Improvement of Gear Unit Load and Noise Reduction by Optimal Design of Tooth Surface Using Principal Component Analysis

Abstract

Gear unit must be improved load capability and reduced its vibration and noise. In the conventional tooth surface modification design method, it was difficult to simultaneously improve the load capability and reduce vibration and noise. In this study, we made this possible by applying a shape representation method using principal component analysis to tooth surface modification design. This report describes an overview of the method and the results of the effectiveness verification by test.
