know this is an old thread.
But I want to emphasize, that if you substract involute gear from a cylinder you DON'T get valid involute inner teeth.
I did it yesterday, but it was too quick thinkging. The result could be acceptable for some info graphics, but certainly not e.g. for 3D printing a real gear.
I think, that at this moment, the only way is to take an engineering handbook and draw a precise sketch to base the gear with inner teeth on...
Complete Fake news, you do not know anything about machining pinion, look at my answer 2 post above
Well, I'm not an expert on gears, true
. Perhaps I made a mistake, but please provide a reference
. It would be for benefit of all other visitors of this thread.
Just to make it clear, I undertand you're saying that if you make a gear of required teeth count, with given modulus and given angle of engagement (aka pressure line angle, let's say 20°) and create an inverse shape, you'll get a valid outer ring for any gear with the same given modulus and angle of engagement. Right?
