| Product Name | 20CrMnTi Drive Shaft Spindle High Speed Shaft Low Speed Shaft Free Forging |
| Material Grades | - Case-hardening steel: 20CrMnTi - Excellent wear resistance, core toughness, and dimensional stability after carburizing and quenching - Optimized for spline shafts under rotational and axial stress in solar tracking systems |
| Forging Equipment | - Hydraulic hammers: 3T / 5T / 8T - Open-die forging press with axial forming capabilities - Supports spline shaft forgings with precise grain orientation and improved fiber continuity |
| Manufacturing Process | Hot Forging → Carburizing / Q+T Heat Treatment → Spline Pre-Machining → Ultrasonic & Dimensional Inspection → Optional Surface Treatment |
| Forging Ratio | ≥ 3.0 — Enhances fatigue strength and wear resistance by aligning grain flow along spline direction and shaft axis |
| Applications | - Spline shafts for single-axis and dual-axis solar tracker actuators - Rotary drive links and transmission couplings - Ideal for outdoor PV plants with dynamic load adjustments |
| Heat Treatment Options | Quenched + Tempered for general structural use - Optional stress relief to enhance dimensional stability before finish machining |
| Testing & Inspection | - Chemical: Spectrometer-controlled material composition validation - Mechanical: Hardness (surface/core), tensile, yield, impact testing - Ultrasonic (UT): Focused inspection of spline root and shaft body - Dimensional: Spline profile accuracy, runout, diameter, concentricity |
| Value-Added Services | - Pre-machining of spline teeth, journal ends, keyways, shoulders - Surface coatings: phosphating, zinc plating, or anti-rust oil - Custom shaft lengths, bore features, and end configurations - Steel banding, end cap protection, heat number traceability |
