A slider bearing consists of a sleeve surrounding a cylindrical shaft that is free to move axially within the sleeve. A lubricant (e.g., grease) is in the gap between the sleeve and the shaft to isolate the metal surfaces and support the stress resulting from the shaft motion. The diameter of the shaft is 1 in., and the sleeve has an inside diameter of 1.02 in. and a length of 2 in. 

The application of the Reynolds equation to a simple problem in lubrication is illustrated by an examination of the plane slider bearing, which is basically a combination of two plane surfaces, one of which is inclined relative to the other. Figure 2-4 is a diagrammatic cross-...

In the plane slider bearing the shear stress on the surface y = h is on the surface y = 0, (Tj ). These conditions, together with the convention used for the direction of the velocity give the expression below for the frictional force in the oil film between two surfaces ...

To obtain an estimate of the deformation parameter we choose a few typical values from slider bearing appllctlons. Based on these estimates we select a range of study for the deformation parameter. Our aim Is to find the behavior of this elastohydrodynamlc system for a practical parameter range. We select...
