FIELD: engines and pumps.
SUBSTANCE: elasticity-damper support with adjustable stiffness contains the bearing on the shaft, stator element and mounted on outer ring drum which are connected with the statornym element by means of pin bushings. Elasticity-damper support additionally contains a sliding sleeve connected with stator element, which is located between the sidewall and the stator element with the possibility of simultaneous contacting sidewall and split sleeve through rolling offset drive along the longitudinal axis of the bearing. Split sleeve forms with sidewall damping cavity, bounded by the seals.
EFFECT: invention allows to change the amplitude-frequency characteristics of a rotor, to ensure its continued work on non-critical speeds and reduce vibration of stand and rotor.
