Abstract
Hydrodynamic gas film bearings are widely used for very high speed, lightly loaded rotating machinery such as gas expander, compressor, gyroscope and business machines, etc. In the design of hydrodynamic gas film bearings, it is of cardinal importance to enhance the friction and stability capacities of gas films for keeping the minimum friction loss above a particular level and for minimizing the vibration due to external excitations. Among various types of hydrodynamic gas film thrust bearings, spiral groove and herring bone bearings have an advantage of high stability and load carrying capacity, but the characteristics of the bearings depend on many design parameters. Therefore, when these parameters are designed suitably, it is expected to improve considerably the friction and stability characteristics of the bearings. In this paper, the optimum design methodology is presented to minimize the friction torque and also to maximize the stiffness of gas film for spiral groove and herring bone gas film thrust bearings, and the applicability of the methodology is verified experimentally.
