ABSTRACT:
The bearing pads of a hydrodynamic tilting pad thrust bearing are cut from a ring and arranged in a circle within a retainer for bearing the load of a collar fastened to a rotating shaft. The leading and trailing edges of respective adjacent pads contain open edge grooves which together form a pocket for receiving and dispensing lubricating and cooling oil under controlled conditions. Semicircular grooves in the edges of the adjacent pads together form generally circular ducts through which the oil is conducted to the pockets.
