The transmission shaft is a key component for mechanical power transmission. In terms of manufacturing, it is mostly made of 45 steel or alloy steel tubes. It undergoes forging and heat treatment to enhance its strength, and then is processed through precise turning and milling for the critical interfaces. Some parts may also be treated with chrome plating or spray painting for rust prevention, ensuring its wear resistance and torsion resistance during high-speed rotation.
In terms of application, it is widely used in automotive and construction machinery fields. In automobiles, it connects the transmission and the drive axle, transmitting the engine power to the wheels; in loaders, cranes and other equipment, it cooperates with the universal joint to adapt to multi-angle power transmission, ensuring the stability of mechanical operations in complex working conditions.
