Title:

INTERSHAFT SEALING SYSTEMS FOR GAS TURBINE ENGINES AND METHODS FOR ASSEMBLING THE SAME

Document Type and Number:

Japanese Patent JP2017210954

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide intershaft sealing systems for gas turbine engines and methods for assembling the same.SOLUTION: A seal assembly for use between an inner shaft (108) and an outer shaft (106) rotatable about a common axis (12) within a turbine engine (10) includes a pair of end rings (122, 124) and a plurality of seal elements (126) coupled between the pair of end rings. Each end ring includes flanges (134, 136) extending in an axial direction, and each seal element includes a pair of shoulders (170, 172) extending in opposing axial directions. The seal assembly also includes a pair of retaining rings (128, 130). Each retaining ring is positioned between one shoulder of the pair of shoulders and a corresponding one end ring flange of the pair of end ring flanges.SELECTED DRAWING: Figure 3
