1, selection and control of shaft and housing tolerances: FAG bearings pressed into the bearing should rotate flexible no block. If there are clearly not flexible rotation, then axis dimensions are too big, the tolerance to cut. Like FAG bearing onto the shaft by hand after turning there is a clear "rustle" sense, the tolerances of the shaft may be too large or the roundness of the shaft well. So in the control room tolerances for shafts and FAG bearings when you want to control the roundness, many domestic manufacturers currently control only tolerance, not to control the roundness.
2, bearing Assembly methods: FAG bearings are high-precision products, such as improper Assembly is easy to cause injury to the FAG bearing Raceway, cause damage to the bearing. FAG bearing Assembly should have dedicated mold, cannot be beat at will, force in pressing axis only small circles, pressing circle only large ring bearing. Assembly call for pneumatic or hydraulic, pressing up or down when touched to be outside on the level of State, such as the tilt causes the FAG bearing Raceway due to mechanical damage and the bearing rings.
3, assembling foreign object prevention: FAG bearing when mounted to the rotor dynamic balance easily produced when iron filings into the FAG bearing internal dynamic balance, so it is best to install FAG bearing dynamic balancing before. Some manufacturers for ease of Assembly, Assembly in interior of FAG bearings coated with some oil or grease lubrication effects, but in many cases the operator is difficult to control, indoor accumulates more if oil or grease FAG bearings, FAG bearings easily along the axis of rotation into the bearing. Bearing room it is best not to paint oil or grease, such as non-coating is not available to control shall not be bearing Interior accumulates.
4 Prevention of rust, paint: paint and rust is characterized by multiple sealed-type motor, motor Assembly, sounds very good, but after some time within the warehouse, the electrical noise change very large, removal of FAG bearings with serious rust. Many manufacturers believe that FAG bearing problems, through our advocacy, motor factory is now aware of the main insulation paint problems. Varnishes used for this issue mainly because of volatile acids under certain temperature, humidity of the formation of corrosive substances, corroded ditch leading FAG FAG bearings bearing damage. The problem can only be good choice of insulating varnish, and assembled in the ventilation after drying after a period of time.
