The geometrical shape of each tooth flank of mass-produced gears usually varies and is not the same. This variation in the tooth flank shape greatly influences gear vibration and the whining noise of transmissions. The variation may be random or periodical around a gear. The latter type is often found in mass-produced gears such as shaved gears due to the influence of the previous shaving process. The main factors causing periodical variation in the previous process are thought to include gear shaft eccentricity and the inclination of the gear blank. This paper proposes a simulation method for calculating the variation in the tooth flank shape based on these factors. It also describes an improved method of analyzing helical gear transmission error that takes into account the tooth flank shape of every tooth of a gear pair. With these methods, we can accurately analyze the transmission error of a helical gear pair that has variation in each tooth flank shape, by measuring the eccentricity and inclination and without measuring the accuracy of every tooth surface.
