Abstract
A crank drive has a crankshaft having at least one crank pin having a bearing surface with a concavely curved shape in a longitudinal crankshaft section and a conrod having a big end fitted to the crank pin and having a bearing surface with a convex shape in contact with the concave shape of the bearing surface of the crank pin in a load-bearing area that transmits forces acting between the big end of the conrod and the crank pin when the drive is in use. The shapes of the bearing surfaces are in accordance with the principle of uniformly distributed stresses such that essentially the same equivalent stress is distributed overall in the bearing surfaces in time average.
