linkage group is composed of a connecting rod body, connecting rod, connecting rod bushing, cover the connecting rod bearing and rod bolts (or screws). The connecting rod group is subjected to the gas force of the piston pin and the action of the oscillation and the inertia force of the piston. Therefore, the connecting rod is subjected to cyclic loading such as compression and tension. Connecting rod must have sufficient fatigue strength and structural stiffness. The fatigue strength is not enough, often causes the connecting rod or the connecting rod bolt to break, then produces the entire machine to destroy the significant accident. If the stiffness is insufficient, it will cause the rod bending deformation and the big end of the connecting rod of the deformation, resulting in piston, cylinder, bearing and crank pin, eccentric wear.
