KOYO bearing properly installed and lower noise

1, low noise, installation and adjustment of KOYO bearing can also follow the long life bearings grouping method, makes the interference fit the size is consistent, KOYO bearing clearance is relatively consistent, and hope to cooperate with interference within may take smaller values, to ensure the deformation of KOYO bearing raceway is small, and rolling body caused by noise is smaller. 2, clearance on the relationship between the noise is very large, ideally when KOYO bearing is in running state, the highest temperature clearance value is zero. Judgment methods of clearance is too large, stationary state make bearing axial displacement, the extent of the reciprocating is bigger, the big and heavy turbidity of a noise during operation. 3, if the hate sharp whistlers, shows KOYO bearing preload is too big, preloaded, bearing a large prestressing degree should have to relax. If the clearance is too large, can make the two bearing ring along the axial relative offset slightly: both reduced clearance, and increase the axial rigidity, KOYO bearing noise can be reduced. 4, rolling body around would not bite into the no-load area or channeling, that will not only increase the noise can also cause wear and tear, and the small clearance and large axial stiffness can eliminate the phenomenon. But cannot too small clearance, lest cause high temperature and shorten the life. 5, sometimes because of the host operating temperature range is very large, or the size of the shaft and the bearing hole discreteness is very big, can't get a setting on a proper clearance, in this case, to KOYO bearing's outer ring by using elastic constant pressure preload.
