Product Description:

The excavator planetary gear assembly, also known as the planetary gear set or planetary gearbox, is a key component in the power transmission system of an excavator. It consists of multiple gears arranged in a planetary configuration, allowing for efficient torque transfer and speed reduction or increase.

The planetary gear assembly typically includes the following components:

1.Sun Gear: The sun gear is the central gear in the assembly and is usually driven by the excavator's engine or hydraulic motor. It provides the input power to the gear system.

2.Planet Gears: The planet gears are smaller gears that rotate around the sun gear. They are mounted on a carrier and mesh with both the sun gear and the ring gear. The planet gears distribute the torque and power throughout the system.

3.Carrier: The carrier is a central component that holds the planet gears and allows them to rotate. It provides support and maintains the proper spacing between the gears. The carrier may also have bearings or bushings for smooth rotation.
