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.
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.
3. Вращающийся механизм по п.2, в котором вращающийся механизм является паровой турбиной.
4. Вращающийся механизм по п.2, в котором вращающийся механизм является газовой турбиной.
