摘要： The present disclosure relates to sealing systems for bearing compartments. In one embodiment, a sealing system includes a runner configured to extend circumferentially around a rotating component, the runner is formed of a material with low radial thermal growth and is configured to tit to the rotating component to remove heat away from the runner. The runner can include an outer surface configured to provide passive cooling for the runner in the bearing compartment. The sealing system can also include a seal configured to operate with the runner, wherein the seal includes a clearance seal on an air side of the runner. The runner can be configured to operate without direct oil cooling.

摘要： A face seal comprising an annular carbon stator having a flat sealing surface in rubbing contact with a flat sealing surface of an annular metallic rotor. The rotor has a head portion connected to a base portion by a neck portion, that is disposed on the same side of the rotor as the rotor's flat sealing surface. The neck portion has two straight radial surfaces, and is disposed on the same side of the rotor as the rotor's flat sealing surface. The formation of adverse thermal gradients within the rotor can be avoided by adjusting the axial thickness of the neck portion, thereby preventing coning of the rotor.

摘要： A face seal includes an annular carbon stator having a flat surface in rubbing contact with the flat surface of a composite annular rotor. The annular rotor has a head portion and a base portion. Embedded in the head portion are high thermal conductivity graphite fibers that are oriented to maximize heat dissipation. Incorporation of graphite fibers makes the rotor resistant to time-dependent creep deformation, thus preserving sealing integrity.

摘要： A runner assembly for a circumferential seal assembly includes a runner defined about an axis. The runner has an inwardly extending runner mounting flange. A radially flexible clamp is engaged with the inwardly extending mounting flange. An axial spring is trapped between an axial retainer and the runner. The runner, the radially flexible clamp, the axial spring, and the axial retainer are co-rotatable about the axis. The axial retainer is radially inline with the runner and spaced from a radially inner surface of the runner such that there is a radial gap between the axial retainer and the radially inner surface of the runner permitting radial movement of the runner.

摘要： Disclosed is an oil film cooled face seal that is comprised of an annular stator having a flat surface in rubbing contact with the flat sealing surface of a rotor. The rotor has a flange portion extending radially from a base portion. The base portion has a plurality of holes extending radially therethrough in fluid communication with a source of cooling oil. One side of the flange portion comprises the flat sealing surface. The opposite side, or backface, has a plurality of external radially spaced apart annular grooves criss-crossing a plurality of external circumferentially spaced apart substantially radial grooves. Each of the radial grooves is aligned with and in fluid communication with a corresponding hole in the base portion, and extends fully across the backface. Upon rotation of the rotor, centrifugal force causes the cooling oil to flow from the cooling oil source, through the hole, through the radial groove wherein aerodynamic force causes a portion of the oil to flow across the backface and into the annular grooves, thereby convectively cooling the rotor.
