If the calculation results of contradiction is too large (usually have this situation only at the highest speed), only take double lubricating measures under ring lubrication method and static pressure lubrication method,which is likely to make the DMN value exceeded 3 million of the bearing.
Considering the high speed bearing clearance not only include the factors mentioned above, but also the effect of thermal elongation axis on the clearance of the bearing. The requirements in the working state, which has the best clearance at operating temperature.
This clearance formed under the condition of the inner ring and the outer ring of the ball groove center aligned accurately. As thehigh precision bearings to reduce the relative sliding and internal friction, clearance of SKF 71900C/DB angular contact ball bearing had better not use relative displacement methods within the inner ring and the outer ring along the axial direction to adjust the ball bearing.
