Heat-Treated Forged Alloy Disc As Mounting Base For Industrial Gearbox Housings.
| Item | Details |
|---|---|
| Material | Medium-carbon alloy steel (e.g., 4140, 4340) – Selected for superior strength-to-weight ratio, excellent impact toughness, and good machinability, ideal for withstanding high static and dynamic loads in gearbox mounting applications. |
| Heat Treatment | Quenching and Tempering (QT) / Normalizing and Tempering – Achieves a uniform tempered martensite or sorbite microstructure throughout the disc, providing balanced high strength, dimensional stability, and resistance to deformation under load. |
| Main Application | Specifically engineered as a rigid mounting interface for industrial gearbox housings – Serves as the critical foundation to ensure precise alignment, absorb operational vibrations, and distribute loads evenly into the supporting structure. |
| Production Process | Open-die forging → rough machining → full-section heat treatment → finish machining – Forging refines the grain flow; full-section heat treatment ensures consistent core properties; precision machining guarantees flatness and hole positioning. |
| Key Feature | High flatness and parallel tolerance on mounting surfaces – Critical for ensuring gearbox alignment, preventing housing distortion, and minimizing vibration and bearing wear during long-term operation. |
| Delivery State | Fully heat-treated and precision-machined finished component – Delivered with drilled and tapped bolt holes, precision-ground mounting faces, and protective coating, ready for direct assembly onto the foundation or frame. |
| Inspection Focus | Ultrasonic Testing (UT) for internal integrity, hardness mapping, dimensional accuracy of bolt patterns, and surface flatness measurement – Ensures the disc is free of internal defects and meets the strict geometric tolerances required for secure gearbox mounting. |
| Service Package | Tiangong provides integrated forging, heat treatment, machining, and comprehensive material certification – Offers full traceability from raw material to finished part, with documentation supporting gearbox OEM quality and safety standards. |
