CIRCUMFERENTIAL SEAL WITH CERAMIC ROTOR

摘要

A circumferential seal for sealing (29) between a rotating shaft (12) and a stationary housing (34) circumscribing the shaft (12). The seal (29) comprises a stator (31) mounted to said housing (34) and having a radially inward facing carbon (36) portion and a rotor with a ceramic sealing (49) member having a radially outward facing surface in rubbing contact with said carbon portion (36). The rotor also includes a metal clamping means (52) for mounting the ceramic sealing member (49) to the shaft (12). The clamping means (52) includes an axial flexible clamping member, and a radial flexible clamping member that together clamp onto a mounting flange (58) of the ceramic sealing member (49) when exposed to the compressive force of a lockup assembly.
