(54) Kontaktindretning til en roteren= de drivmekanisme.(54) Rotary contact device = the drive mechanism.
Opfindelsen angår en kontaktindretning til en roterende drivmekansime med en kontakt, som efter et forud bestemt antal omdrejninger af drivmekanismen afgiver en impuls, hvorved der er indrettet i det mindste to på samme aksel med forskellig omdrejningshastighed drevne kontakthjul, som på deres omkreds har i det mindste én udsparing, og som hver er fast forbundet med et ved siden af og på m samme aksel anordnet tandhjul.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a contact device for a rotary drive mechanism having a contact which, after a predetermined number of revolutions of the drive mechanism, provides an impulse, thereby providing at least two contact wheels driven on the same shaft at different rotational speeds which have at least their circumference. one recess, each of which is firmly connected to a sprocket arranged adjacent to and on the same shaft.

144199 2 1 En sådan kontaktindretning kendes f.eks. fra tysk fremlæggelsesskrift nr. 1.640.912. Det i dette skrift beskrevne elektriske kontaktur har et mellemhjulsdrev bestående af en melleraaksel og to derpå fastgjorte tand-5 hjul. Kontaktakselen, hvorpå kontakthjulene med tilhørende tandhjul er lejret, drives på normal måde ved hjælp af flere, ikke viste tandhjul.Such a contact device is known e.g. from German Publication No. 1,640,912. The electrical contact watch described in this specification has a mid-wheel drive consisting of a miter shaft and two sprockets attached thereto. The contact shaft on which the contact wheels and associated gears are mounted is driven normally by means of several gears not shown.
Formålet med opfindelsen er at forenkle en kontaktind-10 retning af denne art uden anvendelse af et mellemhjulsdrev.The object of the invention is to simplify a contact arrangement of this kind without the use of a mid-wheel drive.
Dette formål opfyldes ifølge opfindelsen ved, at tandhjulene kun står i indgreb med et fælles drivtandhjul og 15 har samme hoved- og fodkredsdiametre, og at deres tandantal er næsten ens, men dog forskellige.This object is achieved according to the invention in that the gears are only engaged with a common drive gear and 15 have the same main and foot circumferential diameters, and that their number of teeth is almost the same, but different.
De to tandhjul, hvis tandantal således kun adskiller sig meget lidt, kan fremstilles af indbyrdes ensformede me-20 talemner. Som følge af bortfaldet af mellemhjulene behøves kun en enkelt akseltap. Denne bærer hele kontaktindretningen og kan tjene som fastgørelse for denne, således at der alt efter anvendelsen heller ikke kræves et hus. Foruden denne konstruktive forenkling og formind-25 skelse af byggevolumenet har kontaktindretningen ifølge opfindelsen den fordel, at den ved indbygning i en maskine umiddelbart kan fastlåses på en eksisterende frontfortånding, f.eks. på et spidshjul eller en tandkrans .The two gears, the number of gears thus differing very little, can be made of mutually uniform metal blanks. Due to the failure of the center wheels, only a single shaft loss is needed. This one carries the entire contact device and can serve as an attachment for it, so that no housing is required depending on the application. In addition to this constructive simplification and reduction of the building volume, the contact device according to the invention has the advantage that it can immediately be locked onto an existing front tooth when incorporated into a machine, e.g. on a pointed wheel or a cogwheel.

Ved at forsyne kontakthjulene med kappeflader af samme diametre, som omhandlet i krav 2, vil man kunne benytte et fælles tastorgan, som ligger an mod kappefladerne.By providing the contact wheels with casing surfaces of the same diameter as defined in claim 2, a common key means which abuts against the casing surfaces can be used.
35 Ved at anvende den i krav 3 beskrevne udformning af kontakthjulet kan koblingspunkterne indstilles til vilkår- 3 146199 1 lige vinkelstillinger for drivmekanismen.By using the design of the contact wheel as described in claim 3, the coupling points can be set to equal angular positions of the drive mechanism.
