Introduction to Drive Pulley

Design and Working Principle of Drive Pulley

  • The drive pulley is designed to transmit power between the motor and the belt system.
  • drive pulley

  • It typically has a larger diameter than other pulleys in the system to provide more surface contact with the belt.
  • The working principle involves the motor rotating the drive pulley, which then moves the belt system to transfer power efficiently.

Each drive pulley undergoes rigorous testing to ensure quality and reliability.

Antirust treatment:

The drive pulley is treated with anti-rust coatings to increase longevity.

Separate Inspection:

Each drive pulley is inspected individually to maintain quality standards.


Final markings are added to the drive pulley for identification and tracking purposes.

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

  • Drive pulley transfers power, while head pulley redirects the belt system.
  • Drive pulley is connected to the motor, while head pulley is connected to the end of the belt system.
  • Drive pulley is larger in size compared to head pulley.
  • Drive pulley is responsible for maintaining tension in the belt system.
  • Head pulley is used to change the direction of the belt system.
  • Drive pulley is located at the beginning of the belt system, while head pulley is at the end.
  • Drive pulley is essential for power transmission, while head pulley is crucial for belt direction changes.
