Low-noise FAG bearing installation and adjustment can also follow the grouping method of long-life bearings, fits full size the more consistent, the bearing clearance is relatively consistent and hopefully meet the interference if possible, take smaller value to ensure small deformation of bearing Raceway, which move through the noise caused by smaller. In order to decide whether removed the bearings can be used again, to check bearing wash after. Carefully check the Raceway surface, move, the status of the mating surfaces, cage wear, FAG bearing clearance increases and there is no information on dimensional accuracy drop damage, unusual. Non-separation of small ball bearings, the inner ring support level with one hand, rotate the outer ring to confirm fluency.
If the clearance is too large, you can make two rings along the axial deviation: reduces both clearance and increasing axial rigidity, reduces the FAG bearings noise. Clearance of a lot of noise, ideal State is when the maximum temperature of the bearing is in operation when clearance values to zero.
If running makes annoying chirping when Sao Feng cries, you FAG bearing preload is too large, bearing large interference should be slightly relaxed level of pretension. But clearance cannot be too small, so as to avoid temperature over high, and life expectancy. Move in when entering the area without slipping or around a rocky ledge, so that both can also cause increased noise and wear, while small clearance and axial stiffness can eliminate this phenomenon.
Sometimes hosts a large range of working temperature, or dimensions of the shaft and housing bore dispersion is large, cannot be set once, to have a more appropriate clearance, in which case, the FAG bearing outer ring using elastic preload method. Determine the method of clearance is too large: static axial displacement of the bearing, its larger reciprocating, send a big and low noise when in operation.
