Clearance of some rolling bearings can be adjusted, like Angular contact ball bearing, tapered roller bearing and thrust ball bearings and thrust rollers bearings.
There are many method to adjust clearance. Such as Gasket adjustment method, Nut adjustment method, Screw cover adjustment method and Inner jacket adjustment method.
Following case is the clearance adjustment experience for tapered roller bearing
1.Put the transmission shaft flat,make bearing inner and outer rings perpendicular to the it.
2.Turning shaft and observing roller movements status, rolling or sliding. It means axial clearance is too large if there are 4 or 5 balls sliding during status. It means clearance is too small if all the rollers are rolling. Ideal status is 2 or 3 rollers are sliding.
3.During adjustment clearance process. Besides meet to the normal rolling bearing assemble technical and demands, the impact of temperature rise and lubricating should be also considered. Detailed inspection and secondary adjustment are required after the operation experiment
