Common Motor Shaft Failures and Solutions

During the long-term operation of motors, motor shafts may experience various failure issues, with common ones including wear, bending, fracture, and corrosion. Wear typically occurs at the mating surfaces of the shaft and bearings. Insufficient lubrication or the presence of foreign objects can lead to surface damage, affecting rotational accuracy. Bending and fracture are often caused by overload operation, material defects, or improper installation, which can lead to overall motor failure in severe cases. Corrosion problems are common in humid or chemical environments, and prolonged exposure can weaken the strength of the motor shaft. Corresponding solutions can be implemented to address these failure issues.
Firstly, rational design and material selection are crucial, requiring the selection of alloy steel or stainless steel with good strength and toughness. Secondly, good lubrication and maintenance should be ensured during use to avoid dry friction operation. Finally, surface treatments such as chrome plating, carburizing, or nitriding can be used to improve wear resistance and corrosion resistance.
Through scientific prevention and improvement measures, the life and reliability of the motor shaft can be greatly improved, thereby ensuring the stable operation of the motor.
