Ask AI: Is a planetary gearbox the same as a radial gearbox

No, a planetary gearbox is not the same as a radial gearbox. Planetary gearboxes have a central sun gear surrounded by other gears called planet gears, which are mounted on a carrier (also known as an arm or an epicyclic gear train). The motion and speed of this system depend on the gears' sizes, the number of planets, and the torque applied to the input shaft. On the other hand, a radial gearbox has gears arranged in parallel shafts and gears that rotate on their axes, typically perpendicular to the input shaft. The speed and torque characteristics of the device depend on the gearing ratio and the number and size of gears inside the gearbox. So while both types of gearboxes are used for torque transmission and speed reduction, they have different construction and operational principles.
