Internal Gears Modeling in Inventor

[Anonymous]

Greetings folks... Inventor Pro 2017 64 bit ...I am designing internal gears (Gear Coupling) and I am facing problem with this task, the problem is with the outer gear (Flange) when I select INTERNAL option every thing goes messy and most of the fields get red color in GEAR DESIGN menu... any help will be appreciated.. Attached you will find screen capture of what I am doing and mechanical drawings of the required components. Thanks.

Hi, try selecting "number of teeth" below (You should have selected at the beginning in design guide -> center distance )

then select "Feature" to perform the feature on the component you created.
Then check "Calculate" -> and then "OK" (you should have selected the cylindrical face of the part and the front plane of the tooth) Then advance in the boxes until you accept accept you should be able to perform the gear.

I hope this helps. regards

Can you post ALL the files that you have so far?? SO that we can either experiment or explore different possible solutions

Hi Sergio... Thanks for your efforts, it solved the problem, but what are the guide lines that made you select No. of teeth in the bottom of menu and center distance in Design guide field?.. is it a trail and error or there is something I missed?.. another question: why I can't make the couple of gears in one design menu? i.e. gear 1 and gear 2 in one menu so I guarantee full match ? you see when I select internal in the beginning I can not enter the tooth no. of the second gear which is 62 correctly .. it forces me to get it's own no. some thing like 30 which is wrong.. there also a red note saying: Design: tool tip is truncated.. what's wrong?

Finally.. I appreciate your help.. you made my day..

Thanks.
