Hydrodynamic air film thrust bearings are widely used for very high speed, lightly loaded rotating in many machinery because of their low friction, noiseless operation, simple structure etc. In the thrust air beading, grooved bearing have an advantage of high stability and load caring capacity, and then, the characteristics of the bearing is strongly influenced by bearing geometry, such as groove shape, groove depth, groove width, number of grooves, seal radius. Therefore, it is important to optimize geometry, however as for as the authors know, there is no literature treated above optimization. This paper describes the optimization of bearing geometry of thrust air bearing for improving various bearing characteristics theoretically.
