The working principle of the connecting rod assembly is to change the circular motion of the crankshaft into horizontal or vertical reciprocating motion.
The connecting rod assembly mainly includes: connecting rod body, big end bearing shell, small end bearing shell, connecting rod bolts and nuts.
The main materials of the connecting rod body are 35#, 45#, QT600, 40Cr or 42CrMoE.
The main material of the big end bearings are Aluminum alloy and 45# / 11-6; And 10-1.6-6-3.Aluminum alloy and 45#/11-6 for the small end bearings; We choose 40Cr, 35CrMoAlA or 42CrMoE materials for forging and tempering process to produce connecting rod bolts.
