Change Gear Finder for Gear Hobbing (With Differential)

This Change Gear Finder software calculates the possible change gears for a hobbing machine equipped with differential.

If a Gear Hobbing machine is equipped with a differential, the LEAD GEARS are computed in order to obtain the required helix angle. This program has been developed to calculate the Lead Gears for such Gear Gobbing Machine. 

However, the instructions of the hobbing machine manufacturers should be followed in computing the Laed Gears, because the ratio formula is affected by the location of the differential gears.

Accordingly, this program can also be modified and best Lead Gears can be found to minimize the errors in Helix Angle and Lead.
