FRONT SUPPORT OF LP TURBINE ROTOR OF TWO-SHAFT GAS TURBINE ENGINE

摘要

FIELD: engines and pumps.SUBSTANCE: bearing is designed radial-thrust, splines and mating splines of one of splined joints are designed screw-type in the shape of multi-start thread, which threads are directed to the opposite side from direction of HP rotor rotation with possibility of axial displacement of a spring to create axial force on outer ring of the bearing during engine operation after the mode of its start. Also there is a fixing device restricting axial displacement of the spring in direction from the bearing.EFFECT: eliminating defect of slipping motion during engine operation.2 cl, 3 dwg
