TURBOMACHINE WITH GREASE LUBRICANT ROTOR SUPPORT Russian patent published in 2018 - IPC F16C27/00 F02C7/06 F16C33/66 

FIELD: engines and pumps.

SUBSTANCE: invention relates to the field of engines building, in particular of aviation application, namely to rotary machine bearings lubricating devices operating on a grease lubricant. Turbomachine with grease rotor support contains a hollow shaft (1), body (2), bearing (3) with outer (4) and inner (5) rings, separator (6) and rolling bodies (7), made in the hollow shaft (1) and the body (2) cooling channels (8), cavities (9) with the used grease, made in the covers (10), installed in the body (2) on both sides of the bearing (3). Support comprises grease supply device (11) including cylinder (12) mounted in the shaft (1) with the filled with grease cavity (13). On one side cavity (13) is pressed by the made in the form of graphite piston (15) pushing element (14), pressed by the elastic element (16) contacting the fixed in the cylinder (12) cover (17), and from the other side is communicating with the oil supply channels (18) through the holes (19) in the cylinder (12), communicating with the inner ring (5), containing at least one groove (20). Graphite piston (15) central part contacts the mechanically connected to the body (2) stationary rod (21).

EFFECT: increase in the turbomachine with grease lubricant rotor support operating life due to grease supply device.
