To certify the effect of the dynamic load on the oil-film-formation under partial elastohy-drodynamic condition in spur gears, the cross-correlation function R_<xy>(τ) was measured between the insulating voltage of oil-film and the vibration-acceleration in circumferential direction. The measured cross-correlation functions show clearly that the breakdown of oil-film is apt to occur at the maximum of vibration-acceleration. Under a light tangential load, the coefficients of correlations R (O) were minus and their absolute values were large owing to large fluctuation of dynamic load, compared with the case of a heavy tangential load. In the case of a pair of hobbed gears, R_<xy>(0) had a higher absolute value in comparison with the case of ground gears. However, after the oil-film was almost completely formed by running-in, or when some pittings occurred at gear teeth, the crosscorrelation functions were distorted and the absolute values of R_<xy>(0) became small.
