    摘要: A device for changing and attaching or mounting an angle of stationary vanes of an axial-flow fluid machine by rotating the stationary vanes through a circumferential movement of an intermediate cylinder. The device includes at least one arm secured to one end of the intermediate cylinder and engaging at a second end in a groove formed in a block member which is attached to an end of an actuator and is movable in a tangential direction of the intermediate cylinder. A guide arrangement is provided for guiding a movement of the block member and at least a portion of the actuator so as to ensure a smooth operation of the actuator by freeing the same from any influence of undesireable forces such as lateral pressure caused by a thermal expansion of the intermediate cylinder.

    摘要: 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.
