internal denture

[PaoloR1]

Hi.
I should create a gear with internal teeth. example: a ring that has the toothing on the inside.

I can't find a way with inventor. Can anyone help me?

Thank you and hello.

use the same tool that makes external gears.
to understand us in the environment together, where you find the various tools for calculating trees, sticks etc.
I have the old version 2013, I don't know what you have.

Thanks for the answer. I have version 2023. for now I made them with the Boolean subtraction. a bit slender but it works.

But if you use the inventor tool, you can choose the internal toothing.
logically the tooth profile is schematized, but there is also the possibility to extract the profile of a tooth in exact dxf.
attention, being an internal detachment, to pay attention to any interference, both for the construction of the teeth and for the engraving.

Can I ask you how you got the "mask" part and if you need it just like indexing or have to rotate something? in this case the profile must be evolving and not approximate. Sorry about curiosity! :

the male part I got it from the usual way of inventor to realize the gears to straight teeth. together-design etc.etc.

The subtraction profile is generally incorrect if you need a real profile....they look like....but if you print it in 3d wouldn't work.

I'm not questioning. but if I go to check the teething parameters, it corresponds to the table that you usually provide to the gear manufacturer. for now I just realized this 3d to be inserted in the axieme.

If it is only for "exthetical" purposes it goes more than well, logically as you will know, in the internal toothing you have to pay particular attention to the interferences that may be in the process of toothing and/or ingracing.
