Low-Distortion Heat Treatment of Transmission Components
The article "Low-Distortion Heat Treatment of Transmission Components" appeared in the October 2011 issue of Gear Technology.
This paper presents how low pressure carburizing and high pressure gas quenching processes are successfully applied on internal ring gears for a six-speed automatic transmission. The specific challenge in the heat treat process was to reduce distortion in such a way that subsequent machining operations are entirely eliminated.
