wheel, which meshes with a (roller chain) to transmit motion, and the white wheel is used to mesh with a straight body with accurate pitch on the chain link or cable du.
Sprockets are widely used in mechanical transmission in chemical, textile machinery, food processing, instrumentation, petroleum and other industries. The sprocket functions as a timing belt and is an important part of the engine valve system. It is connected with the crankshaft and matched with a certain transmission ratio to ensure the accuracy of the intake and exhaust time.
The function of the sprocket is the ignition sequence (time) of the opening and closing of the valve during the piston stroke (up and down movement) of the engine. Under the "timing" connection, it is necessary to maintain "synchronous" operation at all times. During the working process of the automobile engine, the four processes of air intake, compression, explosion and exhaust occur continuously in the cylinder. The timing of each step must be matched with the movement state and position of the piston to make the intake, exhaust and piston lift. Coordinate with each other. The timing sprocket acts as a "bridge" in the engine, and the power is transmitted to the corresponding parts driven by the crankshaft.
