Premium Transmission Helical Gearbox
A Helical Gearbox is a precision-engineered industrial gear reducer designed to transmit high torque efficiently and smoothly across demanding applications. Known for its durability, energy efficiency, and quiet operation, the helical gearbox is widely used in heavy-duty machinery where continuous performance and reliability are critical.
At AV Drive Tech, Chennai, we supply industrial helical gearboxes with a power range up to 5500 kW and reduction ratios up to 650:1, supporting large-scale industrial operations across India.
Description
What is a Helical Gearbox?
A helical gearbox uses angled (helical) gear teeth that engage gradually rather than abruptly. This design ensures smoother torque transmission, reduced vibration, and higher load capacity compared to spur gear systems.
A helical gearbox is an industrial gear reducer that uses angled gear teeth to transmit power smoothly, efficiently, and with high torque capacity.
Technical Range & Specifications
Our Helical Gearbox range includes:
- Power Capacity: Up to 5500 kW
- Reduction Ratio Range: Up to 650:1
- Centre Distance Range: 125 mm to 900 mm
These specifications make it suitable for both medium-duty and extremely heavy-duty industrial applications.
Key Features & Engineering Advantages
High Power Handling Capability
Designed to support applications up to 5500 kW, making it ideal for heavy industrial drives.
Wide Reduction Ratio Range
Reduction ratios up to 650:1 provide controlled speed reduction while maintaining torque stability.
Superior Efficiency
Helical gear design ensures higher efficiency compared to worm gearboxes, especially in high-load applications.
Smooth & Quiet Operation
The gradual tooth engagement reduces vibration and noise — ideal for continuous-duty environments.
Compact & Robust Construction
Centre distances from 125 mm to 900 mm allow flexible installation across different plant layouts.
Designed for Heavy Industrial Loads
Manufactured using high-grade materials to withstand shock loads, continuous duty cycles, and harsh working environments.
Why Choose a Helical Gearbox Over Other Gear Types?
Higher Efficiency Than Worm Gearboxes
Helical gear systems have rolling contact rather than sliding contact, reducing friction losses.
Suitable for High-Power Applications
Unlike worm gearboxes, helical gearboxes maintain efficiency even in large-scale industrial drives.
Better for Continuous Operation
Ideal for plants operating 24/7, such as cement plants, mining operations, and power generation facilities.
Major Industrial Applications
Helical gearboxes are widely used in:
- Agitators
- Conveyors
- Crushers
- Cranes
- Larger Ball Mills
