Abstract

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, Ahead of Print.
Based on the potential energy method (PEM) and elastohydrodynamic lubrication (EHL) theory, this paper proposes an approximate solution for the time-varying meshing stiffness (TVMS) of straight bevel gears that accounts for the actual tooth cross-section ...
