A belt is a looped strip of flexible material, used to mechanically link two or more rotating shafts. They may be used as: 1.a source of motion, 2.to efficiently transmit power, 3.or to track relative movement. Belts are looped over pulleys. In a two pulley system, 1.the belt can either drive the pulleys in the same direction, 2.or the belt may be crossed, so that the direction of the shafts is opposite.
