Abstract:

The fundamental Greens Function for journal bearings are applied to both externally pressurized bearings and self-acting bearings. The Greens Function solution agrees very well with the theoretical solution of a self-acting bearing with Sommerfeld conditions. Small discrepancies between the Greens Function solution and experimental hydrostatic bearing data exist at the higher eccentricities. Differences arise from errors in estimating orifice discharge coefficients, neglect of local turbulent conditions in the Greens Function solution and tolerances in the real clearances of experimental models. All three of these factors seem equally important in an error analysis, hence the accuracy of Greens Function solutions is compatible with the realities one must recognize in applying the theory of lubrication.
