Abstract
In order to reduce friction of a crank shaft during operation by a large amount with low complexity through structuring sliding bearing surfaces () of the crank shaft through controlled introduction of microscopically small indentations () it is proposed for the center bearings and the crank bearings to only structure highly loaded portions of the bearing surface in circumferential direction and also in axial direction since this is already difficult to achieve in view of the operating gap towards the tool that only has a size of a few μm.
