Abstract

1. Гидродинамический демпфер опоры ротора турбомашины, содержащий внутреннюю и наружную втулки, расположенные с кольцевым зазором, сообщенным каналами с полостью высокого давления гидросистемы, и фиксатор взаимного смещения втулок в окружном направлении, причем наружная втулка установлена неподвижно, а внутренняя - с возможностью радиального перемещения, отличающийся тем, что, с целью повышения надежности работы, фиксатор выполнен в виде кольцевой шайбы, расположенной со стороны торцов втулок, соединенной с ними и установленной с возможностью перемещения в радиальном направлении, перпендикулярном направлению перемещения внутренней втулки.2. Демпфер по п.1, отличающийся тем, что кольцевая шайба снабжена двумя диаметрально расположенными торцовыми радиальными выступами и размещенными перпендикулярно им на внутренней поверхности шайбы двумя плоскими участками, а наружная и внутренняя втулки - соответственно пазами и лысками, ответными выступам и плоским участкам.1. Hydrodynamic damper support rotor of the turbomachine, containing the inner and outer bushings, located with an annular gap, communicated channels with a high pressure cavity of the hydraulic system, and a latch of mutual displacement of the bushings in the circumferential direction, and the outer sleeve is fixed, and the inner - with the possibility of radial movement, characterized in that, in order to increase reliability of operation, the retainer is made in the form of an annular washer located on the side of the ends of the sleeves connected to them and installed with the movement in the radial direction, perpendicular to the direction of movement of the inner sleeve. A damper according to claim 1, characterized in that the annular washer is provided with two diametrically located frontal radial protrusions and placed perpendicular to them on the inner surface of the washer with two flat sections, and the outer and inner sleeves respectively grooves and flatheads, counter projections and flat sections.
