Abstract

En gass-sperrende kontaktløs tetningsanordning lor en aksel (1) omfatter en tetningshylse (2) samt en statortetningsring (3) anordnet i hylsen og en rotortetningsring (4) fast anordnet på akselen. De to tetningsringer (3, 4) arbeider med sine tetningssideflater (3a, 4a) mot hverandre med mellomkobl- ing av en gass-sperre i en tetningsspalt (6). Statortetnings- ringen oppviser overfor en sylinderdel på akselsiden av tetningshylsen i driftstilstand og under forut fastlagt driftstrykkforskjell en funksjonsringspalt (F), som er avtettet av en 0-ring (11) av gummi eller plastmaterial og trykkes i retning mot gass-sperren med en trykk-kraft fastlagt av en trykkfjer (7). Både rotor- og statortetningsring består av et hardt tetningsmaterial med høy varmeledningsevne samt høy elastisitetsmodul og hardhet, statortetningsringen oppviser så stort flatetreghetsmoment at spaltetykkelsen av funksjonsringspalten (F) mellom tetningshylsens sylinderdel på akselsiden og statortetningsringen i driftstilstand og under driftstrykkforskjell i praksis stemmer overens med den konstruktivt forut bestemte spaltetykkelse av monteringsrings- palten mellom sylinderdel og statortetningsring i alle drifts- tilstander samt er mindre enn 0,4 mm, og fortrinnsvis mindre enn 0,3 mm. Den avtettende 0-ring (11) er i tillegg utfart som utligningssentreringsring for statortetningsringen (3) samt oppviser også en materialhardhet som er større enn ekstrusjons-grenseverdien med hensyn til materialhardhet ved den angitte spaltebredde og den forut fastlagte driftstrykk- forskjell, samt mindre enn en materialhardhet på 90 Shore A i henhold til DIN 53 505.
