Full Gear Coupling FGC 11/ FGC 111 - Gear Coupling

Key Specifications

• Maximum Torque Capacity: 120,800 Nm
• Maximum Speed: 2,100 RPM
• Bore Diameter Range (shaft bore): 110 mm – 260 mm
• Outer Diameter (approx.): 545 mm
• Approximate Weight: 454 kg (full‑flex version)
• Misalignment / Compensation Capability: Flexible gear coupling design allows angular, parallel, and axial misalignment tolerance (within coupling’s engineering limits)

How It Works

The coupling uses two hubs with external crowned gear‑teeth mounted on the driving and driven shafts. These hubs mesh with two outer sleeves having matching internal gear‑teeth. As the driving shaft rotates, torque is transmitted through the meshed teeth to the driven shaft. The crowned‑tooth profile and gear‑sleeve design allow the coupling to tolerate angular, parallel and axial misalignments — ensuring smooth power transmission even if shafts are not perfectly aligned.

Benefits

• Very high torque and power capacity: Suitable for very heavy‑duty industrial applications requiring large torque transmission.
• Misalignment tolerance: Accommodates angular, parallel and axial misalignments, reducing stress on shafts and bearings.
• Shock and vibration absorption: Gear‑coupling design helps absorb shock loads and minimize vibration under heavy or fluctuating loads.
• Durability and long service life: Forged carbon‑steel hubs and sleeves with hardened and precision‑machined gear teeth ensure reliable performance under demanding conditions.
• Compact for its torque class: Offers high torque in a relatively manageable footprint for such capacity.
• Suitable for heavy machinery and industrial drives: Makes it ideal for steel mills, cement plants, conveyors, crushers, pumps, compressors, and other heavy‑load equipment.

Typical Applications

• Rolling mills, steel plants, and heavy‑duty metal‑industry drives
• Cement plants, crushers, conveyors, and heavy material‑handling equipment
• Pumps, compressors, blowers, fans, mixers — heavy‑duty or continuous‑service machinery
• Mining, aggregate‑handling, and other rugged industrial drives with high torque and possible shaft misalignment
• Any heavy machinery requiring reliable power transmission under variable loads, misalignment or harsh operating conditions

Selection & Installation Considerations

• Ensure the driven machine’s power requirement and peak load match the coupling’s torque capacity (~ 120,800 Nm).
• Verify shaft bore diameters to be within 110–260 mm for compatibility.
• Confirm shaft speed does not exceed 2,100 RPM for safe operation.
• Allow sufficient space for coupling’s outer diameter (~ 545 mm) and account for misalignment tolerances during installation.
• Ensure proper lubrication (grease or oil as per operating conditions) and regular maintenance to maximize service life.
• Consider operating conditions: heavy loads, possible misalignment, shocks and vibration — FGC 11 is suitable for such demanding industrial conditions.
