A Comparison study on the Performance of Several Types of Air Lubricated Hydrodynamic Thrust Bearings

여러 가지 형식의 동압 공기 윤활 스러스트 베어링의 성능에 대한 비교 연구

In this paper, numerical analyses were undertaken to calculate the static and dynamic performances of step-pocket, inward pumping spiral grooved, outward pumping spiral grooved and herringbone grooved bearings. For each bearing, optimal values for various design parameters were obtained to maximize the load capacity and the stiffness and bearing performances were calculated. The optimized performances of these bearings were compared to conclude that the performance of step-pocket bearing is better than the other bearings.
