Scuffing is a particularly severe form of gear tooth surface damage in which seizure or welding together of areas of tooth surfaces occurs, due to absence or breakdown of a lubricant between the contacting tooth flanks of mating gears. High surface temperatures caused by high surface pressures and high sliding velocities can initiate the breakdown of lubricant films. The T-EHD theory to the calculation of-gear tooth load, tooth oil film thickness and Blok's flash temperature criterion, based on contact temperatures which vary along the whole contact, as a joint scuffing resistance criteria, are presented.
