Description
eoo1s13¿4 got i förhållande till sidoväggen förskjutet kraftmoment på valsens axel. eoo1s13¿4 got in relation to the side wall displaced force moment on the shaft of the roller.
De bifogade ritningarna visar ett utföringsexempel på en lagerdel en- ligt uppfinningen. - Fä.1 visar genom en perspektivvy en lagerdel tillsammans med en sidovägg och en skrivvais, med dessa delar isärförda. - Fig. 2 är en sidovy av en monterad lagerdel. I Lagerdelen 1 har en urtagning 2 för mottagande av skrivvalsens Ä axel 3. 1 skrivvalsaxelns 3 urborrning 5 kan valsens vridknappar iskruvas.The accompanying drawings show an exemplary embodiment of a bearing part according to the invention. Fä.1 shows through a perspective view a layer part together with a side wall and a writing path, with these parts separated. Fig. 2 is a side view of a mounted bearing part. In the bearing part 1 it has a recess 2 for receiving the shaft 3 of the writing roller 3. In the bore 5 of the writing roller shaft 3, the rotary knobs of the roller can be screwed in.
På lagerdelen 1 har anordnats två flänsar 6 och 7 i form av halvcirklar V med en radie som är större än radien hos lagerdelens 1 kärna 8. Flänsarnas 6 och 7 innersidor är avfasade så att det erhålles ett kilspår 9 med en inre ; bredd som svarar mot sidoväggarnas 10 tjocklek.On the bearing part 1 two flanges 6 and 7 in the form of semicircles V have been arranged with a radius which is greater than the radius of the core 8 of the bearing part 1. width corresponding to the thickness of the side walls 10.
På flänsarnas 6 och 7 andra sida har anordnats klämskänklar 11 och 12, och den ena, 12, har utbildats elastisk. Klämskänkeln 11 har en avfasad skuldra 13.Clamping legs 11 and 12 have been arranged on the other side of the flanges 6 and 7, and one, 12, has been formed elastically. The clamping leg 11 has a chamfered shoulder 13.
Mellan klämskänklarna 11 och 12 kan en tillkommande tryckfjäder ik anordnas.Between the clamping legs 11 and 12 an additional compression spring ik can be arranged.
För mottagande av lagerdelen 1 tjänar en motsvarande urtagning 15 i sido- väggen 10. Urtagningen 15 består av en nedre smalare del 16 och en övre bredare del 17, som är öppen uppåt. Vid den övre delens 17 kant 18 uppvisar sidoväggens 10 begränsande material en klack 19 med en sned kant 20.To receive the bearing part 1, a corresponding recess 15 serves in the side wall 10. The recess 15 consists of a lower narrower part 16 and an upper wider part 17, which is open upwards. At the edge 18 of the upper part 17, the limiting material of the side wall 10 has a lug 19 with an oblique edge 20.
Monteringen av en skrivvals sker på följande sätt. Före iskruvningen av valsens vridknappar påsättes lagerdelen 1 med sin urtagning 2 på skrivvalsens Ä axel 3. Lagerdelen 1 införes därefter under sammantrycknlng av de båda kläm- skänklarna 11 och 12 uppifrån i sidoväggens 10 urtagning 15. Därvid kommer kilspåret 9 att gå ned i den nedre delen 16 av urtagningen 15 i sidoväggen 10, varigenom skrivvalsen genom kanterna 16a, 16b och 16c erhåller ett säkrat läge i sidoväggens 10 plan. Skuldran 13 på klämskänketn 11 kommer därvid att lägga sig mot klackens 19 sneda kant 20 och säkrar därigenom lagerdelen mot rörelse uppåt. Genom den av fjädern lä utövade kraften kommer den elastiska klämskänkeln 12 att tryckas mot den övre kanten 17a på den övre delen 17 av urtagningen 15.The assembly of a writing roller takes place in the following manner. Before screwing in the rotary knobs of the roller, the bearing part 1 is fitted with its recess 2 on the axis 3 of the writing roller. the part 16 of the recess 15 in the side wall 10, whereby the writing roller through the edges 16a, 16b and 16c obtains a secured position in the plane of the side wall 10. The shoulder 13 on the clamping leg 11 will then lie against the oblique edge 20 of the heel 19 and thereby secure the bearing part against upward movement. Due to the force exerted by the spring 1a, the elastic clamping leg 12 will be pressed against the upper edge 17a of the upper part 17 of the recess 15.
Skuldran 13 kan således icke ofrivilligt glida fram under klacken 19. För ut- tagning av skrivvalsen kommer efter hoptryckning av klämskänklarna lagerdelen att svängas- något i den riktning som anges av pilen A i fig. 2 och kan därefter be- kvämt uttagas uppåt ur sídoväggen 10. Lagerdelen anordnas vid skrivvalsens Å båda sidor. Det är därvid likgiltigt om skrivvalsen kommer till användning i en skrivmaskin med rörlig eller stationär pappersbärare. Om pappersbäraren är rörlig, utgöres sidoväggen 10 samtidigt av vagnens sidovägg. Om pappersbäraren är stationär, kan sidoväggen 10 samtidigt utgöra en del av maskinens stativ. Vid stora skrivmaskiner, där skrivvalsen uppvisar en avseväfidu massa, är det att föredraga att mellan klämskänklarna 11 och 12 anordna den nämnda tryckfjädern ih.The shoulder 13 can thus not involuntarily slide forward under the lug 19. After removing the writing roller, after pressing the clamping legs, the bearing part will be pivoted slightly in the direction indicated by the arrow A in Fig. 2 and can then be conveniently removed upwards from the side wall 10. The bearing part is arranged at both sides of the writing roller Å. It does not matter whether the writing roller is used in a typewriter with a movable or stationary paper carrier. If the paper carrier is movable, the side wall 10 is simultaneously formed by the side wall of the carriage. If the paper carrier is stationary, the side wall 10 may simultaneously form part of the stand of the machine. In the case of large typewriters, where the writing roller has a considerable mass, it is preferable to arrange the said compression spring ih between the clamping legs 11 and 12.
Vid mindre maskiner och särskilt genom motsvarande materialval som lagerdelen 1 är framställd av kan man utesluta denna fjäder.In the case of smaller machines and in particular by the corresponding choice of material from which the bearing part 1 is made, this spring can be excluded.
Såsom framgår av ritningarna förenklas genom den enligt uppfinningen ut- 8001513-4 bildade lagerdelen monteringen av skrlvvalsen avsevärt och blir även billigare utan att densammas funktion påverkas skadligt. Av särskild fördel är dessutom, såsom redan angivits, att det av klacken 19 på skuldran 13 utövade trycket på skrivvalsaxeln 3 ligger precis i sidoväggang 10 plan.As can be seen from the drawings, the bearing part formed according to the invention simplifies the mounting of the screw roller considerably and also becomes cheaper without its function being adversely affected. It is also of particular advantage, as already stated, that the pressure exerted by the lug 19 on the shoulder 13 on the writing roller shaft 3 lies flat in the side wall 10.
