Hello i am having trouble figuring out the proper profile to use for the worm and the gear. I need to model it in solidworks and everything i am finding online is for spur gears. I need to get the worm and gear to mesh correctly so i can do some finite element analysis on it. I have calculated my pitch diameters for both and i have what i believe to be the correct addendum and dedendum dimensions for my worm gear. Can someone point me in the right direction? how does one get the proper involute for their teeth?
