1 installation and adjustment of FAG bearings, low noise can also follow the approach of grouping of long-life bearings, making interference size is combined with more consistent, FAG bearing clearance were more consistent, and wish to complement this interference takes smaller value where possible, to ensure that FAG bearing raceways and small deformation, scrolling through the noise caused by small.
2, the relationship between clearance on the noise is large, ideal State is when the maximum temperature of FAG bearings in operation State, exactly zero clearance values. Judgment of excessive clearance method: static axial displacement of the bearing, its greater range of reciprocating, make a large and low noise when in operation.
3, if you hate loud shrill cries issued when running, you FAG bearing preload is too large, bearing a large pre-interference should be slightly relaxed level of pretension. If the clearance is too large, you can make two along the axial bearing rings relative deviation: reduces both clearance and increases axial rigidity, reduces the FAG bearing noise.
4, scroll bars will be slipping in into a loading zone or Hunt around, this would increase the noise can also cause wear, small clearance and greater axial stiffness can eliminate this phenomenon. But clearance cannot be too small, so as to avoid overheating and shortened life expectancy.
5, sometimes due to host a large range of working temperature, or discrete nature of shaft and housing bore size is very large, cannot be a set would be a more appropriate clearance, in this case, elastic constant pressure could be on the outer ring of FAG bearings preload method.
