Original project made with Autodesk Inventor 2014 as a Dynamic Simulation. The action is due to a imposed motion applied to the crank (20 rot/min = 120 deg/s) and no gravitation.

The purpose of this mechanism is to convert a continuous rotation motion of the crank into an oscillating motion of the fork, with a long dwell in a cycle.

The crank is rotated by handle and the roller engage the fork channel. Remarkable is that when the fork comes back to the dwell period its inertial movement is blocked by the mutual contact of the locking parts.

The small clearance between the locking parts insures the freedom of small movements for accommodating the contacts.

The animation is obtained by transferring data from the Dynamic Simulation to Inventor Studio with the „Publish to Studio” tool.

If you use Inventor, you have to download all the files in a single directory, then open the .iam file with Inventor 2014, 2015..., enter Environments/Dynamic Simulation and click on Play button. Instead of 6000 images you can apply 1200 images if you have to wait too much for the simulation.

Enjoy!
