GAS-STATIC THRUST-AXIAL BEARING WITH PNEUMATIC CONTROLLER OF SHAFT POSITION Russian patent published in 2009 - IPC F16C32/06 G05B11/44 

FIELD: machine building.

SUBSTANCE: invention is related to pneumatically controlled thrust-axial gas-static sliding bearings and may be used in turbines. Bearing comprises body, shaft (2), thrust disc (1), which is rigidly put on bearing shaft (2) and installed between fixed supports (3, 4) of body on both sides of disc (1), group of pair throttles (7-14) of feeders, which are axially opposite and separated by disc (1). Inlet channels of controller (21) for control of shaft position (2) are connected by communication pipelines (17, 18) with indicator nozzles (5, 6), which are arranged in the same body. At that indicator nozzles (5, 6) are coaxially opposite, are separated by disc (1), are installed diametrically closer to bearing center compared to pair throttles of feeders (7-14), and they create elements nozzle-gate with disc (1). Outlet channels (22, 23) of controller are connected by communication pipelines with membrane-plate units (26, 27), which are arranged with self-centered plates (30, 31), which have guide surface. Outlets of units (26, 27) are connected by communication pipelines with according group of pair throttles (7-14) of feeders.

EFFECT: increased reliability.
