  • Patent number: 6648540
    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.

  • Patent number: 6250640
    Abstract: A number of sealing segments 20 mounts a brush seal about a rotor. The tips of the brush seal 46 are maintained out of contact with the rotor surface throughout the entire operating range of the turbomachinery. Thus, the increase in temperature resultant from rubs between the bristle tips and the rotor 12 which effectively increase vibrations of the turbomachinery are eliminated. Brush seals are therefore maintained out of contact with the rotor throughout the entire operating range of the turbomachinery and thus do not affect the dynamic behavior of the rotor.

  • Patent number: 5482380
    Abstract: A double tilting pad journal bearing includes a substantially cylindrical, open ended beating casing having a longitudinal axis extending therethrough, an interior surface of which supports a plurality of beating liner pads for circumferential and axial tilting movement relative to the casing and to the longitudinal axis. The casing is formed with a pair of annular oil feed grooves in the exterior surface thereof communicating with the interior of the bearing casing by a plurality of radially directed feed passages. The interior surface is also formed with at least one oil drain annulus in communication with at least one radially oriented drain port. Annular seals are fitted within grooves at opposite ends of the bearing casing. The bearing liner pads are secured within the casing by a sliding tongue and groove fit which nevertheless permits tilting of the pads both circumferentially and axially.
