Flying Tourbillon Model IV (Dual Ulysse Escapement)

thingiverse

Here's another tourbillon model that incorporates Ludwig Oeschlin's impressive Dual Ulysse escapement, inspired by Breuget's innovative natural escapement. This design features a unique tooth profile, where each escape wheel tooth acts as both an impulse and locking pallet, while also powering the other. However, this approach comes with its own set of challenges: it demands extra energy to overcome the inertia of two escape wheels, and requires greater precision than traditional Swiss levers. Ulysse Nardin's Freak series is a notable example of this escapement in action. I created this design because I don't have $100,000 to spend on my mechanical toys. This prototype is still a work-in-progress, with PLA shafts serving as a proof of concept until my shaft stock arrives. Once that happens, I'll be able to fine-tune its functionality and assess its performance more accurately. UPDATE: The non-printed components include 2mm steel shafts (available on Amazon) cut to size based on my PLA mockups, a single 607 bearing (22x8x7 in size), and 1mm spacers that can be printed. User animoose has shared a Blender model of the assembled mechanism in the comments section, providing a visual representation of how all the parts come together.
