Abstract:

In this report, a PC-based computer program is described. The computer program calculates the descriptive characteristics of a general elastohydrodynamic ehd lubricated point contact typically found in bearings, gears, and cams. The following characteristics of the contact are calculated 1. The contact maximum and mean Hertzian stress 2. The contact ellipse dimensions 3. The ehd isothermal minimum and central film thickness 4. A thermal film thickness correction factor accounting for the effect of shear heating because of sliding and rolling. In addition, it provides the basic theoretical background and equations used. Keywords Bearings Elastohydrodynamic lubrication Film thickness. JES
