This is a gearbox calculator where you enter your gears and it gives you the ratio in addition to all information needed to CAD a transmission
I used JVN's design calculator all the time, but there were only a few things that I used from it, and there was always some other information that I would have liked. So I wrote this .NET 2.0 project.

This is the Gearbox Calculator Program I wrote in order to make my life as a designer much easier. All you have to do is enter the gear teeth and the wheel size, and it will output the Ratio, The FPS at 81% efficiency, The center distance between both sets of gears with an additional .002 inches for clearance. It also has some stock information including the OD of the CIM, how big all the screw holes are, and then some information if you want to CAD the holes for the AM encoder mount. In addition if using the 2 speed mode it will tell you if the 2 sets of shifting gears are the same center distance.
I am releasing this to the community in order to help as many teams as possible. If anybody has any suggestions, feel free to PM me or post them here.

I just got to playing with this. This is really a fantastic tool, and I'll keep it handy for future gearbox designs. Thanks for sharing it with CD.
