What is the proper way to specify quality of a face gear? AGMA 203.03 (withdrawn specification for face gear design) references AGMA 390.03 for quality. However AGMA 390.03 has been replaced by AGMA 2000-A88 and AGMA 390.03a, and further AGMA 390.03a has been replaced by AGMA 2009-B01 and AGMA...

I'm working on a design with a face gear of European origin which references an addendum coefficient and a dedendum coefficient. What happens to the face gear when these coefficients are less than 1.0 or greater than 1.0? Is there a resource that explains this in detail?

What version of NX will support the new ASME Y14.5-2009 GD&T standard? Are there any tips for NX5?

The tip diameter of this gear is 1.35 inches.

Thanks for the input everyone! These gears are through hardened 4340 steel, or through hardened 440C stainless depending upon where they are located. The final stage is shot peened. Any guidelines as to the chamfer size (minimal, down to the pitch diameter, down to the root diameter, larger...

What purpose would a chamfer on the edge of a spur gear serve (refer to red chamfer in attached picture)? It is not for (housing corner radii) clearance. The last guy liked chamfers, but I can't figure out why.

I have a situation similar to thread89-45878 except I have a metallic gearbox with fine pitch metallic gears along with an electronics package which is weaping oil which has separated from the grease. Operating temperatures are -40°C to +120°C, and speeds from 10,000rpm at the input to 100rpm...

I also compiled those two grip programs but they create non-parametric models and they are not for helical gears. I will check out your Excel to DXF link. I think we are getting close to having a parametric helical gear using a law curve to generate the involute tooth profile, and a helix...

What is the easiest way to model a helical gear in Unigraphics (NX3 or NX5)?

We use Unigraphics NX5, but received a number of Solid Edge V19 parts and assemblies. We can open the parts without difficulty. When we try to open the Solid Edge assembly files we get two error messages stating "The PLM XML document failed to load" and "Failed to import data from multi-CAD...

Anyone know when MMPDS-02 will be available (the advertised July 2005 date didn't happen)?

Is anyone familiar with the ESDU 00932? Would it have properties for "newer" aluminum alloys (example: 7136, 7249)? Are there any reasonbly priced options to get a copy (I was told $1600 purchase price plus $1000/yr for updates)?
