The third stage
planetary gear operates at the high-speed end of the transmission chain, serving as the final critical link in achieving the generator's rated speed. It prioritizes dynamic balance precision, low noise, and fatigue resistance under high-speed conditions. Our 3rd stage planetary gear
forging blanks undergo specialized
heat treatment to refine the grain structure, ensuring dimensional stability and low wear rates during high-speed operation, thereby delivering smooth power transmission directly to the generator.
Core Production Process and Quality Flow for Planetary Gears
Our mature and stable single heat treatment process route achieves optimal balance between performance, efficiency, and cost. This route includes a complete full-process quality inspection system, ensuring reliability and consistency of every planetary gear.
Recommended Applications: This process is ideal for 2nd stage planetary gear blanks and 3rd stage planetary gear blanks in wind turbine gearboxes and various
heavy machinery applications, offering balanced performance and rapid delivery.
