The travel final drive consists of a hydraulic motor a gearbox, and a final drive sprocket that connects to the tracks
The hydraulic motor receives high-pressure hydraulic fluid from the excavator's hydraulic system and uses it to turn the gears in the gearbox. The gearbox, in turn, reduces the speed of the motor and increases the torque, which is then transferred to the final drive sprocket to drive the tracks.
The KUBOTA U30 travel final drive has a specific set of specifications designed to ensure optimal performance, including:
Gear ratio: The gear ratio of the travel final drive is crucial in determining the excavator's speed and torque. The KUBOTA U30 travel final drive has a gear ratio of 38.9:1, which provides a good balance of speed and torque for efficient operation.
Maximum torque: The maximum torque of the travel final drive is the amount of rotational force it can generate. The KUBOTA U30 travel final drive has a maximum torque of 6,924 Nm, which is sufficient to provide enough power for the excavator to operate through tough conditions.
Operating pressure: The operating pressure of the travel final drive is the amount of hydraulic pressure required to operate it. The KUBOTA U30 travel final drive operates at a pressure of 32 MPa, which is within the excavator's hydraulic system's operating range.
Oil capacity: The oil capacity of the travel final drive is the amount of oil required to lubricate and cool the internal components
The KUBOTA U30 travel final drive has an oil capacity of 2.6 liters, which is sufficient to maintain optimal operating temperatures.
Weight: The weight of the travel final drive is an essential consideration as it affects the excavator's overall weight and balance. The KUBOTA U30 travel final drive weighs approximately 44 kg, which is within the excavator's weight capacity.
