Abstract:
A seal ring assembly includes a first seal ring axially disposed from a second seal ring. The first seal ring has an axial face opposing an axial face of the second seal ring. A radial oil channel is defined between the two axial faces. Both seal rings have a tapered surface configured to contact a spring. The spring biases the seal rings away from each other via the tapered surface. Both seal rings are disposed in a radially inwardly directed channel. At least one of the seal rings have a plurality of protrusions that extend beyond the axial face. The protrusions are configured to create a passageway to allow oil to flow through the passageway and to allow at least one of the seal rings to move into a desired position by reducing static friction between the axial faces.
