Abstract

Foreliggende oppfinnelse angår en aktuator for lineær bevegelse, omfat- tende en motor (5) forsynt med en roterbar motoraksel (4), en bevegelsesaksel (6), en gjenget overføring (7, 8) mellom motorakselen og bevegelsesakselen, en bæreramme (9), en styringsstøtte (10, 11) mellom bærerammen (9) og bevegel- sesakselen (6) for å forandre motorakselens roterende bevegelse til en lineær bevegelse for bevegelsesakselen, og videre en klarings-fjerningsanordning (12) for å fjerne klaring i aksial retning. Den gjengede overføringen (7, 8) mellom mo- torakselen (4) og bevegelsesakselen (6) omfatter en innvendig gjenge (7) i motor- akselen (4) og en utvendig gjenge (8) på bevegelsesakselen (6). l samsvar med oppfinnelsen omfatter aktuatoren for lineær bevegelse en anordning (12 eller 30) for å fjerne vertikale, horisontale og rotasjonsmessige klaringer.
