ABSTRACT
This paper introduces a new study on the optimum calculation of partial
transmission ratios of a mechanical drive system using a V-belt and a
three-step helical gearbox in order to get the minimum size of the system. The chosen objective
function was the cross section dimension of the system. In solving 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 three helical gear units and their regular
resistance condition were analysed. From the results of
the study, effective formulas for determination of
the partial ratios of the V-belt and three-step helical gearboxes were
introduced. As using explicit
models, the partial ratios can be determined accurately and simply.
