Abstract

Coussinet hydrodynamique à quatre lobes (L1, L2, L3, L4) à centres de courbure excentrés par rapport à son centre géométrique, lesdits lobes (L1, L2, L3, L4) étant séparés par des rainures (5, 6, 7, 8) d'alimentation en huile, caractérisé en ce que les lobes (L1, L2, L3, L4) sont dissymétriques et présentent : des ouvertures angulaires d'au moins deux valeurs différentes; au moins deux excentricités différentes par rapport au centre géométrique (O) du coussinet; les centres (O1, O3; O2, O4) de deux lobes opposés (L1, L3; L2, L4) étant alignés avec le centre géométrique (O) du coussinet.
