Planetary gears are a key part of the swing mechanism. They consist of a central sun gear, multiple smaller planet gears that orbit around the sun gear, and an outer ring gear. As power is applied to the sun gear, it is transmitted through the planet gears to rotate the outer ring gear. This rotation of the outer ring gear is what causes the upper structure of the excavator to swing. Proper spacing and alignment of these gears are critical for maintaining the precision and efficiency of the swing motion.
