A V-Belt is a belt with tapered sides, used to transmit motion between two pulleys. V-Belts are the most basic belt utilized for power transmission. V-Belts provide traction, speed of movement, load of the bearings, and long service life.

The “V” shape of the V-Belt tracks in a mating groove in a pulley or sheave, with the result that the belt cannot slip. V-Belts are also available with cogs, which further increase their efficiency. Many drive systems utilize multi-grooved sheaves to accommodate multiple V-Belts, depending on drive horse power and torque requirements. Such drives can utilize multiple individual V-Belts or the belts may have a common backing. V-Belts come in five width sizes, are standardized between manufacturers and are available in a number of different lengths.

  • “A”  Top Width = .50”
  • “B”  Top Width = .66”
  • “C”  Top Width = .88”
  • “D”  Top Width = 1.25”
  • “E”  Top  Width = 1.50”

V-Belts are generally considered the least expensive manner in which to transfer power. As V-Belt size and length gets larger, drive efficiencies decrease. Newer belts designs and styles have improved upon the V-Belt and should be considered for more complex drive design.

·Timing Belts

A timing belt is a general term utilized for a type of belting that is flat and has teeth. Timing belts are used to transmit power or to interchange rotary motion and linear motion, where either high loads or maintaining a specific drive ratio are important. Timing belts are also referred to as synchronous belts. When utilized in power transmission, timing belts are much more efficient and quieter than both V belt and chain drive systems. Timing belts are predominantly available in rubber, but timing belts manufactured out of urethane are becoming increasingly popular.

A pulley is a wheel or sheave with a groove designed to fit either a belt, rope or cable. In power transmission, pulleys will most often utilize a belt. A drive utilizing a pulley system is characterized by two or more pulleys in common to a belt. A pulley or belt drive is a method of transferring rotary motion between two shafts. A pulley drive includes one pulley on each shaft and one or more continuous belts over the two pulleys. This allows for mechanical power, torque, and speed to be transmitted across axes and, if the pulleys are of differing diameters, this ratio creates a mechanical advantage.

A pulley drive is similar to a chain or gear drive, except the ratio and speed reduction is accomplished through differing pitch diameters of the pulleys rather than by the number of teeth on a sprocket or gear. The motion of the driving pulley is, generally, transferred to the driven pulley via the friction between the belt and the pulley.  Synchronous/timing belts have teeth and therefore do not depend on friction to transmit motion.

There are many advantages to a pulley or a belt drive:

  • Flexible equipment design
  • Limit shock and vibration
  • Driven shaft speed easily changed by changing pulley size
  • No lubrication
  • Easily maintained
  • Quiet operation
  • Standardized from stock bored to size or bushing style
