Transmission between three shafts (NO GEARS)

cults3d

I'm fascinated by shafting without gears, so I built a working model of the Unique 1884 Patented Almond Coupling For Shafting. Check it out here: https://www.thingiverse.com/thing:3413776. Then, I stumbled upon an impressive three-axis design on GrabCAD by Nal. Take a look at this: https://grabcad.com/library/transmission-between-three-shafts-transmission-entre-trois-axes-1. This transmission is purely fictional, and you can animate everything, but I wanted to test its feasibility. So, I created a 3D printable proof of concept. Guess what? It actually works! Watching it in motion is captivating, and studying the movements is enlightening. I also made sure it's aesthetically pleasing and easy to hold. The Carter opens and closes effortlessly, making it an excellent educational tool for students to explore various loads and forces. Printing it isn't too challenging, but keep in mind that the pistons need to be printed inside the crank. It's a print within a print! In your slicer program, position the piston upright on the flat spot in the middle of the crack. There should be enough clearance for most printer setups. Have fun with it! Please like, share, make, and let me know if you use it for educational purposes.
