Bevel angles not working

[Timothy Moulton]

Nutating is probably more accurate. Something like:

or

On a completely different note, would it be possible to output 3D data for only a pie slice that encompasses one tooth's worth of each gear? With the bevel and helical gears, the surface count climbs tremendously and solidworks has trouble importing them without exhausting its memory. I am sure this is poor programming in SW, but importing a slice and patterning it would be much faster.

Thanks!

Hi Tim:

  Thx for the treatise on nutating gears. For the life of me I cant figure a why on those. I see how they work,
basically the same as epicyclidal gear reduction, bot seem very similar with the nutatin gear having the disadvantage
of being more complex... Ill keep them in mind for future work.

  I cant as yet put out such a slice, but I will try in near future to put the gear out in a stp type of format so that programs
such as solidworks dont choke. Im very very close to the stage of attempting that. Within a few weeks a new version
of GT will be released as a sanity check aginst hardware out there vs the new code for speed and workability. Then Ill be
experimenting with new output formats for CAD users .

Thx

Art,

No problem and thank you for the continued replies. Nutating gears do create a lot more headaches with the shaft angles and such, but there are possibilities for CVTs and other functionality that I need for a project that are more difficult with other types of gearing. It is just a concept at this point. There is a PSU thesis out there somewhere that covers some neat CVT designs for helicopters and it is pretty cool stuff.

Thanks for the update on the exporting. I look forward to the additional capabilities.
