What kind of reducers are needed for wind power equipment? What are the well-known brands?

In wind power equipment, reducers are the key to ensuring efficient operation. Given the heavy loads and harsh working conditions of wind power equipment, EED Transmission offers customized new energy-specific reducer solutions, ensuring stable and reliable generation of every unit of clean electricity.

Wind Power Equipment: The "Power Foundation" Resisting Wind and Rain, Suitable for Three Core Systems

Wind power equipment is constantly exposed to harsh environments such as mountains, seas, and deserts, requiring resistance to strong winds, low temperatures, salt spray, and sand. Reducers must possess characteristics of "high load-bearing capacity, impact resistance, and long lifespan," suitable for three key systems of wind turbines:

Main Shaft Reducer: The "Power Transmission Core" of Wind Turbines

Application Scenarios
Connecting the wind wheel to the generator, it converts the low-speed, high-torque power captured by the wind wheel into the high-speed power required by the generator. It is a core transmission component for onshore 1.5-6MW and offshore 8-16MW wind turbines.

Core Functions
Bears instantaneous impact loads from the wind wheel (maximum impact torque can reach 2.5 times the rated value), preventing transmission interruptions;
Adapts to variable speed conditions (wind wheel speed 3-20r/min → output speed 1500-1800r/min), ensuring stable power generation efficiency;
Features a dual-seal structure to block sand and rain.

Key Parameters
Rated torque: 2000-15000N・m (customizable as needed);
Transmission efficiency: ≥96% (under rated conditions);
Lifespan: Designed for 20 years (matching the full lifecycle of the wind turbine);
Protection level: IP65/IP67 (IP68 for salt spray resistance in offshore models);
Temperature range: -40℃ to 60℃ (low-temperature models can withstand -50℃).

Wind Power-Specific Requirements

Meets GL, DNV, IEC, and other wind power industry certifications;
Offshore models must resist salt spray corrosion (salt spray test ≥1000h) and wave impact;
Supports remote condition monitoring (integrated temperature and vibration sensors) to reduce operation and maintenance costs.

Yaw Reducer: The "Direction Adjuster" of Wind Turbines

Application Scenarios
Drives the wind turbine nacelle to rotate around the tower, ensuring the wind wheel always faces the wind (yaw angle ±360°), improving wind energy capture efficiency, suitable for all onshore/offshore models.

Core Functions
Precisely controls yaw speed (0.1-0.5°/s) to prevent nacelle swaying;
Features braking and self-locking functions to prevent nacelle drift under strong winds;
Adapts to frequent start-stop conditions (10-20 yaw adjustments per day on average).

Key Parameters
Output torque: 500-5000N・m;
Positioning accuracy: ±0.5°;
Start-stop lifespan: ≥1 million cycles;
Protection level: IP65.

Pitch Reducer: The "Power Regulator" of Wind Turbines

Application Scenarios
Drives the blades to rotate around their own axes (pitch angle 0-90°), feathering for load relief at high wind speeds and pitching for power augmentation at low wind speeds. It is the "safety protection core" of wind turbines.

Core Functions
Quickly responds to pitch commands (emergency feathering time ≤10s) to ensure turbine safety;
Stably outputs torque at low speeds to prevent blade vibration;
Adapts to different models with blade weights ranging from 10-50 tons.

Key Parameters
Rated torque: 800-8000N・m;
Pitch angle accuracy: ±0.1°;
Can complete more than 3 pitch adjustments under emergency power supply;
Temperature range: -40℃ to 70℃.
