多孔質スラスト軸受の潤滑機構に関する実験的研究 : スラスト受面の最適化と潤滑状態に関する実験的考察

抄録

The application of hydrodynamic fluid lubrication theory is attempted to the thrust bearings with wave shaped axial end surfaces. The optimization of the wave height (especially three dimensional wave height) and of the surface porosity are experimentally determined concerning lubrication characteristics of the friction coefficient. The measurements of lubrication characteristics such as, a friction coefficient, the temperature rise, floating height and oil consumption rate for estimation of life expectancy etc. are evaluated. In this research, the results of this application on thrust bearings clearly showed considerable improvement over the conventional thrust bearings. Furthermore, this experimental research is clarified the lubrication conditions of respective thrust loaded axial end surfaces.
