    • A circumferential seal for sealing between a rotating shaft and a stationary housing circumscribing the shaft. The seal comprises a stator mounted to said housing and having a radially inward facing carbon portion and a rotor with a ceramic sealing member having a radially outward facing surface in rubbing contact with said carbon portion. The rotor also includes a metal clamping means for mounting the ceramic sealing member to the shaft. The clamping means includes an axial flexible clamping member, and a radial flexible clamping member that together clamp onto a mounting flange of the ceramic sealing member when exposed to the compressive force of a lockup assembly.
    • 用于在旋转轴和限定轴之间的固定壳体之间进行密封的周向密封。 密封件包括安装到所述壳体并具有径向向内的碳部分的定子和具有陶瓷密封构件的转子,所述陶瓷密封构件具有与所述碳部分摩擦接触的径向向外的表面。 转子还包括用于将陶瓷密封构件安装到轴上的金属夹紧装置。 夹持装置包括轴向柔性夹紧构件和径向柔性夹紧构件,当暴露于锁定组件的压缩力时,它们一起夹紧在陶瓷密封构件的安装凸缘上。
