Description

(54) УПЛОТНЕНИЕ ВРЛЩЛЮЦЕГОСЯ ВЛЛЛ(54) SEAL OF RALLY WLL

втулкой и кольцом демпфирует его радиальные высокочас.тотные колебани .the sleeve and the ring damps its radial high-hourly oscillations.

Дополнительна же центрирующа сила возникает благодар расположению выходов каналов на поверхности кольца - при радиальном смещении вала давление в зоне расположенных в изменившемс зазоре выходов каналов на внут-, реннюю поверхность кольца- возрастает и по каналам передаетс на смещенные под углом на 180 выходы на внешнюю поверхность кольца,в результате чего возникает дополнительна гидростатическа сила,перемещающа кольцо в сторону движени вала и исключающа их контактAdditional centering force arises due to the location of the channel outlets on the ring surface — with radial displacement of the shaft, the pressure in the zone of the channel outlets located in the changed clearance of the channels on the inner, recessed surface of the ring increases and through the channels is transmitted to the outwardly displaced rings As a result, an additional hydrostatic force arises, moving the ring in the direction of the shaft movement and eliminating their contact.

Таким образом, в предлагаемом устройстве обеспечиваетс центрирование кольца и демпфирование его колебаний.Thus, in the proposed device, the ring is centered and its oscillation is damped.

Claims

Claims A seal of a rotating shaft comprising an unloaded floating ring with channels for hydrodynamic weighing of a ring relative to a shaft, characterized in that, in order to improve the centering of the ring and damping vibrations, concentric with a ring with a gap commensurate with the gap between the ring and the shaft, a floating floating ring is fitted with a gap with a gap comparable to the gap between the ring and the shaft, a floating floating ring is installed, with a floating ring that is comparable to the gap between the ring and the shaft, a floating ring is installed, with a floating ring that is comparable to the gap between the ring and the shaft, a floating floating ring is installed, with a gap floating in proportion to the gap between the ring and the shaft. and the outlet of each channel to the outer surface of the ring is located in the gap between the ring and the sleeve in the zone of equal or lower pressure than the pressure at the outlet an inner surface and offset relative to the latter by 180 °.
