The invention discloses a tilting-pad thrust bearing supported through an elastic disc. The tilting-pad thrust bearing is mainly composed of a thrust disc (1), a tilting material layer (2), the elastic disc (3) and a copper ring (4). The copper ring (4) is bonded to the lower surface of the elastic disc (3) and has the functions of supporting the elastic disc (3) and improving the strength of the elastic disc (3). The tilting material layer (2) is bonded to bosses (5) of the elastic disc and used for bearing axial thrust from the thrust disc (1). The tilting-pad thrust bearing has the beneficial effects of being simple in structure, convenient to machine and the like; the integral machining manner is adopted in the elastic disc, and it can be guaranteed that tiles have high planeness; and according to the thrust bearing, the character of deformation coordination of elastic materials is ingeniously utilized, and the thrust bearing has outstanding performance in the aspects of vibration reducing, noise lowering, tile load equalizing, lubricating and the like.
