Use the sound of the size and sound quality of the sound equipment to check the operation of the fag bearing. Even if the clutch bearing is slightly stripped and otherwise damaged, the sound emitted by the abnormal intonation and irregular measuring device will be distinguished from the sound measurement.Handling Method of Abnormal Phenomena in Fag Clutch Bearing Operation
2 bearing vibration
Fag bearing vibration is very sensitive to bearing damage, such as spalling, indentation, corrosion, crack, wear, etc., which will be reflected in bearing vibration measurement. Therefore, through the use of special bearing vibration measurement (frequency analyzer, etc.), measuring the magnitude of vibration and frequency analysis, it can be inferred through unusual conditions.
The measured values of the position where the sensor is used or installed under bearing conditions are different, so each machine needs to analyze and compare the standard measured values determined in advance.
3. Bearing temperature
The temperature of the bearing, generally the temperature outside the fag bearing room, can be inferred that if the hole can be used to directly measure the temperature of the outer ring of the bearing, it is more appropriate. Usually, the bearing temperature rises for 1-2 hours and slowly reaches a stable state.
The heat capacity of the bearing is the normal temperature of the machine, the heat capacity is large, and the speed and load change. If proper parts are installed during the inspection and troubleshooting of lubricating clutch bearing operation, the bearing temperature will rise suddenly, and the operation will be stopped in case of abnormal high temperature. Take necessary preventive measures.
Check the damage of clutch bearing after demolition, and determine the cause of bearing failure and damage according to the damaged fag bearing.
The crisp sound and sharp squeaking noise may be caused by improper bearing clearance. Insufficient lubrication may also cause metal sound. Dents in the bearing cup track can cause vibration.
As for the noise generated by the equipment caused by knocking scars, this noise has different speed levels. If there is intermittent noise, then the rolling part may be damaged. This sound appears when the surface is damaged on the launch date. If the “hissing” sound pollution often causes serious damage to the clutch bearing and causes irregular huge noise.
However, it is usually unnecessary to replace the clutch bearing at this time. Therefore, damage, of course, can also be perceived through listening. Such as the use of better methods, such as electronic health monitoring equipment, pre eruption operation. method

The second is the raceway sound of rolling mill bearing and its control method. The raceway sound is a smooth and continuous sound made by the rolling body rolling on the raceway surface when the shaft is running. It is a unique basic sound that will occur in all fag bearings.
The general bearing sound is the sound of raceway plus other sounds. The greater the rigidity of the bearing pedestal, the lower the sound pressure level of the raceway sound. If the radial clearance is too small, the sound pressure level and dominant frequency of raceway sound will increase sharply with the decrease of radial clearance.
The methods to control the sound of raceway are: select low-noise bearings, that is, bearings with small waviness, and carefully select the service conditions. Raceway noise often affects the noise of the whole machinery. Reducing raceway noise can reduce the noise of the whole machinery.
Then comes the rolling sound of the imported bearing of the rolling mill and its control method. The rolling sound is the harsh metal friction sound that can occur in all occasions of cylindrical roller bearings.
It mostly occurs in the larger type of grease lubricated bearings, which is more likely to occur in the grease with degraded base oil performance, and almost does not occur in oil lubrication.
In addition, it is easy to occur in winter. When bearing pure radial load, it is easy to occur in the case of large radial clearance, and it is easy to occur in a specific speed range with different models and sizes, both continuously and intermittently.
Special processing methods for the outer ring raceway can prevent the occurrence of rolling sound. If necessary, this kind of bearing can be selected, or the radial clearance of the bearing can be appropriately reduced, the lubricating grease with excellent performance can be used and the rigidity of the parts matched with the bearing can be improved.
