how to create a gear that drives a ring

no_name433

Hi,

Trying to create a gear that is driving an outer ring.

In the picture you can see the gear I created in blue near the "22" and "23" numbers.
That gear should rotate that numbered ring.

I cearted the small gear using the "spur gear" script but I am strugeling with the gear on the inner side of the numbered ring.

I'll aprisiate any help, direction, method you can offer that will enable me to do that.

Thanks

Hi, create a gear with the module and number of teeth you want for the inner sided gear and subtract it from a disk... or use this feature

Creating a gear and subtract it from the ring, although did creae a geared ring, did not make the ring and the small gear match.
The tooth of the small gear and the ring never matched and the gear got stuck.

I used you planetary gear addon you suggested and it did the trick.

Thanks !!!

Hi there! I hope you're having a lovely day! I just wanted to let you know that I've tested the tool and it's doing exactly what I described. You can see it in action here.

The outer gear ist made by the Planetary tool an the inner gear with the spur gear feature. Both have 30 teeth an a Module of 1mm. 0 Interfeerence and no play between these Parts.
