MULTILOBAL MECHATRONIC GAS-DYNAMIC BEARING Russian patent published in 2019 - IPC F16C17/12 F16C27/02 F16C32/06 

FIELD: machine building.

SUBSTANCE: invention relates to turbomachine building and can be used as supports of high-speed rotors of machines and units loaded with radial loads in air conditioning systems of aircraft cabins, as well as systems of turbo-supercharging in modern motor industry. Multilobal mechatronic gas-dynamic bearing comprises housing, in grooves of which lobes are inserted to each other lobes located uniformly along circumference of housing, and piezo actuators. Thin lobes rest on sectional springs inserted into longitudinal grooves of the housing and taking up load at absence of electric voltage. At that, piezo-actuators arranged along rotor axis make it possible to form conical and barrel-like resilient surface.

EFFECT: improved dynamic characteristics of high-speed rotor, increased reliability and durability of bearing assembly, as well as resource of operation at multiple start-ups and stops due to piezo-actuators, by means of which it is possible to control and manage rigidity of support surface in axial and radial directions.
