Collaborative application of heat treatment technology and advanced design software: solving core problems in power transmission.
The failure of power transmission systems (such as gear tooth surface peeling, shaft component fracture, early bearing wear, etc.) is often related to mismatched material properties, residual stress concentration, and unreasonable structural design. By optimizing material properties through heat treatment technology and combining simulation analysis with design software, these problems can be solved from the root.
1. Heat treatment technology: precise control of material properties to match transmission requirements
Carburizing quenching+low-temperature tempering: used for parts such as gears and transmission shafts that withstand alternating loads. By carburizing at 900-950 ℃ (carbon concentration gradient controlled at 0.8-1.2%), quenching at 850-880 ℃ (oil/water mist cooling), and tempering at 150-200 ℃, the surface hardness can reach HRC 58-62 and the core hardness can reach HRC 30-40, balancing surface wear resistance and core toughness, and increasing contact fatigue life by more than 40%.
Induction hardening+self tempering: suitable for local strengthening of shaft parts (such as flower keys and shaft necks). By using medium frequency induction heating (frequency 10-100kHz), the surface layer of 5-10mm is rapidly heated to above Ac3. After water spraying cooling, the residual heat is used for self tempering, which can reduce deformation (≤ 0.1mm/m) and meet high-precision matching requirements.
Time hardening treatment: For aluminum alloy transmission housings (such as motor reducer housings for new energy agricultural machinery), the hardness is increased from HB 60 to HB 110 through solid solution treatment (530 ℃× 2h)+artificial aging (120 ℃× 8h), and the tensile strength reaches over 300MPa, achieving a balance between lightweight and high strength.