Ved at udforme kontaktindretningen, som omhandlet i krav 4, kan særlig store løbeområder opnås.By designing the contact device as claimed in claim 4, particularly large running areas can be obtained.
55
Ved at anvende den i krav 5 omhandlede udformning af kontaktindretningen med to tandhjulsgrupper med hver sin' endekontakt, kan opnås en fordelagtig brug af endekoblingsorganer.By using the design of the contact device of claim 2 with two gear groups with their respective end contacts, advantageous use of end coupling means can be obtained.
1010
Endelig er det hensigtsmæssigt, som omhandlet i krav 6, at fastgøre de to stopkontakter på en fælles fremstående bærearm.Finally, as claimed in claim 6, it is appropriate to attach the two stop contacts to a common protruding support arm.
15 Opfindelsen forklares nærmere under henvisning til tegningen, hvor fig. 1 viser en dobbeltendekontaktindretning ifølge opfindelsen, set i snit efter linien I-I i fig. 2, 20 fig. 2 viser den i fig. 1 viste dobbeltendekontakt- indretning og et åbent hus, hvori den er indbygget, set fra oven, fig, 3 viser en deltegning af to indstillingsringe ifølge fig. 1 i større målestoksforhold og 25 i den stilling, som de indtager efter en omdrejning, og fig. 4 viser et aksialt snit af en anden kontaktindretning ifølge opfindelsen.BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a double end contact device according to the invention, in section along line I-I in FIG. 2, 20 FIG. 2 shows the one in FIG. 1 is a plan view of the double end contact device and an open housing in which it is incorporated; FIG. 3 is a partial drawing of two adjustment rings according to FIG. 1 in larger scale and 25 in the position which they occupy after a revolution; and FIG. 4 shows an axial section of another contact device according to the invention.
30 Den i fig. 1 og 2 viste dobbeltendeomskiftermekanisme er indbygget i et særskilt kammer 1 i et støbt drivmekanis-mehus 2, der indeholder en især til betjening af vinduerne i drivhuse egnet drivmekansime. En drivaksel-3 løber igennem kammeret 1 og er tætnet ved gennemførings-· 35 stederne, så at der hverken kan trænge fugt ind i kammeret 1 eller smørelse fra det ved siden·af liggende driv- 4 H4199 1 mekanismekammer. Et dæksel, der kan fastgøres med skru er, og som normalt aflukker kammeret 1, er vist aftaget i fig, 2. I fig. 1 er drivmekanismehuset helt udeladt.The embodiment of FIG. 1 and 2, the double end switching mechanism is built into a separate chamber 1 in a molded drive mechanism housing 2 which contains a drive mechanism suitable for operating the windows in greenhouses. A drive shaft-3 runs through the chamber 1 and is sealed at the feed-through locations, so that no moisture can enter the chamber 1 or lubrication from the adjacent drive mechanism 4 H4199 1. A cap which can be secured with screws and which normally closes the chamber 1 is shown taken in FIG. 2. In FIG. 1, the drive housing is completely omitted.
5 Den flere gange neddrejede drivaksel 3 har en endefor-tanding 4, der strækker sig i aksial retning over mere end halvdelen af kammerets bredde. Med denne fortanding står fire koblingshjul 5 til 8 i indgreb, hvilke koblingshjul er lejret på en ved hjælp af en skrue 9 vin-10 kelret på kammervæggen fastskruet aksel 10. Koblingshjulene har sidefremspring, f.eks. 8a, og er monteret med disse vendende mod hinanden. På sidefremspringene er der lejret indbyrdes identiske indstillingsringe 11 til 14, idet to indstillingsringe ligger umiddelbart an 15 mod hinanden med deres sideflader og holdes sammen af de tilsvarende koblingshjul. Indstillingsringenes ydre omkredsflader danner en fælles cylindrisk løbeflade.5 The multiple rotary drive shaft 3 has an end gear 4 extending axially over more than half the width of the chamber. With this gearing, four clutch wheels 5 to 8 are engaged, which clutch wheels are mounted on a shaft 10. screwed by means of a screw 9 angled to the chamber wall 10. The clutch wheels have side projections, e.g. 8a, and are mounted with these facing each other. On the side projections, identical adjustment rings 11 to 14 are mounted mutually, with two adjustment rings directly adjacent to one another with their side surfaces and held together by the corresponding coupling wheels. The outer circumferential surfaces of the adjustment rings form a common cylindrical running surface.
