    摘要： A seal structure that achieves a thick abradable film, thereby improving sealing performance, is provided. A seal structure is provided with at least one fin that projects in a ring-shape from a circumferential surface of a rotating shaft and that is provided along an axial direction and a seal member having a ring-shaped sealing surface opposed to the fin, and on which an abradable layer is formed by thermally spraying abradable material onto the sealing surface, the seal structure is provided with tapered portions inclined in a radial direction at end portions of the sealing surface in the axial direction.

    摘要： A segmented floating seal assembly used in a gas turbine engine to seal a rotary shaft. The segmented seal is made from a fiber reinforced ceramic matrix composite (FRCMC) material having a polymer-derived pre-ceramic resin in its ceramic state, fibers of Nextel, and a filler material. The seal segments are secured to respective support plates, and the support plates are each biased by a spring member secured to a support ring mounted in the engine. The material in the seal segments are resistive to very high temperatures, are not brittle, allow little flow across the seal face, and durable. The segmented seal includes holes in either the segments or the rotary shaft in which pressurized air is supplied to the seal interface to form an air cushion on which the seal segments can float.

    摘要： Repair or replacement of a projection such as a labyrinth seal tooth of a metal having relatively poor weldability characteristics is accomplished by removing a portion or possibly all of the seal tooth down to a pedestal and then metallurgically bonding as by fusing to the pedestal a second metal characterized as having good weldability characteristics when diluted with the first metal, and age hardenable with an aging heat treatment with which the first metal also is age hardenable.

The sealing element, if installed in the sealing system according to the intended use, can be rotated around a rotational axis of the turbomachine. The sealing element comprises a ring-shaped sealing lip that has a central point through which the rotational axis extends if the sealing element is installed in the sealing system according to the intended use, wherein the sealing lip has at least one recess, and at least one rubbing element that is arranged at the sealing lip, wherein the at least one rubbing element is arranged inside the at least one recess and projects at least partially beyond the outer contour of the sealing lip in the radial and/or the axial direction with respect to the rotational axis. The at least one rubbing element has a plurality of layers of a rubbing material.
