抄録

In externally pressurized gas-lubricated circular thrust bearings, the occurrence of depression in the pressure profile is observed under some working conditions. Succeeding the previous paper on the theoretical investigation of the pressure depression, the pressure distribution in externally pressurized circular thrust gas bearings with a circular recess is investigated theoretically by assuming the generation of a normal shock wave in the bearing recess. Good quantitative agreement is found between the analytical results and available experimental data except the case of small bearing clearance height or deep recess. In order to prevent the pressure depression just after the gas supply hole, it is effective to make a round or tapered chamfer at the entrance edge of the hole to the bearing clearance or to make the recess tapered doubly. By these alternations, the shape of pressure distribution becomes flatter so that the load capacity can increase remarkably.