På aksen er der i midten udformet en aftrappet ringansats 15, hvorpå der før montage af koblingshjulene ved 20 påpresning er fastgjort en strimmelformet holdeplade 16,On the axis, a stepped ring assembly 15 is formed in the center, on which a strip-shaped retaining plate 16 is fastened prior to mounting of the coupling wheels.
Den springer frem i radial retning opad mod højre. Koblingshjulene 6 og 7 ligger an mod begge sider af ringansatsen, medens koblingshjulene 5 og 8 er sikret af låseringe, seegerringe, 17 og 18. Denne lejring muliggør 25 indbyrdes uafhængige drejninger både af koblingsringene og af indstillingsringene.It protrudes radially upwards to the right. The coupling wheels 6 and 7 abut on both sides of the ring assembly, while the coupling wheels 5 and 8 are secured by locking rings, sight rings, 17 and 18. This bearing allows 25 mutually independent turns both of the coupling rings and of the adjustment rings.
To omskiftere 19 og 20 er påskruet hver sin side af holdepladen 16 ved hjælp af gennemgående skruer 21. Omskif-30 terne er ens og har hver en betjeningsarm 22, på hvis forreste frie ende der er lejret en løberulle 23. Betjeningsarmene trykkes fjedrende mod indstillingsringene, så at løberullerne ved drejning af koblingshjulene og indstillingsringene ruller på løbefladerne. Betjenings-35 armene er indstillet på en sådan måde, at løberullerne ligger an med en halvdel mod hver af indstillingsringene.Two switches 19 and 20 are screwed on each side of the retaining plate 16 by means of through screws 21. The switches 30 are the same and each has an operating arm 22, on the front free end of which is mounted a running roller 23. The operating arms are resiliently pressed against the adjustment rings. , so that, when turning the coupling wheels and the adjustment rings, the roller rollers roll on the running surfaces. The actuating arms are adjusted in such a way that the roller rollers abut one half against each of the adjustment rings.
5 1441$9 1 Hver indstillingsring har på omkredsen et udsnit 11a, 12a og i nærheden af udsnittet en radialt forløbende indstillingsskrue 24, der trykker mod det pågældende koblingshjuls lejeansats, og gør det muligt at fastlåse 5 indstillingsringen i enhver ønsket vinkelstilling i forhold til koblingshjulet. I den viste udførelsesform er både koblingshjulene og indstillingsringene fremstillet af formstof. Af denne grund samvirker de forholdsvis tynde indstillingsskruer med hver sin firkantede gevind— 10 plade 25, der er indsat i en passende tværgående udsparing i indstillingsringen. Indstillingsskruerne er udformet som snekkeskruer og rager ikke ud over indstillingsringenes ydre løbeflader. De er let tilgængelige i justeringsstillingen som vist i fig. 1 foroven.Each adjustment ring has on its circumference a section 11a, 12a and in the vicinity of the section there is a radially extending adjusting screw 24 which presses against the bearing shaft of the respective clutch wheel and allows the adjustment ring to be locked in any desired angular position relative to the clutch wheel. In the embodiment shown, both the coupling wheels and the adjustment rings are made of plastic. For this reason, the relatively thin adjusting screws cooperate with each of their square threads - 10 plate 25, which is inserted into a suitable transverse recess in the adjusting ring. The adjustment screws are designed as worm screws and do not protrude beyond the outer running surfaces of the adjustment rings. They are readily available in the adjustment position as shown in FIG. 1 at the top.

