摘要： A shaft seal structure capable of preventing a seal body of the shaft seal structure of a rotation body from being held in an inclined posture even when the seal body is inclined is provided. It includes, an accommodation body (9), a seal body (12) including thin plate seal pieces (20), and a plate body (17) covering one end in the axial direction (20d) of the seal body (12). A recessed portion (31) recessing in the axis direction, and a protruding portion projecting to the other side from the recessed portion (31) are formed on one of the plate surface (17c) of the plate body (17) and the inner wall surface (9e) of the accommodation body (9). When the protruding portion abuts the other side and a pocket (X), the recessed portion(31) communicates with the pocket (X) and the fluid low pressure region.

摘要： The purpose of the present invention is to provide a shaft seal mechanism that, even if pressing force is applied to thin-plate seal pieces, can suppress deformation due to the pressing force and prevent abrasion due to contact with a rotating shaft in the thin-plate seal pieces. In order to achieve the foregoing, a shaft seal mechanism (11) that blocks a fluid (G) flowing within a ring-shaped space (14) is equipped with: a ring-shaped seal housing (21) disposed on a fixed section (12); a plurality of thin-plate seal pieces (22) that are secured to the seal housing (21), are in sliding contact with a rotating shaft (13), and are layered in a ring shape; a ring-shaped high-pressure-side plate (25) that forms a high-pressure-side gap (´H) between itself and the seal housing (21); a ring-shaped low-pressure-side plate (26) that forms a low-pressure-side gap (´L) between the seal housing (21) and the thin-plate seal pieces (22); stepped sections (31, 32) that are formed on side edge sections (22c, 22d) of the thin-plate seal pieces (22); and locking sections (25b, 26b) that lock the stepped sections (31, 32).

摘要： Provided is a shaft sealing mechanism that, by making the pressure of fluid that flows between thin-plate seal pieces uniform, can eliminate the fluid pressure difference that acts on an upper surface and a lower surface of the thin-plate seal pieces and suppress vibration of the thin-plate seal pieces. A shaft sealing mechanism (11) that partitions an annular space (14) that is formed between a fixed part (12) and a rotating shaft (13) into a high-pressure-side region and a low-pressure-side region, that obstructs the flow of a fluid (G), and that is provided with: a plurality of annularly laminated thin-plate seal pieces (22) that are fixed to an annular seal housing (21) that is provided to the fixed part (12) and are in sliding contact with the rotating shaft (13) ; and an annular low-pressure-side plate (26) that is sandwiched and held such that a low-pressure-side gap (´L) is formed between the seal housing (21) and a low-pressure-side side edge part (22d) of the thin-plate seal pieces (22). The thin-plate seal pieces (22) have pressure-conduction holes (31) that are formed further to the inside in the radial direction of the rotating shaft than an inner-circumferential-side tip part (26a) of the low-pressure-side plate (26).

摘要： A shaft sealing device (10) includes a plurality of leaves (20) that is arranged in a periphery of a rotating shaft (50) and divides a space around the rotating shaft into two spaces in an axial direction of the rotating shaft, and a side seal plate that is arranged on one side of the leaf in the axial direction and has an opposite surface facing a side end on one side of the leaf. The leaf and/or the side seal plate has a friction reducing portion for reducing a friction force between the opposite surface and a surface of the side end.

摘要： The present invention is to ensure degrees of freedom of bristles toward upstream and prevent their flapping at the same time, while also increasing the rigidity of bristles in the direction of pressure difference between the high-pressure side and low-pressure side to reduce the wear of bristles. Provided is a brush seal having: a bristle part formed by multiple bristles attached to a stationary part between the stationary part and a rotational part that undergo relative motion by maintaining a space in between; and a back plate attached adjacent to the bristle part on its low-pressure side to restrict the movement of the bristle part, for the purpose of sealing the fluid flowing between the stationary part and rotational part; wherein such brush seal is characterized in that the bristle part formed by multiple bristles is such that the multiple bristles arranged in the flowing direction of fluid are mutually fixed between the base end and free end to form planar bristles and these planar bristles are arranged continuously in layers in a circumferential direction to form the bristle part.
摘要翻译：本发明是为了确保刷毛向上游方向的自由度并同时防止它们的扑动，同时还增加了刷高度在高压侧和低压侧之间的压差方向上的刚度，以减少磨损的鬃毛。提供一种刷密封件，其具有：刷毛部，其通过多个刷毛形成，所述刷毛附接到所述固定部分与通过保持其间的空间而经历相对运动的旋转部件之间的静止部分; 以及在其低压侧附近与刷毛部分相邻的背板，以限制刷毛部分的运动，用于密封在固定部分和旋转部分之间流动的流体; 其特征在于，由多个刷毛形成的刷毛部分使得沿着流体的流动方向布置的多个刷毛相互固定在基端和自由端之间以形成平面刷毛，并且这些平面刷毛连续布置在圆周方向上形成刷毛部分。
