Abstract
A method for manufacturing a rotor shaft includes fabricating a first shaft portion that extends axially from a first end to a second end, fabricating a second shaft portion that extends axially from a first end to a second end, and coupling the second shaft portion to the first shaft portion with an explosive bonded joint such that the second shaft portion is aligned substantially concentrically with respect to the first shaft portion, and such that the bonded joint extends obliquely with respect to a centerline axis of symmetry of the rotor shaft.
Claims20
A method for manufacturing a rotor shaft, said method comprising:
- fabricating a first shaft portion that extends axially from a first end to a second end;
- fabricating a second shaft portion that extends axially from a first end to a second end;
- and
- coupling the second shaft portion to the first shaft portion with an explosive bonded joint such that the second shaft portion is aligned substantially concentrically with respect to the first shaft portion, and such that the bonded joint extends obliquely with respect to a centerline axis of symmetry of the rotor shaft.
A rotor shaft comprising a first shaft portion extending axially from a first end to a second end, and a second portion extending axially from a first end to a second end, said first shaft portion coupled to said second portion at a bonded joint such that said first shaft portion substantially axially-aligned with respect to said second shaft portion, said bonded joint extending obliquely with respect to a centerline axis of symmetry of said rotor shaft.
A gas turbine rotor shaft comprising a first shaft portion, a second shaft portion, and a bonded joint extending therebetween and substantially concentrically aligned with respect to said first and second portions, said bonded joint oblique with respect to a centerline axis of symmetry extending axially through said rotor shaft.