De to koblingshjul og deres indstillingsringe og de tilhørende omskiftere er i den viste udførelsesform identiske. Fortandingen af koblingshjulene i koblingshjulparrene er dog indbyrdes afvigende. Hoved- og fodkredse 20 er ens, men ved hjælp af en^forskellig tanddeling har man opnået, at det ene koblingshjul har nogle få tænder -mere end det andet. I den viste udførelsesform er tandantallene 84 og 88, så at det ene koblingshjul ved hver omdrejning kommer fire tænder foran det andet.The two coupling wheels and their adjusting rings and the corresponding switches are identical in the embodiment shown. However, the gearing of the clutch wheels in the clutch wheel pairs differs from one another. Main and foot circuits 20 are similar, but with the help of a different tooth pitch, one has achieved that one clutch wheel has a few teeth - more than the other. In the illustrated embodiment, the tooth numbers are 84 and 88, so that one gear wheel at each rotation comes four teeth in front of the other.

Impulsgiveren arbejder på følgende måde:The encoder works as follows:
Drivmekanismen føres først med hånden ind i en endestilling, hvor drivhusvinduerne er lukkede. Stilleskruerne-30 24 løsnes og indstillingsringene 11 og 12 drejes, som vist i fig. 1 og 2, så at løberullen 23 på betjeningsarmen for omskifteren 19 går ind i de nøjagtigt ved siden af hinanden liggende udsnit 11a og 12a, hvorved omskifteren skifter om til sin anden koblingsstilling. I 35 denne stilling fikseres de to indstillingsringe i forhold til koblingshjulene 5 og 6. Derefter føres drivme- 144199 6 1 kanismen med hånden ind i den anden endestilling, hvor vinduerne er åbne, og den ovenfor beskrevne indstillingsoperation gentages med indstillingsringene 13 og 14 til det andet koblingshjulpar. Hermed er hele indstillings-5 arbejdet udført. Når nu drivmekanismen atter får lov til at løbe i den modsatte retning, vil den løbe, indtil de to udsnit 11a og 12a samtidig kommer til at ligge under løberullen for omskifteren 19. Det er nøjagtig den stilling, drivmekanismen først var indstillet i, og 10 hvor vinduerne var lukket. Ved fornyet igangsætning i den anden retning vil drivmekanismen igen løbe, indtil omskifteren 20 på samme måde er skiftet. Der anvendes sædvanlige styrekoblinger for trefasemotorer, så at det ikke er af interesse i enkeltheder at vide, om om-15 skifterne åbner, lukker, skifter om, eller eventuelt har flere kontakter.The drive mechanism is first inserted by hand into an end position where the greenhouse windows are closed. The adjusting screws-24 24 are loosened and the adjusting rings 11 and 12 are turned as shown in FIG. 1 and 2, so that the impeller roll 23 on the control arm of the switch 19 enters the exactly adjacent sections 11a and 12a, whereby the switch changes to its second switching position. In this position, the two adjusting rings are fixed with respect to the coupling wheels 5 and 6. Then the drive mechanism is moved by hand into the second end position where the windows are open, and the setting operation described above is repeated with the setting rings 13 and 14 to it. other clutch wheel pairs. With this the whole setting-5 work is done. Now that the drive mechanism is again allowed to run in the opposite direction, it will run until the two sections 11a and 12a simultaneously fall under the running roller of the switch 19. This is exactly the position in which the drive mechanism was first set, and 10 where the windows were closed. Upon restarting in the other direction, the drive mechanism will run again until switch 20 is similarly switched. Usual control couplings are used for three-phase motors so that it is not of interest in details to know whether the switches open, close, switch, or possibly have multiple switches.
