摘要： A turbine rotor improved in machinability, appropriately balanced in stress, and having rotor hooks and rotor necks constructed to form an attachment structure with respect to an inverted fir tree blade root that has blade hooks and blade necks. The turbine rotor has rotor hooks and rotor necks constructed to form an attachment structure with respect to an inverted fir tree blade root that has blade hooks and blade necks with an “n” number of hooks, where n≧3. In this structure, a convex portion of the innermost circumferential rotor hook is formed to be concave in a circumferential direction, with respect to a tangential line that connects a convex portion of the (n−1)th hook from the outermost circumferential rotor hook, and a convex portion of the (n−2)th hook.

摘要： In a turbine rotor, a rotor radial-direction hook length (Hri) of an i-th rotor hook counting from the outermost circumference of the rotor and a blade radial-direction hook length (Hbi) of an i-th blade hook counting from the outermost circumference of the blade are set to satisfy the relationship of (Hri>Hbi). In the turbine blade, a rotor circumference-direction neck width (Wri) of an i-th rotor neck counting from the outermost circumference of the rotor and a blade circumference-direction neck width (Wbi) of an i-th blade neck counting from the innermost circumference of the blade are set to satisfy the relationship of (Wri>Wbi).
