They may be used as a source of motion, to efficiently transmit power, or to track relative movement. Belts are looped over pulleys. In a two pulley system, the belt can either drive the pulleys in the same direction, or the belt may be crossed, so that the direction of the shafts is opposite.

Selection of V-Belts Power to be transmitted Speed of the small or large pulley Speed ratio Field of application. Approximate distance between the centres of the two pulleys Steps of V-belts Selection: Determine the service factor Based application, table (5.2). Obtain the design power from the equation: Design power = transmitted power x service factor Select a suitable belt size from fig.(5.3)
