A sprocket is a mechanism for transmitting power by winding a chain onto gears or pulleys. The sprocket system works by meshing one or more sprocket pulleys to a chain. This system is often used in applications that require high power transmission capacity.
Chain mechanisms are considered as an intermediate mechanism between gearwheel and belt pulley mechanisms. It creates an advantage to transmit power and motion over long distances.
