Abstract: A locating plate for locating a first piece of rotary machinery relative to a second piece of rotary machinery is provided. The plate has a first periphery surface for mating with a first receiving surface of the first piece of rotary machinery and a second periphery surface for mating with a second receiving surface of the second piece of rotary machinery. The plate also has at least one attaching device for use in attaching the plate to the first piece of rotary machinery and at least one removal device for use in removing the plate from the first piece of rotary machinery. The plate is removably attachable to the second piece of rotary machinery, and the second periphery surface is sizable independently from the first periphery surface.

Abstract: In a steam turbine, a combined brush and labyrinth seal is provided between a diaphragm web and axial projecting platforms on bucket dovetails at a location spaced radially outwardly of the outer diameter of the rotor. The downstream axially adjacent bucket dovetails also have platforms serving as complementary sealing surfaces to labyrinth teeth formed on the web. By locating the combined labyrinth and brush seal radially outwardly of the outer diameter of the shaft, thermal bowing of the rotor is eliminated. By providing backup labyrinth seals at the same radial location, axial thrust loads are eliminated in the event of brush seal failure.

Abstract: A turbine shell assembly includes radially inner and outer shell components; axial alignment fits on the inner and outer shell components, each alignment fit comprising a male fit component on one of the inner and outer shell components and a female fit component on the other of the inner and outer shell components, the female fit component comprising a pair of flanges forming a U-shaped channel with opposed faces, and the male fit component comprising a projection received within the U-shaped channel; and a pair of axial alignment keys, each key having a mounting flange for securement along an outer edge of a respective one of the pair of flanges and an alignment flange engaged along a respective one of the opposed faces.
