seamless screw dimensioning

[Zdravco]

Hello everyone, I am new to this forum. I have written because I believe that those who have more experience than I can help me with the following question.

I have to design a transmission system with ratio 1:32, which for reasons of bulk and functionality I am forced to divide 16x2. for the ratio 1:16 I have to use a worm gear without end-wheel toothed helical, but I cannot find the right way to dimensional the perpetual screw (conductor). What data do I take as starting points? I have documented myself properly on the engineer's manual, among other things very well done, but in this topic it loses effect and makes confusion.

Thank you very much.

I imagine your transmission system is continuously and not with high intermittent ratio. you will always turn around and it is not a lifting pencil.

First look on the forum the design of an endless screw that you will find my discussion about the legislation to follow.
if you use kisssoft you will have the appropriate tools to make sizing and verification.
on the site khk gears there are several pdf explaining geometry, forces and dimensioning to standard.

on this forum you will find several indications about it.

Are you sure you don't agree to trade two gearboxes and combine them?
