TIMKEN self-aligning ball bearings axial clearance adjustment

TIMKEN bearings the axial internal clearance can be achieved through moving the outer ring of axial position.
Adjustment gasket 1 method:
　　In TIMKEN bearing end cover and bearing block end surface Zhijian filled placed a group soft material (soft steel tablets or elastic paper) gasket; adjustment Shi, first does not placed gasket loaded raised heart ball bearing end cover, side uniform to screwed tight bearing end cover Shang of screws, side with hand turning axis, until bearing scroll body and outer ring contact and axis internal no gap weizhi; then measurement bearing end cover and bearing block end surface Zhijian of gap, TIMKEN bearing, again plus bearing in normal work Shi by needs of axis to gap; this is by needed filled placed gasket of total thickness And gasket ready to fill in between the bearing end cover and housing, and finally tighten the screws.
2 adjustment bolt method:
　　Pressure in the TIMKEN bearing rings on the ring, by adjusting bolts pressure; pressure before adjusting, first measure the pitch adjustment bolt, and then slowly tighten the adjustment bolt, until such time as there was no clearance of self-aligning ball bearings, and then calculate the adjustment bolt corresponding rotation angle. 1.5mm,TIMKEN pitch for example needed for the normal functioning of the bearing gap, then the required rotation angle adjustment bolt 3600x0.15/l.5=360; flip 360 adjustment bolt, axial clearance of the bearing on access to 0.5mm, and then snap the gasket to be fixed.
