What are the failure modes and design criteria for non liquid friction sliding bearings?
Boundary film rupture, surface collapse, surface wear. Ensure that the bearings have sufficient fatigue life and limit the permanent plastic deformation of the bearings.
3 checking: v = [v], in order to prevent the high-pressure region PV value is too large and wear. ?Because in the process of starting and stopping the sliding bearing of liquid dynamic lubrication, it is also in the state of non liquid friction and wear. Therefore, it is necessary to carry out the checking of the above three conditions.
Failure form: wear, scuffing.Design guidelines: maintenance of the boundary membrane is not damaged, minimize the wear of bearing materials.Relative condition checking1 checking: PM = [p], to prevent excessive bearing abrasion;2 checking: PMV = [pv], in order to prevent the bearing temperature rise too high and glue and;
