MULTI-LEAF GAS-DYNAMIC BEARING WITH ACTIVE CONTROL Russian patent published in 2016 - IPC F16C17/12 F16C27/02 F16C32/06 

FIELD: machine building.

SUBSTANCE: invention relates to turbomachine building and can be used as support of high-speed rotors of machines and units loaded with radial loads, in aircraft cabin air conditioning systems, as well as turbo systems in modern car industry. Multi-leaf gas-dynamic actively controlled bearing comprises housing in slots of which overlapping blades are inserted, said blades arranged uniformly along circumference of housing. Piezoelectric actuators are inserted into housing, on which rest blades, which also enable to collect data on position of shaft and bearing surface deformations and to vary rigidity of supporting surface.

EFFECT: technical result is improvement of reliability and durability of bearing assembly, longer service life, stability of movement and suppression of beats of shafts and rotors due to piezoelectric actuator by means of which it is possible to monitor and control rigidity of bearing surface.
