1.Power Initiation: Transmits power from the hydraulic motor to the planetary gear set, starting the torque amplification process. Without a functional sun gear, the gearbox cannot receive or distribute motor power.
2.Torque Foundation: Its tooth count and size determine the gear set’s reduction ratio—directly influencing how much torque is amplified for swing/travel. A properly sized sun gear ensures the excavator has enough force to lift heavy loads or traverse rough terrain.
3.Smooth Operation: Precision-machined teeth ensure quiet, efficient meshing with planet gears, reducing operator fatigue and extending the life of other planetary components (e.g., planet gears, carrier, ring gear).
