SEALING ASSEMBLY AND SEALING MEMBER THEREFOR WITH SPLINE SEAL RETENTION

Abstract:

A sealing assembly includes a plurality of sealing members configured to be located circumferentially adjacent one another between adjacent rotating blade stages in a turbine. The sealing members include axially extending sealing portions having spline seal slots defined in opposing slash faces thereof. The slots are structured to allow insertion of a spline seal into facing slots on adjacent sealing members when the sealing members are in an axially offset position, and to retain the spline seal in the facing slots when the sealing members are moved to an operative axial position. The slots may include spline seal-retaining seats therein to properly position and retain the spline seal. The sealing members allow easy assembly of the sealing assembly with proper positioning of the spline seal, and without damaging the spline seal or adjacent structure. A method assembling the sealing assembly is also disclosed.
