Beschreibung
Zusammenfassung:	The utility model discloses an elastic supporting device for a foil dynamic pressure bearing, comprising an elastic bearing support composed of an elastic bearing support body and a first key, wherein the first key is arranged at one end of the elastic bearing support body and forms an angle of 70 to 100 degrees with the elastic bearing support body; and a plurality of projections are arranged on the inner and outer surfaces of the elastic bearing support body. The elastic supporting device for the foil dynamic pressure bearing is convenient to manufacture, simple in structure, adjustable in rigidity and high in bearing force, and can be widely applied to the foil dynamic pressure bearing of a high-speed turbomachine.
