In this video, we’re going to use Fusion 360’s joint simulation ability to simulate the movement of a ninety degree gear joint!

• Creating MOVING HINGE ...
First things first - I’m really not trying to create a super accurate gear model, meaning a gear that’s exactly mathematically correct, but rather focusing on simulating the movement. This should get you close enough to create a visual approximation, and might even work if you were to 3D print the gears, but I have not gone through and done the calculations necessary to make this an exact mathematical gear model.
- Download gears from the McMaster Carr Library
- Place gears using the move tool
- Note this doesn’t have to be perfect for this application - just get close
- These gears are going to be built as as-built joints, or joints that are modeled in place, rather than normal joints, which move relative to each other
- Create an empty component, then put a sketch line inside the component. This will act as your ground component
- Create an as-built revolute joint between the sketch line and the gear
- Ground the sketch line component
- Do the same thing for the second gear
- Now, create a motion link between the two gears - the smaller gear should have a gear ratio half that of the larger gear
