Review & evidence

Geometrical evidence

The complete solid anchor and both pallets share the escape wheel’s working plane. Teeth have a finite relieved tip land. The 4,001 sampled poses are not a continuous collision proof or manufacturing qualification.

One coherent power and timing chain

Driver / followerModuleAxial plane
1.0 s per oscillation × 30 teeth = 30 s per escape revolution

Production boundary

This is a nominal mechanical reconstruction and an interactive visualization, not a manufacturing release or a certified digital twin. No particular historical manufacturer’s dimensions were supplied. Friction, spring torque, inertia transients, flexure stiffness, wear, lubrication, strength, fits and real tip radii would still require CAD engineering and physical qualification.

The spring is a bounded, non-self-intersecting energy illustration. Wind replenishes the modeled reserve; it is not a torque-resolved winding simulation. The exploded view pauses the mechanism and intentionally disconnects the axial layers. GLB export captures a static assembly, not the regulator model.

Explore the movement

Start at real speed. Then slow it down.

Drag to orbit, select the scene and scroll or pinch to zoom, and right-drag to pan. Choose Movement to remove the case, chapter rings and front plate without altering the assembled gear positions. Select Escapement and 0.1× speed to see lock → impulse → drop.

+1 beat pauses and advances exactly 0.5 seconds of simulation. Both pallets remain part of the same contact solver. Exploded separates the axial modules and pauses them; it is an inspection layout, not an operating configuration.

Inspect and export

Use the component menu or turn on labels to identify each assembly. Pitch circles show the nominal meshing distances; they are engineering overlays, not physical material. PNG exports the 3D viewport. GLB exports the currently visible model in meters, with named meshes and basic PBR materials.

Keyboard

With the scene selected: Space play/pause · N one beat · H studio view · M complete/movement · L labels · R reset time and view · Esc releases the scene.

The clock pauses when its tab is hidden; no artificial catch-up is applied. A reduced-motion preference starts it paused.

Verification checks

Center distances, gear phases, timing and state invariants. The full polygon collision sampling is in the bundled evidence and is not rerun by this button.

Sampling is not a continuous collision proof. See Review & evidence for the scope of the mechanical reconstruction.
