Power transmission belt sheaves or pulleys are used to transfer mechanical power. They include synchronous, timing, v-belt, variable pitch, flat, and round sheaves.  Timing sheaves have external teeth that interlock with the teeth of a timing belt to transmit high torque. Timing belt sheaves are commonly used in automobiles where the timing belt connects the crankshaft and camshaft to control engine valves. Variable pitch sheave systems have one sheave attached to the driving motor shaft and connected to a driven or companion sheave.

  • Timing Pulleys

    Timing Pulleys (1)

    Timing pulleys prevent misalignment and ensure smooth power transfer between the pulley and belt. The pulley has teeth and pockets on the outer surface its body. These teeth and pockets mate with a timing belt with the same pitch to make synchronous drive. The design also provides a higher torque carrying capacity and allows the drive to operate with lower…
  • V-Belt Sheaves

    V-Belt Sheaves (370)

    Power transmission v-belt sheaves are used to transfer mechanical power. They transfer force from motors to pulleys to power a variety of parts including paddles, rollers, water pumps, compressors, and fans. The V shape allows the belt to fit securely in the pulley to prevent side drift and help prevent the belt from turning over. Banded belts have multiple grooves…
  • Variable Pitch Sheaves

    Variable Pitch Sheaves (1)

    A variable pitch sheave has a threaded angular faced discs that forms the V-shaped groove. The v-belt rides in the groove, which are movable. When the discs are moved toward each other, the belt rides higher in the groove and the pitch diameter of the sheave is larger, which increases the driven speed. When the discs are moved away from…
