Evaluation of engagement accuracy by dynamic transmission error of helical gears

Abstract

The paper presents an analytical and computer-aided procedure for the prediction of the dynamic transmission error of helical gear pairs by using variable mesh stiffness. An improved model of the mesh stiffness is developed by including specific meshing characteristics of helical gear pairs. The effects of addendum modification coefficients and face-width of gear pairs on the time varying mesh stiffness are investigated. A comparative study has been performed to analyze the effect of the total contact ratio and its components on the dynamic transmission error of helical gear pairs. © Springer Science+Business Media B.V. 2010.
