In order to develop a better method of predicting gear noise of automotive power transmission as a function of gear accuracy, the correlation between the amplitude of the tooth mesh frequency component of measured noise and that of the simulated single flank rolling test of gears using the measured form accuracy of the tooth flank was investigated. Experimental and simulated results show, when the worst composite error surface of meshing tooth flanks is chosen as representative among many different composite error surfaces for possible combinations of meshing tooth pairs and the simulation is worked out under the hypotheses, that this worst composite error surface exists at every meshing of teeth, a very good correlation between simulated results of the single flank rolling test of the pair of gears and measured noise level of power transmission can be obtained. This result indicates that the development of the gear production method to minimize the scattering of deviation of tooth flank accuracy at each tooth of a gear is more effective in producing noiseless power transmission than in improving the average quality of tooth flank accuracy of gears.
