p.s., I have a 35 1.4 that is in several pieces in the repair shop. It has a ring motor. Nikon does makes "mini DC motors" and markets them as "Silent Wave Motors" implying they are ring motors. Those are what you are describing. These can be found on most DX lenses and certain variable aperture FX and DX zoom lenses. Those do have gears.
