Abstract

La présente invention concerne un palier en élastomère (40) comprenant un premier chemin de roulement (42) ayant un axe de rotation, un second chemin de roulement (44) agencé coaxialement par rapport au premier chemin de roulement (42) et séparé du premier chemin de roulement (42) par un interstice, un corps de palier dans l’interstice reliant le premier chemin de roulement (42) au second chemin de roulement (44), le corps de palier comprenant une pluralité de premières lamines (14) coaxiales par rapport au premier chemin de roulement (42) et une pluralité de secondes lamines (16) coaxiales par rapport au premier chemin de roulement (42), les premières lamines (14) étant formées à partir d’un matériau différent des secondes lamines (16) et un embout d’extrémité en métal (18) relié au premier chemin de roulement (42) ou au second chemin de roulement (44). L’embout d’extrémité en métal (18) comprend un intérieur au moins en partie creux (50). Figure 1
