摘要： A metallic sealing assembly between a rotating shaft and a fixed frame comprises: a flexible metallic seal having two tori, inner and outer, that are concentric and of different average diameters, comprising a metal envelope which encases and holds the inner and outer tori; a shaft rotating about an axis of rotation, comprising an annular shoulder against which the seal comes to press; a counter-face, comprising a contact face against which the seal comes to press; a wedge block positioned around the rotating shaft such that the seal is held between the wedge block and the contact face, the wedge block mounted to slide on the rotating shaft; a metal part which forms a cap through which the rotating shaft passes and which is secured to the frame and/or to the counter-face, the rotating shaft being free to rotate with respect to the cap and axially secured to the cap.

摘要： The seal comprises a casing made of two portions (1, 2) crimped into one another with an accurate hermetic position adjustment at interfaces (15, 6b) and a composite structure comprising inside the casing an advantageously flexible and resilient core (24) and a winding (20) of brush bristles. This structure directly extends facing internal faces (9, 10) facing each other in the casing, which compresses the same and has an arcuate shape having a slightly higher radius of curvature. The composite structure is held at an accurate position, firmly but free of constraint.
摘要翻译： 密封件包括由两个彼此压接的部分（1,2）制成的壳体，其中在界面（15,6b）处具有准确的密封位置调整和复合结构，该复合结构在壳体的内部具有有利的柔性和弹性的芯部（24）和 卷（20）的刷毛。 这种结构直接在壳体内面向彼此面对的内表面（9,10），该内表面（9,10）将其压缩并具有稍高的曲率半径的弓形。 复合结构牢固但没有限制地保持在准确的位置。
