Product DescriptionTotem Custom Forged Alloy Steel Large Gear Shaft for Heavy Industrial ApplicationsThe Forged Alloy Steel Large Gear Shaft is engineered for extreme-duty industrial applications, utilizing premium 42CrMo4 alloy steel with vacuum degassing to eliminate inclusions. Precision-forged under 12,000-ton hydraulic presses, the shaft exhibits a refined grain flow structure, enhancing fatigue resistance by 35% compared to cast equivalents. Key features include ISO 1328 Class 6 gear teeth (ground to ±8μm profile tolerance), induction-hardened bearing journals (HRC 60-62), and custom keyway/spline options per DIN 5482/ISO 4156. The shaft undergoes triple nondestructive testing (UT/MT/RT) SpecificationApplications1.CNC machine tool spindle boxes2.aero-engine transmission shafts3.Industrial robot joint reducers4.NEV e-drive systemsKey ConfigurationsHigh-Precision Machining? Hard Turning + Grinding Compound Process CBN tool hard turning (HRC58-62) CNC grinding for journal surfaces (Ra≤0.4μm, coaxiality≤0.005mm) CBN (Ra≤0.4μm,≤0.005mm)? Gear Forming Technology Hobbing-Shaving-Honing (DIN Class 6 accuracy) CNC Gear Shaping CNC (Internal gears, AGMA Class 12 accuracy)Processing Workflow1.Forging Process: Formed using a 2000-ton hydraulic press for precision forging.Key Control: Ensures grain flow continuity and eliminates casting defects.2.Rough MachiningOperation: Turning with 2mm machining allowance for subsequent finishing.Purpose: Prepares the workpiece for heat treatment with uniform dimensions.3.Heat Treatment Quenching & Tempering Quenching: Heated to 850°C, then oil-cooled for high hardness.Tempering: Reheated to 550°C to enhance toughness and relieve stress.Carburizing Grinding Process SpecificationsMilling Process1.Pre-Grinding Preparation2.Rough Grinding3.Finish Grinding4.InspectionMilling of shaft partsThe milling of shaft parts requires high concentricity control.Shaft milling processThe shaft milling process includes slotting and grooving.Related product recommendationsCustom configurations available upon request.We have different specifications of oil forging presses,ring rolling machines,electric arc furnaces,thus we can provide variety of forging,casting and welding materials according to customer's requests.Large capacity, completed variety of quenching medium: oil,water,salt water,water based mixture.Company ProfileSHANGHAI TOTEM MACHINERY CO., LTD.Shanghai Totem Machinery Co., Ltd.
