PLANETARY GEAR Meaning and
Definition
-
A planetary gear, also known as an epicyclic gear system, is a specialized type of gear mechanism commonly used in various applications that require high gear reduction ratios and compact designs. It consists of a central gear, known as the sun gear, which is encircled by multiple smaller gears, referred to as planet gears. These planet gears are connected to a separate gear, known as the ring gear, which encloses the entire system.
The configuration of gears in a planetary gear system enables the transmission of torque and rotational motion in a unique manner. As the central sun gear rotates, it engages the planet gears, causing them to revolve around the sun gear while also rotating on their own axes. The planet gears are also engaged with the ring gear, resulting in additional rotations. This arrangement allows for multiple output speeds and torque distributions.
Planetary gears offer several advantages, including high gear reduction ratios, increased torque, and compactness compared to traditional gear systems. They are commonly used in automotive applications, such as automatic transmissions, where they provide the ability to shift between multiple gears smoothly and efficiently. Additionally, they are utilized in various industrial machines, robotics, and aerospace systems to transmit motion and torque effectively while maintaining a small form factor.
Overall, a planetary gear is a gear system consisting of a central sun gear, surrounded by a series of planet gears, that are connected to a ring gear. This configuration enables efficient transmission of torque, multiple speed options, and compact design, making it suitable for a wide range of applications.

Etymology of PLANETARY GEAR
The word "planetary" in "planetary gear" derives from the planetary system, which refers to the system of planets revolving around the sun in astronomy. The term was first used to describe a specific type of gear system based on its resemblance to the arrangement of planets in the solar system. This gear system consists of three main components: a central gear known as the sun gear, an outer ring with internal teeth known as the ring gear or annulus, and multiple gears located between the sun gear and the ring gear known as planet gears. These planet gears are fixed to a carrier, which rotates around the central gear, similar to how planets orbit a sun. Hence, the name "planetary gear" was coined due to its resemblance to the planetary system in terms of the relative motion of the gears.
