The fatigue strength is insufficient, which often causes the fracture of the connecting rod body or the connecting rod bolt, and further causes the serious accident of the complete machine damage. If the rigidity is insufficient, bending deformation of the rod body and out-of-round deformation of the large end of the connecting rod are caused, resulting in eccentric wear of the piston, the cylinder, the bearing, the crank pin and the like. The small end of the connecting rod is mostly of a thin-wall annular structure, and a thin-wall bronze bushing is pressed into the small end hole in order to reduce abrasion between the small end of the connecting rod and the piston pin. The small head and the bushing are drilled or milled to allow splashed oil droplets to enter the mating surfaces of the lubricating bushing and the piston pin.
