The correlation between the oil supply conditions, such as oil jet velocity, oil-nozzle position and its direction, and the scoring resistance of spur gear pair has been studied. The influence of the oil supply conditions on the instantaneous behaviors of the lubricating oil supplied onto the tooth flanks were brought to light by stroboscopic photographs. The scoring resistance was greatly affected by the oil supply conditions and the reasons were clarified by considering the instantaneous behaviors of lubricating oil. In order to have high scoring resistance, oil must be supplied over the whole working flank.
