A study of the characteristic analysis of high speed journal bearings. Optimum design of journal bearings.
Year: 1986
Type: article
Abstract: This paper describes an optimum design of hydrodynamic journal bearings under laminar and turbulent operating conditions. Simplified mathematical expressions are presented for the eccentricity ratio, friction force and whirl onset speed as a function of the Sommerfeld number or eccentricity ratio. The radial clearance, slenderness ratio and viscosity of lubricants which optimize both the oil flow rate and the oil film temperature rise in hydrodynamic journal bearings under the constant load are determined numerically for a wide range of journal speeds.
