Controlling Different Rotational Speed Of Two Interacting Objects enter link description hereI have a problem modeling a Geneva Gear with two rotating parts, a cam which is driving a spur gear. The cam rotates continually, but the spur gear rotates by the action of the cam. I either need to slow down the rotation of the spur gear or make it interactive with the cam. BTW, I'm a noob.

Please download Blender file and run animation. I am not going to render the animation. It's fine the way it is.
You can use drivers to achieve this. Here is a demonstration: https://www.youtube.com/watch?v=ajMAvKRCTBg

Have fun!
