Product Description

Wind Turbine Gearbox Second-Stage Sun Gear | Efficient Transmission Core for Intermediate Speed Stage

The second-stage sun gear plays a pivotal role in connecting the preceding and following stages of the drive train. After the initial speed reduction, it transmits power at higher rotational speeds. Compared to the first-stage sun gear, it features a more compact design but demands extremely high dynamic balance and machining accuracy. We utilize the same high-quality alloy steel (e.g., 18CrNiMo7-6) and employ targeted heat treatment processes (such as hydrogen removal treatment) to effectively prevent the formation of flake cracks, ensuring long-term operational reliability under high-speed conditions.

Dedicated Manufacturing & Inspection Flow:

Incoming Material Inspection
Blank Cutting
ring rolling
Post-forging Inspection
Heat Treatment (Hydrogen Removal, Normalizing + Tempering)
Heat Treatment Inspection
Physical & Chemical Testing
Rough Turning
Inspection (Ultrasonic Testing, Spectroscopic Analysis, Hardness Testing)
Marking, Cleaning & Packaging for Warehousing or shipment

Core Parameters:
