INA Bearings failure of treatment and necessary maintenance measures

Mechanical operation, install the Bearings parts are allowed a certain temperature, when the hand stroked institutions shell should not feel hot as normal, and vice versa that INA Bearings temperature is too high.
Cause of the high Bearings temperature: lubricant quality to meet the requirements or deterioration, lubricant viscosity is too high; institutions assembly tight (gap); Bearings assembly tight; Bearings ring rotation on the shaft or shell; overload ; Bearings cage or rolling body fragmentation.
Bearings to allow a slight running sound at work, if the sound or unusual noise or crash, showed that the Bearings failure.
Rolling noise of the reason is more complex, one of the Bearings 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 Bearings fatigue, the surface of metal falling off, and also make the Bearings radial clearance increases to generate abnormal sound. In addition, INA Bearings lubrication, the formation of dry friction, and Bearings broken and will produce an unusual sound. Bearings wear Songkuang cage loose damage, also have abnormal sound.
1, Bearings maintenance: For as long as possible, Bearings 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. Operation, maintenance matters, INA Bearings rotation of sound, vibration, temperature, lubricant status and so on.
2, Bearings overhaul: Bearings cleaning Bearings maintenance: Demolition, first recorded the appearance of the Bearings, to confirm the amount of lubricant remaining after sampling to check with the lubricant, wash Bearings. As a cleaning agent, ordinary gasoline, kerosene.
Remove the cleaning of the Bearings to the points of rough cleaning and fine cleaning, respectively, on the container, first put the bottom of the metal net, Bearings no direct contact with the dirt of the container. Coarse cleaning, if the Bearings rotation with dirt, will damage the Bearings 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 Bearings side of the rotating cleaning oil, while careful cleaning. In addition, cleaning the oil should be kept clean.
3, Bearings maintenance and judgment: in order to judge removed the Bearings can use to check in the Bearings clean. Check the raceway, the raceway, with the state of the surface wear of the cage, INA Bearings clearance to increase and have nothing to do with dimensional accuracy to drop damage, abnormal. Non-separation of small ball Bearings, with one hand to the inner level of support, rotating outer ring to confirm smooth.
