Abstract The paper presents how the “Dynamic Quenching” and “Reversing gas flow” processes are successfully applied on internal ring gears and planetary gears for a 6-speed automatic transmission. The specific challenge was to reduce distortion in such a way that subsequent machining operations are entirely eliminated. As a result of extensive development in the quenching process, it was possible to meet the design metrological requirements. The internal ring gears have been in continuous production since 2006. By utilizing the special CFC fixtures and quench methodology of “Dynamic Quenching,” the customer was able to achieve the design intent, while eliminating all machining operations of the ring gears following LPC/HPGQ. Subsequent testing and monitoring over a 2-year period progressively demonstrated that conformance. Therefore, quality inspection was reduced accordingly.
