  • What is a planetary gearbox Apex Dynamics

    The planetary gearbox got its name because of how the different gears move together. In a planetary gearbox we see a sun (solar) gear satellite (ring) gear and two or more planet gears. Normally the sun-gear is driven and thus move the planet gears locked in the planet carrier and form the output shaft.
