High-Torque Carbon Steel Input Shaft Forgings for Power Transmission Systems
High-Torque Carbon Steel Input Shaft Forgings are core drivetrain components engineered to transmit initial mechanical power in industrial systems. Manufactured from medium-carbon steel (e.g., 1045, C45) via precision open-die forging, these shafts deliver exceptional torsional strength and fatigue resistance for high-load startup conditions.
Optimized Torsional Rigidity
Directional grain flow aligns with shaft axis, maximizing torque capacity.
Superior Impact Absorption
Withstands sudden load spikes during equipment startup.
Controlled Machining Allowance
Near-net shape
Uniform Hardness Profile
Heat treatment ensures consistent properties through cross-sections
| Industry | Implementation |
|---|---|
| Industrial Gearboxes | Primary power input shafts |
| Heavy Conveyors | Drive head input shafts |
| Cement Kilns | Main reducer input drives |
| Mining Crushers | Crusher motor connection shafts |
| Wind Turbines | Gearbox input stages |

| Product Name | High-Torque Carbon Steel Input Shaft Forgings for Power Transmission Systems |
| Material Grades | carbon steels engineered for structural strength - Customized compositions for high-load power input applications |
| Forging Equipment | - Hydraulic Presses: 5T, 8T, 12T - Capable of producing large-diameter shaft forgings with directional grain flow |
| Manufacturing Process | Raw Material Inspection → Preheating → Open Die Forging → Heat Treatment → Rough Machining → Non-Destructive Testing → Final Machining (if required) → Dimensional Inspection → Packaging |
| Forging Ratio | ≥ 3.0 — Ensures enhanced internal density and fatigue resistance for high-stress applications |
| Applications | - Input shafts for industrial gearboxes and power drives - Drive shafts for heavy-duty rotating machinery - Transmission shafts for compressors, crushers, and hydraulic systems |
| Delivery Conditions | - Delivered in heat-treated condition - Optional: As-forged, stress-relieved, or semi-machined states per requirements |
| Testing & Inspection | - Chemical Analysis (Optical Spectrometry) - Mechanical Testing: Tensile, Hardness - Non-Destructive Testing: Ultrasonic Testing (UT), Magnetic Particle Testing (MT) - Dimensional inspection |
The steel forgings production flow:
raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
