Tungsten alloy bar for crankshaft has high melting point, good abrasion resistance and corrosion resistance, which is the suitable material choice for making automobile crankshaft. The crankshaft made by it has sufficient strength and stiffness, the surface of the shaft neck is wear-resistant, the work is uniform, and the balance is good.
Crankshaft is one of the most typical and important parts of the engine. Its ding is to transform the gas pressure transmitted by piston connecting rod into torque, output power as power, drive other working mechanism and drive auxiliary equipment of internal combustion engine. This means dramatic acceleration and deceleration accompanied by high bending deformation, high torque and vibration shocks, which results in very high and variable stresses. Such extreme stresses require careful design and calculation, selection of suitable materials and batch processing techniques.
