Description

42CrMo Free Forged Planetary Gear Shaft for Heavy-Duty Transmission Systems. Our 42CrMo free forged planetary gear shafts are designed for high-performance transmission systems operating under heavy loads, high torque, and continuous duty cycles. Manufactured through precision open-die forging and heat treatment, these shafts offer superior strength, toughness, and dimensional stability essential for critical powertrain components.

Key Features:

  • Material: Made from premium 42CrMo alloy steel, offering high tensile strength, excellent hardenability, and outstanding fatigue resistance.

  • Forging Process: Open-die free forging ensures directional grain flow, minimizing internal defects and enhancing mechanical performance.

  • Heat Treatment: Quenched and tempered to achieve optimal hardness, toughness, and wear resistance; stress-relief annealing available for added dimensional control.

  • Machinability: Rough or semi-finished machining available for gear spline, shaft ends, and bearing interfaces to meet specific design requirements.

  • Forging Ratio: ≥ 3.0 — critical for high fatigue strength in rotating applications.

Applications:

  • Planetary gear systems in wind turbine gearboxes

  • Heavy-duty transmission systems in mining, construction, and industrial equipment

  • Drive components in off-highway vehicles and metallurgical machinery


Item Details
Product Name 42CrMo Free Forged Planetary Gear Shaft for Heavy-Duty Transmission Systems
Material Grades - Alloy steel: 42CrMo - Provides high tensile strength, good hardenability, and excellent fatigue resistance under continuous high-load operation
Forging Equipment - Hydraulic hammers: 5T / 8T / 12T - 3600T open-die forging press for long or stepped shaft forgings - Capable of forming precise shaft profiles including stepped ends, flanges, splines, and keyways
Manufacturing Process Hot Forging → Heat Treatment (Quenching + Tempering / Normalizing) → Ultrasonic Testing → Rough / Semi-Finish Machining → Final Dimensional Inspection
Forging Ratio ≥ 3.0 — Enhances grain flow alignment along shaft axis for increased impact resistance, torsional strength, and long-term durability
Applications - Planetary gear shafts in wind turbine main gearboxes - Drive shafts for mining, construction, and industrial machinery - Transmission shafts in metallurgical and heavy transport systems
Heat Treatment Options - Quenched + Tempered for high strength and fatigue resistance in dynamic torque transmission - Normalizing for improved grain refinement and dimensional control - Optional stress relief to reduce residual stresses before final machining
Testing & Inspection - Chemical: Composition analysis via spectrometer - Mechanical: Tensile strength, yield strength, hardness, and Charpy impact tests (longitudinal & transverse) - Ultrasonic Testing (UT): 100% internal flaw detection - Dimensional: Runout, straightness, diameter tolerance, and surface roughness control
Value-Added Services - Pre-machining of splines, gear ends, keyways, and journals - Surface finish customization and anti-corrosion protection - Export packaging for long-distance shipment - Full material traceability: heat number, batch number, and certified mechanical & NDT reports
