“The criteria and treatment methods for judging fault damage of INA supercharger bearing should consider factors such as abnormal noise, vibration, temperature, lubrication, and wear patterns, and appropriate measures such as inspection, repair, or replacement should be taken to ensure safe and reliable operation.”
From the fact that peeling, indentation, corrosion, crack, wear, etc. will be reflected in the vibration measurement of the bearing, the vibration of ina bearing is very sensitive to the damage of the bearing. Therefore, the vibration of supercharger bearing can be measured by using a special bearing vibration meter (frequency analyzer, etc.), and the specific abnormal situation can not be inferred by frequency division. Because the measured values are different due to the service conditions of the bearing or the installation position of the sensor, it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard.
