How to adjust the axial clearance of imported bearings method



Bearing axial clearance adjustment method, currently consists By Kerry bearings (Tianjin) Co., Ltd. with you a detailed introduction. Bearing axial clearance inside the outer ring can be moved by means of the axial position to achieve. Adjust the main common internal axial clearance of imported bearings There are two methods, namely the method of adjusting shim and adjustment bolt method.

An adjusting washer law:

In lysn-bearing imported bearing end cover and fill the place between a group of soft material (soft steel or flexible paper) pads;

Adjustment, first put on hold the bearing cover gasket, side evenly tighten the screws on the Slewing bearing cap, side rotary shaft by hand until the outer ring of the bearing rolling contact with the inner shaft so far there is no gap;

Then measure the bearing cover and the gap between the end bearing, the bearing together with the normal operation of the axial gap needed;

This is required to fill up the total thickness of the gasket, and then fill in the prepared gasket bearing between the end cap and the bearing seat, and finally tighten the screws.

2 adjusting bolts law: the pressure in the pressure ring on the outer ring of bearings, adjusting bolt pressure; adjust the pressure before the first pitch of the adjustment bolt to be measured, and then slowly tighten the adjusting bolt until the bearing no internal clearance date, and then calculate the corresponding rotation angle adjustment bolt. For example pitch of 1.5mm, the normal operation of the bearing clearance needed, then adjust the angle of rotation of the bolt required 3600 × 0.15/l.5 = 360; Then turn the adjusting bolt reverse 360, miniature bearings to get 0.5mm axial gap, and then the stopper washer can be fixed.
