FIELD: engines and pumps.
SUBSTANCE: compressor of low-pressure gas turbine engine includes a rotor, front and rear trunnion is installed in the front and rear of the stator poles, respectively, ball bearing, a supporting sleeve, hinged V-shaped gears and thrust ring. The outer ring of the ball bearing is installed in the housing connected to the front support body by means of a releasable connection, and the inner ring of the ball bearing installed on the outer diameter of the auxiliary sleeve. At the front end of the trunnion installed rotor thrust ring connected to said supporting sleeve by means of circumferentially spaced relative to the longitudinal axis of the compressor V-shaped hinge mechanisms. Each V-shaped mechanism formed by two rockers, connected to one another by articulation, at the location of their connection is set load located on a smaller diameter than the diameter of the inner ring of the auxiliary sleeve. The free ends are connected to the rocking of the auxiliary sleeve and the thrust ring by means of articulated joints respectively.
EFFECT: invention improves the reliability of the low-pressure compressor operation of the gas turbine engine.
