Unfortunately, in this case, that is analagous to saying to find another way to design a Hoberman Sphere. :biggrin:
The gears are primary to what this invention is all about.
Luckily I am onto a lead through a friend of a friend who has some rather sophisticated gear design software...
Unfortunately that is the part I don't know how to do.
I have some postings up on other forums. Hopefully something will pan out. I found a gear designer who will do the design ($$$$). Ouch! Especially considering that I am doing this on my personal time and with my own money.
Here are a couple of drawings that will better describe the geometrical relationship of the two gears....

The angular dimension on the first drawing is 48 degrees...
I was able to download a gear designer LSP for AutoCAD which allowed me to do what you mentioned; designing a custom angle bevel with a straight spline. But that still leaves me with only meeting the 48 degree requirement. I still have the 12 degree requirement to meet as well...
I got hold of a copy of Machinery's Handbook which has a whole section on gears. After reading up a bit on gears, here is perhaps a better description of the gear set I am trying to come up with a design for.
Two identical mating helix gears which have a bevel angle 48 of degrees and a...
I am looking for some help designing a gear for an invention of mine. I know gear design basics, but this is a little beyond what I know. Any help would be greatly appreciated.
The needed gear (to be made from plastic) is part of a toy and will be under very little stress. For my...
It is a concentrated load at the end.
The beam doesn't have to be of a constant cross section, however there is nothing to be gained (except extra fabrication costs) by tapering it as the arm increases.
I'll set up the spreadsheet and start plugging in numbers.
I am working on a project where I have an I-Beam supporting a cantilevered load.
For ease of fabrication, I need change the cross section of this I-beam.
