Abstract

El cojinete de levitación fluídica por repulsión inversa objeto de la invención sustenta radial y/o axialmente rotores mediante levitación fluídica conseguida por repulsión inversa hidrostática, o tracción mecánica hidrostática. El estator está dotado en las zonas de sustentación radial y axial del rotor de huecos o cámaras rellenadas con un fluido a presión (normalmente aceite) que es inyectado a través de orificios restrictores de fluido que capacita al rotor para sustentarse en una posición auto-levitante y evitar el contacto entre el estátor y el rotor, de modo que al separarse el rotor del estátor aumenta la fuga de fluido contribuyendo a la disminución de presión del fluido y a la aproximación del rotor al estátor, con lo que se estabiliza en una posición auto-levitante de equilibrio.The fluidic levitation bearing by reverse repulsion object of the invention supports radially and / or axially rotors by means of fluidic levitation achieved by hydrostatic reverse repulsion, or hydrostatic mechanical traction. The stator is provided in the radial and axial bearing areas of the rotor of holes or chambers filled with a pressurized fluid (usually oil) that is injected through fluid restrictor holes that enables the rotor to support itself in a self-levitating position. and avoid contact between the stator and the rotor, so that separating the rotor from the stator increases fluid leakage contributing to the decrease in fluid pressure and the approach of the rotor to the stator, thereby stabilizing in an auto position -balance equilibrium.
