Crankshaft rotational support arrangement for an internal combustion engine

摘要

A crankshaft rotational support for an internal combustion engine having a crankshaft supported by rotational support elements spaced from one another along the longitudinal direction of the internal combustion engine is provided. The crankshaft rotational support includes a plurality of bearing blocks and a plurality of bearing covers. Stiffening elements extend longitudinally for interconnecting H-shaped side projections of the bearing covers to one another. The bearing blocks, the bearing covers, and the stiffening elements collectively form a unit which is cast as an integral unit during a casting process with the cast bearing covers and the cast bearing blocks being separable from one another along a break line. The side projections and the stiffening elements each have an open profile that does not comprise any fully encircled apertures in which a casting sand core may remain after casting.
