Hydrodynamic Lubrication of Porous Step Thrust Bearings With a Bingham Solid

抄録

Applying the lubrication equation and a modified form of Darcy's low for a Bingham solid to porous step thrust bearings, pressure distributions, core formations, load capacities and friction torques in lubricant film are analyzed, and pressure distributions, flows and stationary regions in porous bearings are evaluated. Interesting result are that the flow region becomes small with a decrease of permeability and an increase of yield stress of a Bingham solid. Experimental result are compared with the analytical ones.
