It is essential to have two coupled gears of different sizes on the intermediate layshaft. If three gears were used the overall ratio would be simply that between the first and final gears the intermediate gear would only act as an idler gear: it would reverse the direction of rotation but not change the ratio.
The input gear in this gear train has 13 teeth and the idler gear has 21 teeth. Considering only these gears the gear ratio between the idler and the input gear can be calculated as if the idler gear was the output gear. Therefore the gear ratio
A double reduction gear comprises two pairs of gears as single reductions in series. 3 In the diagram the red and blue gears give the first stage of reduction and the orange and green gears give the second stage of reduction. The total reduction is the product of the first stage of reduction and the second stage of reduction.
