The crankshaft of the vehicle is one of the key parts of the vehicle engine during the operation. The performance of the diesel engine crankshaft will directly affect the quality and service life of the vehicle engine to a certain extent. The diesel engine crankshaft is running in the engine Maximum load and full power.
Diesel engine crankshaft in the work to withstand a strong direction of the changing moment and torque, but also with a long time high-speed operation of the wear and tear, so the crankshaft material has a high rigidity, fatigue strength and good wear resistance.
The main role of the diesel engine crankshaft is to effectively convert the reciprocating linear motion of the piston into a rotary motion through the connecting rod, which will, to a certain extent, effectively realize the conversion of its engine from chemical energy to mechanical energy.
Diesel engine crankshaft material is divided into two categories: First, steel forged crankshaft, the second is the ductile iron crankshaft, due to the use of casting method can be more ideal structural shape, thereby reducing the quality, and machining margins with the casting process level And reduced.
Diesel engine crankshaft in the production is the main use of its pouring cooling process using vertical pouring - vertical cold, oblique pouring - diagonal cold, oblique pouring - anti-oblique cold three pouring method is ideal, oblique pouring - anti-oblique cold is the advantage: Exhaust full, hot metal filling smooth, pouring system skimming effect is good, riser on the casting of the effect of good, to adapt to high-volume production line.
