Geneva Mechanism Simulation

While wandering around the web looking for interesting mechanisms, I stumbled upon, for the gazillionth time, Geneva mechanisms. Even though I had looked at Geneva mechanisms more times than I can count, this time I discovered something interesting; A Geneva mechanism can be built without the anti-slip disk….

Linkage Beta Improvements

I updated the Linkage beta software: https://www.rectorsquid.com/beta/linkage.msi Here are some of the recent changes and additions: Allow gears to be separated using the Split command Show RPM along with gear radius or diameter when auto-dimensions are on. Added push/pull options to the actuator settings so users don’t need…

Another Bridge Mechanism

I threw together this bridge after seeing some others on YouTube. I started with actuators in place of winches and cables and then moved to an actuator that would be a hydraulic cylinder or rack-and-pinion if built in real life. I’ll try to update this post with the…

Rolling Bridge Mechanism

The rolling bridge in Paddington London is a prime mechanism to reverse engineer and create with the Linkage software. This is a simple repeating mechanism that uses the vertically-oriented hydraulics to decrease the distance between the top portions of the individual trapezoids. The distance decreases as the center…
