Thrust bearing with new pad designs

Hydrodynamic thrust bearing with new pad designs (employing bionic texture) has been developed. The effects of texture parameters such as pocket/texture depth, extend of pocket and fish texture spread in the circumferential and radial directions, the number of scale texture waves in circumferential and radial directions on pads have significant impact in improving the performance of the thrust bearing. The micro-rectangular pocketed fish scale texture yielded substantial increase in minimum film thickness and reduction in friction coefficient as compared to the other pad designs.
