ACTIVE HYDROSTATIC SUPPORT WITH REGULATED PRESSURE OF LUBE MATERIAL SUPPLY Russian patent published in 2018 - IPC F16C32/06 B23Q1/38 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in rotating, high-loaded rotor machines. Active hydrostatic support with a controllable supply pressure of the lubricant comprises a body in which radially outgoing openings are formed, shaft interacting by means of an oil wedge with radially arranged pockets, which are grooves, for example made in the form of openings, which, in its turn, are connected through throttles with a supply main. Pockets are made on the inner surface of the bearing sleeve installed in the body, in which motion sensors are connected through a control system with linear drives of electromagnetic, piezoelectric, hydraulic, pneumatic, magnetostrictive or combined operation principle, changing the position of the shut-off and regulating elements of the throttles mounted in the body of the hydrostatic support and in the sleeve of the plain bearing, in which the outlet openings for the drain lines are additionally made.

EFFECT: improvement of dynamic characteristics, increase of reliability and resource of the "rotor-support" system, avoidance of unfavorable modes of support operation, due to application of the software and hardware complex, reduction of mass-dimensions.
