Introduction to Epicyclic Gearbox
In an epicyclic or planetary gear train, several spur gears are distributed evenly around the circumference, operating between a gear with internal teeth and a gear with external teeth on a concentric orbit. The circulation of the spur gear occurs in a manner analogous to the orbiting of planets in the solar system, which is how planetary gears got their name.
Main Components of a Planetary Gear Train
The components of a planetary gear train can be divided into four main constituents. The housing with integrated internal teeth is known as a ring gear. Typically, the casing is fixed. The driving sun pinion is at the center of the ring gear and is coaxially arranged in relation to the output. The sun pinion is usually mounted on a clamping system to provide the mechanical link with the engine shaft.
During operation, the planetary gears, which are installed on a planetary carrier, roll between the sun pinion and the ring gear. Moreover, the planetary carrier also represents the output shaft of the gearbox. The only purpose of the planetary gears is to transfer the required torque. The number of teeth does not affect the transmission ratio of the gearbox, and the number of planets can also vary.

As the number of planetary gears increases, the distribution of the load increases, thus enhancing the torque that can be transmitted. Increasing the number of tooth engagements also reduces the rolling power. Since only part of the total output needs to be transmitted as rolling power, a planetary gear is extremely efficient. The advantage of a planetary gear compared to a single spur gear lies in this load distribution. Hence, it is possible to transmit high torques with high efficiency using a compact design with planetary gears.
Перавагі планетарных рэдуктараў
Planetary gearboxes have several advantages, including the coaxial arrangement of the input shaft and output shaft, load distribution to several planetary gears, high efficiency due to low rolling power, and nearly unlimited transmission ratio options due to a combination of several planet stages. They are suitable for use as an overriding gearbox and offer a favorable volume output.
