Performance Characteristics of Journal Bearings with Vertical Shaft

In this study, a detailed theoretical analysis of journal bearing with a vertical shaft is presented. It is based on a finite difference approach applied to Reynolds' equation, obtaining the static and dynamic pressure distribution produced by a small journal perturbation. Integration of the steady state pressure distribution yields the load ...
