| 摘要 |
The invention relates to mechanical engineering, in particular to plain bearings with liquid or gas lubrication, which are used for radially suspending the rotors of high-speed rotodynamic machines for different use, for example cooling turbines, turbine expanders etc. The inventive blade gasodynamic bearing comprises a body (7), a journal (1), a top collapsible smooth blade (15) and elastically damping sections, each of which consists of a spring element (25) (for example, a corrugated strip) and smooth collapsible blades (27, 30, 33) which are fastened by one end thereof to the bearing body on both sides of the spring element. The increased frictional damping of the bearing at small rotating frequencies is obtained by that, when the journal 1 is radially shifted, a sliding motion with friction takes place between the contacting surfaces of the blades of the elastically damping sections. |
