GIICL Drum Gear Coupling – 45# Steel Gear Shaft Connector for Heavy-Duty Power Transmission

Factory Direct | 45# Steel Forged Hubs | H7 Precision Bore | Torque Range 0.4–5000 kN·m | Drum-Shaped Gear Teeth | Customizable

Product Overview

The GIICL Drum Gear Coupling is a heavy-duty power transmission component designed for high-torque, high-speed industrial applications where reliable shaft connection and misalignment compensation are essential. Featuring crowning (drum-shaped) gear teeth, this coupling provides superior angular misalignment capacity compared to straight-tooth gear couplings, while maintaining high torque density and compact dimensions.

Manufactured from high-quality 45# steel forged billets with integral quenched and tempered heat treatment, the GIICL coupling offers excellent hardness, toughness, and wear resistance – ensuring long service life under demanding operating conditions. With H7 precision‑ground bores, black oxide surface finish, and a robust sealed lubrication system, this coupling delivers reliable performance in metallurgical mills, mining equipment, conveyors, paper machinery, and other heavy industrial applications.

Technical Specifications

Model Dimensions – GIICL Series (Representative Selection)

As drum gear couplings are typically customised to shaft sizes and power requirements, dimensions vary by model and bore specification. Below is a general size reference – please contact us with your specific requirements for exact dimensions.

Custom bore sizes, keyways, and overall dimensions available on request. Larger models available – please inquire.

Key Advantages at a Glance

✔ Drum‑Shaped Gear Teeth – Superior angular misalignment capacity; reduces edge loading and tooth stress

✔ 45# Steel Forged & Heat‑Treated – High hardness, excellent toughness, and superior wear resistance

✔ H7 Precision Bore – Accurate shaft fit for high concentricity and vibration‑free operation

✔ Wide Torque Capacity – From 0.4 to 5,000 kN·m – one series for diverse applications

✔ Integral Sealed Design (Optional) – Enhanced lubrication retention, reduced maintenance, improved reliability

✔ Bidirectional Operation – Flexible installation – either side can be input

✔ Black Oxide Finish – Corrosion protection with cost‑effective surface treatment

✔ Full Customisation – Bores, keyways, splines, and flange sizes tailored to your equipment

Drum Gear Design – Technical Advantage

Unlike traditional straight‑tooth gear couplings, the drum‑shaped (crowning) gear teeth of the GIICL series are designed with a spherical tooth profile. This geometry:

• Increases permissible angular misalignment – reduces sensitivity to shaft deflection

• Eliminates edge contact – distributes load evenly across the tooth flank

• Reduces contact stress – extends gear and coupling service life

• Maintains high torque capacity even under misaligned conditions – ideal for long shaft spans and flexible foundations

Applications

The GIICL drum gear coupling is the preferred choice for heavy‑duty power transmission across industries:

• Metallurgical Machinery – Rolling mills, continuous casting equipment, coilers

• Mining Equipment – Conveyors, crushers, mills, hoists

• Cement & Building Materials – Rotary kilns, ball mills, bucket elevators

• Paper & Pulp Machinery – Dryer sections, winders, calenders

• Power Generation – Turbine–generator couplings, coal mills, fans

• Marine Propulsion – Intermediate shaft connections

• Heavy Conveyors – Long‑distance belt conveyors, bucket elevators

• General Heavy Industry – Large compressors, mixers, extruders, and test benches
