Abstract

En forankringsanordning (400) for å befeste en pakningsenhet i en f6ring har en skjør ring (410) med en mengde gripere (415) på en ytre omkrets, idet en første ende (412) av den skjøre ring har en mengde omkretsmessige spalter (41 1) i innbyrdes avstand, og en ekspansjonsring (420) med en mengde tårn (421) konfigurert for å gå i inngrep med spaltene i den første ende av den skjøre ring. En fremgangsmåte for å befeste en pakningsenhet i en f6ring omfatter at en mengde buede segmenter (431) i en segmentert ring (430) går i inngrep med en mengde spalter i en første ende (412) av en skjør ring (410), en mengde tårn (421) på en ekspansjonsring (420) går i inngrep med en mengde spalter i en andre ende (413) av den skjøre ring og ekspansjonsringen forflyttes i aksial retning mot den skjøre ring og splitter den skjøre ring i en mengde kilesegmenter (414) for derved radialt å utvide mengden av kilesegmenter og den segmenterte ring inn i f6ringen.
