Planetary_Gear · 模型 182389
This is the design of planetary gear system, also known as an epicyclic gear train, is a compact mechanical assembly consisting of three primary components: a central sun gear, multiple planet gears mounted on a rotating carrier, and an outer ring gear(or annulus) with internal teeth. In this system, the planet gears simultaneously mesh with both the sun gear and the ring gear, orbiting the center like planets in a solar system while rotating on their own axes. By holding one of these three components stationary while using another as the input, the system can achieve various gear ratios and directions, such as significant speed reduction or torque multiplication. This coaxial design is highly efficient because the load is distributed across multiple gear teeth, allowing it to handle high torque in a space-saving package common in automatic transmissions, robotics, and heavy machinery.
