摘要： A leaf seal for sealing a shaft rotating about an axis, in particular in a gas turbine, includes a plurality of spaced-apart leaves arranged in a concentric circle around the axis and fixed in position by brazing, the leaves having surfaces oriented essentially parallel to the axis. The leaves are brazed to one another via intermediate spacers made of a brazing foil, so that a brazed joint is produced by brazing alloy from the brazing foils. The brazing temperature may be set to an optimum value just above the solidus temperature of the brazing foil, at which partial melting of the brazing foil occurs and penetration of liquid brazing alloy into the gap between the leaves is avoided.

摘要： A method of processing seals (20), like leaf seals, in which seals (20) an annular gap, formed between two coaxial, cylindrical surfaces, is sealed off in the axial direction by a multiplicity of individual, thin sealing elements (22; 22a, b) which, with an orientation deviating from the radial direction, extend transversely through the gap and are fixed at their end assigned to the one cylindrical surface and bear loosely with the other, free end against the other cylindrical surface. An improvement in the sealing geometry is achieved in a simple manner in that, for the uniform orientation of the free ends of the sealing elements (22; 22a, b), in a first step, the sealing elements (22, 22a, b) are brought to bear with their free ends against a coaxial cylindrical surface having a predetermined diameter (D) in such a way that they are subjected to a bending stress, and in that, in a second step, the sealing elements (22; 22a, b) subjected to the bending stress are subjected to a heat treatment in such a way that the bending stress is completely removed.
摘要翻译：一种处理密封件（20）的方法，如叶片密封件，其中形成在两个同轴的圆柱形表面之间的环形间隙的密封件（20）通过多个单独的薄密封元件（22; 22）在轴向上被密封。如图22a，b）所示，具有偏离径向方向的方向横向延伸穿过间隙，并且在它们的端部被固定到一个圆柱形表面，并松开地与另一个自由端相对于另一个圆柱形表面承载。密封几何形状的改进以简单的方式实现，因为对于密封元件（22; 22a，b）的自由端的均匀取向，在第一步骤中，密封元件（22,22a， b）以其自由端承载在具有预定直径（D）的同轴圆柱形表面上，使得它们受到弯曲应力，并且在第二步骤中，密封元件（22; 对经受弯曲应力的弯曲应力进行热处理，使得弯曲应力被完全去除。

摘要： A leaf seal for sealing a shaft rotating about an axis, in particular in a gas turbine, includes a plurality of spaced-apart leaves disposed in a concentric circle around the axis and fixed in position. Each of the leaves includes a surface oriented essentially parallel to the axis and an integrally formed element configured to position and retain the leaves in the leaf seal.

摘要： In a process for producing leaves (20, 20′) for a leaf seal, in particular as a seal for a gas turbine, which leaves (20, 20′) are laterally delimited by a peripheral edge contour and have regions of different thicknesses (d1, d2), a simplification, without sacrificing precision, is achieved by virtue of the edge contour of the leaves (20, 20′) being cut out of a metal sheet (28) by an etching process and the regions of different thicknesses (d1, d2) also being produced simultaneously as part of the etching process.

摘要： A leaf seal for sealing a shaft rotating about an axis, in particular in a gas turbine, includes a multiplicity of spaced-apart leaves (26) which are arranged in a concentric circle around the axis and are fixed in their position by welded connections produced by electron beam welding, the leaves (26), with their surfaces, being oriented essentially parallel to the axis. The welded connections of the leaves are improved by the leaves (26) being designed in such a way and being arranged in the leaf seal in such a way that they abut against one another at the side edges directly or via intermediate spacers (27) along at least one contact line (36) extending over a plurality of leaves (26), and by the welded connections being designed as welds directed along the at least one contact line (36) and oriented in axial direction.
