V belt

Belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. Belts may be used as a source of motion, to transmit power efficiently or to track relative movement.Friction drive belts rely on the friction between the belt and pulley to transmit power. They require tension to maintain the right amount of friction. Flat belts are the purest form of friction drive while V-belts have a friction multiplying effect because of wedging action on the pulley.

Description

  • V-belts, with a trapezoidal or V shape, made of rubber, neoprene, and urethane synthetic materials, replaced flat belts. Now, the increased overall surface material of modern belts adheres to pulley grooves through friction force, to reduce the tension required to transmit torque.
  • A variety of belts, the top left is a grooved flat belt and the rest are variations of V-belts: They are commonly used on automobile engines to drive accessories, such as the power steering pump, the air conditioning compressor, the fan and the alternator.
