Balancing High-Speed Light Rotors Resting on Bearings with Gas Lubrication,
Abstract
Under the influence of disbalance due to compression of the gassy layer in the bearing, the center of gravity of the rotor describes a circle, the radius of which exceeds its eccentricity in proportion to the angular velocity of rotation, i.e., the geometrical center of the journal also describes a circle of constantly greater radius, increasing the compression of the gas layers. At a certain increase of the inflexibility of the gas layer, so called inversion takes place: a transition accompanied by a sharp increase in the oscillation amplitude of the journal, after which the rotor begins to rotate about the center of gravity with smaller oscillations, which are close to the value of residual eccentricity.
