Abstract

Изобретение относитс  к машиностроению и предназначено дл  гашени  колебаний роторов турбомашин. Целью изобретени   вл етс  повышение эффективности демпфировани . На пористых выступах 9 и 10, напыленных из твердосплавного материала, при колебани х втулки вибратора 3 дросселируетс  выдавливаема  из демпферного зазора 5 смазка, что позвол ет эффективно рассеивать энергию колебаний. Изобретение позвол ет повысить надежность и расширить диапазон демпфировани . 2 ил.The invention relates to mechanical engineering and is intended to dampen the vibrations of rotors of turbomachines. The aim of the invention is to increase the efficiency of damping. On porous protrusions 9 and 10, sprayed from a carbide material, with vibrations of the sleeve of the vibrator 3, the lubricant is squeezed out of the damping gap 5, which effectively dissipates the oscillation energy. The invention makes it possible to increase reliability and extend the range of damping. 2 Il.
