Classic Escapement - Graham (Ideal)

grabcad

The original text presents a detailed explanation of the Graham (dead-beat) escapement mechanism from Mark V. Headrick's book on clock and watch escapement mechanics. The author aims to create projects to help understand the concepts better using Inventor 2014 software. The first project is an ideal version of the Graham escapement, explained in the book up to page 11, "The Importance of the Simulation." It includes a wheel and palette with no clearance, and when simulated, it shows that the wheel gets stuck between two teeth due to insufficient clearance. The author suggests checking out the next project (Classic Escapement - Graham (Modified)) to see the mechanism working correctly. Additionally, the author notes an eccentric hole on the wheel to help Inventor's Dynamic Simulation module automatically create a revolution joint for the wheel. The provided text explains the concept of the Graham escapement from Headrick's book and demonstrates its simulation using Inventor 2014 software. The author highlights the limitations of the first project, which is an ideal version without clearance, and encourages readers to explore the next project for a properly functioning mechanism.
