A simple concept to animate multi mates at once

olaf_huber644

I am playing around a bit with the assembly capabilities of Onshape to model/animate assembly motion.
Currently the animation option is restricted to one mate at a time.
But often in reality you have machines with several mechanisms working simultaneously together in a cyclic manner (either mechnically or electronically coupled).
And you want to animate these together and not only one at a time.

Assuming that the different motions follow a 360° cycle ("Königswelle" in German, I believe the term is master cam in English) the "Relations" offer an easy way to accomplish this.
I built up a test assembly with

• one slider mate
• one revolute mate

 and related those to a "master wheel" (revolute) by means of rack/pinion and gear.
I guess you can easily apply this concept to a literally larger number of mates.

I try to share this document by a link (first time), I am happy to hear your feedback.

That is cool!

That's pretty much the foundation for the rubik's cube animation

With a little bit of patience and lot of beer, you can take that concept to a whole new level

That still looks amazing! I'd still be in phase of trying to solve the rubik's in first place to be able to start reverse engineering for the movement
