1,High strength and toughness:The forged steel gives the crankshaft excellent strength and toughness. In the complex and high-intensity working environment of excavator engines, the crankshaft needs to bear huge torque and alternating load.
2,High precision machining:Crankshaft machining precision is extremely high. The diameter tolerance, cylindricity, roundness and surface roughness of the spindle journal and connecting rod journal are strictly controlled within a very small range.
3,Good wear resistance:Due to the high-speed relative motion and large pressure between the crankshaft and the bearing during the working process, its surface needs to have good wear resistance. 8DC9 ME996186 Forged steel crankshafts may have special surface treatments.
4,Dynamic balance optimization:The balance of the crankshaft during rotation is crucial. This crankshaft has been optimized for dynamic balance in the design and manufacturing process.
