What is an epicyclic drive?

Epicyclic drive, also known as planetary gear system, is a gear transmission mechanism that consists of one or more planetary gears rotating around a central sun gear, while the planetary gears also roll inside an internal ring gear or annular gear. This design gives the planetary gear system unique mechanical properties and a wide range of applications.

Characteristics of epicyclic drives


Compact Design

Epicyclic drives are known for their compactness. The arrangement of the sun gear, planet gears, and ring gear allows for a high torque transmission in a relatively small space. This makes them ideal for applications where space is limited.


High Torque Density

Due to the multiple points of contact within the gear system, epicyclic drives can transmit high torque levels. The load is shared among several gears, which enhances the torque capacity without increasing the size of the drive significantly.


High Efficiency

Epicyclic drives operate with high efficiency due to the reduced friction and balanced load distribution. This makes them suitable for applications requiring efficient power transmission.


Multiple Gear Ratios

Epicyclic drives can provide a variety of gear ratios within the same system. By altering the input and output configuration (e.g., fixing the ring gear, planet carrier, or sun gear), different speed and torque outputs can be achieved.


Low Backlash

Epicyclic drives typically exhibit low backlash due to their precise gear engagement. This feature is crucial in applications requiring high positional accuracy and minimal play in the gear system.


Low Maintenance Requirements

Due to their efficient design and load distribution, epicyclic drives often require less maintenance compared to other gear systems. This reduces downtime and operational costs.

The main components of an epicyclic drive

Sun Gear

The sun gear is the central gear around which the planet gears rotate. It is typically the input gear and is driven by an external power source.

Planet Gears

Planet gears are multiple gears that surround and mesh with the sun gear. These gears rotate around the sun gear and are usually mounted on a movable carrier. The planet gears also mesh with the ring gear, enabling them to distribute the load evenly.

Planet Carrier

The planet carrier holds the planet gears in place and allows them to rotate around the sun gear. The carrier itself can either rotate or remain stationary depending on the specific application and desired gear ratio. The planet carrier typically serves as the output or secondary input in the system.

Ring Gear

The ring gear, also known as the annulus, is a large gear with internal teeth that meshes with the planet gears. The ring gear can either be fixed, driven, or act as an output component, depending on the desired configuration and gear ratio of the system.

Input Shaft

The input shaft is connected to the sun gear or planet carrier and is responsible for transmitting the initial power into the system. The configuration of the input shaft can vary based on the application requirements.

Output Shaft

The output shaft is connected to either the planet carrier or the ring gear, depending on the specific design and desired output. It transmits the final power output from the system to the next component in the powertrain.


Bearings are used to support the rotation of the gears and shafts within the epicyclic drive. They reduce friction and wear, ensuring smooth and efficient operation of the system.

Lubrication System

Lubrication is critical in an epicyclic drive to reduce friction between moving parts, prevent wear and tear, and ensure efficient operation. The lubrication system can include oil baths, grease, or specialized lubricants tailored to the specific application.


The housing encloses the entire epicyclic gear system, providing structural support and protection from external contaminants. It also helps in retaining the lubrication within the system.
