Product Description

Wind Turbine Gearbox Sun Gear Forging| Precision Forged and Machined Core Transmission Component

The sun gear serves as the "heart" of the planetary drive system in a wind turbine gearbox. As the central driving gear, it is engineered for efficient and reliable transmission of extreme torque. Our wind turbine gearbox sun gear blanks are manufactured from premium alloy steel (e.g., 18CrNiMo7-6) through Precision Forging and machining, delivering exceptional bending fatigue strength and contact fatigue strength.

We specialize in producing large sun gear blanks covering a size range up to ≤5 meters in diameter and 100 kg to 9 metric tons in weight. Whether you require a first-stage sun gear for low-speed, high-torque applications, or a second-stage sun gear for high-speed transmission, we can supply high-quality Forged Blanks after preliminary heat treatment. All products are manufactured to the most stringent quality standards. By integrating optimized heat treatment processes (such as normalizing + tempering, quenching and tempering) and comprehensive inspection (Ultrasonic Testing, Spectroscopic Analysis), we ensure every sun gear meets the demands of heavy-duty, long-life operation—both internally and externally.
