Abstract: A tilting pad thrust bearing and a tilting pad thrust bearing assembly are provided. The tilting pad thrust bearing is configured such that when a load is concentrated on only a portion of a thrust bearing because of eccentricity or inclination of a rotating shaft, associated tilting pads are tilted so that the load can be dispersed to the other tilting pads to which comparatively small load is applied, whereby the tilting pads to which the concentrated load is applied can be prevented from being damaged. Furthermore, the tilting pads can be fixed by oil supply nozzles without using a separate fastening member, whereby the size of the tilting pad thrust bearing can be markedly reduced. The tilting pads and a plate have improved structures so that the time and cost required to manufacture the tilting pad thrust bearing or tilting pad thrust bearing assembly can be reduced.
