Gear Tooth Geometry in NX
Gear Tooth Geometry in NX
(OP)
Has anyone dealt with drawing a gear in NX? something with correct involute and tooth geometry. If so what is the best way to go about that?
I have all the data just want to know what the best/most accurate way of drawing the tooth profile in the program would be.
I'm using NX 7.5
Thanks!

After yuo download the file, edit the file extension from .zipper to .zip and then extract the files.

Sometimes people rename exe or zip files because some servers don't allow you to upload them or the antivirus can complain about its content.

I like the Expression setup in your file but I am having issues with it creating the geometry without giving errors.
I can't change the major or minor diameters.
Any ideas?
I'm updating the following values:
INPUT_Gear_Thickness
INPUT_Major_Diameter
INPUT_Minor_Diameter
INPUT_Number_of_teeth
INPUT_Pitch_Diameter
INPUT_Pressure_Angle
INPUT_Tooth_Thickness
I start to receive the errors at the major diameter input.
Am I missing something here?
John, I'm having trouble opening your files in NX, I've extracted the zip files but can't seem to open them in the program. Any advice?
Thanks!

I read the manual ( NX 7.5 Manual) regarding the GC toolkits, there is nothing saying that we shouldn't use these tools.
Is there a reason ? I can see that the results aren't "fully featurized" but i assume that if one has the need, -why use something different ? Support issues ?

Tomas

Perhaps it would be better to say that you should use them "at your own risk" in that if anything fails or you discover that it's incompatible with something else that we've done in a more recent version of NX (for example, I haven't enabled the GC tools in NX 9.0 with the Ribbon UI), it's unlikely that we will be able to help you much.

I have not tried the tools you provided in your zip but i did play around with the CG stuff and being a "gear layman", the results look very good, whatever my opinion is worth.
( Btw , it's good that you read everything
