OEM Auto Forging Truck Engine Axle Crank ShaftProduct
Description The crankshaft is the most important part of the
engine. It bears the force from the connecting rod and converts it
into torque, which is output through the crankshaft and drives
other accessories on the engine. The crankshaft is subjected to the
combined action of centrifugal force of rotating mass, periodic gas
inertia force and reciprocating inertia force, which makes the
crankshaft bear the bending and torsional load. Therefore, the
crankshaft is required to have sufficient strength and
stiffness,and the journal surface shall be wear-resistant, work
evenly and have good balance. Material

given 100% test and tryout before shipment. 5. Adequate
supply capacity. Punctual delivery time.The stress of crankshaft is
extremely complex. It works under the joint action of periodically
changing gas pressure, reciprocating inertia force and its torque,
and bears huge alternating bending and torsion loads. At the same
time, it is also a slender high-speed rotating part, so it needs
strict dynamic balance, and bending and distortion are not allowed
to exceed a certain value. Therefore, our crankshaft needs to be
made of very high-quality materials and undergo strict surface
treatment process. 45, 40Cr, 35Mn2 and other medium carbon steel
and medium carbon alloy steel are generally used for die forging,
and nodular cast iron is also used more in recent years. After
forging or casting, in order to improve the fatigue strength of the
crankshaft and eliminate stress concentration, shot peening shall
be carried out on the journal surface, and the fillet shall be
rolled; In order to improve the surface hardness of the journal, it
is also necessary to do high-frequency quenching or nitriding
treatment on the journal surface, and finally finish machining. The
crankshaft treated in this way has sufficient fatigue strength and
stiffness against bending and torsion, and the journal has large
enough pressure bearing surface and wear resistance. It ensures the
high hardness and accurate size control of the crankshaft. Enable
users to have a good use feeling.Features:custom forgings
