Abstract: Various embodiments include a rotor key member, along with a related assembly and steam turbine. Particular embodiments include a rotor key member for retaining a circumferential seal in a steam turbine, the rotor key member including: a main body; a first arm extending from the main body; a second arm extending from the main body, wherein the first, arm, the second arm and the main body define a space spanning axially between the first arm and the second arm; and a hook extending from the second arm in a direction axially away from the space, the hook sized to contact a radially inner surface of the circumferential seal.

Abstract: Various embodiments include a rotor key member, along with a related assembly and steam turbine. Particular embodiments include a rotor key member for radially retaining a circumferential seal in a steam turbine rotor body, the rotor key member including: a main body sized to contact an axial face of the circumferential seal; and a hook extending from the main body in a direction axially away from the circumferential seal, the hook sized to substantially complement a corresponding shelf in the steam turbine rotor body to restrict movement of the circumferential seal relative to the steam turbine rotor body.

Abstract: Various embodiments include a rotor key member having: a body with a primary axis extending in a direction substantially perpendicular to an axial direction in a steam turbine, the body including: a first pair of opposing sides; a second pair of opposing sides extending between the first pair of opposing sides; a top surface and a bottom surface extending between the second pair of opposing sides; and a fillet, bevel or chamfer edge extending between a first one of the first pair of opposing sides and the bottom surface and extending an entire length of the body along the primary axis; and a slot within the body, the slot extending a portion of a length of the body along the primary axis between the second pair of opposing sides and forming an opening in a second one of the first pair of opposing sides.

Abstract: Various embodiments include a rotor key member, along with a related assembly and steam turbine. Particular embodiments include a rotor key member for circumferentially retaining a circumferential seal in a steam turbine rotor body, the rotor key member having: a main body sized to contact an axial face of the circumferential seal; and a locking member extending from the main body in a direction axially toward the circumferential seal, the locking member having at least one circumferential edge sized to substantially complement a corresponding slot in the circumferential seal to restrict movement of the circumferential seal relative to the steam turbine rotor body.
