Claims (8)

1. Кольцевой сальник турбины, предназначенный для размещения в турбине между вращающимся узлом, имеющим ось вращения, и корпусом турбины вокруг указанной оси, который включает в себя: множество дугообразных несущих сегментов сальника, причем каждый из несущих сегментов сальника содержит истираемую часть, где истираемая часть скреплена с каждым из дугообразных несущих сегментов сальника, и по меньшей мере одну пружину, расположенную таким образом, чтобы прилагать усилие для поддерживания размещения дугообразных несущих сегментов сальника рядом с вращающимся узлом во время вращения.1. An annular turbine seal, intended for placement in a turbine between a rotating assembly having an axis of rotation, and a turbine casing around the specified axis, which includes: a plurality of arcuate bearing segments of the stuffing box, each of the bearing segments of the stuffing box containing an abradable part, where the abrasive part bonded to each of the arcuate bearing segments of the oil seal, and at least one spring positioned so as to exert force to maintain placement of the arcuate bearing segments of the oil seal next to the rotating assembly during rotation. 2. Вращающийся механизм, имеющий множество ступеней, который включает в себя: вращающийся узел, неподвижный узел, охватывающий вращающийся узел, причем узлы размещаются на общей оси, и множество дугообразных несущих сегментов сальника, размещенных между вращающимся узлом и неподвижным узлом, причем каждый из несущих сегментов сальника содержит истираемую часть и, по меньшей мере, одну пружину, расположенную таким образом, чтобы прилагать усилие для поддерживания размещения дугообразных несущих сегментов сальника рядом с вращающимся узлом.2. A rotating mechanism having a plurality of steps, which includes: a rotating assembly, a fixed assembly covering the rotating assembly, the assemblies being placed on a common axis, and a plurality of arcuate bearing segments of the stuffing box located between the rotating assembly and the stationary assembly, each of which the gland segments contains an abradable part and at least one spring located in such a way as to exert a force to maintain the placement of the arcuate bearing segments of the gland next to the rotating unit ohm 3.
