ELASTIC-DAMPING SUPPORT FOR ROTOR MACHINE Russian patent published in 2009 - IPC F01D25/16 

FIELD: mechanical engineering.

SUBSTANCE: elastic-damping support for rotor machine refers to bearing assemblies of rotor engines. Installation on opposite to tapered shelf butt of head body which head together with cylindrical vent in stator element forms closed cavity over body surface makes possible to get power cylinder structure where the head rigidly connected with butt end of axially movable body represents moving piston, and stator element functions as cylinder body. Connection of this cavity with pressure source - oil chamber of rotor machine - makes possible to shift butt end of movable body relative to tapered butt end of stator element for optimum design value on the one hand providing assured pressing of mating tapered surfaces, on the other hand providing optimum strength properties of split bushing with slots.

EFFECT: providing optimum axial load on split bushing of support assuring seat on tapered shelves of body and stator element and not resulting in failure of split bushing; range of use extension for the device through spreading possibility of application of such support with any type of bearings.
