WGP / GICLZ Drum Gear Coupling with Brake Disc – High Torsional Stiffness for Heavy Machinery

Factory direct | S45C steel, keyway type | High torque 4000 N·m | Crowned tooth design

The WGP / GICLZ series is a crowned drum gear coupling with an integrated brake disc (brake disc type) . It is designed for heavy‑duty applications requiring high torque transmission, angular misalignment compensation, and reliable braking.

✅ Ideal for metallurgical equipment, rolling mills, conveyors, and general industrial drives.

Key Technical Specifications (Based on GICLZ / WGP Model)

Six Core Advantages (Based on Factory Data)

Product Features

✅ Crowned (Drum) Gear Design – Superior to Straight Teeth

• Higher load capacity – 15‑20% higher than straight‑tooth gear couplings under same dimensions

• Better contact conditions – eliminates edge loading under angular misalignment

• Reduced wear & noise – extends service life significantly

✅ Large Angular & Eccentricity Compensation

• Allows up to 1° angular misalignment and 1 mm radial eccentricity

• Protects connected equipment from misalignment‑induced damage

✅ Integrated Brake Disc (Brake Disc Type – WGP Style)

• Designed for systems requiring controlled stopping or emergency braking

• Commonly used in cranes, hoists, metallurgical machinery, and conveyors

• Brake disc dimensions can be customized

✅ High Torsional Stiffness & Efficiency

• S45C steel body provides excellent torsional rigidity

• Transmission efficiency 99.7% – nearly lossless power transfer

✅ Easy Maintenance & Assembly

• Bell‑shaped outer gear sleeve makes installation and removal fast and tool‑friendly

• Keyway type shaft locking ensures positive drive without slipping

Applications

• Metallurgical equipment (rolling mills, continuous casting machines)

• Cranes & hoists (with brake disc for emergency stopping)

• Heavy conveyors & bucket elevators

• Mining machinery

• Steel mills & wire rod mills

• Paper & pulp industry

• General industrial drives where angular misalignment exists

Why Choose Apex Coupling for WGP / GICLZ Gear Couplings?

FAQ

Q: What is the difference between WGP and GICLZ?
A: Both are crowned drum gear couplings. WGP typically includes a brake disc (brake disc type) , while GICLZ is the standard drum gear coupling without brake disc. We offer both – please specify your need.

Q: Can I get a custom bore size?
A: Yes. The default bore shown is 50mm, but we can machine any bore with keyway to your drawing.

Q: What is the maximum speed?
A: 4000 rpm for standard models. For higher speeds, please consult our engineering team.

Q: How does crowned tooth improve performance?
A: Crowned teeth maintain line contact even under angular misalignment, avoiding edge stress and reducing wear. This increases load capacity by 15‑20% compared to straight teeth.

Q: Is the brake disc replaceable?
A: Yes. The brake disc can be replaced separately – we supply spare parts.
