Premium Transmission Planetary
A Planetary Gearbox (also known as an epicyclic gearbox) is a high-performance power transmission system engineered for extremely high torque capacity within a compact footprint. Designed for heavy-duty industrial operations, it ensures smooth co-axial torque transmission, superior efficiency, and minimal backlash.
At AV Drive Tech, Chennai, we supply industrial planetary gearboxes with torque capacity up to 4072 kNm, serving cement plants, mining units, sugar mills, cranes, and other high-load industries across India.
Description
What is a Planetary Gearbox?
A planetary gearbox consists of a sun gear, multiple planet gears, and a ring gear, arranged in a compact epicyclic gear train. These gears rotate on parallel axes to transmit power co-axially (input and output shafts aligned).
A planetary gearbox is a compact epicyclic gear system where sun, planet, and ring gears transmit high torque co-axially with high efficiency and minimal backlash.
Technical Range & Capability
Torque Capacity: Up to 4072 kNm
Gear Arrangement: Epicyclic (Sun–Planet–Ring)
Input & Output Alignment: Co-axial (same line)
Reduction Capability: Very high reduction ratios possible
Backlash: Minimal
This design allows extremely high torque transmission in a compact form compared to other gearbox types.
Key Engineering Advantages
High Torque Density
Delivers exceptional torque output relative to size — ideal for heavy-duty industrial drives.
Compact & Space-Efficient
Smaller footprint compared to helical or worm gear systems handling similar torque.
Very High Efficiency at All Ratios
Rolling contact between gears ensures consistent efficiency across various load conditions.
Co-Axial Shaft Alignment
Input and output shafts are aligned, simplifying system integration and reducing structural complexity.
Minimal Backlash
Ensures precision in applications requiring controlled motion and torque stability.
Low Noise & Smooth Operation
Balanced gear load distribution reduces vibration and operational noise.
Durable Construction
Designed to handle heavy loads and harsh industrial environments.
Skilled Maintenance Requirement
Due to its precision construction, maintenance should be performed by skilled personnel.
Why Choose Planetary Gearbox Over Other Gear Types?
Higher Torque in Smaller Size
Compared to worm or helical gearboxes, planetary systems deliver significantly higher torque density.
Better Load Distribution
Multiple planet gears share the load, reducing wear and extending service life.
Ideal for Heavy Continuous Operation
Commonly used in cement mills, mining drives, and sugar mills where torque demand is extreme.
