摘要

An arrangement having a gas seal, a stator and a rotor extending along an axis for sealing a sealing gap between the rotor and the stator, including a rotating rotor sealing ring and a static stator sealing ring, comprising a rotating fixing element, which axially fixes the rotor sealing ring at the rotor is provided.

主权项

1. An arrangement with a gas seal, a stator and a rotor which extends along an axis for sealing a sealing gap between the rotor and the stator, comprising;
a rotating rotor sealing ring; a static stator sealing ring; and a rotating fastening element that fixes the rotating rotor sealing ring axially on the rotor, the fastening element extending at least over a part of a circumference in a circumferential direction, and being arranged at least partially in a gap of a radial gap height that extends axially and in the circumferential direction between the rotor and the rotating rotor sealing ring, the gap being defined on a side of the rotating rotor sealing ring by a sealing ring surface and on a side of the rotor by a rotor surface, the sealing ring surface having a first depression and the rotor surface having a second depression; wherein the fastening element is arranged in the first depression and partially in the second depression, in such a way that an axial relative movement beyond a setpoint position range between the rotating rotor sealing ring and the rotor is possible only via a radial deformation of the fastening element.
