Full Gear Coupling FGC 14/ FGC 114 - Gear Coupling

Key Specifications

• Nominal / Maximum Torque Capacity: 380,000 Nm
• Suitable Shaft Bore / Diameter Range: approx. 200 mm (or as per custom bore size matching coupling size)
• Outer Diameter (approx.): 730 mm
• Maximum Shaft Diameter Supported: approx. 370 mm
• Recommended Operating Speed Range: up to ~1,650 RPM (depending on bore and load)

How It Works

The coupling uses two hubs with crowned external gear‑teeth mounted on the driving and driven shafts, and two outer sleeves with matching internal spur‑teeth. As the driving shaft rotates, torque is transmitted through the meshed teeth to the driven shaft. The crowned‑tooth profile and gear‑sleeve configuration allow the coupling to tolerate angular, parallel, and axial misalignments — ensuring smooth power transmission even if the shafts are not perfectly aligned. Proper lubrication (grease or oil) is recommended for smooth functioning and long life.

Benefits

• Very high torque transmission: Suitable for extremely heavy‑duty industrial applications and high load demands.
• Misalignment tolerance: Can accommodate angular, parallel, and axial misalignments — reducing stress on shafts and bearings under load or thermal shifts.
• Shock and vibration absorption: Gear‑coupling design helps absorb shock loads and damp vibrations under heavy or fluctuating loads.
• Durability and long service life: Robust construction (forged/ cast steel hubs and sleeves with hardened, precision‑machined gear teeth) ensures reliable performance under demanding conditions. :contentReference[oaicite:2]{index=2}
• Compact for its capacity class: Despite high capacity, coupling remains relatively compact compared with alternative solutions for similar torque ratings. :contentReference[oaicite:3]{index=3}

Typical Applications

• Rolling mills, steel plants, and heavy‑duty metal‑industry drives
• Cement plants, crushers, heavy conveyors and bulk material‑handling systems
• Pumps, compressors, blowers, large‑scale fans, mixers and other heavy‑duty machinery under continuous or high‑load service
• Mining equipment, aggregate‑handling plants, and other rugged industrial drives requiring high torque and misalignment tolerance
• Any heavy‑load industrial machinery requiring reliable power transmission under significant load, misalignment, or shock/vibration conditions

Selection & Installation Considerations

• Ensure driven machine’s power requirement and peak load match coupling’s torque capacity (≈ 380,000 Nm).
• Verify shaft bore / shaft diameter compatibility as per coupling size (suitable for large shafts up to ~ 370 mm for FGC 14) — adjust bore sleeves accordingly.
• Confirm shaft speed and operating RPM are within safe limits for coupling and application conditions.
• Allow sufficient space for coupling’s outer diameter (≈ 730 mm) and ensure correct alignment and installation tolerances during assembly.
• Plan for proper lubrication (grease or oil as per operating conditions) and regular maintenance to ensure long service life. :contentReference[oaicite:4]{index=4}
• Consider operating environment — heavy loads, misalignment, vibrations — where coupling’s robust design and flexibility will provide reliability and longevity.

Summary

Full Gear Coupling FGC 14 delivers a top‑tier, heavy‑duty coupling solution capable of transmitting up to ~ 380,000 Nm torque, supporting large shaft diameters (up to ~ 370 mm), and providing robust misalignment compensation and shock‑absorption. Its rugged design, high torque capacity, compact footprint relative to capacity, and maintenance‑friendly construction make it ideal for large‑scale industrial drives such as steel mills, cement plants, mining equipment, heavy conveyors, crushers, pumps/compressors, and other demanding heavy‑load machinery. With correct installation, alignment, and regular lubrication, FGC 14 ensures reliable, long‑lasting power transmission in the most strenuous industrial conditions.
