On the analytical definition of profile modifications minimising transmission error variations in narrow-faced spur helical gears

摘要

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. (C) 2015 Elsevier Ltd. All rights reserved.
