RADIAL SEAL ARRANGEMENT

A seal assembly (70) includes a rotating seal runner (74) having an outer radial surface (80), and one or more rotationally stationary seal rings (76) located radially outboard of the seal runner (74). Each seal ring (76) has an inner radial surface (82), with the inner radial surface (82) and the o...

Beschreibung
Zusammenfassung:	A seal assembly (70) includes a rotating seal runner (74) having an outer radial surface (80), and one or more rotationally stationary seal rings (76) located radially outboard of the seal runner (74). Each seal ring (76) has an inner radial surface (82), with the inner radial surface (82) and the outer radial surface (80) defining a sealing interface (84) therebetween. An axially extending shape (94) of the inner radial surface (82) is selected utilizing a predicted shape (90) of the outer radial surface (80) at a selected operating condition of the seal assembly (70).
