Full Gear Coupling FGC 15/ FGC 115 - Gear Coupling

Key Specifications

• Nominal Torque Capacity: 180 kN·m (≈ 180,000 Nm)
• Maximum Speed: 1500 RPM
• Bore Diameter Range (shaft bore): 190 mm – 285 mm
• Outer Diameter (approx.): 780 mm
• Approximate Weight (full‑flex version): 786 kg

How It Works

The coupling consists of two hubs with external crowned gear‑teeth mounted on the driving and driven shafts, plus two outer sleeves with matching internal gear‑teeth. As the driving shaft rotates, torque is transmitted via the meshed teeth through the sleeves to the driven shaft. The crowned‑tooth profile and flexible gear‑sleeve design allow the coupling to compensate for angular, parallel, and axial misalignments — ensuring smooth power transmission even when the shafts are not perfectly aligned. Proper lubrication (grease or oil) is required for long service life.

Benefits

• High torque capacity: Suitable for heavy‑duty industrial applications requiring large torque transmission.
• Misalignment tolerance: Accommodates angular, parallel and axial misalignments, reducing stress on shafts and bearings under load or thermal shifts.
• Shock and vibration absorption: The flexible gear‑coupling design helps absorb shock loads and reduce vibration under heavy or fluctuating loads.
• Durability and long service life: Robust forged or cast‑steel hubs and sleeves with hardened, precision‑machined gear‑teeth ensure reliable performance under demanding conditions.
• Compact design for its capacity class: Despite its very high torque rating, coupling remains relatively compact compared to alternatives for similar torque class.
• Maintenance‑friendly (with correct lubrication): Requires periodic lubrication; with proper maintenance, ensures long and stable service life.

Typical Applications

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

Selection & Installation Considerations

• Ensure driven machine’s power requirement and peak load demand align with coupling’s torque capacity (~ 180 kN·m for FGC 15).
• Verify shaft bore diameters to be within 190–285 mm for compatibility with FGC 15.
• Confirm shaft speed (RPM) does not exceed 1500 RPM for safe operation.
• Allow sufficient space for coupling’s outer diameter (≈ 780 mm) and account for misalignment tolerances during installation.
• Use recommended lubricant (grease or oil based on temperature) — periodic lubrication is critical for smooth operation and service life.
• Consider operating environment — heavy loads, shock, vibration, potential shaft misalignment — where robust coupling like FGC 15 is particularly suitable.

Summary

Full Gear Coupling FGC 15 delivers a powerful, heavy‑duty coupling solution — capable of transmitting high torque (~ 180 kN·m), supporting large shaft bores (190–285 mm), and operating up to 1500 RPM. Its flexible gear‑sleeve design provides misalignment compensation (angular, parallel, axial), shock and vibration absorption, and dependable durability under harsh industrial conditions. With proper installation, alignment, and maintenance (especially lubrication), FGC 15 ensures reliable, long‑lasting performance — ideal for steel mills, cement plants, mining equipment, heavy conveyors, crushers, pumps/compressors, and other demanding heavy‑load machinery.
