In order to determine whether removing FAG bearings can be used to check after bearing wash, carefully check the Raceway surface, rolling, the status of the mating surfaces, cage wear, FAG bearing clearance increases and there is no falling damage, abnormal dimensional accuracy. Non-separation of small ball bearings, inner rings with one hand supporting level, rotate the outer ring to confirm fluency.
When removing the FAG bearings under repair, bearing first record appearance, confirm that the residual amount of lubricant, sampled after checking the lubricant, wash bearings. As a cleaning agent, ordinary gasoline, kerosene.
Removed bearing cleaning, heavy cleaning and light fine wash, respectively in the container, put a metal mesh bottom, FAG bearings do not directly contact the dirt container. Coarse cleaning, if the bearings rotate with dirt, can damage the FAG bearing rolling surface, should be noted. In crude oil cleaning, use a brush to grease removal, adhesive, after largely clean, fine wash.
Sperm washing, is rotate the FAG bearings in cleaning oil side and carefully cleaned. In addition, cleaning oils to keep clean.
Oil bath lubrication is the most common lubrication methods in FAG bearings, suitable for low and medium speed bearing lubrication. Bearings in part submerged in the tank, lubricating oil by the rotation of the bearing parts, then flow back into the sump oil level is slightly lower than the lowest rolling element Centre.
Drip lubrication for rationing lubricants FAG bearing parts are required, one drops 3-8 drops of oil every second, too much oil will cause increased bearing temperature.
Oil transportation to the FAG bearings oil pump filter parts, bearing after the adoption of the lubricating oil filter cooler for later use. Due to the circulating oil can take a certain amount of heat, to cool off the bearing, therefore bearing part of the law applicable to high speed.
With dry compressed air through sprayer mixed with lubricants to form oil mist, spray in FAG bearings, air can effectively cool the bearing and prevent intrusion. This method is suitable for high-speed, high-temperature lubrication of the bearing components.
Pump high pressure oil nozzles shooting to bearing, pierced the oil bearings FAG bearings into the sump at the other end. The bearing during high speed rotation, rolling elements and cage with very high rotation speed of the surrounding air to form air, lubrication methods in general it is difficult to bring oil to the bearings, in which case you must use high-pressure lubricant spray to bearing, position of the nozzle should be placed between the inner ring and the cage Center!
