Abstract

L'invention concerne un banc d'essai (10) pour un rotor (12), notamment un rotor de turbomachine, dans lequel le rotor (12) comporte un tourillon (14) consistant en une pièce de révolution possédant des cannelures (16) sur une face cylindrique radialement externe et le rotor (12) comporte une bride (20) située à une extrémité axiale aval (22) du tourillon (14), le banc d'essai (10) comportant un axe principal A, une structure fixe et un arbre de support (28) consistant en un élément creux de révolution coaxial à l'axe principal A, qui est monté à rotation autour de l'axe principal A par rapport à la structure fixe, caractérisé en ce que l'arbre de support (28) délimite un logement creux (36) ouvert vers l'aval dans lequel le tourillon (14) est apte à être inséré et fixé selon un mouvement de translation de l'aval vers l'amont le long de l'axe principal A. Figure pour l’abrégé : figure 1The invention relates to a test bench (10) for a rotor (12), in particular a turbomachine rotor, in which the rotor (12) comprises a journal (14) consisting of a part of revolution having grooves (16) on a radially external cylindrical face and the rotor (12) comprises a flange (20) located at a downstream axial end (22) of the journal (14), the test bench (10) comprising a main axis A, a fixed structure and a support shaft (28) consisting of a hollow element of revolution coaxial with the main axis A, which is mounted for rotation around the main axis A relative to the fixed structure, characterized in that the shaft of support (28) delimits a hollow housing (36) open towards the downstream in which the pin (14) is able to be inserted and fixed in a translational movement from downstream to upstream along the main axis A.
