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

FIELD: motors and pumps.

SUBSTANCE: invention relates to the field of engine building, in particular, of aviation applications, namely to devices for lubricating bearings of a rotary machine operating on grease. Rotor support of the turbomachine with grease contains hollow shaft (1), housing (2), bearing (3) with outer (4) and inner (5) rings, separator (6) and rolling elements (7), cooling channels (8), made in hollow shaft (1) and body (2). Cavities with used grease (9) are made in lids (10) installed in body (1) on both sides of the bearing. Support comprises grease supply device (11) installed in hollow shaft (1) and communicated with inner ring (5) through the oil supply channels of hollow shaft (1). Device (11) comprises cylinder (13) with cavity (14), filled with a grease, pressed on one side by pushing member (15), on the other hand, communicating with holes (16) in cylinder (13), which can be combined with holes (17) made in movable shutter (18). Device (11) also comprises cam mechanism (19) pivotally connected to cylinder (13). Between the end face of movable shutter (18) and the end of cylinder (13), cavity (20) is formed with installed axial spring (21) and associated with holes (17) of movable shutter (18) and oil supply channels (12) of hollow shaft (1) and inner ring (5) of bearing (3) comprising at least one groove (22).

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