Planetary Gear

prusaprinters

<p>Gear has a 1:1 ratio. One turn inside will also turn the outside exactly one round.</p> <p>Video: <a href="https://vimeo.com/456871494">https://vimeo.com/456871494</a></p> <p>Design:</p> <ul> <li>Fusion 360 -&gt; Tools -&gt; Add-ins -&gt; Spur Gear</li> <li>Fusion 360 -&gt; Solid -&gt; Create -&gt; FM Gears (Internal Gear)</li> </ul> <p>Design Notes:</p> <ul> <li>FM Gear does not use any offset. To counter that I made the module slightly larger.</li> <li>Instead of using FM Gear you could also create a normal gear and use it to cut out the internal gear from a round solid. But don't use any Backlash for this one.</li> </ul> <p>Wiki: <a href="https://en.wikipedia.org/wiki/Epicyclic_gearing">https://en.wikipedia.org/wiki/Epicyclic_gearing</a><br/> FM Gear: <a href="https://apps.autodesk.com/FUSION/en/Detail/Index?id=6294804001663532834">https://apps.autodesk.com/FUSION/en/Detail/Index?id=6294804001663532834</a></p> <h3>Print instructions</h3><p>I used PETG since it sticks very well to the print bed. With PLA I have often problems if I have fine details in the first layer.</p>
