Opfindelsen angår et gliderkurvedrivværk af den i krav l*s indledning angivne art.The invention relates to a sliding basket drive of the type specified in the preamble of claim 1 *.

Ved et kendt drivværk af denne art (jrøtte, Maschinenbau, del A,By a known drive of this kind (root, Maschinenbau, part A,

Berlin 1954, side 311) er rullerne anbragt i en afstand fra hinanden, der er parallel med aksen for kurvebæreren og for gliderens bevægelsesbane.Berlin 1954, page 311), the rollers are arranged at a distance from each other which is parallel to the axis of the basket carrier and of the path of movement of the slider.

Derved må bredden af vulsten på de steder, hvor kurvestigningeh er stor, være lille, og på de steder, hvor kurvestigningen er lille, være stof, for at kurven ved. enhver forekommende stigning kan løbe frit uden spillerum mellem rullerne.Thereby, the width of the bead in the places where the curve rise is large must be small, and in the places where the curve rise is small, must be fabric for the curve to know. any incline may run freely with no clearance between the rollers.

Fremstillingen af en sådan vulstkurve, hvis bredde er foranderlig i en grad, der afhænger af den stedlige stigning af kurven, er meget omstændelig og kostbar. Når kurvebæreren er lang, og vulstkurven med foranderlig bredde har mange vindinger, er en økonomisk fremstilling overhovedet ikke mulig. Af den grund har anvendelsen af glidekurvedrivværker af 141138 2 den nævnte art hidtil været begrænset til tilfælde, i hvilke man kan nøjes med en enkel kurvebærervinding, som det f. eks. er tilfældet ved det kendte driwærk. Derved bliver gliderbevægelsen tilsvarende kort. Glider-kurvedriwærker med talrige vulstkurve-vindinger på en lang kurvebærer har hidtil kun kunnet udføres med en vulstkurve med konstant bredde, d. v.s. kun til en jævn drivbevægelse. Derfor har man hidtil f. eks. til drift af garageporte måttet undvære en ved begyndelsen accelereret og ved slutningen retarderet bevægelse, selv om en sådan bevægelse øjensynlig både ville være ønskelig og fordelagtig.The manufacture of such a bead curve, the width of which is variable to a degree depending on the local rise of the curve, is very cumbersome and expensive. When the basket carrier is long and the bead basket with variable width has many turns, an economical manufacture is not possible at all. For this reason, the use of sliding curve drives of the type mentioned has hitherto been limited to cases in which a simple curve carrier winding can be satisfied, as is the case, for example, with the known drive. Thereby, the sliding movement becomes correspondingly short. Glider curve drives with numerous bead curve windings on a long basket carrier have so far only been able to be performed with a bead curve of constant width, i.e. only for a smooth driving motion. Therefore, for example, for the operation of garage doors, for example, a movement accelerated at the beginning and retarded at the beginning has had to be dispensed with, even though such a movement would obviously be both desirable and advantageous.

Opfindelsen tager sigte på at angive et drivværk af den nævnte art, ved hvilket denne ulempe er undgået.The object of the invention is to provide a drive of the type mentioned in which this disadvantage is avoided.

Dette opnås ifølge opfindelsen ved, at drivværket er udformet som angivet i krav l’s kendetegnende del.This is achieved according to the invention in that the transmission is designed as stated in the characterizing part of claim 1.

Ved denne udformning opnår man, at stillingen af rulleparret altid tilpasser sig til stigningen af kurven, så at det ikke mere er nødvendigt at udforme kurven bred ved lille stigning og smal ved stor stigning; vulstkurven kan have konstant bredde. Derved undgår man også den hidtidige ulempe, at vulstkurven for at være tilstrækkelig stærk på sit smalleste sted måtte gøres alt for bred på det bredeste sted.With this design it is obtained that the position of the pair of rollers always adapts to the rise of the basket, so that it is no longer necessary to design the basket wide at small rise and narrow at high rise; the bead curve can have a constant width. This also avoids the previous disadvantage that the bead curve, in order to be sufficiently strong in its narrowest place, had to be made too wide in the widest place.

