High-Performance Forged Gears for Wind Energy Applications
Our forged gears are widely used in wind power gearbox systems, especially in high-load planetary and helical gear stages. 42CrMo4 and 40Cr alloy steels are selected for their superior mechanical performance after quenching and tempering treatment, offering:

High tensile and yield strength

Excellent impact toughness

Superior wear and fatigue resistance

Enhanced hardenability and stability

These properties make our gears particularly suitable for offshore and onshore wind turbines, where components must withstand fluctuating loads, temperature variations, and long-term vibration.

 

Key Features:

  • Material: Premium 4140 / 42CrMo4 alloy steel for optimal mechanical properties

  • Process: Free forging or die forging with strict metallurgical controls

  • Applications: Wind turbine gearboxes, port cranes, heavy-duty industrial transmissions

  • Heat Treatment: Normalizing, quenching, and tempering for maximum durability

  • Customization: Sizes and specifications tailored to your exact needs

  • Standards: ISO 9001, ISO 14001, ISO 45001 certified manufacturing process

Typical Applications:
Used as critical components in industrial gearboxes for:

  • Steel mills

  • Power plants

  • Cement equipment

  • Mining conveyors

  • Heavy-duty reducers and mechanical dr

Advantages:

  • Customized according to customer drawings or technical requirements

  • Optimized geometry for smooth torque transmission and minimal wear

  • Stable performance in high-load, high-vibration industrial environments

  • Competitive lead time and reliable after-sales support

Process flow: 

raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
