High Precision Forged Gear For Wind Turbine Main Gearbox Drive System Components

High Precision Forged Gear for Wind Turbine Main Gearbox Drive System Components

Our high-precision forged gears are engineered specifically for wind turbine main gearbox drive systems, where reliability, torque stability, and long-term durability are crucial. Manufactured from premium alloy steels and processed through controlled forging, heat treatment, and precision machining, these gears deliver exceptional mechanical strength and outstanding load-carrying capability under continuous variable-speed operation.

Key Features

• High Strength & Fatigue Resistance: Forged with a high forging ratio to ensure uniform grain flow, improved toughness, and superior fatigue life in high-load wind turbine environments.

• Precision Machined Gear Profiles: CNC hobbing, shaping, and grinding guarantee tight tolerances and low noise levels, supporting efficient gearbox performance.

• Optimized Heat Treatment: Carburizing, quenching, and tempering processes enhance surface hardness while maintaining a tough, shock-resistant core.

• Enhanced Reliability in Harsh Conditions: Designed to withstand long-term exposure to high torque, vibration, and fluctuating wind loads.

Applications

• Main Gearbox High-Torque Drive Components in onshore and offshore wind turbines

• Speed-Increasing and Power-Transmission Modules across multi-stage gearbox assemblies

• High-load rotating systems used in wind energy equipment requiring durable and precision-forged gearing

Process Flow:

Initial raw material confirmation → organized unloading and safe handling → detailed dimensional and surface quality check → uniform preheating to forging temperature → precision forging operations → heat treatment to achieve required mechanical performance → continuous quality monitoring during processing → rough machining of forged parts → non-destructive testing to detect internal or external defects → final accuracy and quality inspection → corrosion-protected packing → dispatch to customer.

Frequently Asked Questions (FAQs) – Differentiated Version

1. What is the range of forgings you can produce?
Our production capability covers forged parts from around 100 kg up to 7,000 kg, suitable for both medium-sized assemblies and large, high-load industrial equipment.
