It is often the case that a motion is designed for a Tool, but the Tool is not driven directly. A different Part drives the mechanism. The motion and forces are transmitted through the mechanism from a Driving-Part to the Tool-Part. Usually, with a Cam mechanism, the Driving-Part is an oscillating Cam-Follower that is moved by a Cam. There is also the case in which the Driving-Part completely rotates, but with a non-uniform rotating speed. This is a special-case. To make sure this can happen, the Driving-Part must be exactly the correct length. The Driving-Part becomes a Crank that rotates continuously in one direction as the Tool-Part moves with your motion-design. This is one application of the Continuous-Crank FB. |
Open Continuous-Crank FB dialog-box
Edit the Continuous-Crank FB:
The Continuous-Crank dialog-box is now open. |

STEP 2: Activate the Not Selected box
STEP 3: Click a Part that you want to be the Continuous-Crank
The Part immediately changes its length so that it can rotate continuously or oscillate by ~180º. If there is a problem - see Message at the bottom of the dialog. STEP 4: Confirm the behavior is as expected
STEP 5: Click Messages at the bottom of the dialog: When you select a Part as the Continuous Crank, there will be a Message.
