Abstract (EN): The analysis of experimental and theoretical results, from constant temperature scuffing tests with FZG type A gears lubricated with base oils, show a good agreement between the scuffing loads and the scuffing lubricant film thickness, meaning that a close relation exists between scuffing failure and lubricant film breakdown, fora base oil tested in the FZG rig. This relation is exploited, associating the classic PV scuffing criteria with the lubricant film thickness in scuffing conditions. Correlating experimental and theoretical results, a more general PV scuffing criteria is developed which depends on the lubricant properties and lubricant temperature. The application of the new scuffing criteria to FZG-A/8.6/90 standard tests predicted the corresponding scuffing loads with excellent accuracy. (C) 1998 Elsevier Science S.A.
