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, body, bearing with outer and inner rings, separator and rolling bodies, actuators symmetrically mounted on both sides of the bearing, container with grease, made between the actuators and the bearing. Each actuators comprises an axially movable impeller mounted on the limited in the axial direction fixed bushing. Impeller lower end rests against an axial spring mounted on a stationary bushing and in contacting with the bearing inner ring, at that, a piston element is installed with the possibility of contact between the impeller upper end and the spring, which outer surface is contacting with the sealing cap rigidly fixed in the bearing housing. In the hollow shaft and the bearing housing, cooling openings are made, communicating with the air cavity formed between the impeller and the piston element.

EFFECT: increase in the turbomachine with grease lubricant rotor support operating life due to increase in the operation reliability, as well as the expansion of operational capabilities through the use in the aviation field of a design on high-speed rotor bearings.
