What is a planetary gear? Two key points that even new employees can understand [Structure and Principle]
The order in which power is transmitted and the mechanism of deceleration—understanding the "structure" changes your perspective.
In the previous installment, we introduced the theme "What is a Planetary Gear?" in an easy-to-understand manner, covering its purpose and features. This time, as a continuation, we will explain the structure of the planetary gear mechanism and how the reduction is achieved. The planetary gear mechanism consists of three gears: the sun gear, the planet gears, and the ring gear. By fixing one of these, we can create movements such as reduction, reversal, and acceleration. This time, we will focus on the representative "reduction structure with the ring gear fixed" and explain how each gear takes on power and what roles they play. Particularly noteworthy is the complex motion of the planet gears, which both "rotate" and "orbit." This movement is the key to enabling a compact and highly efficient reduction mechanism. By understanding the workings of planetary gears, your perspective on design and selection should change as well.
