A rotor of an axial-flow machine including a plurality of spacer members arranged peripherally of the rotor for providing a channel on the surface of the rotor. The spacer members are located in a manner to straddle the forward stage disc section and the rearward stage disc section, to enable each rotor blade to be replaced individually with a new one by mounting and removing the rotor blade axially of the rotor. The rotor of the axial-flow machine has improved reliability and flow performance.

A rotor of an axial-flow machine comprising a plurality of rotor blades arranged in a stator blade lattice and supported on disc sections in a manner to be mounted and removed as desired, said rotor comprising a stacked-rotor including a plurality of discs stacked one over another and interconnected by stacking-bolts, said rotor further comprising: a plurality of circumferential grooves located peripherally of the rotor on opposite outer peripheral surfaces of the adjacent disc sections in spaced juxtaposed relation; spacer means including a plurality of spacer members located peripherally of said circumferential grooves and outer surfaces each forming a channel on the surface of the rotor juxtaposed against the end of each stator blade; projecting portions each divided into a plurality of elements peripherally of each said circumferential groove to be successively fitted therein to keep said spacer means from being dislodged outwardly of the rotor by engaging the outer peripheral shoulder of each said circumferential groove; cutout means formed at least in one portion of each said circumferential groove and having a length slightly greater than the peripheral length of each said spacer member to allow the spacer members to be successively inserted therethrough into the circumferential grooves; and means for avoiding dislodging of a last spacer member inserted in the circumferential grooves through said cutout means, said last spacer member dislodging avoiding means being located both in the last spacer member and the disc section.
