Abstract
An experiment has been conducted to examine the independent influences of rolling speed and sliding speed on the scuffing of hardened steel discs lubricated by a mineral oil. Both sliding speed and rolling speed have important effects on the scuffing conditions. There is a difference between scuffing conditions at low mean rolling speeds, 0.8 m s−1 or less, and those at higher rolling speeds, 1.6 m s−1 or above. Various criteria for scuffing have been examined. It is possible to define ranges of rolling and sliding speeds over which any one of three of these criteria, total contact temperature, film thickness and friction power intensity, is approximately constant. All these quantities show wide variations outside their respective ranges. Of these criteria, the friction power intensity has the widest range of application.Keywords