Vulstkurven med konstant bredde er let at fremstille, den kan dannes af en på kurvebæreren viklet og til denne fastgjort, f. eks. påsvej-set og/eller i en not liggende tråd, hvad der er kendt fra glidekurve-drivværker med jævn drivbevægelse fra beskrivelsen til USA-patent nr.The constant width bead basket is easy to manufacture, it can be formed by a wire wound on the basket carrier and attached to it, for example welded on and / or in a groove lying, which is known from sliding basket drives with smooth drive movement from the description of U.S. Pat.

For at lette tilpasningen af stillingen af rulleparret til stigningen af vulstkurven er rullerne hensigtsmæssigt symmetriske i forhold til svingningsaksen for rulleparret. Rulleakserne kan danne en vinkel, hvis vinkelhalveringslinie falder sammen med svingningsaksen, hvorved rulleparret i hver stilling udøver en mod kurvebæreren rettet kraft og derved føres pålideligt på bæreren. Kurvebæreren kan på den side, der ligger overfor rulleparret, være understøttet af et føringsorgan, f. eks. et giidestykke eller en rulle. Dette er fordelagtigt, idet man ved drivværket ifølge opfindelsen kan anvende en lang kurvebærer (en vulstkurve med talrige vindinger), der kunne bøje sig og undvige fra rulleparret, når der ikke blev optaget en tiltrykningskraft ved skråstillingen af rullerne og en modsat rettet kraft ved hjælp af føringsorganet. Føringsorganet skal enten have en længde, der er tilpasset til den største stigning af vulstkurven for at understøtte kurven på ethvert sted af kurvebæreren, eller føringsorganet skal være en med en omkredsrille forsynet rulle, 141138 3 der løber på vulstkurven og er forskydelig parallel med kurvebæreaksen et stykke, derer tilpasset til den største stigning af vulstkurven.In order to facilitate the adjustment of the position of the roller pair to the rise of the bead curve, the rollers are suitably symmetrical with respect to the pivot axis of the roller pair. The roller axes can form an angle whose angle bisector coincides with the axis of oscillation, whereby the pair of rollers in each position exerts a force directed towards the basket carrier and thereby is reliably applied to the carrier. The basket carrier can on the side opposite the pair of rollers be supported by a guide member, for example a guide piece or a roller. This is advantageous in that in the case of the transmission according to the invention a long basket carrier (a bead basket with numerous turns) can be used, which could bend and dodge from the pair of rollers when no compressive force was absorbed by the inclination of the rollers and an opposite force by means of of the guide means. The guide means must either have a length adapted to the largest pitch of the bead basket to support the basket at any point of the basket carrier, or the guide means must be a roller provided with a circumferential groove, 141138 3 running on the bead basket and slidably parallel to the basket carrying axis. piece, derer adapted to the largest rise of the bead curve.

En rulle med omkredsrille er ikke anvendelig ved kendte vulstkur-ver, der har et foranderligt tværsnit.A circumferential groove roller is not applicable to known bead curves having a variable cross-section.

Opfindelsen forklares nærmere under henvisning til tegningen, på hvilken fig. 1 viser en første udførelsesform for gliderkurvedriv-værket ifølge opfindelsen set fra siden og delvist i snit, fig. 2 et tværsnit efter en linie ΙΙ-Π i fig. 1, i større målestok, fig. 3 en enkelthed ved en anden udføreisesform for driv-værket, set på samme måde som udførelsesformen i fig. 1, men i samme målestok som i fig. 2, og fig. 4 et snit efter en linie TV-IV i fig. 3.The invention is explained in more detail with reference to the drawing, in which fig. 1 shows a first embodiment of the slider basket drive according to the invention seen from the side and partly in section, fig. 2 is a cross-section along a line ΙΙ-Π in FIG. 1, on a larger scale, fig. 3 shows a simplicity of another embodiment of the drive, seen in the same way as the embodiment in fig. 1, but on the same scale as in FIG. 2, and FIG. 4 is a section along a line TV-IV in fig. 3.

Gliderkurvedriwærket i fig. 1 og 2 består af en cylindrisk kurvebærer 1, der danner et drivelement og har en vulstkurve 2, samt en et drevet element dannende glider 3, der er lejret forskydeligt i en føring 4 parallelt med aksen for kurvebæreren 1. I fig. 1 er kun vist to ender og en midterste del af kurvebæreren 1, vulstkurven 2 og føringen 4.The sliding curve drive in fig. 1 and 2 consist of a cylindrical basket carrier 1, which forms a drive element and has a bead curve 2, as well as a slider 3 forming a driven element, which is displaceably mounted in a guide 4 parallel to the axis of the basket carrier 1. In fig. 1 shows only two ends and a middle part of the basket carrier 1, the bead basket 2 and the guide 4.

