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.
