Product Overview

The GIICL Drum Gear Coupling is a heavy-duty flexible coupling designed for high-torque industrial applications. Featuring a drum-shaped gear tooth profile, this coupling provides optimized contact area, improved load distribution, and reliable misalignment compensation. Available with an optional brake disc (WGP type) , it is ideal for heavy machinery, metallurgical equipment, and mining applications. The flange connection ensures secure, easy installation, while the carbon steel construction and black oxide finish deliver durability in harsh environments.

Design & Operating Principle

The GIICL drum gear coupling consists of:

• Two gear hubs with drum-shaped external teeth

• Two flanged sleeves with internal teeth

• Optional brake disc (WGP type)

• Seals and lubricant for long service life

How it works:
The drum-shaped gear teeth mesh with the internal teeth of the flanged sleeves, transmitting torque while allowing angular, radial, and axial misalignment. The optimized tooth profile increases contact area, reducing stress and improving load distribution. The flange connection provides a secure, bolted interface for easy installation and maintenance.

Key advantages:

• High torque capacity for heavy industrial loads

• Compensation for radial, angular, and axial misalignment

• Vibration damping for smoother operation

• Overload protection for equipment safety

• Optional brake disc for integrated braking

Applications

• Heavy machinery and equipment

• Metallurgical equipment (rolling mills, cranes)

• Mining machinery (crushers, conveyors)

• Marine propulsion

• Railway traction

• Paper and pulp machinery
