Abstract

Couronne d'orientation à roulement comprenant, entre ses deux bagues 1 et 2 réalisées chacune d'une seule pièce, une rangée de rouleaux 6 formant une butée et une rangee de billes 7 formant un roulement à contact oblique. La couronne est à même de supporter des efforts axiaux, des efforts radiaux et des moments de déversement sans déformation des portées. Applications : grues, engins de travaux publics, gros engins de manutention.
