From the perspective of material and process optimisation, the transmission gear shaft is a high-performance transmission
component crafted through the integration of advanced material selection and precision manufacturing techniques,
designed to enhance overall performance through the synergistic improvement of materials and processes.
Characterised by highly targeted material selection (e.g., high-strength alloy steels, carbon fibre composites)
and integrated manufacturing processes (combining forging, heat treatment, and precision machining).
Advantages include high specific strength, excellent wear resistance, and extended fatigue life.
This approach meets performance requirements while reducing material consumption, offering robust process stability
and high product consistency.
Materials are selected according to transmission requirements—for instance, 20CrNiMo alloy steel for heavy-duty applications
and carbon fibre-reinforced resin matrix composites for lightweight scenarios. Isothermal forging enhances material density,
while carburising and quenching treatment strengthens tooth surface hardness. Precision grinding ensures gear profile accuracy,
enabling the shaft to deliver both high strength and exceptional wear resistance during transmission.
Suitable for equipment demanding stringent material performance, including transmission gear shafts in aero-engines,
drive gear shafts in new energy vehicles, spindle gear shafts in high-end CNC machine tools, and corrosion-resistant gear shafts
in marine engineering equipment.
