| Outline of Final Research Achievements |
In this study, in order to improve characteristics of hydrostatic bearings with a low viscosity lubricating fluid such as water, new bearing structures, (i) bearing structure provided with porous land region for achieving high load capacity (ii) a compact and high response flow regulating mechanism for realizing high bearing stiffness, (iii) a novel structure for reducing bearing consumption power, were proposed, and its usefulness was investigated experimentally and numerically. Based on the results of this research, it was consequently found that the consumption power can be reduced by about 20% while improving the load capacity and stiffness of hydrostatic bearings using low viscosity fluid such as water.
