An Experimental and Analytical Comparison of the Noise Generated by Gears of Austempered Ductile Iron (ADI) and Steel Materials


Many have made claims concerning the relative noise performance of Austempered Ductile Iron (ADI) versus steel as a gearing material. Predictions based on measured tooth topographies of the transmission error and "sum of forces" gear noise metrics show that the iron gears should be slightly quieter than the steel gears at loads beneath the transmission error optimization "notch" torque and slightly louder above this torque. This paper presents results from a systematic experimental study to ascertain these differences.
