A Planetary Gear is used within the swing drive, providing the necessary torque amplification and smooth operation. When power is transmitted to the swing drive, the sun gear receives rotational input, typically from a hydraulic motor or an electric motor. As the sun gear rotates, it drives the planet gears, which in turn rotate around the sun gear. The planet gears also engage with the internal teeth of the ring gear, causing the ring gear and the entire swing housing to rotate.
