i hv made many reduction systems and never consider to show inovlute profile to worm gears/ spur gears cause i didnt wanted to give extra time to make those patterns and it may also decrease mobilty of model.. now i wish to know how to do it? if anyone knows how to make a perfect involute profile for worm wheel to match worm's thread plz post here i'm also looking for bevel....
Thanx and Regards

It sounds extremely difficult.
I've modelled true involute spur gears, using an equation curve, but I haven't yet found a way to model an true helical gear, let alone a concave worm wheel.
Check the following link
I have tried to to make a rough model(without proper dimensions)
I dont have a proper dimension of gears
If you wish I can upload the model(for reference)
This is the origianl gear from the link (with some assumed dim)I have provided you earlier
(You can check this for your reference also)
Richard, to my knowledge both the worm and ring gear need to have an involute toothform or you wouldn't even be able to assemble them. And, from what I see, there is no helical lead on Dalbeers ring gear, and there should be.
