    摘要： The invention provides a tilting-pad thrust bearing that requires less oil supply and a rotary machine having the same. A tilting-pad thrust bearing 100 comprises: multiple oil inlets 10 disposed in spaces between pads 6; multiple outflow guide grooves 12 each formed near the inner circumferential edge of the sliding surface of the pad 6 such that the outflow guide grooves 12 extend in a circumferential direction; and multiple inflow guide grooves 13 provided separately from the outflow guide grooves 12 and formed at the leading ends of the sliding surfaces of the pads 6 so as to be located more radially inward than the oil inlets 10. Each outflow guide groove 12 is open to the sliding surface and the trailing end surface of the pad 6. Each inflow guide grooves 13 is open to the leading end surface and the sliding surface of the pad 6.

    摘要： A tilt pad bearing may include a support structure having first and second support structure surfaces. A pivot may have first and second pivot surfaces, and the first pivot surface may be coupled to the second support structure surface. A pad may have first and second pad surfaces, and the first pad surface may be coupled to the second pivot surface. A path of fluid communication may extend from the first support structure surface, through the pivot, and to an opening in the second pad surface.
