The Möbius Gear
- wbhart 16y agoBut I want to see it turn!
- gpambrozio 16y agoSecond that. But I would would settel at least for more angles of this.
- mjs 16y agoAgreed. Video or I say it doesn't rotate!
- RodgerTheGreat 16y agoHave a gear cube as a consolation prize: http://www.youtube.com/watch?v=qfspDCpVDTw http://www.youtube.com/watch?v=qfspDCpVDTw
- svag 16y agoI was trying to view the description of the entire process (using this link http://robotics.eecs.berkeley.edu/~ahoover/CS285/FinalProject/AHoover285FinalProject.pdf http://robotics.eecs.berkeley.edu/~ahoover/CS285/FinalProjec...) but I get a 404 error. I don't know if this is only for me, but I found a report regarding this project here http://www.cs.berkeley.edu/~sequin/CS285/PROJ_06/A_Hoover/AHoover_Report.pdf http://www.cs.berkeley.edu/~sequin/CS285/PROJ_06/A_Hoover/AH...
- ddol 16y agoI like this quote from the conclusion: "The most important lesson to be taken from my experience with this project is that no single tool is sufficient to solve a reasonably complicated engineering problem"
- intended 16y ago"SLIDE proved to be difficult because adding additional sweeps to the existing file began to cause SLIDE to crash." "In an ideal world an open standard interchange format that allows users to move between different modeling packages, leveraging the strengths of each to solve complex design problems, would be available and implemented by all major modeling packages." That was interesting to read in the article. Having never worked with solid works or Slide, it was nice to be made aware of the issues faced in that field of work.
- hammock 16y agoWhat are the applications of this? Or is that a blasphemous question to ask?
- phreeza 16y agoI know that Möbius strips have applications in real engines. Fanbelts for example are möbius strips because they get worn equally over the whole surface that way. Perhaps there could be a similar use case for a gear like this,but I have never heard of any.
- buro9 16y agoUsually gears have a prime number of teeth on the cogs involved if possible, and different prime numbers at that. This ensures that wear is even which helps with the longevity of the parts and also ensures smooth-running as there will be no uneven wear on one part of a cog. Another side effect is to spread oil evenly across all teeth in a reasonably short running time. I cannot see how a mobius gear would offer any significant benefits over this. Most cogs are already machined to fit each other neatly, and the problem with fan belts (uneven wear) doesn't really apply to gears.
- temptemptemp13 16y agoWhy would a prime number of teeth be beneficial? Every full rotation, all n teeth should have the same amount of wear.
- shasta 16y agoPresumably the desired condition is that gcd(n,m) = 1 (the number of teeth be relatively prime) so that each tooth of one gear meets with each tooth of the second gear, cyclically. If there are variations/defects in teeth, this might help them wear more uniformly.
- hammock 16y agoIt's a cool insight that I just learned, but if the two gears share a multiple, then the same teeth will engage with each other over and over leading to uneven wear pattern. If the gears are relatively prime (e.g. 6 and 17) then each tooth will touch each other tooth before repeating the cycle. Try it out on a piece of paper and see for yourself (that's what I did).
- JoeAltmaier 16y agoLooks like the 'planetary' gears should be conical instead of cylindrical?
- aphistic 16y agoI'd like to know where I can buy one, I don't have access to any 3D printers and I think this looks like something I'd like to have in my office.
- skeltoac 16y agoI saw the leading photo (no supporting text) on a disreputable image board last week. OP was asking what it was, everyone else was getting their minds blown. I went right to Google, typed "mobius gear" and found out. The image did spur a few mental gusts but seeing it here a few days after seeing it there... mind blown.
