Abstract

PURPOSE: To improve the productivity and prevent leak-out of lubricating oil, by internally fitting a metal bar for seal in a hollow metal core, and positioning a low melting point metal in the fitting part.
CONSTITUTION: Layers of copper or the like are plated on both inner and outer surfaces of a hollow metal core 4, and a solid or hollow metal bar 5 having layers of low melting point metal such as tin plated on the surface is internally fitted in a way to cover the tubular parts 4C, 4C at both sides of the core 4. The core main body B is held in a mold, with the shaft center P2 place concentrically to the crankshaft center P in journal parts 1, 1 and the shaft center P2 concentrically to the pin shaft center P3 in crank pin parts 3, 3, and casting is performed with ductile cast iron, with the core main body B being covered with inner chill, so as to form cocoon-shaped core parts A... in the journal parts 1, 1 and crank pin parts 3, 3. The plating layer is melted between the core 4 and the metal bars to form a hard solder state. Then, by providing a rail between the two parts, a seal to prevent leak-out of lubricating oil filled in the hollow part A may be achieved by casting.
