What is standard of sliding bearing to waste?
A, collar
A maximum of 1) collar diameter in excess of the prescribed, the diameter of axle and bearing the maximum allowable clearance;
2) collar diameter less than the minimum value of specified size, and adopt the method of knurling cannot guarantee the quality requirements;
3) loss or holding shaft sleeve arises.
Second, to open the bearing
1) bearing alloy serious wear and tear, more than 1/2 its thickness thinning;
2) bearing alloy layer shell, crack is serious, an area of more than a third;
3) bearing alloy layer of serious loss;
4) bearing alloy contact with shaft Angle is greater than 120 o, unable to use the method of chipped WaKou plane to adjust the contact Angle and side clearance is too large to adjust.
Third, thin wall tile
1) burning-out bearing alloy layer;
2) heavily damaged bearing alloy layer, bite, failing to tighten with padded method;
3) bearing alloy layer shell or crack;
4) bearing alloy layer is not too serious wear and tear, but does not guarantee maintenance interval;
5) bearing alloy layer of wear and tear, need padded method is used to tighten the bearing, but when the gasket thickness more than 0.5 mm.
Fourth, thrust bearing
1) thrust segment serious wear and tear, more than 1/2 its thickness thinning;
2) burning fuse thrust segment;
3) thrust segment shells, cracks.
