A study on optimal determination of partial transmission ratios of helical gearboxes with second-step double gear-sets

In this paper, a study on the applications of the optimization and regressions techniques for optimal calculations of partial ratios of helical gearboxes with second-step double fear-sets for minimal cross section dimension is introduced. From the condition of the moment equilibrium of a mechanic syystem including three gear units and their regular resistance condition, models for calculation of the partial ratios of helical gearboxes with second-step double gear-sets were given. Especially, by regression analysis, explicit models for calculations of the partial ratios are introduced. These models allow determining the partial ratios accurately and simply.
