| description | The present invention relates to a crank-drive with a crank-shaft, at least one connecting rod and at least one piston, in particular a crank-drive of an internal combustion engine, whereas the crank-shaft features at least one radial bearing (13) for supporting the crank-shaft in a crank-housing, at least one radial bearing for connecting the connecting rod to the crank-shaft, and the connection of the connecting rod to the piston features at least one radial bearing and whereas the bearings feature a bearing inner surface and/or a bearing outer surface. According to the invention in at least one of the bearing surfaces are arranged micro-ramp structures with an asymmetric form having a first concave section between the bearing surface and a bottom point of the micro-ramp structure and a second concave section between the bottom point and the bearing surface, whereas between the micro-ramp structures are arranged sections of the bearing surface. |
