摘要

FIELD: engines.;SUBSTANCE: invention relates to engine building. GTE LPC rotor shaft front support comprises roller bearing, which separates support to stator and rotor parts. Stator part comprises support body, which is connected to roller bearing housing and covered with VGV hub with formation of compact annular cavities. One cavity is equipped with resilient ring. Other annular cavity contains shaft oscillations resilient damping element with system of resilient beams. Support stator part includes annular forming elements of air supercharging cavities, breathing and oil. Support rotor part comprises front support trunnion, consisting of hollow cylindrical section, with installed in it roller bearing inner ring and labyrinths two crested rings separating oil and breathing cavities, as well as breathing cavity and supercharging air cavity, which volume of is limited by labyrinth third crested ring, installed on trunnion conical diaphragm. Rotor shaft vibrations resilient damping element includes system of longitudinal resilient beams, located along support body perimeter with angular frequency of γp.b.k., defined in range of γp.b.k.= (7.2÷14.4) [units/rad]. Beams are separated by slits, which width in (1.1÷2.4) times exceeds beams width. Support body is equipped with three flanges, provided with groups of holes for alignment, attachment, dismantling and oil removal.;EFFECT: group of inventions technical result consists in engine stable operation operating modes range expansion with rotor shaft vibrations damping without entering into resonance frequencies and increase of compressor and engine as a whole service life.;23 cl, 8 dwg
