Beschreibung
Zusammenfassung:	A connecting rod ( 1 ) has a small connecting rod eye ( 2 ) and a large connecting rod eye ( 3 ). A bearing shell ( 4, 5 ) is disposed in at least one connecting rod eye ( 2, 3 ), wherein the bearing shell ( 4, 5 ) is held in the connecting rod eye ( 2, 3 ) for secure mutual rotation therewith. To obtain good adhesion of the bearing shell ( 4, 5 ) in the connecting rod eye ( 2, 3 ), the bore surface ( 12, 13 ) in one connecting rod eye ( 2, 3 ) and/or the outer surface of a bearing shell ( 4, 5 ) has/have a structure ( 6, 7, 24, 26, 28, 30, 32, 34, 37, 38 ), wherein the structure ( 6, 7, 24, 26, 28, 30, 32, 34, 37, 38 ) is formed by elevations ( 9 ), the elevations ( 9 ) delimiting the outer periphery of depressions ( 8 ). In a method for producing a connecting rod ( 1 ) comprising at least one connecting rod eye ( 2, 3 ) with a structured surface ( 12, 13 ), wherein a bearing shell ( 4, 5 ) is disposed in the connecting rod eye ( 2, 3 ) after structuring of the surface, the surface ( 12, 13 ) is structured with a laser.
