Description

\)'1 |....ø Û 15 %¶031Û9-8 2 som genom en lëngdslits 5 står i förbindelse med gummicylinderns yta 4. Borrningen 2 har ett lagersäte 5, i vilket en ände av spännaxeln 6 är roterbart lagrad. Den andra änden av spännaxeln 6 är lagrad i en i borrningen 2 centrerad fläns 7 och vridfast förbunden med en skruvväxel 8. I den som hålaxel utförda ochumed en axiellt utsträckt införingsöppning 9 försedd att spänna axeln 6 är två klämaxlar ll anordnade på avstånd från varandra. Dessa klämaxlar ll står i beröring med väggen 10 av hàlrummet i spänn- axeln 6 och är i sina ändar lagrade för fri rörelse mot varandra i vardera ett lagerblock 12. Varje lagerblock 12 är glidbart styrt på ett i tvärriktning mot spännaxeln 6 monterat stift lö och tryc- kes i riktning mot införingsöppningen 9 genom påverkan av en trygk_ fjäder 14. Diametern av klämaxlarna ll är så avpassad, att en ände av gummiduken l5 kan fritt införas mellan de båda klämaxlarna ll, medan dukens andra ände endast kan införas under tryck. Detta med- för en förskjutning av lagerblocken 12, varigenom klämaxlarna ll glider från varandra under fortsatt beröring av väggen 10 av hål- rummet i spännaxeln 6, till dess nämnda ände av gummiduken 5 kan införas. Under påverkan av tryckfjädrarna 14 fasthålles Fndarna av gummiduken l5 mellan de båda klämaxlarna ll. Vid inspänningS_ förloppet, som kan ske under rotation av spännaxeln i endera rikt- ningen, får klämaxlarna ll en tendens att förflytta sig i rikt- ning mot införingsöppningen 9 tillsammans med ändarna av gummi- duken 15, varvid de orubbligt fasthåller gummiduken l5 under stän- dig beröring av hålrummets vägg 10. \) '1 | .... ø Û 15% ¶031Û9-8 2 which through a longitudinal slot 5 communicates with the surface 4 of the rubber cylinder. The other end of the clamping shaft 6 is mounted in a flange 7 centered in the bore 2 and rotatably connected to a screw gear 8. These clamping shafts 11 are in contact with the wall 10 of the cavity in the clamping shaft 6 and are mounted at their ends for free movement towards each other in each bearing block 12. Each bearing block 12 is slidably guided on a pin loosely mounted on the clamping shaft 6 and is pressed in the direction of the insertion opening 9 by the action of a safety spring 14. The diameter of the clamping shafts 11 is so adapted that one end of the rubber cloth l5 can be freely inserted between the two clamping shafts 11, while the other end of the cloth can only be inserted under pressure. This causes a displacement of the bearing blocks 12, whereby the clamping shafts 11 slide apart while continuing to touch the wall 10 of the cavity in the clamping shaft 6, until said end of the rubber cloth 5 can be inserted. Under the influence of the compression springs 14, the fingers of the rubber cloth 15 are held between the two clamping shafts 11. During the clamping process, which can take place during rotation of the clamping shaft in either direction, the clamping shafts 11 have a tendency to move in the direction of the insertion opening 9 together with the ends of the rubber cloth 15, they steadfastly holding the rubber cloth 15 under the posts. you touch the cavity wall 10.

För utbyte av gummiduken 15 roteras spännaxeln 6 åter till utgångsläget. Med hjälp av ett konventionellt verktyg, som ingri- per genom längdslitsen 5 och införingsöppningen 9, can lager- blocken 12 återföras mot verkan av tryckfjädrarna 14 och ändarna av gummiduken 15 därigenom frigöras.To replace the rubber cloth 15, the clamping shaft 6 is rotated back to the initial position. By means of a conventional tool, which engages through the longitudinal slot 5 and the insertion opening 9, the bearing blocks 12 can be returned against the action of the compression springs 14 and the ends of the rubber cloth 15 are thereby released.
