An Alternative Approach to the Definition of Profile Modifications in High-Contact-Ratio Spur Gears
Résumé
Two original analytical formulations are presented which explicitly give the depths and extents of
symmetric profile modifications minimising the fluctuations of quasi-static transmission error in
narrow-faced spur and helical gears. Numerous comparisons with quasi-static and dynamic
simulation results are presented which prove that the proposed theory is sound. The proposed
formulae can therefore help define adapted reliefs in terms of transmission error and dynamic
tooth loading with minimum effort.
