In this study, we investigated on the vibration of two elliptical gear pairs, which are a single elliptical gear and a double elliptical gear. The circumferential vibration acceleration, the torque variation, and the gear sound pressure level of two elliptical gear pairs and two circular gear pairs with the same number of teeth and the same center distance as the elliptical gear pairs were measured by the running test. Additionally, we developed a torsional vibration model of the testing machine with elliptical gears, and calculated the circumferential vibration acceleration of the test gears, and the torque variation of the test gear shaft. We considered on the vibration of elliptical gears by comparing the measured data with the calculated results.
