Abstract

PURPOSE: To improve the bearing properties of the journal of a rotor made of high-chromium-content steel, by fitting the journal with a cylindrical sleeve made by welding a plurality of segments made of metal of high bearing properties.
CONSTITUTION: A plurality of sleeve segments 1 made of a metal of higher bearing property than a rotor made of high-chromium-content steel consisting essentially of martensite are welded on each other to manufacture a cylindrical sleeve 4 of smaller inside diameter than the journal 3 of the rotor. The sleeve 4 is thereafter fitted to the journal 3 as the sleeve is maintained at a prescribed temperature. This results in heightening the reliability of the rotor.
