Sealing arrangement for sealing a gap between two components which can rotate in relation to each other about a common rotational axis
View Patent ↗A sealing arrangement for sealing a gap between two components which can move rotationally with respect to one another about a common axis of rotation, having a brush seal on a first component which interacts with a sealing surface of the second component. The sealing surface is conical in form, with at least one component being axially displaceable and adjustable with respect to the other component in order to reduce the gap between the brush seal and the second component.
1. A sealing arrangement for sealing a gap between two components which can move rotationally with respect to one another about a common axis of rotation, having a brush seal which is arranged fixedly in the first component of the two components and interacts with a sealing surface of the second component, wherein the sealing surface is a surface of a shaft end of the second component which is conical in form, with the first component being axially displaceable and adjustable with respect to the second component, the first component being disposed axially adjacent to the second component shaft end, and means for axial displacement and adjustment being provided between the first component and a casing surrounding the first component, such that when the first component is axially displaced, the brush seal is axially displaced relative to the second component while remaining in sealing contact with the second component sealing surface.
2. The sealing arrangement as claimed in claim 1 , wherein the means for axial displacement and adjustment comprise a sliding seat, an adjustment nut which is fitted into the casing and a displacement screw thread cut into the first component.
3. The sealing arrangement as claimed in claim 1 , wherein the axial displacement is controlled by at least one threaded connection between one of the components and a casing which receives said component.
4. The sealing arrangement as claimed in claim 1 , wherein the axial displacement is controlled by at least one of a mechanical and a hydraulic adjuster.
