Turbulent Lubrication Theory Using the Frictional Law : 2nd Report, Its Application to Journal Bearings

抄録

In this paper, an application of the turbulent lubrication theory developed in the first paper to the finite width journal bearings is presented. Bearing performances such as film pressure, load capacity, frictional force and rate of flow in turbulent flows are evaluated by the numerical analysis. The effects of pressure flows on the performances not previously encountered are considered from the analytical results, and are discussed comparing with the published papers. Also, an experiment in a range of high eccentricities and of the mean Reynolds numbers up to 5000 is conducted to compare with the theoretical results. From agreement of the experimental results with the analytical ones, the validity of the theory is confirmed.
