Abstract
The invention concerns an aerodynamic plain bearing for shafts (1) rotating at high speeds, with a bearing housing (4) having a cylindrical bore (3) and with a tangentially attached, elastic and damping structure (2) having segments (2' or 2a), which is supported at a plurality of circumferential points (2') in bearing housing (4) and forms a multiple converging running gap (6) with shaft (1) and damping gap (5) with bearing housing (4). A minimum number of components are used and radial installation space is also minimized. Segments (2' or 2a) of the structure are thin-walled, elastic sleeve sections with a uniform or profiled wall thickness and a low coefficient of friction, as from titanium nitrite, and simultaneously act as damping and spring elements.