Vulstkurven 2 er dannet af en tråd, def er viklet på kurvebæreren 1 med en stigning, der forløber svarende til den Ønskede uensartethed i den drevne bevægelse, og er fikseret, f, eks. svejset på kurvebæreren 1. Denne er ved begge ender lejret i lejer 5 og ved den ene ende ved hjælp af en akselkobling 6 forbundet med en drivmotor 7, hvis omdrejnings-retning er omstyrbar.The bead basket 2 is formed by a wire, def is wound on the basket carrier 1 with a pitch corresponding to the desired non-uniformity in the driven movement, and is fixed, eg welded to the basket carrier 1. This is mounted at both ends in bearings 5 and at one end by means of a shaft coupling 6 connected to a drive motor 7, the direction of rotation of which is reversible.

Glideren 3 består af et stel med to ovenfor hinanden liggende vinkeljern 8 og 9. På ydersiderne af vinkeljernene er der drejeligt lejret løberuller 10, som ligger an mod indersiden af hver sin flange på et af to vinkeljern 11, som danner føringen 4.The slider 3 consists of a frame with two superimposed angle irons 8 and 9. On the outer sides of the angle irons there are rotatably mounted running rollers 10, which abut against the inside of their respective flanges on one of two angle irons 11, which form the guide 4.

To ruller 12, hvis akser danner en vinkel med hinanden, er lejret frit drejeligt på vinkeljernet 8 om en aksel 15, der forløber i retning af en vinkelhalveringslinie for den vinkel, som rullernes akser danner med hinanden. Akslen 13 er anbragt radialt i forhold til kurvebæreren 1, og rullerne 12 ligger overfor hinanden an mod vulstkurven. Da rullerne 12 er frit svingelige om akslen 13, kan de tilpasse deres stilling i forhold til vulstkurven 2 til den øjeblikkelige stigningsvinkel for vulstkurven 2, så at berøringsstederne på rullerne 12 på vulstkurven 2 og de geometriske ak- i.Two rollers 12, the axes of which form an angle with each other, are mounted freely rotatably on the angle iron 8 about an axis 15 extending in the direction of an angle bisector of the angle which the axes of the rollers form with each other. The shaft 13 is arranged radially relative to the basket carrier 1, and the rollers 12 abut each other against the bead basket. Since the rollers 12 are freely pivotable about the shaft 13, they can adjust their position relative to the bead basket 2 to the instantaneous angle of inclination of the bead basket 2, so that the contact points on the rollers 12 on the bead basket 2 and the geometric axes.

4 1A1138 ser for rullerne 12 altid praktisk talt ligger i et plan, der står vinkelret på aksen for vulstkurven 2.4 1A1138 looks for the rollers 12 always practically lying in a plane perpendicular to the axis of the bead curve 2.

Overfor rulleparret 12 er der til glideren 3 fastgjort to førings-slidser 14, som består af polyamidformstof, såkaldt nylon, og som ligger an mod vulstkurven 2 og under drift af drivværket glider med ringe friktion på kurven 2. Længden af listerne 12 skal mindst svare til den største stigning af vulstkurven 2. En tap 15, der er fastgjort til glideren 3, tjener til forbindelse med den del, som skal drives ved hjælp af drivværket.Opposite the roller pair 12, two guide slots 14 are attached to the slider 3, which consist of polyamide plastic, so-called nylon, and which abut against the bead basket 2 and during operation of the drive slide with little friction on the basket 2. The length of the strips 12 must at least correspond to the largest pitch of the bead basket 2. A pin 15 attached to the slider 3 serves to connect to the part to be driven by the drive.

