| description | The utility model relates to a dynamic pressure radial bearing for an elastic support foil piece, which is used for high-speed turbomachinery, and is composed of a bearing body and a foil piece element. The utility model uses the metal foil piece of which back surface is fixed with elastic materials. The bearing overcomes the deficiencies of complicated structure, high manufacturing accuracy requirement, high cost, inhomogeneous surface rigidity, and damping, and poor start-stop performance of the existing dynamic pressure radial bearing, and considerably enhances the running reliability and the economical efficiency of the high-speed turbomachinery. The utility model has the advantages of simple structure, high stability, and good start-stop performance. Moreover, the utility model can be conveniently exchanged with the existing static pressure radial bearing. |
