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.
'invention a trait à un palier lisse aérodynamique pour des arbres (1) tournant à haute vitesse, avec un carter de palier (4) ayant un alésage cylindrique (3) et avec une structure élastique et amortissante (2) attachée tangentiellement et dotée de segments (2" ou 2a) qui est appuyée en plusieurs points circonférentiels (2') du carter de palier (4) et forme un joint mobile multiconvergent (6) avec l'arbre (1) et un joint d'amortissement (5) avec le carter de palier (4). Pour s'en tenir àun minimum de composants et d'espace radial d'installation, il est prévu que les segments (2" ou 2a) de la structure soient des sections de manchon élastique à paroi mince avec une épaisseur de paroi uniforme ou profilée et un faible coefficient de frottement, qui servent à la fois d'éléments d'amortissement et d'élasticité.
