Abstract
A seal assembly includes a seal formed of a carbon material, and received within an inner bore in a carrier. The seal extends for 360 degrees relative to a central axis of a bore in the seal. A groove is formed in an outer periphery of the seal and an inner periphery of the carrier. A wire is received within the groove to lock the seal within the carrier. A gas turbine engine and a method are also disclosed.
Claims23
A seal assembly comprising:
- a seal formed of a carbon material, and received within an inner bore in a carrier, said seal extending for 360 degrees relative to a central axis of a bore in the seal;
- a groove formed in both an outer periphery of the seal and an inner periphery of the carrier;
- a wire received within the groove to lock the seal within the carrier;
- and
- wherein a diameter of the wire is less than a combined width of the groove in the outer periphery of the seal and the groove in the inner periphery of the carrier such that there is clearance.

A gas turbine engine comprising:
- a shaft for rotation about an axis, and said shaft rotating with a rotating seal face, and a seal assembly sealing against the rotating seal face;
- and
- the seal assembly having a seal body formed of a carbon material, and received within an inner bore in a carrier, said seal extending for 360 degrees relative to a rotational axis of the shaft and a groove formed in both an outer periphery of the seal and an inner periphery of the carrier and a wire received within the groove to lock the seal within the carrier;
- and
- wherein a diameter of the wire is less than a combined width of the groove in the outer periphery of the seal and a groove in the inner periphery of the carrier such that there is clearance.

A method of assembling a seal comprising the steps of:
- inserting a seal body formed of a carbon material into a bore in a carrier assembly, each of an outer periphery of the seal and an inner periphery of the carrier including a groove;
- moving a wire through an opening in the carrier into the groove in the carrier and the seal body to secure the seal to the carrier;
- and
- wherein a diameter of the wire is less than a combined width of the groove in an outer periphery of the seal and the groove in an inner periphery of the carrier such that there is clearance .
