Located in an environment with high temperature, high pressure, and abundant oil pollution inside the engine, it has good resistance to high temperature and corrosion.
Perform quenching and other heat treatments on key parts such as the shaft neck to improve surface hardness and wear resistance, and extend service life.
The roundness, cylindricity, and surface roughness of the main journal and connecting rod journal are strictly controlled, with an accuracy of micrometers to ensure smooth operation.
On the premise of ensuring strength, weight reduction can be achieved by optimizing the shape of the crank arm and reducing the size of non stress areas to improve engine response speed.
The metal streamline of forged crankshaft is distributed along the contour of the crank arm, consistent with the direction of force, which can fully exert the mechanical properties of the material and has higher torsional strength and fatigue resistance than cast crankshaft.
