Drum Gear Couplings for Heavy Duty Industrial Applications

Acoplamientos para tambores are widely used in crane systems and industrial machinery for torque transmission and shaft connection. Designed with a compact structure and high load capacity, they are ideal for low-speed, heavy-duty working conditions.

These couplings provide reliable performance in demanding industries such as metallurgy, mining, and lifting equipment, ensuring stable operation and long service life.

Características de diseño y método de conexión

The unique design of drum gear couplings allows for a variable instantaneous transmission ratio, achieved through toothed elements installed between the coupling halves.

Key design features include:

• Ability to accommodate large axial displacement
• Limited compensation for radial and angular misalignment
• Simple structure for easy manufacturing and maintenance

This design ensures efficient torque transmission while maintaining structural simplicity.

Advantages of Drum Gear Couplings

Drum gear couplings offer several advantages for industrial applications:

• Compact structure with small rotational radius
• High load-bearing capacity
• High transmission efficiency
• Low operating noise
• Long maintenance intervals

In addition, the housing is formed through simplified molding processes, reducing manufacturing costs and improving overall reliability.

Applications in Industrial Equipment

Drum gear couplings are widely used in various industrial systems, including:

• Metallurgy and steel production equipment
• Mining machinery
• Lifting and transportation systems
• Hydraulic and lubrication pumps
• Air compressors and pneumatic equipment
• Maquinaria textil

Their versatility makes them suitable for a wide range of operating conditions.

Operating Conditions and Performance

Drum gear couplings are designed to perform reliably within a temperature range of:

-20°C to +80°C

They are available in multiple specifications, offering:

• Up to 28 sizes and 20 types
• Bore diameters up to 1200 mm
• Torque capacity up to 8,191,813 Nm
