In the functioning of the institutions, install the bearing parts are allowed a certain temperature, when the hand stroked institutions shell should not feel hot as normal, and vice versa that the FAG bearing temperature is too high.

Cause of the high bearing temperature: lubricant quality to meet the requirements or deterioration, lubricant viscosity is too high; institutions assembly is too tight (gap); plane bearing assembly tight; bearing ring rotation on the shaft or shell; The load is too large; bearing cage or rolling body fragmentation.

Plane bearings allow a slight running sound at work, if the sound or unusual noise or crash, showed that the bearing failure.

Rolling noise of the reason is more complex, one of the bearing inner and outer rings with surface wear. As a result of this wear and tear, destruction of the bearings and housings, bearings and axes with the relationship, leading to the axis deviated from the correct location, abnormal sound in the high-speed movement of the shaft. When the bearing fatigue, the surface of metal falling off, and also make the bearing radial clearance increases to generate abnormal sound. In addition, FAG bearing lubrication, the formation of dry friction, and bearing broken and will produce an unusual sound. Bearing wear Songkuang cage loose damage, also have abnormal sound.

1, bearing maintenance: For as long as possible, bearing the original performance to be maintained in good condition maintenance, overhaul, with a view to accident prevention in the first place, to ensure reliability of operation, improve productivity, economy.

Maintenance best corresponding mechanical operating conditions, operating standards, on a regular basis. The surveillance operation, to supplement or replace the lubricant, the inspection of the regular demolition. Maintenance issues in the operation, FAG bearings rotating sound, vibration, temperature, lubricant status and so on.

Overhaul of bearings: bearing cleaning bearing overhaul: demolition, the first record of the plane bearing the appearance of, to confirm the amount of lubricant remaining, sampling check lubricant, wash bearings. As a cleaning agent, ordinary gasoline, kerosene.

Remove the cleaning of the bearing to the points of rough cleaning and fine cleaning, respectively, on the container, first put the bottom of the metal net, bearing no direct contact with the dirt of the container. Coarse cleaning, if the bearing rotation with dirt, will damage the bearing rolling surface, it should be noted. Coarse cleaning oil, use a brush to remove to grease, adhesive material, and generally clean, and transferred to the sperm washing.

Sperm washing is the bearing side of the rotating cleaning oil, while careful cleaning. In addition, cleaning the oil should be kept clean.

3, bearing maintenance and judgment: in order to judge removed the bearings can use to check in the bearing clean. Check the raceway, the raceway, with the surface state, cage wear, FAG bearing clearance to increase and there is nothing to do with dimensional accuracy decreased damage, abnormal. Non-separation of small ball bearings, with one hand to the inner level of support, rotating outer ring to confirm smooth.
