Centrifugal hydrodynamic bearing

grabcad

A thought experiment in bearing design. Would require a very, very dense fluid such as mercury to even begin to work. No real indication this could even work at all, let alone work well enough to be useful.The basic idea is that the rotational movement of the bearing hub starts spinning the mercury inside the bearing case (blue) faster and faster until the centrifugal force stabilises the mercury into a spinning ring inside the bearing case. Which the hub can then float on and not touch the bearing case at all. And also lift off of the roller bearings which the hub would have spun on up until that point.The bearing incorporates two roller bearings to roll on until the mercury working fluid inside the bearing case has gathered sufficient angular velocity to where its centrifugal force is sufficient for it to displace the bearing hub (red part) and thereby allow the hub to float on it.
