Summary: | The impeller is provided with: a disc section equipped with a tubular section, the grip section of which is fixed by thermal deformation to a rotation shaft that is rotated around the axis line, and a main disc body, which is provided on the other end in the axial direction from the grip section and which extends outward in the radial direction of the rotation shaft; and blade sections that protrude from the main disc body in the axial direction. The disc section is provided with a hoop stress-limiting section, the tubular section of which extends further towards the other end in the axial direction than the main disc body.
L'invention porte sur une roue à aubes qui est pourvue : d'une section disque équipée d'une section tubulaire, dont la section de prise est fixée par déformation thermique à un arbre de rotation qui est rotatif autour d'une ligne d'axe, et d'un corps principal de disque qui est placé sur l'autre extrémité dans la direction axiale de la section de prise et qui s'étend vers l'extérieur dans la direction radiale de l'arbre de rotation ; de sections aubes qui font saillie du corps principal de disque dans la direction axiale. La section disque comprend une section de limitation de tension de charge, dont la section tubulaire se prolonge plus loin vers l'autre extrémité, dans la direction axiale, que le corps principal de disque. |
