Re: For twisted gearheads
Fascinating and a little head-hurting. Now what is the practical application?

Re: For twisted gearheads
Well, does it have to have one? Can't it be enjoyed just for its own elegant perversity?
But since you ask: the paradoxical gearset forms the basis of the Mercier differential, a torque-sensing differential developed by a M. Mercier of Renault Automobiles back in the 1980s. The Mercier differential was simpler in construction than the more popular Torsen differential. There's a brief paper on the subject at Professor Maurel's website here: http://www.jacquesmaurel.com/files/Exp ... 0gears.doc
Also, one of the videos at the site I posted originally has the most intuitively lucid explanation of the involute gear tooth profile that I've ever seen.

Re: For twisted gearheads
That is where I left off. "Elegant perversity". However, being curious (not a crime yet), I was wonderin if the damn thing had a practical application that I could not yet fathom but would want to know . . . like the myriad of other elegant perversities that I have been subjected to in my fifty eight years of learning about all number of elegant perversities, you know, like flywheel/crankshaft harmonics and stuff.
