Structural composition: It usually includes an outer wall and an inner wall, forming a cavity between the two, and the outer edge is connected by vertical bars. There are pin holes, middle holes, O-ring grooves, threaded holes, etc. on the outer wall, as well as outer wall ribs and light holes. There are also pin holes and middle holes on the inner wall for installing components such as planetary gear mechanisms.
Working principle: In the planetary gear transmission system of a bulldozer, the sun gear inputs power, and the planetary gear meshes with the sun gear and inner ring gear simultaneously. The planetary carrier rotates with the movement of the planetary gear, ultimately outputting power. Through this method, the transmission of power and the transformation of speed and torque are achieved.

Common types include integral frame structure, welded structure and cast structure, cantilever structure with detachable side panels, integral structure with single-sided planetary axle cantilever, and composite structure.
Characteristics: It has high transmission efficiency and can reduce power loss in meshing transmission. At the same time, the structural design enables it to have a large load-bearing capacity, withstand large moments and vibrations, and have small external dimensions and light weight, ensuring even distribution of loads between the planetary gears.
application
Application in the final drive of bulldozers: The final drive is located on the left and right sides of the rear axle box housing of the bulldozer, and the planetary carrier is an important component of the planetary gear structure of the final drive. It is connected to the sprocket hub through bolts, and then drives the track through the gear blocks on the sprocket hub to control the bulldozer to move forward or backward, effectively reducing the load impact of the final drive.

Application in bulldozer transmission system: During bulldozer operation, the output torque and speed need to be adjusted according to different working conditions. The planetary carrier is a key component in the planetary gear transmission system. By cooperating with different clutches, the output steering and speed of the planetary gear set can be controlled to meet the operational needs of the bulldozer under different working conditions.
The planetary carrier has the advantages of high transmission efficiency and strong load-bearing capacity, and can adapt to the complex load and impact environment during bulldozer operation. Its processing technology involves precision gear machining, heat treatment, and assembly technology to ensure the meshing accuracy with the planetary gear and inner ring gear
• Supporting the planetary gear: providing support for the planetary gear to stably mesh and drive around the sun gear and ring gear, ensuring the normal operation of the planetary gear system.

• Power transmission: In the transmission system of bulldozers, the planetary carrier is a key component for power output. Usually, power is input from the sun gear, and the planetary gears rotate around the sun gear and mesh with the ring gear. Finally, the planetary carrier outputs power to drive the track and other components, controlling the bulldozer to move forward or backward.
Ensure transmission accuracy: The manufacturing and installation accuracy of planetary carriers have a significant impact on the meshing quality of planetary transmissions. High precision planetary carriers can ensure even distribution of loads between planetary gears, reduce gear transmission bias, and improve the life and reliability of planetary gears.
• Load bearing: As a load-bearing component, the planetary carrier must withstand various forces and moments generated during the planetary gear transmission process, and its strength and rigidity directly affect the stability and reliability of the transmission system
