Hello, I am trying to create a mechanism that will allow for a motor to power a pendulum-like motion (but not an actual pendulum), back and forth. As shown in the picture, I need 180 degrees of rotation about the swinging part. I have researched escapement, but I need this design not to rely on gravity and to move much faster than I imagine the anchor escapement works. Ideally, such a mechanism would minimize the loss of torque on the output gear, so that I can use this oscillating motion to accomplish other tasks in my application. I would appreciate any help you can provide!
