ABSTRACT:
A supercharger thrust bearing for use in a machine rotatable at a high speed includes radial oil grooves formed in a pad surface. Gradients are formed at the outward radial ends of the oil supply grooves such that the groove depth sequentially diminishes as the outside in the radial direction is approached. The machine rotatable at a high speed is, for example, a boat or a ship. The lubricating oil inside the oil supply grooves is forced out by the gradients and creates a dam. The lubrication oil flowing in a circumferential direction on the pad surface, which is heated on the pad surface, is stopped by this dam and turned to a radially outward direction. The heated oil is pushed out from the pad surface and the new cold oil is caused to flow onto the pad surface from the radial grooves.
