Heavy Duty Gearbox

 

A Cylindrical Gear Reducer is a mechanical transmission device designed to reduce input speed and increase output torque through precision-engineered cylindrical gears. With high efficiency, durability, and smooth operation, it is widely used in heavy machinery, mining, metallurgy, conveyors, and automation equipment.

 

 

1. High Load Capacity

Gears are made of alloy steel (20CrMnTi / 42CrMo), carburized and quenched with surface hardness up to 58–62 HRC, ensuring excellent wear resistance.

Advanced gear tooth design distributes loads evenly, providing 20% higher torque capacity than conventional gearboxes.

2. High Efficiency & Low Noise

Gear accuracy meets ISO 1328 / DIN 6 standards, achieving transmission efficiency of 95–97%.

Helical gear design increases contact ratio, significantly reducing vibration and noise to meet industrial noise control standards.

3. Durable & Reliable Design

Robust housing made from high-strength cast iron (HT250/FC250) with ribbed structure for rigidity and vibration absorption.

Bearings from top brands (SKF/NSK) ensure stability under continuous heavy-duty operation.

4. Flexible Installation & Easy Maintenance

Available in horizontal, vertical, and flange-mounted configurations, adaptable to different layouts.

Modular design simplifies servicing, reducing downtime and maintenance costs.

5. International Standard Compliance

Designed and manufactured according to ISO, DIN, and AGMA standards, ensuring global compatibility.

Each gearbox undergoes 100% noise, backlash, and load testing before shipment.
