摘要： An intershaft seal assembly (30) for use between an inner shaft (32) and an outer shaft (31) within a turbine engine is presented. The seal assembly (30) includes a sealing ring (33), centrifugal retaining plates (102), and end rings (37, 38). The sealing ring (33) further includes a plurality of asymmetric ring segments (34) whereby each asymmetric ring segment (34) further includes a vertical flange (46) and horizontal flanges (47) extending from the vertical flange (46) in a non-symmetric arrangement. At least one slot (104) is disposed along each horizontal flange (47). The sealing ring (33) is interposed between the centrifugal retaining plates (102). Each centrifugal retaining plate (102) includes a plurality of tabs (103) extending therefrom. Each tab (103) is engaged by one slot (104). The sealing ring (33) and the centrifugal retaining plates (102) are interposed between the end rings (37, 38). Each centrifugal retaining plate (102) is directly interposed between one horizontal flange (47) and one end ring (37, 38). The vertical flange (46) extends from between the end rings (37, 38) in the direction of the outer shaft (31). A non-contact seal is formed between an outer sealing surface (62) along the vertical flange (46) and an inner sealing surface (63) along the outer shaft (31).

摘要： An intershaft seal assembly (30) for use between an inner shaft (32) and an outer shaft (31) rotatable within a turbine engine is presented. The seal assembly (30) includes a sealing ring (33), an inner ring (39), and a pair of end rings (37, 38). The sealing ring (33) further includes a plurality of asymmetric ring segments (34) whereby each asymmetric ring segment (34) further includes a vertical flange (46) and a pair of horizontal flanges (47) extending from the vertical flange (46) in a non-symmetric arrangement. The non- symmetric seal geometry provides an axial force balance thereby reducing wear and increasing seal life. The sealing ring (33) is disposed about the inner ring (39). The inner ring (39) includes a plurality of ridges (43) that engage the asymmetric ring segments (34) so as to prevent rotation of the asymmetric ring segments (34) with respect to the inner shaft (32). The end rings (37, 38) are disposed about the sealing ring (33) and the inner ring (39). The horizontal flanges (47) separately contact the end rings (37, 38) so that the vertical flange (46) extends from and between the end rings (37, 38) in the direction of the outer shaft (31). A non-contact seal is formed between an outer sealing surface (62) along the vertical flange (46) and an inner sealing surface (63) along the outer shaft (31).

摘要： An improved air-riding seal system (1) for turbine engines is presented. The seal system (1) includes a movable primary seal assembly (2), a stationary secondary seal assembly, and at least one structure to increase the stiffness of a thin film between the primary seal and a rotating component. The primary seal assembly (2) includes an annular seal ring (23) and an arcuate support arm (25). The annular seal ring (23) has a cross section that is substantially L-shaped and a surface with a step face (4) and a circumferential dam (3). The arcuate support arm (25) has a tooth (27) at one end adjacent to an outermost circumferential surface (26) along the seal runner (19), which could include an optional notch (37). The tooth (27) and outermost circumferential surface (26) are separated by a gap (28). The secondary seal ring (6) is disposed between and contacts the primary seal assembly (2) and housing structure (5) so as to form a bore seal and a face seal therewith. A plurality of radial dams (35) disposed along the surface in an outward radial arrangement from the circumferential dam (3) are provided to improve the stiffness of the thin film. Features of the invention allow for higher operating speeds.
