How does it work? I ve got 2 helical gears mounted in 90degrees angle.
On gear got od 31.1mm 18 teeth, helical angel 50, (lead 104.79mm)
other gear got od 40.7mm 18 teeth, helical angel 40 (lead 97.49mm)
I know that helical angel 40+50 = 90 so that prob why they work togheter, but how do they get the profile of the tooth, they looks like the same on booth gears and the got the same amount of theeth, normaly a bigger gear would have the same modul but more theeth to match.
Does anyone know any thing about this?
I did cut my gears both in 45 degrees angel, but I did have to use 18 theeth and 22 on the other to match the gears. But I would really want to cut them so I will get 18 theeth on both gears as the original parts have.
