Chain and sprocket drives are often used where positive synchronization between shafts and transmission of substantial torque are required. They are one of the more frequently used methods of power transmission, providing greater power than belts. Highly efficient, a single chain can drive several shafts and is used for both long and short distances. Adverse conditions, such as temperature and environment, do not affect their running. Other advantages include compact size and low maintenance costs. Chain drives are found in a wide range of power transmission applications, including bicycles, agricultural machinery, machine tools, conveyors, business machines, electronic or electro-mechanical devices, etc.
