Third-Stage Planet Shaft – The Precision Core for High-Speed Operation
Located at the end of the transmission chain, the tertiary planet shaft operates at the highest speeds, placing extremely demanding requirements on dynamic balance accuracy, wear resistance, and resistance to micropitting. This product is designed with a focus on achieving smooth operation and long service life under high-speed conditions, directly impacting output speed stability and noise control.
The tertiary planet shaft functions in a high-speed operating environment, emphasizing dynamic balance and fatigue strength. We have optimized its process route: after
forging and normalizing + tempering
heat treatment, material allowance is controlled via precision rough turning. Spectrometric testing is performed to ensure precise material composition, combined with Ultrasonic Testing to verify internal quality. This efficient and precise process is particularly suited for applications with stringent demands on speed and precision, such as marine propulsion and high-speed compressors.
