Description

40 e1oo2oa-s g 2 fig. 3 visar detaljen enligt fig. 2 i tvärsnïtï”oEh'fig. 4 och 5 visar vyer svarande mot de som visas i fig. 2 och 3 men av en annan utföríngsform av berörda detalj. Fig. 3 shows the detail according to Fig. 2 in cross-section. Figures 4 and 5 show views similar to those shown in Figures 2 and 3 but of a different embodiment of the details concerned.

Anordningen är uppbyggd av en yttre, stationär cylinder- formad hylsa 1 samt en inuti denna vridbart anordnad hylsa 2.The device is built up of an outer, stationary cylindrical sleeve 1 and a sleeve 2 rotatably arranged inside it.

Hylsan 2 är i det visade exemplet lagrad i hylsan 1 i två kul- eller rullager 3. Vid den ena, slutna änden av hylsan 1 är ett monteringsöra 4 anordnat. Den inre hylsans vridning åstadkommas med hjälp av en índuktionsmotor, vars rotor är fast förbunden med hylsan 2 och schematiskt antyds med 5 och vars stator med lindningar antyds med 6, vilken stator är fastsatt vid hylsan 1.In the example shown, the sleeve 2 is stored in the sleeve 1 in two ball or roller bearings 3. At one, closed end of the sleeve 1, a mounting ear 4 is arranged. The rotation of the inner sleeve is effected by means of an induction motor, the rotor of which is fixedly connected to the sleeve 2 and is schematically indicated by 5 and whose stator with windings is indicated by 6, which stator is attached to the sleeve 1.

Den inre hylsan 2 är försedd med gängformat förlöpande spår 7 på insidan. En stång 8, med ett drivorgan, som senare skall beskrivas, sträcker sig ovridbart men rörligt fram och åter genom den inre hylsans 2 öppna ände och genom en muff 9, fastsatt på den yttre hylsan 1. Stångens utanför hylsorna be- fintliga ände är utrustad med likaså ett monteringsöra 10.The inner sleeve 2 is provided with thread-shaped extending grooves 7 on the inside. A rod 8, with a drive means, to be described later, extends non-rotatably but movably back and forth through the open end of the inner sleeve 2 and through a sleeve 9, attached to the outer sleeve 1. The end of the rod located outside the sleeves is equipped with likewise a mounting ear 10.

Det på stången 8 anordnade drivorganet består av en med- n bríngarskiva 11 samt en medbringare 12, fixerad vid delen 11 medelst två diametralt omkring stången 8 anordnade axlar 13. Vardera axeln uppbär ett fritt roterbart hjul 14. Respektive hjul är försett med perifera, parallella flänsar eller ansatser 15 med sidor,_som i det visade exemplet ligger i plan vinkelräta mot rotationsaxeln. Vid ändarna av resp. hjul är stödlager 16 anordnade.The drive member arranged on the rod 8 consists of a carrier disc 11 and a driver 12, fixed to the part 11 by means of two shafts 13 arranged diametrically around the rod 8. Each shaft carries a freely rotatable wheel 14. Each wheel is provided with peripheral, parallel flanges or shoulders 15 with sides, which in the example shown lie in planes perpendicular to the axis of rotation. At the ends of resp. wheels, support bearings 16 are provided.

Over hjulen 14 är ett ändlöst band 17 anordnat förlöpande så som' närmare framgår av fig. 5. Detta band är på insidan försett med flänsarna eller ansatserna motsvarande spår eller urtagningar, varigenom bandet styrs på hjulen. Bandet 17 är vidare på utsidan försett med en spiralprofil som motsvarar den inre hylsans Z gängformat förlöpande spår 7. Som klart torde inses pressas bandet 17 till ingrepp med hylsans Z spiralspår 7 av hjulen 14 i två diametralt motsatta områden. Vid det inre rörets 2 vrid- ning i förhållande till stången 8, liksom den yttre hylsan 1, kommer bandet att, pressat mellan hylsan 2 och hjulen 14, att rulla mot hylsans 2 insida i ingrepp med dennas gängspår.Above the wheels 14 an endless belt 17 is arranged extending as can be seen in more detail in Fig. 5. This belt is provided on the inside with the flanges or shoulders corresponding grooves or recesses, whereby the belt is guided on the wheels. The belt 17 is further provided on the outside with a spiral profile corresponding to the threaded groove 7 of the inner sleeve Z. As will be clear, the belt 17 is pressed into engagement with the spiral groove 7 of the sleeve Z by the wheels 14 in two diametrically opposite areas. When the inner tube 2 is rotated relative to the rod 8, as well as the outer sleeve 1, the belt will, pressed between the sleeve 2 and the wheels 14, roll towards the inside of the sleeve 2 in engagement with its threaded groove.

