Beschreibung
Zusammenfassung:	A crank drive includes a crankshaft journal having a concave-shaped surface, a bearing element in which the crankshaft journal is rotatably mounted, and a bearing shell disposed between the crankshaft journal and the bearing element and having a first convex-shaped surface matched with the concave-shaped surface of the crankshaft journal. The bearing shell has a second surface associated with the bearing element and is constructed such that the bearing shell has a non-constant cross section in the longitudinal direction of the crankshaft journal. The bearing element surface facing the bearing shell is adapted to the second surface of the bearing shell regarding the shape of the bearing element surface, and the second surface of the bearing shell is cylindrical or concave and has a smaller curvature than the concave-shaped surface of the crankshaft journal.
