High Strength P/M Gears for Vehicle Transmissions - Phase 2; Final rept. 16 Aug 2006-30 Jun 2008

摘要

This effort accomplished three major objectives. A production capable powder metal (P/M) gear ausform finishing machine was designed by a select machine tool builder (Kinefac Corporation of Worcester, CT). The integration of this machine on the production floor of a powder metal parts manufacturer (Keystone Powder Metal Company, St. Marys, PA), which included the automatic load/unload mechanism and other sub-systems, was defined. The final objective accomplished was the optimization of the ausform finishing process and the total P/M gear manufacturing process to achieve higher gear quality and lower cost, with the use of lower density P/M parts.
