Improved Predicting Method of Gear Tooth Strain in Transmission

Abstract

In recent transmissions, enhanced fuel efficiency considerations call for further weight reduction without sacrificing reliability. This extends to the comprising parts in a transmission, where lighter designs that ensure the required gear strength are expected. This paper proposes the improved predicting method relying on CAE to predict a gear tooth strain accurately considering a gear tooth contact condition. In addition, the accuracy of this method is identified by the experimental result.
