First-Stage Planet Shafts for Wind Turbine Gearbox

Primary Planet Shaft – A Solid Foundation for Heavy-Duty Torque As the core load-bearing component in the first-stage transmission of a wind turbine gearbox, the primary planetary shaft directly withstands the maximum torque and impact loads captured by the rotor. This product is specifically designed for extreme operating conditions characterized by ultra-low speed and high torque. Its core focus lies in providing unparalleled resistance to bending fatigue and impact toughness, ensuring zero deformation and fracture under heavy loads, thereby offering the most robust support for the entire drive train. The primary planet shaft directly bears the maximum loads and impacts from the planetary gears, demanding exceptionally high strength and durability. We have developed an enhanced manufacturing and inspection process for it: after basic forging and quenching & tempering heat treatment, it undergoes rough turning, followed by strict Ultrasonic Testing to eliminate internal defects, a…
