79AbstractImportance of journal bearings is not hidden to anyone with respect to many uses of themin industry Elliptical bearings are one type of non circular journal bearings This type ofbearing is more advantageous than circular journal bearing in terms of lower rise oftemperature of oil inside it and their better performance versus vibration In this study energy equation has been adiabatically solved by coupling with Reynolds equation Thecurrent essay intends to examine effect of geometric parameters of elliptical bearings onbearing functional parameters by which the optimal design of elliptical bearing can befound and at the same time the conducted works in effect of geometric parameters maybe completed on functional parameters The given results indicate that as parameter G non circular parameter is added in bearing and difference is increased among size ofmajor axis transverse diameter and minor axis conjugate diameter the maximumdiameter of fluid film and maximum rise of pressure are increase and maximum oiltemperature potential for tolerance of load and friction force are decreased Following toincrease in parameter of eccentricity i e approaching of shaft of bearing themaximum pressure is added and maximum oil temperature and potential for tolerance ofload as well as frictional force are also increased Keywords Elliptical bearings Performance Parameters Geometric parameters Adiabatic solution of the energy equation
