Auxiliary calculations of gearing

This workbook includes two auxiliary calculations to calculations of gearing.

Optimizing of parameters (dimensions, weight, volume) through distribution of the total transmission ratio "i" to individual pairs of gears with double reduction or triple reduction gearbox with spur gears.
Optimizing of the number of teeth of gears to achieve an exact total transmission ratio "i" with single, double and triple reduction transmissions (toothed wheels, toothed belts, chains)
