ABSTRACT

This paper explains the formation of transmission noise and the basic cause being the tooth mesh excitation of gears. For detecting the excitation, metrological and functional methods are presented. The paper shows mathematical principles describing the tooth mesh. Beside physical properties, psychoacoustic metrics rating the hearing experience are introduced. Methods for influencing the tooth mesh and the derived rating are presented in the field of macro geometric design and flank form modifications as well as flank surface modulation.
