FIELD: machine building.
SUBSTANCE: invention relates to gas turbine engine building and can be used in engines with rigid limitations in overall dimensions and weight. Support of the rotor with grease contains a housing, a hollow shaft inside which a portioner is located, in the form of a hollow cylinder, with a movable element in the form of a piston, on one side of which there is a cavity with a consistent lubricant, and on the other side there is an elastic element in form of a spring, a bearing with outer and inner rings, a separator and rolling elements, cooling channels made in walls of the hollow shaft and housing, wherein cavity with consistent lubrication is communicated via oil supply channels made in wall of hollow shaft and portioner with inner ring of bearing. Elastic element is made in the form of spring and is installed between piston and annular ledge, made inside portioner. Inside the portioner an electromagnet is installed cantilever along the axis, installed on the stator element, and in end wall of piston from side of spring along axis screwed in limiter in form of metal screw, and between electromagnet and limiter there is always a gap.
EFFECT: technical result is increased service life of bearing with bearing on grease due to discrete supply of new portion of lubrication to points of contact of solids of rolling with rings and separator in entire range of GTE operation.
