Abstract: After discussing the definitions and interrelations of several English terms on scuffing, this paper puts forward the concept of initial scuffing (scratching) which is considered the precursor of scuffing. It is suggested that the terms, characteristics and cause of the damage on gear tooth in the criterion of GB3481-83 should be modified. Based on the viewpoint of systems analysis, the influential factores of the gear tribology properties are concluded as circumstance, working conditiones, material and lubrication. The intent of these factores are explained. Considering the time-variability of the tribology system, the time-variable factores are also discussed. From the discussion above, the mechanism of gear scuffing is systematically and time-variably analysed.
