Introduction to Drive Pulley

Design and Working Principle of Drive Pulley

The drive pulley is a key component in the machinery used for power transmission. It is designed to transmit power from the driving force to the driven component efficiently. The drive pulley usually consists of a central hub and a cylindrical shell, with the belt running around it. The drive pulley works on the principle of friction, where the belt grips the pulley surface and rotates it to transfer power.

Types and Materials of Drive Pulley


  • Flat Drive Pulley
  • Crowned Drive Pulley
  • Wing Drive Pulley


  • Steel Drive Pulley
  • Aluminum Drive Pulley
  • Plastic Drive Pulley

What is the function of the driving pulley?

The function of the driving pulley is crucial in power transmission systems. It serves the following purposes:

    drive pulley

  1. Transmit power from the motor to driven machinery
  2. Maintain proper tension in the belt
  3. Ensure smooth operation of the system
  4. Control the speed ratio between the driver and driven components
  5. Provide torque multiplication
  6. Facilitate direction change in the system

The production process of drive pulleys involves several steps:

  1. Mold design and creation
  2. Casting of the pulley
  3. Selection of raw materials
  4. Production of the drive pulley
  5. Testing for quality control
  6. Antirust treatment
  7. Separate inspection
  8. Marking for identification

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

The main differences between a drive pulley and a head pulley are:

  1. Drive pulley receives power from the motor, while the head pulley transfers power to the driven machinery.
  2. Drive pulley is usually larger in size compared to the head pulley.
  3. Drive pulley is connected to the motor shaft, whereas the head pulley is connected to the driven component.
  4. Drive pulley controls the speed and direction of the system, while the head pulley maintains tension in the belt.
  5. Drive pulley is located at the input end of the system, while the head pulley is at the output end.
  6. Drive pulley is responsible for torque multiplication, whereas the head pulley ensures smooth operation.
  7. Drive pulley is essential for power transmission, while the head pulley assists in belt tracking.
