Infinite variable Transmission (IVT) Hub

grabcad

This is my Infinite variable transmission hub concept. I would like to present this idea to the GrabCad community to make this a reality someday. I would invite anyone to improve upon this design to something even better. This particular model is meant for a bicycle hub hence the free wheel sprocket I downloaded from GC library, but this concept could be use for any type of application. I spent many many hours on this project but definitely has room for improvement, and I believe this could be 3D printed except for the all purchased needle bearings. This concept is a basic planetary gear system with the sun gear being stationary and the planet gear are tapered spinning around the sun gear in which rotates the ring gear hub. The sun gear can be moved axially to achieve the variable gear ratios.
