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.

Abstract translation: 密封环组件包括从第二密封环轴向设置的第一密封环。 第一密封环具有与第二密封环的轴向面相对的轴向面。 径向油通道限定在两个轴向面之间。 两个密封环都具有构造成接触弹簧的锥形表面。 弹簧通过锥形表面使密封圈偏离彼此。 两个密封环设置在径向向内定向的通道中。 至少一个密封环具有延伸超过轴向面的多个突起。 突起被构造成产生通道以允许油流过通道并且允许至少一个密封环通过减小轴向面之间的静摩擦而移动到期望的位置。

Abstract: A seal ring assembly for a rotor shaft includes a seal casing defining a radially inwardly directed channel. The seal ring is disposed in the radially inwardly directed channel of the seal casing. The seal ring is resiliently joined about the shaft to form a seal, and the seal ring comprises an electrically insulating or dissipative material or a non-metallic material.
