FAG bearing fault character showed critical failures (typically, such as bearing damage, Burns, Sha spallation, raceways, wearing beads) when not more than one week, the equipment, the larger, faster and shorter time intervals. Therefore, the actual bearing fault diagnosis, once a fault is found, its advanced features, to determine a bearing failure should be determined, as soon as possible.
1, selection and control of shaft and housing tolerances: press the bearing into the FAG bearings should be rotational flexibility without blocking. If there is clearly turning the inflexible, it indicates that the axis dimensions are too large, tolerance to go down. If bearings are pressed into the shaft turn by hand after apparent "Salsa", the tolerances of the shaft may be too large or the roundness of the axis bad. So when the control shaft and housing tolerances to control the roundness, many domestic manufacturers currently control the tolerance, not to control the roundness.
2, bearing Assembly methods: since the bearing is a high precision products, such as improper Assembly can easily cause damage to the bearing Raceway, cause damage to the bearings. During Assembly of the bearing should be dedicated mold, able to beat, only small forces when pressed into the shaft, pressure ring only ring stress. Assembly requires a pneumatic or hydraulic, pressure up or down mode to external to the level, such as the tilt causes the FAG bearing Raceway due to mechanical damage and the bearing rings.
3, assemble foreign body to prevent: the bearings are mounted to the rotor dynamic balance easily will enter the bearing dynamic balancing produced when iron filings, and is therefore best done before the load bearing dynamic balancing. Some manufacturers for ease of Assembly, Assembly in the bearing Chamber coated with oil or grease lubrication, but often operations staff is difficult to control, if oil or grease in the bearing Chamber accumulates more, entering the FAG bearings the bearing rotates easily along the axis. Preferably do not oil or grease the bearing room, if not not to control shall not be over bearing Interior accumulates.
4 Prevention of rust, paint: paint the rust is characterized by multiple sealed-type motor, motor Assembly, sounds very good, but after some time in the warehouse, the electrical noise gets so large, remove the bearing with serious rust. Many manufacturers are considered to be before bearing problems, through our advocacy, electrical machinery plant has been realized mainly insulating paint problem right now. The problem mainly because of the acidity of insulating varnishes containing volatile substances formed under certain temperature, humidity, corrosive substances, corrosion and cause damage to the bearings FAG bearing Raceway. The problem can only be chosen well varnished, and after drying after a period of ventilation Assembly.
