First of all, we want to emphasize is, keep the bearing lubrication and clean is very important. So when we inspect bearings, you should clean the bearing surface, and then remove the edaimport bearings parts around. We should pay attention to, is very fragile parts oil seal, so in check and disassembling require extra care, not excessive force, so as not to cause damage to parts. Lubrication is very important, not only to the bearings, bearings for all.
But please note, bearing should not be adding too much grease. Inspection method on bearing lubricants for: With little lubricant friction in between two fingers, if the presence of pollutants, can feel it; or in the back of the hand is coated with a thin layer of lubricant, and then sealed optical inspection.
Then is to replace the bearing lubricant.
Then is to replace the bearing lubricant.
edabearing imports oil in addition to the old oil and, if possible, should be poured into the fresh oil and let the machine in low speed rotation for several minutes.
Pollutants as far as possible so that the oil collecting residual, and then poured the oil. Note: oil in use before filtration. While the use of grease lubrication bearing in the replacement of grease, used by Joe remover should avoid contact with cotton to any part of the bearing. While the use of grease lubrication bearing in the replacement of grease, used by Joe remover should avoid contact with cotton to any part of the bearing. Because the residues of these fibers could wedge between scroll and caused damage, especially the application of small bearing more attention should be paid to this problem.
Selection and control 1, shaft and bearing chamber tolerance: press bearing edabearing imports should be flexible rotation not block a sense of. If there is obviously the rotation is not flexible, indicates that the axial size is too large, the tolerance to cut. If the bearing onto the shaft by hand after turning has obvious "rustle" sense, the tolerances of the shaft may be too large or the roundness of the shaft is not good. So in the control of the shaft and housing tolerances to control the roundness, many domestic manufacturers only on tolerance control, no control of roundness.
2, the bearing assembly: because the bearings are precision products, such as improper assembly is easy to bearing raceway damage, cause damage to the bearing. Bearing assembly shall have the special mould, can not be beat, after pressing shaft when only small force, force pressure when only circle circle. The assembly requires use of a pneumatic or hydraulic, upper and lower die on the press mounting to the state level, if tilt will cause the bearing channel due to the stress damage, and the bearing guide ring.
3, to prevent foreign bodies: assembly edaimported bearings easily mounted to the rotor dynamic balance when the dynamic balance of iron filings into bearing interior, so it is best to install bearing dynamic balancing. Some manufacturers in order to convenient assembly, the assembly of some oil or grease lubrication effect in the bearing chamber painted, but the operation is often difficult to control, if the oil or grease in the bearing chamber accumulates more, in the bearing rotates easily along the shaft into the bearing internal. The bearing chamber is best not to oil or grease, such as non coated not to control may not be in the bearing chamber of accumulation.
4, rust prevention paint: paint rust is characterized by multiple sealed type motor, the motor voice in the assembly is very good, but in some time within the warehouse, the electrical noise change greatly, remove the edaimport bearings with serious rust. Many manufacturers are considered to be before the bearing problem, through our advocacy, motor factory is now aware of the main insulation paint problems. This is mainly because the acidic material insulating paint volatile out of the formation of corrosive substances under certain temperature, humidity, the bearing groove corrosion cause bearing damage. The problem can only be good choice of insulating varnish, and after drying ventilation for a period of time after the assembly.
