Precision-Machined Impact-Resistant Drive Shaft

As the initial power receiving component of the transmission system, the input shaft undertakes the key responsibility of introducing the power source torque into the transmission link, with core advantages of large transmission torque and impact resistance. Its transmission torque performance is optimized, using 42CrMo high-strength alloy steel for integral forging, the shaft diameter is optimized through finite element analysis, the torsion section coefficient is increased by 25%, and the rated transmission torque is more than 30% higher than that of conventional shafts of the same specification, which can stably undertake high-power power input. In terms of impact resistance, after integral quenching and tempering + surface quenching composite process treatment, the shaft hardness reaches HB280-320, the impact toughness of key stress-bearing parts is ≥85J/cm², and with shaft shoulder fillet transition strengthening, it can effectively resist instantaneous impact loads during power…
