Precision Planetary Gear Shafts for New Energy Vehicle Differentials
Advanced Surface Engineering for Electrified Powertrains
Our planetary gear shafts are engineered specifically for high-torque, high-efficiency differentials in electric and hybrid vehicles. Featuring ultra-precise CNC machining (≤0.01mm tolerance), these critical components deliver exceptional fatigue resistance under extreme NEV operating conditions.
Surface Treatment Options:
Nickel Plating - Enhanced corrosion resistance & wear durability
Phosphating - Superior anti-galling properties and oil retention
QPQ (Quench-Polish-Quench) - Optimized combination of hardness (≥500HV), friction reduction, and salt spray resistance (300h+)
Technical Advantages:
⚙️ Material: High-grade alloy steel (20MnCr5/8620 equivalent)
Precision: CNC ground finish (Ra ≤ 0.4μm)
Fatigue Strength: ≥ 800 MPa (validated by rotational bending tests)
