A planetary stage, which is found within a planetary gearbox Planetary Gearbox A planetary gearbox is a compact gearbox that offers high power density and efficient power transmission. , consists of a central sun gear, several orbiting planet gears, a surrounding ring gear, and a planet carrier. This configuration allows for compact dimensions, balanced load distribution, and high torque density. Depending on the design, a planetary stage can reduce or increase rotational speed and torque. Because multiple gear engagements occur simultaneously, planetary stages are highly efficient and are commonly used in industrial gear units, automotive transmissions, wind turbines, and test systems Test Systems Test systems evaluate the functionality, load capacity and wear of technical components under realistic conditions. . Multiple planetary stages can be combined to achieve higher transmission Transmission The function of a vehicle transmission is to adjust the torque and speed, and to transfer engine power to the drive wheels. ratios or more complex mechanical functions.
