Abstract

Ce roulement 10 comprend une bague intérieure 11 avec des chemins de roulement 12 et une bague extérieure 13 avec un chemin de roulement 14. Une série de rouleaux 15 sont montés dans l'espace annulaire 16 formé entre les chemins de roulement intérieur et extérieur. Les rouleaux sont profilés de manière à créer sous charge un moment résiduel de frottement qui tend à régler le sens d'inclinaison des rouleaux. Le profil des rouleaux est à rayon de courbure variable tandis que les chemins de roulement ont un rayon de courbure constant. La répartition du moment de frottement sur les rouleaux produit une inclinaison positive qui diminue l'échauffement et les forces de frottement et augmente donc la durée de vie utile du roulement. Applications notamment aux roulements à rotule sur deux rangées de rouleaux.
