FIELD: mechanical engineering. SUBSTANCE: invention relates to rotor supports of gas-turbine engines. Elastic-damping support has a body which cover with immovable flange is secured, and elastic-damping bushing with outer bearing race secured in it is arranged. Moving flange is positioned between outer bearing race and elastic-damping bushing for radial movement relative to cover. Flange is provided with two spaced radial projections with circular grooves which accommodate elastic split rings contacting immovable flange surface for their displacement through height of grooves. Invention makes it possible to enhance engine operation reliability due to reduction of hot-air leakages into oil space of support and improvement of operating conditions of bearing and contact seal of support labyrinth. EFFECT: enhanced efficiency. 3 dwg
