Title:
高圧および低圧タービンの内部領域を分離させる構造
Document Type and Number:
Japanese Patent JP2008513661
Kind Code:
A
Abstract:
Convex sealing bottom (10) for a twin-shaft turbine of the type comprising a series of convex disks constrained to each other by means of a series of pins, each disk of said disks comprises an outer shaped edge which is engaged with a corresponding annular surface (71) of an inner grooved surface (72) of a ring (70) for obtaining an axial seal. The series of disks comprises three disks, a first disk (12), a second disk (13) and a third disk (14) respectively. The three disks are fixed to each other centrally by means of a series of spokes (30) and are constrained in pairs respectively by means of a series of pins which are arranged orthogonally to the three disks to minimize the relative movements of the three disks in an axial direction at the same time allowing the radial dilatations of the three disks themselves.
