drive pulley belt


In this article, we will discuss the design and working principle of drive pulley, as well as the types and materials of drive pulley. We will also explore the function of the driving pulley, its advantages, the production process, and the difference between a drive pulley and a head pulley. Finally, we will introduce HZPT, a leading manufacturer in the industry.

Design and Working Principle of Drive Pulley

  • The drive pulley is a component of a conveyor belt system that helps transmit power from the motor to the belt.
  • It is typically cylindrical in shape with a central bore for mounting onto a shaft.
  • As the motor rotates the drive pulley, it creates tension in the belt, causing it to move and transport materials.
  • The design of the drive pulley ensures efficient power transmission and minimal slippage.
  • It is crucial for the smooth operation of conveyor systems in various industries.

Types and Materials of Drive Pulley

  • Drive pulleys can be classified into flat-faced, crowned, and lagged pulleys, each serving different purposes.
  • Common materials used for drive pulleys include steel, rubber, and ceramic, depending on the application requirements.
  • Steel drive pulleys are durable and suitable for heavy-duty applications.
  • Rubber drive pulleys offer better traction and are ideal for applications where slippage needs to be minimized.
  • Ceramic drive pulleys are used in specialized industries where corrosion resistance and high wear resistance are crucial.

What is the function of the driving pulley?

  • Transmit power from the motor to the conveyor belt.
  • Create tension in the belt to facilitate material transportation.
  • Ensure efficient power transmission with minimal slippage.
  • Facilitate the smooth operation of conveyor systems in various industries.
  • Contribute to the overall productivity and efficiency of material handling processes.

Advantages of Drive Pulley

  • Efficient power transmission
  • Minimal slippage
  • Durable and long-lasting
  • Low maintenance requirements
  • Wide range of applications

Process of Drive Pulley


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

The molten material is poured into the mold to form the shape of the drive pulley.

Raw Materials

Steel, rubber, or ceramic materials are used based on the application requirements.


The drive pulley is manufactured according to the design and material specifications.


The drive pulley undergoes rigorous testing to ensure quality and performance.

Antirust Treatment

Antirust treatment is applied to prevent corrosion and prolong the lifespan of the drive pulley.

Seperate Inspection

  • Drive pulley transmits power, while head pulley redirects the belt.
  • Drive pulley is connected to the motor, while head pulley is located at the discharge end of the conveyor.
  • Drive pulley is cylindrical in shape, while head pulley may have a crowned or lagged design.
  • Drive pulley is essential for power transmission, while head pulley assists in tracking and alignment of the belt.
  • Drive pulley is typically larger in size compared to the head pulley.
  • Drive pulley is located at the loading end of the conveyor, while head pulley is at the unloading end.
  • Drive pulley is responsible for tensioning the belt, while head pulley helps in belt tracking and alignment.
