Abstract: The invention is directed to a guide vane device for a guide vane adjustment of a turbomachine, comprising a guide vane, which has a shaft extending along an adjustment axis of the guide vane, as well as an adjusting lever, which forms a connecting element for connection to an outer end of the shaft, wherein, at its outer end, the shaft has a three-dimensional front surface with at least one beveled region, the connecting element surrounds, at least in sections, the outer end of the shaft in a sleeve-like manner and is joined to the outer end in a form-fitting manner, and the guide vane device forms an interference fit between the connecting element and the outer end of the shaft.

Abstract: The invention relates to a guide vane assembly as well as to a method for mounting a guide vane assembly of a turbomachine, including a number of adjustable guide vanes, the guide vane platform of which has a guide vane journal that is mounted in a receiving opening of a housing of the turbomachine, wherein a guide vane head of the guide vane has a bearing pin, which is mounted on an inner ring arranged on a rotor of the turbomachine. In the method, a guide vane journal, which is arranged on a guide vane platform of a guide vane, is brought into a receiving opening of a housing, which is arranged radially with respect to a rotor axis of the turbomachine, and an inner ring is provided on a rotor of the turbomachine.

Abstract: The invention relates to a sealing arrangement for a non-hermetic seal of a gap (11) between a stator and a rotor with a brush seal (13), wherein the brush seal (13) has a bristle package (14) with several bristles (15), the bristles are wound about a core element (16) and fixed to the core element (16), wherein the brush seal (13) is disposed at least sectionally in an accommodating space, which is bounded by a supporting element (18) and a covering element (19), and wherein the bristles (15) have sealing bristle sections (21), which are at an angle to the bristle shafts (20) and the ends of which run against a sealing surface (22) of the rotor (12). According to the invention, the covering element (19) has a support surface (23) at an end adjacent to the sealing bristle sections (21), wherein the supporting surface (23) contacts the bristle shafts (20) in a defined, locally limited region, so that the radial mobility of the sealing bristle sections (21) is limited in the direction of the rotor (12).

Abstract: 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.

Abstract: A brush seal assembly is provided for sealing components which move relative to one another. One of the components includes a recess or groove for accommodating a clamping sleeve which supports bristles. A support plate which is formed separately from the component and the clamping sleeve is pressed into the recess and abuts the recess wall surfaces and the clamping sleeve to hold the same in a predetermined working position.

Abstract: An arrangement for a non-hermetic seal between a stator and a rotor of a turbomachine in the root region of guide blades belonging to the stator. The arrangement includes a brush sealing ring which is mounted on the guide blades via a spoke centering means and whose bristles together with a rotating sealing surface form a fluid barrier which is permeable in a defined manner. On the sealing side of lower pressure, a supporting ring for the bristles is arranged at a slight distance from the rotating sealing surface, and this supporting ring is integrally connected to the guide blade roots and can be segmented by parting seams. The spoke centering means is permeable to pressure, as a result of which the brush sealing ring is pressure-relieved axially, with the exception of the bristle area between the sealing surface and supporting ring.
