During the operation of the mechanism, the part where the bearing is installed is allowed to Fag Plane Bearing have a certain temperature. When touching the mechanism shell by hand, it is normal to feel that it is not hot. Otherwise, it indicates that the temperature of fag bearing is too high.
The reasons for high bearing temperature include: the quality of lubricating oil does not meet the requirements or deteriorates, and the viscosity of lubricating oil is too high;
The mechanism assembly is too tight (insufficient clearance); The Fag Plane Bearing plane bearing assembly is too tight; The bearing race rotates on the shaft or in the shell; Excessive load; Broken bearing cage or rolling element, etc.
The plane bearing is allowed to have a slight running sound during operation. If the sound is too loud or there is abnormal noise or impact sound, it indicates that the bearing is faulty.
The causes of rolling bearing noise are complex. One is the wear of the mating surfaces of the inner and outer rings of the bearing. Due to this wear, the matching relationship between the bearing and the shell and between the bearing and the shaft is damaged,
resulting in the axis deviation from the correct position and abnormal noise when the shaft moves at high speed. When the bearing is tired, the metal on its surface will peel off, Fag Plane Bearing which will also increase the radial clearance of the bearing and produce abnormal noise.
In addition, insufficient lubrication of fag bearings, dry friction and broken bearings will produce Fag Plane Bearing abnormal sound. After the bearing is worn and loose, the cage is loose and damaged, which will also produce abnormal noise.
it must be maintained and overhauled in order to prevent Fag Plane Bearing accidents, ensure the reliability of operation and improve productivity and economy.
Maintain the operation standard of corresponding mechanical operation conditions and carry out it regularly. The contents include monitoring the operation status,
replenishing or changing the Fag Plane Bearing lubricant, and regular disassembly inspection. Maintenance items during operation include rotating sound, vibration, temperature, lubricant state of fag bearing, etc.
2. Bearing maintenance: bearing cleaning: when removing the lower bearing for maintenance, first record the appearance of the plane bearing, confirm the residual amount of lubricant, and then wash the bearing after sampling the lubricant for inspection. As a cleaning agent, gasoline and kerosene are commonly used.
The cleaning of the removed Fag Plane Bearing bearing is divided into coarse cleaning and fine cleaning. They are placed in the container respectively. First, put the metal mesh bottom so that the bearing does not directly contact the dirt of the container.
During rough cleaning, if the bearing rotates with dirt, it will damage the rolling surface of the bearing, which should be paid attention to. In the coarse cleaning oil, use a brush to remove the grease and adhesion. After it is roughly clean, turn to fine cleaning.
Fine cleaning is to carefully clean the bearing while rotating in the cleaning oil. In addition, the Fag Plane Bearing cleaning oil should always be kept clean.
3. Maintenance and judgment of bearing: in order to judge whether the disassembled bearing can be used, it should be checked after the bearing is cleaned. Check the state of raceway surface, rolling surface and mating surface, the wear of cage,
the increase of fag bearing clearance and the damage of irrelevant dimensional accuracy. For non separable small ball bearings, support the inner ring horizontally with one hand and rotate the outer ring to confirm whether it is smooth.
