Abstract

A static pressure thrust bearing includes a shoe member or a thrust axis provided with a static pressure pocket and a land for sealing the static pressure within the pocket, and a swash plate on a sliding surface provided with a slide surface upon which the shoe member is slidable. Lubricating oil flows through the shoe member and between the slide surface and the land surface, and each of the land and slide surfaces has a plurality of very small recesses so as to receive small particulates which may be within the lubricating oil. The difference of the static pressure occurring between the land surface and the slide surface alternately moves the small particulates originally disposed within one of the recesses thereof, into the other recesses as a result of the sliding movement of the shoe member whereby the small particulates are removed from the bearing by means of the lubricating oil.
