2, the bearing assembly methods
Because bearings are precision products, such as improper assembly is likely to cause damage to the bearing channel, leading to bearing damage. Axial cylindrical roller bearings in the assembly should have a dedicated mold and can not beat, when pressed into the shaft force only a small circle, the circle can only force when pressing circle. Assembly requires the use of pneumatic or hydraulic pressure, when the press-fit to the outer upper and lower mold in a horizontal state, if inclined bearing channel will lead to damage due to power, leaving the bearings guide ring.
3, the assembly to prevent foreign bodies
Bearings mounted to the rotor dynamic balance when it is easy to iron produced when balancing enter IKO bearings inside, so it is best to do before loading the bearing dynamic balancing. Some manufacturers in order to facilitate assembly, the assembly in the bearing chamber coated with some oil or grease lubrication effect, but the operator is often difficult to control the amount, if oil or grease in the bearing interior accumulates more thrust cylindrical roller It can easily enter the inside of the bearing along the shaft when the bearing is rotated. Bearing chamber is preferably not coated with oil or grease, such as non-coated non-bearings shall have to control indoor accumulates.
4, rust preventive paint
Paint rust is characterized by multiple sealed-type motor, the motor assembly, sound good, but put in the warehouse for some time, the motor becomes very abnormal sound, remove the IKO bearings severe rusting. Many manufacturers will be considered to be thrust cylindrical roller bearing problem, through our continuous propaganda, now the motor plant has been realized mainly insulating paint problems. The main problem is because the insulating paint out of the volatile acidic substance at a certain temperature, humidity, corrosive substances are formed, resulting in damage to the bearing channel bearing corrosion. This problem can only be a good choice of insulating paint, and after a period of time after drying ventilation assembly.
