ABSTRACT:
A crankshaft of a ferro-metallic material for reciprocating engines, particularly for internal combustion engines, includes bearing pins and crank pins whereby the crank pins are delimited by webs extending transversely to a longitudinal center axis of the crankshaft which are constructed as counterweights. For optimizing the crankshaft as regards weight and structural length combined with good mass balancing, the crank pins are provided with hollow bores in the direction of their center axis and the counterweights with heavy-metal bodies.
