Abstract Rotor stage of an axial turbine for the gas or steam expansion comprising a shaft (1), adapted to rotate around a main axis (A), and a plurality of vanes (2), the shaft (1) having an annular recess (7) extending around the main axis (A), said shaft (1) further comprising an introduction slot (8) extending laterally from the annular recess (7), the annular recess being adapted to engage the roots (3) of the vanes (2) and the introduction slot (8) being adapted to allow the insertion of the roots (3) of the vanes (2) into the annular recess (7), said rotor stage further comprising a coak (11) adapted to be inserted into the introduction slot (8) through an exclusively radial movement, to constrain the roots (3) of the vanes in an operative position inside the annular recess (7). L'invention porte sur un étage de rotor d'une turbine axiale pour la détente de gaz ou de vapeur, lequel étage comprend un arbre (1), apte à tourner autour d'un axe principal (A), et une pluralité d'aubes (2), l'arbre (1) ayant un creux annulaire (7) s'étendant autour de l'axe principal (A), ledit arbre (1) comprenant de plus une fente d'introduction (8) s'étendant latéralement à partir du creux annulaire (7), le creux annulaire étant apte à venir en prise avec les racines (3) des aubes (2), et la fente d'introduction (8) étant apte à permettre l'insertion des racines (3) des aubes (2) dans le creux annulaire (7), ledit étage de rotor comprenant de plus une clavette (11) apte à être insérée dans la fente d'introduction (8) à l'aide d'un mouvement exclusivement radial, de façon à contraindre les racines (3) des aubes dans une position fonctionnelle à l'intérieur du creux annulaire (7).