Den afvigende del af den anden udførelsesform for drivværket, der er vist i fig. 3 og 4, har i forhold til den i fig. 1 og 2 viste udførelsesform i stedet for lister 14 en rulle 16 med en omkredsnot 17, der er tilpasset til en del af tværsnittet af vulstkurven 2. Rullen 16 er drejelig i en gaffel 18. Denne er fast forbundet med en tap 19, der er drejelig i en anden glider 20. Den geometriske akse for tappen 19 skærer de geometriske akser for rullen 16 og for kurvebæreren 1 vinkelret og ligger sammen med aksen 13 i et lodret plan. Derved kan rullen 16 tilpasse sin stilling i forhold til kurvebæreren til den øjeblikkelige stigningsvinkel på vulstkurven. Den anden glider 20 er forskydelig i en føring 21 parallel med vinkeljernet 9 og dermed også parallel med kurvebæreren 1 over en strækning, der er noget større end den største stigning af vulstkurven 2. Dette er nødvendigt, fordi afstanden af rullen 16 fra rulleparret i længderetningen for kurvebæreren afhænger af stigningen af den del af vulstkurven 2, mod hvilken rulleparret 12 og rullen 16 ligger an.The deviating part of the second embodiment of the drive shown in fig. 3 and 4, relative to that of FIG. 1 and 2, instead of strips 14, a roller 16 with a circumferential groove 17 adapted to a part of the cross section of the bead basket 2. The roller 16 is rotatable in a fork 18. This is fixedly connected to a pin 19 which is rotatable in another slider 20. The geometric axis of the pin 19 intersects the geometric axes of the roller 16 and of the basket carrier 1 perpendicularly and lies together with the axis 13 in a vertical plane. Thereby, the roller 16 can adjust its position relative to the basket carrier to the instantaneous angle of inclination of the bead basket. The second slider 20 is displaceable in a guide 21 parallel to the angle iron 9 and thus also parallel to the basket carrier 1 over a distance which is somewhat larger than the largest pitch of the bead curve 2. This is necessary because the distance of the roller 16 from the pair of rollers in the longitudinal direction for the basket carrier depends on the rise of the part of the bead basket 2 against which the pair of rollers 12 and the roller 16 abut.

Ved drivværker med forholdsvis lille drivende kraft er den i fig.In the case of drives with relatively little driving force, the device shown in fig.

1 og 2 viste udførelsesform for drivværket tilstrækkelig, medens der til drivværker med større afgiven drivende kraft må foretrækkes den i fig. 3 og 4 viste udførelsesform.1 and 2 of the drive train is sufficient, while for drives with a greater driving force, the one shown in fig. 3 and 4.

Kurvebæreren 1 kan være forsynet med en not, i hvilken en del af et tværsnit af den tråd, der danner noten, sidder, idet denne yderligere kan være fastsvejset.The basket carrier 1 may be provided with a groove in which a part of a cross-section of the wire forming the groove sits, this being further welded.

Drivværket ifølge opfindelsen har navnlig følgende fordele:The drive according to the invention has in particular the following advantages:

Vulstkurven med konstant bredde kan fremstilles på enkel måde ved opvikling af en tråd på kurvebæreren. Dette er af særlig betydning, når vulstkurven forløber i talrige vindinger om en forholdsvis lang kurvebærer, og når stigningsvinklen for vulstkurven langs kurvebæreren ændrer sig væsentligt, f. eks. for at accelerere en stor masse fra stilstand med forholdsvis lille ydelse lidt efter lidt, derefter at bevæge massen med konstant hastighed og atter at retardere massen indtil stilstand. Et godtThe bead basket with constant width can be manufactured in a simple manner by winding a wire on the basket carrier. This is of particular importance when the bead curve runs in numerous turns about a relatively long basket carrier, and when the angle of inclination of the bead basket along the basket carrier changes significantly, eg to accelerate a large mass from standstill with relatively little performance little by little, then to move the mass at a constant speed and to retard the mass again to a standstill. A good

Claims

5 141138 example of a drive unit of this type is a drive unit used for opening and closing a heavy gate. For such an application, the pitch angle of the bead kit in FIG. 1 smaller at the ends of the basket carrier than on the middle part of the basket carrier. With a bead curve with a constant width, a greater variation of the pitch angle is possible than with the known bead curve, whose width is smaller in places with a larger pitch angle and larger in places with a smaller pitch angle. Furthermore, it has been found that the pivotal pair of rollers, which automatically adjusts its position to the angle of inclination, is superior in friction loss and propensity to block in relation to the known rigidly arranged roller pairs, in which the mutual distance between the rollers is always parallel to the direction in which the driving force is delivered.
