Product Description

      High Quality Carbon Steel Hot Die Forging Auto Crankshaft Main Crank Shaft for Diesel Engine Parts

Product 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 specification:
       1. Carbon & low alloy steel;
       2. Stainless steel;
       3. High alloy & wear resist steel;
       4. Gray iron; Ductile iron;
       5. Malleable iron;
       6. Alloyed cast iron;
       7. Aluminum alloy;
       8. Cooper alloy;
       9. Zinc alloy

       Specifications:
       1. ISO9001: 2000 certification
       2. TUV (PED 97/23/EC & AD2000 aa W0/TRD 100) certification
       3. Professional OEM manufacturer
       4. Process: Precision made. Experience & Reasonable QC that you can reply on Each part would be
       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.
