  • Patent number: 10337345
    Abstract: A sealing system for a multi-stage turbine includes multiple interstage seal segments disposed circumferentially about a turbine rotor wheel assembly and extending axially between a forward turbine stage and an aft turbine stage. Each of the interstage seal segments includes a forward end portion including an outer seal surface and an inner support face, an aft end portion, including an outer seal surface and an inner support face and a main body portion extending axially from the forward end portion to the aft end. The main body portion includes at least two support webs coupling the outer seal surfaces and the inner support faces. The outer seal surfaces are configured to be retained in a radial direction by a land support on each of a forward and aft stage turbine buckets, such that substantially all the centrifugal load from the multiple interstage seal segments is transferred to the forward and aft stage turbine buckets. A method of assembling the sealing system is disclosed.

  • Publication number: 20130236315
    Abstract: A torque transmission for a gas turbine rotor includes a plurality of adjacent rotating machine wheels. Each wheel includes a first flange on a first axial side and a second flange on a second axial side. The first flange has a plurality of first teeth extending around the circumference of the first flange and spaced by first slots, and the second flange has a plurality of second teeth extending around a circumference of the second flange and spaced by second slots. The first teeth of a first wheel are received in the second slots of a second, adjacent wheel to transmit torque through shear of the teeth and the first flange and the second flange are engaged to transmit torque through friction between the flanges.
