    摘要： The impeller axial lock limits axial movement of an impeller disposed on a shaft. The impeller is spaced axially from a shaft sleeve disposed about the shaft. The impeller axial lock includes a ring member disposed about the shaft between the impeller and shaft sleeve. The ring member has a body defining a first engagement tab engaging the impeller, a second engagement tab engaging the shaft, and a third engagement tab engaging the shaft sleeve. The shaft sleeve secures the ring member to the shaft via the third engagement tab such that the ring member limits axial movement of the impeller on the shaft during rotation of the impeller. The second engagement tab engages a groove in the shaft, and the third engagement tab engages a groove in the shaft sleeve.

    摘要： A rotor component for a rotor assembly of a fluid energy machine, particularly of a gas turbine, a steam turbine, a compressor or the like, wherein the rotor component is at least partly made of a material susceptible to corrosion and/or oxidation and can be arranged concentrically to a rotation axis of the rotor assembly. The rotor component includes a circular surface for checking concentricity of the rotor component with respect to the rotation axis. The rotor component includes at least one additional circular surface for checking concentricity of the rotor component with respect to the rotation axis, wherein the additional circular surface is coated with a corrosion and/or oxidation protection coating.

    摘要： An object is to provide a rotational body in which a gap is not formed between a rotational shaft and an impeller even during rotation at high speed in the interference fit portion between the rotational shaft and the impeller, and in which misalignment between the center positions of the rotational shaft and the impeller does not arise, and a manufacturing method thereof. A rotational body includes a rotational shaft 2, an impeller 3, and a nut 6. The impeller includes a hub portion 4 having a peripheral surface 4s inclined to the axial direction of the rotational shaft and having an insert hole 4h in which the rotational shaft is inserted, and a blade portion 5. At least one of the rotational shaft or the insert hole of the hub portion has an interference fit portion 10 for fit between the rotational shaft and the impeller, where the outside diameter of the rotational shaft is larger than the inside diameter of the insert hole of the hub portion. The interference fit portion is formed in a region which does not include the largest outside diameter portion 4B where the hub portion has a largest outside diameter, with the rotational shaft and the impeller mating with each other.

    摘要： A compression system may include a compressor having first and second sides separated by a division wall, first and second shafts, and first and second radial bearings. The first and second shafts may be axially connected to each other at respective first ends via a rotor portion of an intermediate radial bearing. The rotor portion may include a plurality of laminations stacked between first and second plates fastened to each other. The first radial bearing may be disposed on a first side of the intermediate radial bearing and may be proximate a second end of the first shaft. The first radial bearing may be configured to support the first shaft. The second radial bearing may be disposed on a second side of the intermediate radial bearing and may be proximate a second end of the second shaft. The second radial bearing may be configured to support the second shaft.
