If you think about the mathematical calculation of such a problem, it looks quite complicated. It will take several days of work and several books on theoretical mechanics.
But you can do it easier. Make a 3d model of the gear you need with the help of specialized programs like GearTeq or GearTrax. Then just increase the distance between the gears in the model and measure the backlash.
I meant mathematically accurate calculation. This means that we will need to include here the involute formula for a specific module and number of teeth, as well as bring the movement of all points to the same coordinate system, and then calculate the angular value of the backlash. This is a good task for the theoretical mechanics exam.For 14.5* teeth, the tooth thickness is about 1.4 times the depth
I guess so. But it's absolutely useless for anything in the real world. There's no point in even drawing teeth on a print or wasting the time modelling them, the machine will make them correctly all by itself. There are ways to offset the path in wire edm; if you are doing the 'surfacing large spiral bevels" thing on a dmg then the software will do it, in any other method of cutting teeth I can't think of a single realworld purpose for any of that silliness.This is a good task for the theoretical mechanics exam.
