Non Rotating Orbit - Educational Model

My Educational Mechanical Examples SeriesThis model is one of my educational mechanical mechanism examples on 80mm x 80mm base plates.You can find all models of the series in this collection => [Mechanical Mechanism Examples] The present modelThis simple but intriguing model demonstrates how a three spur-gear train can keep a gear’s orientation unchanged while it orbits around a fixed pivot.Brief DescriptionThis simple but intriguing model demonstrates how a three spur-gear train can keep a gear’s orientation unchanged while it orbits around a fixed pivot. A related idea is used in the Falkirk Wheel (Scottish Gaelic: Cuibhle na h-Eaglaise Brice), a rotating boat lift located in Tamfourhill, Falkirk, in central Scotland. There, the two boat lifts are kept leveled while rotating around the pivot as in the pictures below.See also: https://en.wikipedia.org/wiki/Falkirk_Wheel <img class="image_resized" style="width: 45.16%" src="
