How to ensure the bearing in after installation does not produce big deformation

1, install the shaft and housing bore roundness and verticality of the shoulder block in accordance with the corresponding precision of the bearing requirements;
2, not only to the accurate calculation of rotating ring with the amount of interference, but also to accurately calculate the appropriate co-ordination of the fixed ring;
The rotating ring blanch the amount of interference to the extent possible, should be made ??smaller. Ensure the impact of thermal expansion of the operating temperature, and the maximum speed the centrifugal force of impact, it would not then cause a tight fit to the surface of the creeping or sliding. Fixed ferrule select a minimal gap with the work load size and bearing size or interference fit, too loose or too tight is not conducive to maintaining the original precise shape.
High, bearing in operation under high speed conditions, operating temperature, special attention should be rotating ring with not too loose to prevent the emergence of the eccentric, and a fixed ring with the non-emergence of the gap, to prevent the ring under load deformation and excitation vibration.
Take small interference with the conditions on a fixed circle is matched to the surface of both sides have a high shape accuracy and smaller roughness, or cause installation difficulties removing it more difficult, in addition, also need to consider the impact of the spindle thermal elongation.
To use pairs of duplex angular contact ball bearing spindle. Because it is mostly lighter load, with the amount of interference such as large, internal axial preload will be significantly larger, it will adversely affect. Spindle double row cylindrical roller bearings and tapered roller bearing spindle, the load is relatively large, so with the earnings are also relatively large.
Only when the bearing is installed to do the five points above in order to ensure the bearing installation will not generate excessive deformation.
