The contact regimes in the rotor system when the contact of the rotor with light movable elements of the system have been considered The vibrations of an imbalanced rotor–floating ring system when rotating the rotor inside the floating ring when permanent contact with them have been investigated. Furthermore, the ring vibrations occur, during of which it runs the rotor when permanent contact with it in the direct precession regime (the precession direction coincides with the rotation direction) (hula hoop-type vibration). This article considers the kinematics of ring motion. The trajectories of ring motion in both absolute and relative motion at different ratios between the radii of the ring and rotor have been plotted. It has been revealed that the ring vibrations are a direct asynchronous precession; furthermore, the ring points circumscribe epitrochoids and the trajectory shape depends significantly on the ratio between the radii of the rotor and the ring.
