Abstract

La présente invention concerne un palier lisse à génératrice circulaire (1, 1’) comportant une bague intérieure (2, 2’) et une bague extérieure (3, 3’) aptes à pivoter l’une par rapport à l’autre autour d’un axe de rotation (OZ), ladite bague intérieure (2, 2’) comportant une surface extérieure de contact (4, 4’) et ladite bague extérieure (3, 3) comportant une surface intérieure de contact (5, 5’), ladite surface extérieure de contact (4, 4’) coopérant dans une zone de contact (6, 6’) directement avec ladite surface intérieure de contact (5, 5’). En outre, au moins une génératrice extérieure (7, 7’) de ladite surface extérieure de contact (4, 4’) présente une première forme circulaire définie par un premier rayon (R1) et un premier centre (O1) et au moins une génératrice intérieure (8, 8’) de ladite surface intérieure de contact (5, 5’) présente une deuxième forme circulaire définie par un second rayon (R2) et un second centre (O2), lesdits premier et second rayons (R1 et R2) étant respectivement supérieurs à un rayon moyen de contact (RM) de ladite zone de contact (6, 6’).
