The influence of dynamic load on scoring capacity was studied using gears having tooth profile errors on the recess sides. Scoring capacity in spur gears is more affected by specific sliding than by dynamic load and increases as specific sliding is descreased. In the mixed lubrication state, the scoring bulk temperature of the working tooth flank is barely influenced by dynamic load when the tip interference on the approach side is negligible, and it may be well estimated by the bulk temperature on the outer surface of the cylinder immediately before seizure in two-cylinder tests. In the calculation of the bulk temperature of the working tooth flank, it is essential to take account of dynamic load and tip interference as well as the heat transfer coefficient and friction coefficient.
