Abstract

PURPOSE: To improve the reliability of a rotor during production of a high Cr steel turbine rotor by forming a rotor terminal by forging into an axle coupling section after a journal sleeve section is shrinkage fitted.
CONSTITUTION: A rotor material is formed by forging and is machine-worked, next a rotor journal 1a is worked, and a package type journal sleeve 2a is shrinkage fitted. The shape of both ends of a rotor 1 at this time is the status of a rotor 1b before forging, and a final machine work margin is left around the journal sleeve 2a. After this shrinkage fitting, a portion of the rotor 1b is heading forged to make up a final coupling 3a in one body. Therefore, fretting corrosion or stress corrosion never occurs and the reliability is high.
