COMBINED SUPPORT WITH ELASTIC ELEMENTS Russian patent published in 2016 - IPC F16C21/00 

FIELD: machine building.

SUBSTANCE: invention can be used in rotating, high-loaded rotor machines. Combination support includes housing and installed in it in series on shaft of rolling bearing, external ring of which is installed in housing by means of flexible rings so that bearing may move relative to shaft axis in radial direction under action of external loads, and sliding bearing. With increase in RPM in channels of sliding bearing there is hybrid reaction, reducing load on rolling bearing, as result of external load is redistributed between rolling bearing and journal bearing. On inner surface of casing piezoactuators are installed connected to voltage source and capable of as a result of own deformations to move movable shoes relative to shaft axis in axial direction.

EFFECT: higher reliability, durability, improved dynamic characteristics of rotor-support and reduced rotor vibration amplitude due to activation, deactivation of resilient rings by means of changing voltage supplied to piezoactuators.
