Introduction to Drive Pulley

Design and Working Principle of Drive Pulley

  • The drive pulley is a key component in power transmission systems.
  • It is designed to transmit power from the driving force to the driven component.
  • By using friction between the belt and the pulley surface, it provides the necessary torque to move the machinery.
  • The design ensures maximum power transmission efficiency and minimal belt slippage.
  • The working principle involves the rotation of the drive pulley, which in turn moves the belt to transfer power.

Types and Materials of Drive Pulley


  • Flat drive pulley
  • Crowned drive pulley
  • Lagged drive pulley
  • Spiral pulley
  • Wing pulley


  • Cast iron
  • Steel
  • Aluminum

What is the difference between a drive pulley and a head pulley?

  • Drive pulley is used to transmit power, while head pulley is used to change the direction of the belt.
  • Drive pulley is connected to the motor, while head pulley is located at the end of the conveyor.
  • Drive pulley is larger in size compared to head pulley.
  • Drive pulley has a higher load-bearing capacity than head pulley.
  • Drive pulley is directly driven by the motor, while head pulley is driven by the belt.
  • Drive pulley is essential for power transmission, while head pulley is crucial for belt alignment.
  • Drive pulley is more common in power transmission systems, while head pulley is more common in conveyor systems.
