Abstract
PURPOSE:To provide an equal performance to the forged crankshaft, by setting a steel pipe in the place of a casting mold, constructing journal and crankpin part, pouring a molten metal of ball-shape graphite cast iron into the casting mold, and constructing the both described porions in the above. CONSTITUTION:To the place in a casting mold, corresponding to a journal part 2 and a crank part 3, are engaged a plurality of steel pipes 4, 5, respectively, thereafter, is poured a molten metal of ball-shape graphite iron to construct a sliding portion of th journal part 2 and the crank pin part 3 by the pipe 4, 5. For the pipe if used a steel pipe of low amount of carbon content, by a heat treatment processed at casting operation or after casting, crabon in the cast iron is diffused in the pipe, and a carbon content in the pipe comes to be the same extent of that in the forged crankshaft. Further in an operation of the crankshaft, a seizure can be eliminated in the contact portion with bearing metal.
