FIELD: engines and pumps.
SUBSTANCE: proposed system comprises circulation system of bearing assy lubrication including oil feed system and breathing system, their lubing channels being made in gas turbine engine bearer ribs. This system incorporates rpm contactless transducer fitted at engine stator parts, inductor composed of gear wheel fitted at gas turbine engine rotor under rpm transducer. Transducer tubular case is divided in two parts at joint with T-bend. Compensator is arranged between T-bend and rpm transducer. Cylindrical thrust ledge is made at transducer tubular case lower part, immediately before oil cavity chamber to limit the case radial displacement toward engine rotor.
EFFECT: higher reliability and accuracy.
