FIELD: mechanical engineering.
SUBSTANCE: low-pressure compressor rotor shaft bearing is located in the intermediate casing of the engine and contains the embodiment of the ball bearing, dividing the support into the stator and rotor parts. The stator portion of the inner side is formed integrally with the outer ring of the ball bearing, and the outer perimeter is secured to the motor housing and the intermediate holder is provided with a labyrinth seal caps. Rotary part includes a pin of the reel disc component of the rotor shaft, which is detachably connected to the cylindrical part of the rotor shaft, through which the rotor part is supported on the inner ring of the ball bearing, and also contains a polyfunctional external coupling element in the form of circular cylindrical nut and the connecting element has a hollow bolt shape. The rotor and stator of the support are in the oil environment, which is usual for them. The support housing is equipped with additional holes for the oil change and removal of oil if necessary.
EFFECT: invention allows to adapt the low-pressure compressor, a part of the engine to be more sensitive to external mode proceeds airflow intensive work in fixed ground operation conditions.
