This paper addresses the definition of robust profile modifications in spur and helical gears. An original methodology is introduced which relies on closed-form analytical results on transmission errors combined with a Gradient Descent algorithm and a Gauss Quadrature-based full factorial method.
The results compare very well with those delivered by using classic Monte-Carlo simulations with a considerable gain in computational time. The influence of the probability distribution law for the design parameters (depth and extent of modification) is analysed along with the contribution of gear quality grade and load variation. Some optimum robust linear relief are presented which minimise transmission error fluctuations even in the presence of significant geometrical tolerances over a broad range of loads.
