If it's going to be employed as an "electric wall sculpture" (what else would I do with these?), it will need some type of retainer around it to keep it from working itself off of the planetary gears and I haven't figured that out quite yet. The outer ring is tricky in any case and I'm saving that idea for another project. I can't increase the sizes in diameter proportionately for engagement because then the gear cogs get bigger (wider) too and won't mesh up with the outer ring (which is actually called an "inner gear"):confused: lol When I set the planetary gears and the sun gear at the prescribed number of teeth (as I did with the ring gear), they (the gears themselves), were too small in diameter to engage, being off maybe 15-20%. What happens when you put the planetary gears in mesh with the ring gear, and attempt to add the sun gear? How much is it off? Try marking each planetary gear in exactly the same spot (center tooth or something) and clock them in a certain position for reference. I works fine but I'm wondering if anyone has a better idea? Hmmmmm.Īlso, as I mentioned, I used a microwave turntable motor as a drive motor. It tells you on the page that the sun gear has 20 teeth, the planet gears 37 and the ring gear 92, but when I replicate it, it doesn't mesh up. I'd like my next "electric wall sculpture" to be similar to this cool looking design: I'm not sure it's the ultimate answer, but it's free and I'm having fun with it. Terry - Inkscape is cool! It does indeed generate gears that are easily saved as an. You say it will output dxf if you buy the program? Are you sure about that? I was under the impression that it's for printing out designs for scroll saw work only. Unfortunately, the free version doesn't let you output files to test for CNC and I'm not quite ready to plunk down $75.00 just yet, but the program looks to be simple enough and straightforward with lots of tutorial videos to watch on YouTube. Jack - Gearotic looks like the Mac Daddy for gear design.