Bandet 17 kommer därvid att "klättra" utefter hylsan 2 och genom urtagningarnas samverkan med ansatserna hos hjulen belasta dessa med en axialkraft, förskjutande stången 8 i en bestämd riktning beroende på hylsans 2 rotationsriktning. Genom hjulens 3 a1oo2os-s 14 diametrala placering är stången 8 hela tiden'štVrd'ï hylsan 2. Den stången 8 drivande spiralprofilen är i detta fall anordnad på det ändlösa bandet 17, som i detta fall i två områden ingriper med hylsans gängor, vilket innebär att spiralprofilens båda ingreppsomrâden hela tiden rör sig med samma hastighet. Detta innebär i sin tur att även om bandet vid osymmetrisk belastning eller feldimensionering skulle "lätta" från hylsans 2 insida vid ett av hjulen 14 eller ett snedriktande moment skulle upp- träda hos hjul eller medbringar 11, 12, kommer någon klämning eller kärvning ej att uppträda av anordníngen, emedan bandet och därmed spiralprofilen i detta område ändock fortfarande har samma hastighet som i det andra området, vilken hastighet till- närmelsevis svarar mot hastigheten hos hylsans Z insida.The belt 17 will then "climb" along the sleeve 2 and through the interaction of the recesses with the shoulders of the wheels load them with an axial force, displacing the rod 8 in a certain direction depending on the direction of rotation of the sleeve 2. Due to the diametrical location of the wheels 3 a1oo2os-s 14, the rod 8 is always'štVrd'ï the sleeve 2. The spiral profile driving the rod 8 is in this case arranged on the endless belt 17, which in this case in two areas engages the threads of the sleeve, which means that the two engaging areas of the spiral profile constantly move at the same speed. This in turn means that even if the belt would "lighten" from the inside of the sleeve 2 at one of the wheels 14 or an oblique moment in the case of asymmetrical loading or incorrect dimensioning at wheels or carriers 11, 12, no squeezing or jamming will occur. occur of the device, because the belt and thus the spiral profile in this area still has the same speed as in the other area, which speed corresponds approximately to the speed of the inside of the sleeve Z.

I fig. 4 och 5 visas en anordning, vid vilken medbringar- skivan 11 och medbringaren 12, i detta fall i form av en cirkulär skiva, fixerat vid varandra uppbär tre stycken axlar 13 för fritt roterbart lagrade hjul 19. Resp. hjul är på sin mantelyta för- sett med en spiralprofil svarande mot hylsans 2 inre gängform 7. Hjulen 19 är så anordnade, att de jämnt fördelade omkring stången 8 samtliga står i ingrepp med hylsans Z gängor. Hjulen är vidare försedda med var sitt kuggdrev 20. Koaxiellt med stången 8 är ett kugghjul 18 lagrat fritt roterbart, lämpligen omkring en axeltapp (ej visad) anordnad hos medbringarskivan 11. Vid hylsans_2 vridning rullar hjulen på insidan av hylsan och överför själva direkt den axiella kraften till stången 8. Hjulens och därmed dess spiralprofilers hastighet är alltid lika p.g.a. kugg- hjulets 18 ingrepp med hjulens kuggdrëv 20. Härigenom undviks på samma sätt som tidigare beskrivits kärvning eller klämning av anordningen vid oavsedda och avvikande rörelseförlopp.Figs. 4 and 5 show a device in which the carrier disc 11 and the carrier 12, in this case in the form of a circular disc, fixed to each other, support three axles 13 for freely rotatably mounted wheels 19. Resp. wheels are provided on their mantle surface with a spiral profile corresponding to the inner thread shape 7 of the sleeve 2. The wheels 19 are arranged such that they are evenly distributed around the rod 8 and all engage with the threads Z of the sleeve. The wheels are further provided with their respective gears 20. Coaxially with the rod 8, a gear 18 is mounted freely rotatable, suitably about a shaft pin (not shown) arranged on the drive disc 11. When the sleeve 2 is rotated, the wheels roll on the inside of the sleeve and directly transfer the axial the force to the rod 8. The speed of the wheels and thus its spiral profiles is always equal due to the engagement of the gear wheel 18 with the gear drive 20 of the wheels. In this way, in the same way as previously described, jamming or squeezing of the device is avoided in the event of unintentional and deviating movements.

Inom ramen för uppfinningen är det möjligt att variera antalet hjul vid båda de här beskrivna utföringsexemplen. Vid användande av flera hjul erhalles totalt sett ett större ingrepps- område mellan band/hjul och hylsa, varigenom större axialkrafter kan upptas av anordningen.Within the scope of the invention, it is possible to vary the number of wheels in both of the embodiments described here. When using several wheels, a larger engagement area is obtained overall between the belt / wheel and the sleeve, whereby greater axial forces can be absorbed by the device.

Genom att som visats anordna den drivande elmotorns rotor och stator som integrerande enheter i de båda cylindrarna eller hylsorna, är det möjligt att på ett enkelt sätt ersätta pneuma- tiska och hydrauliska kolv-cylinderenheter med den på motsvarande sätt verkande eldrivna anordningen enligt uppfinningen.By arranging, as shown, the rotor and stator of the driving electric motor as integrating units in the two cylinders or sleeves, it is possible to easily replace pneumatic and hydraulic piston-cylinder units with the correspondingly acting electric device according to the invention.
