It is said that vibration can be quite sensitive to bearing damage. Peeling, indentation, corrosion, cracks and wear will be reflected in the bearing vibration measurement. Therefore, by using a special bearing vibration measuring device to measure the magnitude of the vibration and the frequency distribution to judge the specific abnormal situation of a bearing . The measured value varies depending on the use condition of the bearing or the installation position of the sensor, so it is necessary to analyze and compare the measured value of each machine in advance to determine the judgment standard.
And let's check out how the temperature works on the bearing.
High temperature often indicates that the bearing lies in an abnormal condition,which is also harmful to the lubricant of the bearing. Sometimes bearing overheating can be attributed to the lubricant of the bearing. Long-term continuous rotation of bearings at temperatures exceeding 125°C will reduce bearing life.
Causes of high temperature bearings include: insufficient or excessive lubrication, lubricants. Containing impurities, excessive load, bearing ring damage, insufficient clearance, high friction caused by oil seal, etc.
Therefore, monitor the bearing temperature is necessary, whether it is measuring the bearing itself or the other important parts. If the operating conditions remain unchanged, any temperature change may indicate that a malfunction has occurred.
