Abstract
This paper describes experimental analysis of six kinds of noncircular journal bearings which have circular base and elliptical base geometries. The measurements are carried out for various values, such as vibration amplitude of journal. frequency of journal, and temperature rise of oil film, of bearing orientation angle for each noncircular journal bearing. It was found that the stabilities of noncircular journal bearings are improved remarkably by suitable selection of optimal bearing orientation angles.
