I can visualize that but with only one bearing on the driver armature, so the formerly flex ring is trapped between the bearing and the outer 2 parts. This would have the added advantage of needing only a 1 tooth difference, but would probably need a counterweight opposite the bearing as we've seen in cycloid designs, probably weighing as much as the bearing and floating ring combined for decent balance. Or, still thinking outside the box, even the triplet of small bearings on one end of the driving armature. Or better yet, a circular disk with a lot of empty space in it to keep the ring from flexing so much as it fly's around, with a smaller cheaper bearing centered in that disk, but being swung on an offcenter pin on the driving axle. With Sams fine teeth, but only a 1 tooth difference, a possible 400/1 ratio? The moving output ring might need to be restrained from resonane effects by a BIG and costly bearing in the final version but bolted to a stiff disk with a smaller double bearing'd output shaft might do for testing to see if its practical. > On Wednesday, January 27, 2021, 12:06:27 PM MST, Sam Sokolik > <samco...@gmail.com> wrote: > > well - that is the plan... but I need to create a decent housing to > mount it all... :) SMOM (simple matter of machining) > > On Wed, Jan 27, 2021 at 12:59 PM Chris Albertson > <albertson.ch...@gmail.com> > > wrote: > > Now, if you will, place it on a motor and run it for 24 hours and > > let us know what happens. > > > > On Wed, Jan 27, 2021 at 8:59 AM Sam Sokolik <samco...@gmail.com> wrote: > > > Nice being able to make things while I sleep.. > > > > > > 2 outside side rings - one 202 teeth - one 200 teeth. > > > Inside flex ring - 200 teeth.
