HELP - Bevel Gear generate ?

[Anonymous]

Hello everyone.
As per the attached image, I'm trying to generate this pair of bevel gear through the Design Accelerator in Inventor, but I'm not getting a good result.
If possible, I ask everyone's help to try to model it, to know where I am making mistakes.
Thanks in advance for your help. Thank you.

Here is a screencast of the creation of your desired bevel gears.  The only thing I cannot get the gears to do is mesh.  The bevel gear configuration is:

It is really interesting, the gear you are showing in you screen capture only has 16 teeth where you asked for 11 and 18 teeth, mistake?  See screencast for my process.  If you can use the assembly, Inventor 2019.2, just let me know.

By the way, the schematic drawing shows the gear teeth machined off flush with the face on one gear.  If that is what you want, simply open up the gear and use the Split tool to trim off the teeth as per your schematic.  Here is a section view with the gear trimmed off.  My shafts are just there for my placement reference.

Look at the problems I found:

Dear Mr. Jhackney
The photo of the pinion was merely illustrative. Excuse me.
In reality the pinion has 11 teeth.

At the end of my last post, I mentioned and showed you how to cut off the gear teeth, on the one, to match your schematic.  About the lousy engagement.  The Design Accelerator is noted for modeling inaccurate gears, at least in the model.  When you model spur gears, if you right click on the gears in the assembly, you can export a "true" tooth form for each.  I do not see this same feature for bevel gears.

As far as the "Face Width" number, I do not know how this number relates to bevel gears, so I will not comment.

No problem, I was just checking if you were calculating the correct number of teeth that is why I commented.

I have the same problem (the "export tooth profile" option is gone).  I have exported the true tooth shape in previous versions of Inventor but either that option is gone, or I don't remember how to do it.

If anyone knows how to do this in Inventor 2020, please let me know.

You must right click on the Design Accelerator node in the browser (see special symbol).

That option isn't present for bevel gears.  See the attached screenshot.

Not surprising to me as it only exports one sketch and bevel gear is tapered.

You might experiment creating a spur gear and then taper the extrusion.

I don't know if this will result in correct tooth form.
