摘要：A thrust bearing comprises at least one diamond bearing segment, wherein the segment has a front surface and a back surface. A plurality of bearing pads extend a predetermined distance from the front surface, each of the plurality of bearing pads has a load surface substantially parallel to the front surface. The plurality of bearing pads act cooperatively to provide a load bearing surface area. The bearing pads are shaped and arranged in a predetermined pattern to enhance the load carrying surface area, and the predetermined pattern creates a plurality of flow micro-channels between the bearing pads. In another aspect, a thrust bearing comprises a diamond bearing surface, and a predetermined pattern of cavities formed in the diamond bearing surface for providing a fluid reservoir for lubricating and cooling the load surface.
