    • 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.
    • 连杆(1)具有小连杆眼(2)和大连杆眼(3)。 轴承壳体(4,5)设置在至少一个连杆眼(2,3)中,其中所述轴承壳体(4,5)保持在所述连杆眼(2,3)中,以与所述连接杆眼(2,3)保持相互旋转。 为了在连杆眼(2,3)中获得轴承壳(4,5)的良好的粘附力,一个连杆眼(2,3)中的孔表面(12,13)和/或一个连杆眼 轴承壳体(4,5)具有/具有结构(6,7,24,26,28,30,32,34,37,38),其中所述结构(6,7,24,26,28,30,38,38,38) 32,34,37,38)由凸起(9),限定凹部(8)的外周的高度(9)形成。 一种用于生产连杆(1)的方法,连杆包括至少一个具有结构化表面(12,13)的连杆眼(2,3),其中轴承壳(4,5)设置在连杆眼( 2,3),在构造表面之后,表面(12,13)由激光器构成。
