BEARING ASSEMBLY WITH DOUBLE INJECTION OF LIQUID LUBRICANT AND AIRCRAFT CONTAINING AT LEAST ONE SUCH ASSEMBLY Russian patent published in 2010 - IPC F16C33/66 

FIELD: transport.

SUBSTANCE: bearing assembly (4) includes fixed part (6), rotating part (8) and bearing (10) inserted between parts (6, 8). Bearing includes inner race (14) and outer race (12), each of which has track (16, 18) contacting rolling elements (20). Race (12) is fixed on part (6), and race (14) - on rotating part (8). Drain holes (24) pass through race (12). Assembly (4) also has the first injector (32) intended to supply non-reusable liquid lubricant and the second injector (42) which is automatically fed with liquid lubricant drained through collecting device (38) for collection of liquid lubricant leaving holes (24). Device (38) is interconnected with repeated injection circuit (40) connected to injector (42) and to bypass circuit (48) intended to remove the excess drained liquid lubricant. There also proposed is the aircraft equipped with shaft-turbine engine which includes at least one above assembly (4). At that, part (8) is rotor shaft of engine, and part (6) is engine housing. Injector (32) is fed solely with liquid lubricant from fuel tank (36) of the aircraft.

EFFECT: decreasing weight and dimensions of the assembly, reducing the consumption of liquid lubricant taken from the tank.
