Abstract
In the course of this study, the run-out characteristics of the externally pressurized gas journal bearings will be analyzed theoretically to establish the fundamental concept of precision design of the gas journal bearing, with special attention paid to the relation between the run-out of the rotor and the machining errors of the bearing. For the first step of the study, the modified divergence formulation (DF) scheme to calculate the exact solution of pressure distribution in the bearing clearance is introduced, in which the conventional DF scheme is improved so that it is applicable to the case with point-source of supply holes. As examples of the application of this scheme, the effects of machining errors such as roundness error of the rotor on the bearing characteristics are discussed.
