Infinite variable Transmission (IVT) Hub
grabcad
My Infinite Variable Transmission hub concept aims to be shared on GrabCad for potential realization. This design is open to enhancements, and I've used a downloaded free wheel sprocket from GC library for my bike hub. This idea, however, has wide applicability. Although time-intensive, it can be 3D printed (except needle bearings) and features a planetary gear system with a stationary sun gear, spinning tapered planet gears, and rotating ring gear hub. Adjustable sun gear positioning provides variable ratios.
