Full Gear Coupling FGC 14A/ FGC 114A - Gear Coupling

Key Specifications

• Maximum Torque Capacity: ~ 455,000 Nm
• Outer Diameter (approx.): 780 mm
• Suitable Shaft / Bore Diameter Range: approx. 230 mm – 360/400 mm (or as per custom bore‑sleeve matching)
• Rated Speed (max): ~ 1,350 RPM

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 gear‑teeth. As the driving shaft rotates, torque is transmitted through the meshed teeth to the driven shaft. The crowned‑tooth profile and flexible gear‑sleeve design allow the coupling to tolerate angular, parallel, and axial misalignments — ensuring smooth power transmission even when shafts are not perfectly aligned.

Benefits

• Very high torque transmission: Suitable for extremely heavy‑duty and high‑load industrial applications.
• 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 forged / cast‑steel hubs and sleeves with hardened, precision‑machined gear teeth ensure reliable performance under demanding conditions.
• Compact for its capacity class: Despite very high torque capacity, coupling remains comparatively compact relative to alternative solutions for similar torque ratings.
• Maintenance‑friendly (with proper lubrication): With correct lubrication and regular inspection, the coupling can deliver long-term, stable operation in heavy‑duty environments.

Typical Applications

• Rolling mills, large‑scale steel / metal‑industry drives requiring high torque and heavy loads
• Cement plants, heavy crushers, large conveyors, and bulk material‑handling equipment
• Heavy pumps, compressors, blowers, large‑scale fans, mixers and other continuous or high‑load machinery
• Mining equipment, aggregate handling systems, and other rugged industrial drives with high torque requirements and potential shaft misalignment or heavy shock loads
• Any heavy‑load industrial machinery demanding very high torque transmission with flexibility and reliability under severe operating conditions

Selection & Installation Considerations

• Ensure the driven machine’s power requirement and peak load demand match the coupling’s torque capacity (~ 455,000 Nm).
• Verify shaft bore diameters and shaft dimensions are compatible (approx. 230–360/400 mm bore, or custom‑bore‑sleeve as per requirement) for FGC 14A.
• Confirm shaft speed does not exceed rated speed (~ 1,350 RPM) for safe operation and longevity.
• Allow sufficient space for coupling’s outer diameter (~ 780 mm) and ensure correct alignment and installation tolerances during assembly.
• Plan for proper lubrication (grease or oil depending on service conditions) and regular maintenance to ensure smooth operation and long service life.
• Consider operating environment: heavy loads, possible misalignment, shocks, vibration — coupling’s robust design and flexibility make it suitable for such demanding industrial conditions.

Summary

Full Gear Coupling FGC 14A provides a top-tier, heavy‑duty coupling solution capable of transmitting up to ~ 455,000 Nm torque, supporting large shaft/bore diameters, with a reasonable maximum rotational speed (~ 1,350 RPM). Its flexible gear‑sleeve design allows angular, parallel, and axial misalignment absorption, making it ideal for large‑scale industrial drives: steel mills, cement plants, mining equipment, heavy conveyors, crushers, pumps/compressors, and other heavy‑load machinery. With correct installation, alignment, and lubrication/maintenance, FGC 14A ensures reliable, long‑lasting power transmission under the most strenuous industrial conditions.
