Title (EN) ASSEMBLY OF A SHAFT AND AN ELEMENT INTENDED TO FORM A ROTOR AND MANUFACTURING METHOD
(FR) ENSEMBLE D'UN ARBRE ET D'UN ELEMENT DESTINE A FORMER UN ROTOR ET PROCEDE DE FABRICATION
Abstract:
(EN) The invention concerns an assembly comprising a shaft (12) and an element (16) configured to be coupled on the shaft (12) by shrink-fitting, the shaft (12) comprising an inner cavity (20) in an axial shrink-fitting portion (P12), an internal diameter (Di20) of the inner cavity (20) being greater than or equal to 50% of an external diameter of the axial shrink-fitting portion (P12) and a difference (H) between the external diameter of the axial shrink-fitting portion (P12) and an internal diameter of the axial shrink-fitting portion (P16) of the element (16) being less than or equal to 50 μm when the element (16) is not coupled to the shaft (12), the external diameter of the axial shrink-fitting portion (P12) of the shaft (12) being greater than the internal diameter of the axial shrink-fitting portion (P16) of the element (16). The invention also concerns a method for manufacturing such an assembly.
(FR) L'invention concerne un ensemble comprenant un arbre (12) et un élément (16) configuré pour être couplé sur l'arbre (12) par frettage, l'arbre (12) comprenant une cavité interne (20) dans une portion axiale de frettage (P12), un diamètre intérieur (Di20) de la cavité interne (20) étant supérieur ou égal à 50% d'un diamètre extérieur de la portion axiale de frettage (P12) et une différence (H) entre le diamètre extérieur de la portion axiale de frettage (P12) et un diamètre intérieur de la portion axiale de frettage (P16) de l'élément (16) étant inférieure ou égale à 50 pm lorsque l'élément (16) n'est pas couplé sur l'arbre (12), le diamètre extérieur de la portion axiale de frettage (P12) de l'arbre (12) étant supérieur au diamètre intérieur de la portion axiale de frettage (P16) de l'élément (16). L'invention concerne également un procédé de fabrication d'un tel ensemble.
