Abstract

The invention concerns an aerodynamic plain bearing for shafts (1) rotating at high rotation 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). In order to make do with as few components as possible and as little radial installation space as possible, provision is made for segments (2" or 2a) of the structure to be thin-walled, elastic sleeve sections with a uniform or profiled wall thickness and a low coefficient of friction, which are simultaneously damping and spring elements.
