SKF bearing the special gap adjustment methods, the main point is that the needle roller bearings in the process of the installation or use of, if not normal not meet the requirements of the time, it should be how to adjust it?
Needle bearing clearance adjustment is more difficult compared to other bearing types. Tell us something about worst Lane needle bearing, for example, general needle roller bearings are used in bigger dedicated machine.
Needle roller bearings inside the axial gap to move with the axial position of the outer ring. The adjustment of the following two methods can be used for reference use needle bearing axial clearance.
A spacer method:
Needle bearing in the bearing cap, and put a face to fill between the soft material (soft or flexible steel paper), gaskets, adjust, first held, on the one hand, install the needle bearing cover gasket, tighten evenly roll pin bearing end cap screws, square shaft hand until the needle bearing contact with the outer shaft, until the house is no gap, then the gap between the cover and measurement of needle roller bearings needle roller bearings surface, needle roller bearings during normal working hours plus the needs of the axial gap, which is needed to fill the total thickness of the gasket, and then prepared to fill the cover gaskets, needle bearing surface between the needle roller bearings, and finally tightening the screws.
2 adjustment bolts:
Rotation in the needle bearing outer ring on the pressure, the pressure regulator to the first ball in the bolts before the adjustment to measure the adjustment bolt, and then slowly tighten the adjustment screw corresponding to the needle bearing gap until the internal pressure until then calculate the adjustment bolt angle.
