What is a sprocket?

A sprocket is a wheel with teeth or cogs that mesh with a chain, belt, or other flexible material to transmit torque or motion. Sprockets are often used in machinery to transfer power or motion between a motor or engine and a drive system such as a conveyor belt, bicycle chain, or gear train. They come in various sizes, shapes, and materials, and can be made of metals, plastics, or other materials, depending on their intended application. Some common types of sprockets include spur, bevel, worm, rack, and roller chain sprockets. Proper maintenance and lubrication are important for ensuring smooth and efficient operation of sprockets.
