Abstract

PURPOSE: To make the casting surface smooth and improve the fatigue strength, by forming the hollow part by inner chill of metal core.
CONSTITUTION: A low melting point metal, such as copper and tin, is provided on the outer surface of a hollow metal core 4 by plating or other method, and its inner surface is coated with heat-insulating heat-resistant film to prevent seizure. The core 4 is then filled with dry sand such as zirconium and silica sand, and is set in a mold using its tubular parts 4a, 4a as holding parts, with the shaft center P2 placed concentrically to the crankshaft center P in the journal part 1, and the shaft center P2 concentrically to the pin shaft center P3 in the pin part 3. With these cores 4... being covered with inner chill, casting is performed with ductile cast iron. After solidification, the castings are removed from the molds, and the filling dry sand is removed from the inner chill core 4. Thus, the hollow part A large in fatigue strength for torsion is provided in the journal part 1 and pin part 3.
