静圧気体軸受の軸回転が及ぼす負荷容量への影響

抄録

In recent years, Aerostatic bearings have been considered for use in the medical, semiconductor, and food industries because of their ability to operate cleanly. when a hydrostatic Aerostatic bearing is used to support a large load, the air supply aperture is often arranged in the center of the bearing in a circumferential direction. However, Aerostatic bearings with multiple air supply apertures in the axial direction have been devised to further increase load capacity. However, there are no examples of measured load capacities during shaft rotation. In this study, the load capacity and flow rate were measured by rotating the test shaft with an Aerostatic bearing. The shaft eccentricity ratio ε was set to 0.1 and 0.2. CAE analysis was performed under the same conditions to compare the experimental results and investigate the effect of shaft rotation on load capacity. It was found that the shaft rotation speed had little effect on the load capacity.
