Precision Engineered Transmission Shaft Parts

As the core of cross-component power transmission in the transmission system, the through shaft undertakes the responsibilities of long-distance torque transmission and power distribution, and has two core advantages: large transmission torque and impact resistance. The large transmission torque is remarkable, using 42CrMo high-strength alloy steel for integral forging, the shaft diameter is optimized by finite element analysis, the torsion section coefficient is increased by 25%, and the rated transmission torque is more than 30% higher than that of ordinary shafts of the same specification, which can stably carry high-power power flow. The impact resistance is outstanding. After overall quenching and tempering + surface quenching treatment, the shaft hardness reaches HB280-320, the impact toughness of key stress-bearing parts is ≥85J/cm², and with the shaft shoulder fillet transition strengthening design, it can resist instantaneous impact loads during vehicle shifting and constructi…
