Introduction to Drive Pulley

drive pulley

Design and Working Principle of Drive Pulley

  • The drive pulley is designed to transmit power from the motor to the belt in a conveyor system.
  • It typically has a larger diameter than other pulleys to increase the belt’s contact area for better power transmission.
  • Its design ensures maximum grip on the belt to prevent slipping during operation.
  • The drive pulley works on the principle of friction between the belt and the pulley surface to transfer power efficiently.

  • It is crucial for maintaining smooth and continuous operation of the conveyor system.

Types and Materials of Drive Pulley

Types and Materials of Drive Pulley

  • Drive pulleys can be classified into welded hub pulleys, XT hubs, and QD hubs based on their construction.
  • Common materials used for drive pulleys include steel, stainless steel, and aluminum, depending on the application requirements.
  • Steel drive pulleys are known for their durability and strength, making them suitable for heavy-duty applications.
  • Stainless steel drive pulleys offer corrosion resistance, ideal for environments with moisture or chemicals.
  • Aluminum drive pulleys are lightweight and suitable for applications where weight is a concern.

What is the function of the driving pulley?

Process of Drive Pulley


The mold is created based on the design specifications to form the shape of the drive pulley.

spa pulley


The molten material is poured into the mold to solidify and form the drive pulley.

raw materials

The selected materials are prepared and used for casting the drive pulley.


The drive pulley is manufactured according to the specific requirements and standards.


Quality control tests are conducted to ensure the drive pulley meets performance standards.

Antirust treatment

The drive pulley is treated to prevent corrosion and enhance longevity.

seperate inspection

Each drive pulley undergoes individual inspection to verify quality and performance.


Drive pulleys are marked with essential information for identification and tracking.

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

  • Drive pulleys transmit power to move the belt, while head pulleys redirect the belt’s path.
  • Drive pulleys are located at the conveyor’s discharge end, while head pulleys are at the conveyor’s loading point.
  • Drive pulleys are powered by motors, while head pulleys are passive and guide the belt.
  • Drive pulleys have a larger diameter for better power transmission, while head pulleys vary in size based on application.
  • Drive pulleys are essential for conveying systems, while head pulleys primarily redirect belt movement.
