Abstract
Background: As a successive part, the paper introduces the second mode of abnormal hydrodynamic
thrust slider bearings with divergent surface separations registered in the patents, where the
boundary slippage is artificially designed both on the stationary surface in the inlet zone and on the
whole moving surface.
Objective: To introduce a second method for artificially designing the boundary slippage for the formation
of abnormal hydrodynamic thrust slider bearings.
Methods: The analytical results are presented for the introduced bearings. The performances of the
bearings are demonstrated.
Results: In appropriate operating conditions, the introduced bearings can have considerable loadcarrying
capacities with low friction coefficients on the scales 10-3 or 10-4. With the weakening of the
boundary slippage on the moving surface, the load-carrying capacities of the bearings are all increased,
while the friction coefficients of the bearings are all reduced.
Conclusion: When the boundary slippage is present both on the stationary surface in the bearing inlet
zone and on the whole moving surface, abnormal hydrodynamic thrust slider bearings can be designed
with the surface separation in the bearing inlet zone lower than that in the bearing outlet zone. The performances
of these bearings are quite satisfactory.
