FIELD: machine engineering.
SUBSTANCE: turbine contains a number of stages, each of which includes a disk and blades located on it. A pair of adjacent discs forms an annular gap therebetween and has opposite slots for receiving a sealing tape to seal the annular gap. A through hole is formed in the sealing tape, located midway between the edges of the sealing tape. Between the edges of the sealing strip within the annular gap is a base portion of the rotation preventing member, which also includes a connecting portion extending axially from the base portion to engage with a cutout portion of at least one of the discs. Inside the annular gap, from the base portion, via the through hole in the sealing strip, protrusion forms a fastening structure that attaches the rotation-preventing member to the sealing tape.
EFFECT: invention makes it possible to prevent the sealing tape from moving around the circumference.
