- 論文の詳細を見る
This paper describes an optimum design of hydrodynamic journal bearings under laminar and turbulent operating conditions. Simplified closed-form design formulas are presented for the eccentricity ratio, friction force on the journal surface and whirl onset velocity as a function of the Sommerfeld number or eccentricity ratio. The radial clearance, slenderness ratio and viscosity of oil, which optimize both the oil flow rate and the oil film temperature rise in hydrodynamic journal bearings under a constant load, are determined numerically for a wide range of journal revolution speeds.
