INCREASED WEAR-LIFE MECHANICAL FACE SEAL ANTI-ROTATION SYSTEM |
摘要 |
One or more stator seal assemblies are mounted in the housing of a rotating machine such as, for example, an air turbine starter for a gas turbine engine, and surround a rotating shaft. The seal assemblies each include a seal case and a seal. The seal has a face that engages an axial face of a face seal rotor to form a seal. One or more anti-rotation tabs in the seal case engage anti-rotation notches formed in the peripheral surface of the seal. The anti-rotation notches each include substantially arcuate sections formed in notch end surfaces. The arcuate sections increase the amount of wear in the notches that can be tolerated before a potential seal lock-up, thus increasing seal assembly lifetime. |
