摘要:

In this research work, the effects of “O-type” cavitation on the static and dynamic characteristics of turbulent journal bearings submerged in the low viscosity lubricant are investigated theoretically. Extending an idea of “general short bearing theory” proposed by Pan to submerged turbulent journal bearings, “O-type” cavitation pattern, load carrying capacity and altitude angle are determined for a wide range of eccentricity ratio in both laminar and turbulent flow cases. In addition, under the assumption of small displacement of the journal center, the dynamic characteristics such as linearized spring and damping coefficients and whirl onset speed of rotor-bearing systems are obtained. Sample numerical results are indicated in graphic form and the relation between the “O-type” cavitation and the static and dynamic characteristics of submerged turbulent journal bearings is discussed.Presented at the 44th Annual Meeting in Atlanta, Georgia May 1–4, 1989
