Hi everyone. I'm trying to design a product that translates rotational force (as in a static pressure, not an actual rotation or movement) from one frame of reference to another. The first sketch is a disk just to show the orientation. The rotation occurring in 1. (depicted by a crank end) must cause rotation of the entire crank arm & boom around a center frame of reference 2. Can someone direct me to an online library of mechanisms I can sift through? I'm not really clear what to call it so searching it is difficult. And no, toothed gears won't work for this application, because the crank doesn't actually rotate, only a rotational vector force is applied. That pressure vector creates the larger rotating vector in 2. Directions depicted and even the crank itself are arbitrary and not as important as the over-all motion.
