Abstract

PURPOSE:To improve the characteristics of a rotor by securing a flange formed by casting and enclosing a rotor shaft formed by compositely forming aluminum alloy and carbon or silicon carbide fiber in an aluminum alloy plate to both ends of a rotor body formed of a light metal material. CONSTITUTION:A flange 1 which forms the end of a rotor is formed by casting and enclosing a rotor shaft 2 formed by compositely forming aluminum alloy and carbon or silicon carbide fiber in an aluminum alloy plate 3. A rotor body 4 is formed of an Al-Si alloy which has high thermal resistance and wear resistance such as AC8A or AC9A. The flange 1 and the body 4 are inserted into a die 5 of a forging machine, forged by a press 6, and the flange 1 is pressed to the body 4. Thus, a rotor which has a light weight, high thermal strength and a durability for high speed rotation can be obtained.
