Effect of slot parameters on load capacity of axial type slot restrictor Water Lubricated Bearings

Abstract

In this study, the effect of parameters such as the clearance between the bearing inner diameter and the shaft diameter, and the clearance of the water supply slot on the load capacity was investigated using both experimental and CAE analysis approaches with a small-diameter hydrostatic water lubricated bearing. It was found that a specific slot clearance maximizes the load capacity for a certain radial clearance, the flow rate increases as the slot clearance increases, the load capacity is proportional to the eccentricity ratio and pressure, and the flow rate is proportional to the pressure.
