This invention provides a radial gas hydrodynamic bearing with a boss-type elastic support, comprising a bearing sleeve, an elastic support foil, and a top layer foil. The elastic support foil includes an elastic support foil body and multiple elastic support bosses evenly distributed axially and circumferentially. The elastic support bosses are formed by stamping on the elastic support foil body, with their sidewalls gradually contracting towards the center of the boss to form a trapezoidal platform structure. The top end face of the elastic support boss is a concave arc surface, which fits against the outer circumferential surface of the top layer foil to form a surface contact support. This invention employs a discrete boss elastic support structure, combined with the tilting deformation of the boss sidewalls and the surface contact support method of the concave arc surface, which can effectively improve the operational stability and load-bearing capacity of the radial gas hydrodynamic bearing.
