Introduction to 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 works on the principle of friction between the pulley surface and the belt, allowing for smooth and efficient power transmission.

Process of Drive Pulley

drive pulley


The drive pulley is first created using a specific mold to ensure accurate dimensions.


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

Raw Materials

High-quality materials are used to ensure the strength and durability of the drive pulley.


The drive pulley is manufactured with precision and attention to detail.


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

Antirust Treatment

The drive pulley is treated to prevent rust and corrosion, extending its lifespan.

Separate Inspection

Each drive pulley is inspected individually to guarantee quality before installation.


Identification marks are added to the drive pulley for easy tracking and maintenance.

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

  • The drive pulley is responsible for transmitting power, while the head pulley redirects the belt.
  • Drive pulleys are connected to the motor, while head pulleys are located at the end of the conveyor system.
  • Drive pulleys are usually larger in size compared to head pulleys.
  • Drive pulleys have a smoother surface for better friction with the belt.
  • Head pulleys may have a lagging to increase traction, while drive pulleys do not.
  • Drive pulleys are essential for power transmission, while head pulleys help in belt tracking.
  • Drive pulleys are more common in conveyor systems, while head pulleys are used for redirection purposes.
