摘要

Crankshaft for combustion engines, which consists of a number of components (1, 2) joined to each other. The crankshaft has hollow main bearing journals (8) and crank bearing journals (11) with radial bores (12, 13) which open into the cavities (14, 15) of the journals. The main bearing journals and the crank bearing journals have oil ducts in the form of steel tubes (17) which extend through the cavities and join the bores in the main bearing journals and the bores in the crank bearing journals pairwise to each other.
