Great tutorial. I didn't realize something so complex could be so simple. I also like how it is explained comprehensively and gives common pitfalls. Very useful website. :) It is called a Rack and pinion where the rack is the long linear gear and the pinion is the round one (FWIW).

I shall have to give it a try (got me a thing for gears). Question for me would be, what if the gears have different numbers of teeth? I suspect one would have to animate them individually (at least that's how I have done it, calculating the gear ratio). How did you make the gears? I have seen the gear script, but haven't done much with it myself. My normal method is to create the gears in Inkscape, then import the .svg file into Blender and extrude it. Another consideration, depending on what your intended purpose for animated gears is, is that you can get away with animating the gear "by just one tooth" (unless you have specialty gears that aren't symmetrical), saves on render time (I mostly do GIF files, and being able to animate an entire gear in just five frames is a must, it just keeps playing the gear rotating by one tooth over and over again, but the gear looks like it is doing a full rotation). The video below was done with my Inkscape extrusion technique, but not by "one tooth", obviously. http://www.youtube.com/watch?v=acXiebKExQM Very interesting tutorial.

I did the other way around. The location in x direction rotates my cylinder. This way I can do an eternal rotation. Thanks anyway. Ok. I did the other way around.

I have a scenario where I want to copy the rotation of a smaller cylinder to a bigger one. Do you know how could I rotate a cylinder copying the rotation of another smaller cylinder with an influence smaller than 1 and still make the bigger cylinder to make a complete turn? The bigger cylinder resets its turn when the smaller cylinder completer 360 degrees. Thanks. I appreciate a lot your tutorial. Tks Jonatan

I think this is not a question like chris has asked. thanks again thanks for the tut
