GAS TURBINE SEALING BAND ARRANGEMENT HAVING A LOCKING PIN

摘要

A sealing band arrangement for a gas turbine including first and second adjoining rotor disks separated by a gap wherein the first rotor disk includes an aperture. The sealing band arrangement includes at least one seal strip segment located within the gap, wherein the seal strip segment includes a raised portion having a first mating surface. The sealing arrangement further includes a locking pin having a planar section for receiving the first raised surface. The locking pin also includes a pin section having a second mating surface that abuts against the first mating surface to thereby lock the locking pin and the seal strip segment together. Further, the pin section is located within the aperture to stop circumferential movement of the seal strip segment relative to first and second disks.

1. A sealing band arrangement for a gas turbine, wherein the as turbine includes first and second adjoining rotor disks separated by a gap and wherein the first rotor disk includes an aperture, comprising:
a seal strip segment located within the gap, wherein the seal strip segment includes a first raised portion that extends from the seal strip segment wherein the first raised portion includes a first mating surface; and a locking pin having a pin section that includes a second raised portion that extends toward the first raised portion, wherein the second raised portion includes a second mating surface that abuts against the first mating surface thereby locking the locking pin and the seal strip segment together and wherein the pin section is located within the aperture to stop circumferential movement of the seal strip segment relative to the first and second disks.
