As for bearings, many people may not be very clear, nor do they know what they are used for. In fact, they are an important part of mechanical equipment and are widely used in industrial machinery. So what parts of the bearing structure are composed of, and what are the differences in the bearing structure, which are detailed below.
1、 Bearing sleeve
1) The inner diameter of the shaft sleeve exceeds the maximum value of the rule, that is, the shaft diameter plus the maximum allowable clearance of the bearing;
2) When the outer diameter of the shaft sleeve is less than the minimum value of the regular size and the knurling method cannot meet the quality requirements of the pipe;
3) When the shaft sleeve is burnt or seized.
2、 Split inlet bearing
1) When the alloy is severely worn and its thickness is reduced by more than 1/2;
2) When the serious area of shelling and cracking of the alloy layer is more than 1/3;
3) The bearing alloy layer is seriously burnt;
4) When the contact angle between the alloy and the bearing shaft is greater than 120o, it is impossible to adjust the contact angle by scraping the surface of the pad mouth or the side clearance is too large to adjust.
3、 Bearing thin wall pad
1) The alloy layer is fused;
2) When the bearing alloy layer is seriously worn and bitten, it cannot be tightened by padding;
3) When the alloy layer is shelled or cracked;
4) When the wear of the alloy layer is not too serious but cannot guarantee the maintenance distance;
5) When the wear of the alloy layer requires the bearing to be tightened by adding a gasket, but the thickness of the gasket exceeds 0.5mm.
