Vibration of fag bearing and temperature inspection of fag bearing

Vibration of fag bearing,FAG bearing vibration is very sensitive to the damage of fag bearing

Vibration of fag bearing.For example, spalling, indentation, corrosion, crack, wear, etc. will be reflected in fag bearing vibration measurement. Therefore, the vibration can be measured by using a special fag bearing vibration meter (frequency analyzer, etc.), and the specific abnormal conditions can not be inferred by frequency division. The measured values are different due to the service conditions of the fag bearing or the installation position of the sensor. Therefore, it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard.

Temperature of fag bearing

Vibration of fag bearing.Generally, the temperature outside the fag bearing chamber can be inferred. It is more appropriate if the outer ring temperature of the fag bearing can be directly measured by using the oil hole.

Vibration and temperature inspection of fag bearing

The temperature of fag bearing begins to rise slowly with the operation of fag bearing

Vibration of fag bearing.Stable state after 1-2 hours. The normal temperature of fag bearing varies with the thermal capacity, heat dissipation, rotating speed and load of the machine. If the lubrication and installation parts are appropriate, the fag bearing temperature will rise sharply and abnormal high temperature will occur. At this time, the operation must be stopped and necessary preventive measures must be taken.

The thermal sensor can monitor the operating temperature of the fag bearing

Vibration of fag bearing.The thermal sensor can be used to monitor the working temperature of fag bearing at any time, and automatically alarm or stop when the temperature exceeds the specified value to prevent the occurrence of combustion shaft accident.

Vibration and temperature inspection of fag bearing

High temperature often indicates that fag bearing is in abnormal condition

Vibration of fag bearing.High temperatures are also detrimental to fag bearing lubricants. Sometimes fag bearing overheating can be attributed to fag bearing lubricant. If the temperature of fag bearing exceeds 125 ℃ for a long time, the service life of fag bearing will be reduced. The causes of high temperature fag bearings include insufficient or excessive lubrication and lubricant. It contains impurities, excessive load, FAG bearing ring damage, insufficient clearance, high friction caused by oil seal, etc.

Continuous monitoring of fag bearing temperature is necessary

Vibration of fag bearing.Whether measuring fag bearing itself or other important parts. If the operating conditions remain unchanged, any temperature change can indicate that a fault has occurred.

Regular measurement of fag bearing temperature can be made by means of thermometer

Vibration of fag bearing.For example, the digital thermometer can accurately measure the temperature of fag bearing and display it in ℃ or Fahrenheit.

Importance of fag bearings

Vibration of fag bearing.It means that when it is damaged, the equipment will be shut down. Therefore, this kind of fag bearing should be equipped with a temperature detector.Under normal conditions, FAG bearings will have a natural temperature rise after just lubricated or re lubricated and last for one or two days.
