Fractal Wheel Bearing

cults3d

Fighting climate change, this is a 100% open-source 3D printable bearing that uses a revolutionary new method to create a bearing without a cage. This Fractal Wheel Bearing is one of many innovative products resulting from the emerging science of fractal gear field theory. It's made using fracs and is topologically equivalent to a standard roller bearing without a cage, but its motion is uniquely different. A frac is like a large sphere condensed into a smaller sphere, which allows for smooth "sphere-on-sphere" motion by eliminating the bearing cage. This makes it a 3D printable geometry that can outperform standard bearings in many ways. Compared to planetary fractal gears and bearings (available for download here: https://cults3d.com/en/3d-model/tool/planetary-fractal-gear-and-bearing), this fractal wheel bearing is better suited for use as a bearing only, without gearing. It can also be used as an energy return wheel when the interior fractal gears are printed from elastic materials like pro-flex airless tire filament.

The fractal gear principle in linear movement is showcased here: https://www.youtube.com/watch?v=e6epepGdnmg. To print the Fractal Wheel Bearing, it's recommended to print the center hub, 6 fractal gears, and outer shell in halves, then glue everything together. This approach avoids the need for supports on most machines. The downloadable files include both full and halved STL models for each part, allowing users to choose the best printing method for their needs. The assembly requires either the center hub or outer rim to be printed in fastenable halves to facilitate disassembly. Otherwise, it will remain permanently assembled. The inventor claims that this design may hold the key to building an ancient Egyptian pyramid and could even surpass modern bearing designs for heavy lifting tasks. Fractal gear forms, while complex, exist naturally in many forms, such as cactus plants, corals, sea urchins, and electromagnetic fields on ferrofluids. This suggests that ancient peoples could have used these natural forms to create similar structures. To learn more about fractal gear field theory, visit www.facebook.com/makeoilworthless.
