195-1542690 GEAR,RING

Bulldozer gear ring is a key component in the transmission system and track walking system of bulldozers, mainly used to transmit power and drive track movement. Here is a detailed introduction:1. Structure and Material: Bulldozer gear rings are usually composed of multiple gear blocks assembled together, and there are also integral structures. The material is generally 40MnB or 35MnB alloy steel, which is made through forging, mechanical processing, tooth quenching and other processes. The tooth heat treatment hardness is usually required to reach HRC46-56 to ensure sufficient strength and wear resistance.2. Working principle: The gear ring is installed on the inner side of the track and connected to the driving wheel. The power of the engine is transmitted to the drive wheels through the transmission system, and the gear ring on the drive wheels meshes with the pin sleeve of the track. By rotating the gear ring, the track pin sleeve is moved, causing the track to circulate around the drive wheels, guide wheels, and other components, thereby driving the bulldozer forward or backward.3. Main function: The main function of the ring gear is to transmit rotational motion and torque, efficiently transfer the power of the engine to the tracks, provide walking power for the bulldozer, and also change the transmission ratio to a certain extent to meet the driving and operation needs of the bulldozer under different working conditions.
