Солнечная шестерня бортового редуктора, 11 зубьев Caterpillar 165-5792

The Final Drive Sun Drive in a final drive assembly refers to the main input gear located at the center of a planetary gear set. It receives rotational force from the drive motor or transmission output shaft and transfers this motion to the surrounding planet gears. The sun drive works as a center element of the final reduction gear system. It helps reduce high-speed, low-torque input from the motor into low-speed, high-torque output for moving loads with precision and power.Attributes:• Transmits torque from the drive motor to planetary gears.• Central component of the planetary gear system.• Facilitates torque multiplication and speed reduction.• Enables smooth and controlled rotation of tracks or wheels.Applications: The Final Drive Sun Drive is found inside the final drive gearbox, mounted on the output shaft of the travel motor, and engages directly with planet gears in the planetary carrier.
