Hydrodynamic bearing with four lobes (l_1, l_2, l_3, L4) with centres of curvature that are eccentric relative to its geometrical centre, said lobes (L1, L2, L3, L4) being separated by oil feed grooves (5, 6, 7, 8), characterized in that the lobes (L1, l_2, L3, L4) are asymmetrical and include: - angular apertures of at least two different values; - at least two different eccentricities relative to the geometrical centre (O) of the bearing; the centres (01, 03; 02, 04) of two opposing lobes (L1, L3; L2, L4) being aligned with the geometrical centre (O) of the bearing. |
