More Information
Summary:The invention is related to a rotor key member (20) and a related steam turbine rotor assembly (22). The rotor key member (20) for circumferentially retaining a circumferential seal (24) in a steam turbine rotor body (46) comprises a main body (26), sized to contact an axial face (56) of the circumferential seal (24), and a locking member (28), extending from the main body (26) in an axial direction toward the circumferential seal (24). The locking member (28) has at least one circumferential edge (29) sized to complement a corresponding slot (30) in the circumferential seal (24) to restrict movement of the circumferential seal (24) relative to the steam turbine rotor body (46).
