With advanced manufacturing capabilities and strong engineering expertise, we provide precision-engineered girth gears designed for high load-bearing capacity, smooth operation, and long service life.

Our Rotary Kiln Girth Gear solutions are suitable for different kiln capacities including 50 TPD, 100 TPD, 200 TPD, 350 TPD, 500 TPD, and 900 TPD rotary kilns, making them ideal for both medium and large-scale industrial operations.


What is a Rotary Kiln Girth Gear?

A Rotary Kiln Girth Gear is a large circular gear mounted around the outer circumference of the rotary kiln shell. It is one of the most critical components in the kiln drive system.

The girth gear works in combination with a pinion gear, which is connected to the motor and gearbox. When the pinion rotates, it drives the girth gear, which in turn rotates the entire kiln.

In simple terms:
👉 Motor → Gearbox → Pinion Gear → Girth Gear → Kiln Rotation

At OP Engineering Group, we manufacture Rotary Kiln Girth Gear with high precision tooth profiles to ensure smooth power transmission, reduced vibration, and efficient kiln operation.


Function of Girth Gear in Rotary Kiln

The Rotary Kiln Girth Gear plays a vital role in the overall performance of the kiln system. Its primary function is to transmit rotational force from the drive system to the kiln shell.

Key functions include:

  • Transmitting power from motor to kiln
  • Ensuring smooth and controlled rotation
  • Handling heavy loads and torque
  • Maintaining synchronization with pinion gear
  • Reducing vibration and mechanical stress

Whether it is a 50 TPD kiln or a 900 TPD large-scale plant, a high-quality Rotary Kiln Girth Gear ensures reliable and efficient operation.


Gear Basics – Understanding Girth Gear

To understand the importance of a Rotary Kiln Girth Gear, it is essential to know how gears work.

A gear is a rotating mechanical component with teeth that mesh with another gear to transmit torque and motion. In rotary kilns:

  • The girth gear is the large driven gear
  • The pinion gear is the smaller driving gear
  • The interaction between them controls kiln speed and rotation

Important gear parameters include:

  • Module – Defines the size of gear teeth
  • Number of Teeth – Determines gear ratio
  • Pitch Diameter – Affects torque transmission
  • Material Grade – Impacts strength and durability

At OP Engineering Group, we design gears with optimized tooth profiles to ensure maximum efficiency and long life.
