摘要:
A multi-piece crankshaft is disclosed having a shaft with two ends and in which the shaft is adapted to rotate about its shaft axis. A crankpin also has two ends and an axis parallel to but spaced radially outwardly from the shaft axis. The crankpin optionally has at least one indentation. A plate has two spaced openings such that one end of the shaft is positioned in one of the plate openings while one end of the crankpin is placed in the other plate opening. The shaft also includes at least one indentation at a position adjacent its other end. The shaft and crankpin are placed within a mold so that the plate is positioned within a first mold cavity corresponding in shape to the desired counterweight. Simultaneously, the indentation adjacent the other end of the shaft is positioned within a second mold cavity corresponding in shape to a flywheel taper support for the crankshaft. The counterweight and flywheel taper support are then both formed by simultaneously casting a liquid material, such as zinc, into both the first and second mold cavities. Upon cooling, the molten material solidifies thus simultaneously forming the counterweight and flywheel support taper.
