ABSTRACT
This paper presents a study on the optimum determination of partial
transmission ratios of a mechanical drive system using a V-belt and a helical
gearbox with second-step double gear-sets in order to get the minimum size of
the system. The chosen objective
function was the cross section dimension of the system. In the optimization
problem, the design equation for pitting resistance of a gear set was
investigated and equations on moment equilibrium condition of a mechanic system
including a V-belt and a helical gearbox with second-step double gear-sets and
their regular resistance condition were analysed. Based on the results of the study, effective formulas for calculation of
the partial ratios of the V-belt and a helical gearbox with second-step double
gear-sets were proposed. By using explicit models, the partial ratios can be determined
accurately and simply.
