Gear Lab Pro app for iPhone and iPad

These calculators have been developed to help in the Setting up, Production and Checking of the gears like the ones available via the Ultrascale web site. Three of the main types of gears are covered, these are Worm gears, Helical gears, and Spur gears. The flow of the app has been setup in such a way as to allow for the calculators to be used on a individual basis, using the minimal of information to output the basic data required, or as a complete process flow from start to finish. For example , starting at the worm then creating a matching worm wheel and then to output the base tangent data to allow the gear to be checked.

This app extends these calculators to include the setting up of a non-differential Hobbing machine. In our case a Pfauter RS00. However, there is no reason these calculators could not be used with other hobbing machines that uses the same basic setup. The hobbing machine calculators are a three stage process.

First, data is input about the Hobbing Machine, Hob and Gear to be Cut. This stage also outputs the hob head position and hob setting angle.

Second, the Index change gears are calculated using data from the first stage.

Third, the Feed change gears are calculated using data from both the first and second stages.

The setup data from all three stages can then be saved and viewed later from within the app.
