2932 Vibration Characteristics of Elliptical Gears

Abstract

Elliptical gear is a mechanism which transmits a non-constant rotation and a power simultaneously. In this study, we investigated on the vibration and noise characteristics 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.
