Power Transmission Systems
Mechanical power transmission involves using different types of systems to transfer energy from one component to another without changing its nature. When motion coming from a driving mechanical component is transferred to another without being changed, there is power transmission. The most common mechanical power transmission methods in use in the engineering industry today are Shaft couplings, Chain drives, Gear drives, Belt drives (industrial & automotive), and Power screws (lead screws).
Belt drives are a common sight in industrial applications. A belt drive system consists of two pulleys and a belt (or rope). The belt transmits power by friction only. The belt drive system can be used for long center-to-center distance of the shaft. For effective transmission, friction between the pulley surface and the belt surface should be as high as possible.
