i Ratio

Total ratio in general

iges = i1 · i2 · i3

         iges
i1 =
        i2 · i3

Total ratio from numbers of teeth, diameters

           z2·z4·z6
iges =
           z1·z3·z5

           d2·d4·d6
iges =
           d1·d3·d5

Total ratio from torques

          ME
iges =
          MA

ME = MA · iges

         ME
MA =
          iges

Total ratio from speeds

          nA
iges =
          nE

nA = nE·iges

           nA
nE =
            iges
