Crankshaft Assembly,High Performance Crankshaft,Auto Crankshaft Assembly,Truck Crankshaft Assembly
Crankshaft is the core of the power end, it is the key transmission components of mud pump, more an important safety component. Crankshaft must have sufficient rigidity and fatigue strength. Therefore, the crankshaft is made of ZG35CrMoRe through precision casting. The material has an excellent mechanical properties after post-strengthening treatment. High strength, toughness and fatigue resistance, improves the service life of the crankshaft. To reduce the weight, The crankshaft is hollow. The three throws on crankshaft are equipped with eccentric bearings, the connecting rod big end is mounted on the eccentric Bearing. The crankshaft rotation drives the connection rod to come true reciprocating motion.