Til en bedre forståelse af impulsgiveren henvises til fig, 3· Her er i større målestok vist de af interesse 20 værende dele af de to indstillingsringe 11 og 12 og løberullen 23 for den tilhørende betjeningsarm 22. Tandantalsforskellen mellem de to koblingshjul 5 og 6, der, som omtalt, udgør fire tænder, bevirker, at udsnittet 12a på indstillingsringen 12 efter en fuld omdrejning af 25 indstillingsringen 11 ved venstredrejning af de to koblingshjul, idet der gås ud fra den i fig. 1 viste stilling, vil være forskudt en vinkeldifferens 26 i forhold til udsnittet 11a. Denne vinkeldifferens svarer til en buelængde på fire tænder. Vinkeldifferensen må ikke væ-30 re vilkårlig lille. Den mindste værdi er, som det fremgår af fig. 3, givet ved, at det sikres, at udsparingerne 11a og 12a ikke efter den første omdrejning stadig dækker hinanden så meget, at rullen 23 endnu én gang går ned i dem. I det viste eksempel er dette netop opnået.For a better understanding of the encoder, refer to Fig. 3 · Here, on a larger scale, the parts of interest 20 of the two adjustment rings 11 and 12 and the running roller 23 of the associated control arm 22 are shown. which, as mentioned, constitute four teeth, causes the cutout 12a of the adjustment ring 12 after a full rotation of the adjustment ring 11 by turning the two coupling wheels to the left, starting from the one shown in FIG. 1, an angular difference 26 will be offset relative to the section 11a. This angular difference corresponds to an arc length of four teeth. The angle difference must not be arbitrarily small. The smallest value is as shown in FIG. 3, provided that it is ensured that the recesses 11a and 12a do not, after the first turn, still cover each other so much that the roll 23 goes down again in them. In the example shown, this has just been achieved.
35 Ganske vist overlapper udsparingerne hinanden en smule, men udsnittet 27 er så lille, at rullen 27 kun synker 144199 7 1 noget ned, uden at det kommer til nogen koblingsoperation. Efter den næste og de følgende omdrejninger overlapper udsparingerne ikke hinanden mere. Først efter mange omdrejninger nærmer udsparingerne 12a og 11a sig 5 atter hinanden fra den anden side, og efter toogtyve omdrejninger ligger udsparingerne igen ved siden af hinanden. Her ville der følgelig igen frembringes en impuls, hvis apparatet blev anvendt som impulsgiver i forbindelse med en fortløbende drivmekanisme. Når der tages 10 hensyn til nedgearingen på 2:1 fra drivakslen 3, opnås der følgelig ved anvendelsen som dobbeltendeomskifter som i det foreliggende eksempel, et maksimalt løbeområ-de på fireogfirs omdrejninger af drivakslen.35 Although the recesses overlap slightly, but the slit 27 is so small that the roller 27 only sinks down somewhat without any clutch operation. After the next and following turns, the recesses no longer overlap. Only after many turns does the recesses 12a and 11a 5 approach each other from the other side, and after twenty-two revolutions the recesses lie again next to each other. Here, therefore, an impulse would be generated again if the apparatus were used as an impulse sensor in conjunction with a continuous drive mechanism. Accordingly, when the 2: 1 downshift from the drive shaft 3 is taken into account, the use as a double-end switch, as in the present example, achieves a maximum running range of eighty-four turns of the drive shaft.
15 Udsnittene på omkredsen af indstillingsringene er længere end, hvad der kræves til en kortvarig kontaktgiv-ning af omskifteren. Herved tages der hensyn til det altid tilstedeværende efterløb af drivsystemet. Herved opnås også, at omskifteren efter udkobling af drivmeka-20 nismen af omskifteren forbliver i sin stilling.The cut-outs on the circumference of the setting rings are longer than what is required for a short-term contacting of the switch. This takes into account the ever-present aftermath of the drive system. Hereby it is also obtained that after switching off the drive mechanism of the switch the switch remains in its position.
I fig. 4- er der vist en meget kompakt impulsgiver- med tre koblingshjul 30 til 52 og tre tilhørende indstillingsringe 33 til 35, der danner en fælles omkredsflade, 25 og som hver har en udsparing. Koblingshjulenes skiveformede dele ligger ved siden af hinanden, og ensidige lejebøsninger 50a, 31a, 32a, som skiverne sidder på, er stukket ind i hinanden og herved lejret på hinanden. Den inderste lejebøsning 50a er længst, og de længere ude 30 liggende er hver et stykke forkortet. På de fremstående ender af lejebøsningerne er der lejret indstillingsringe 33 til 35, på en sådan måde, at de kan fastlåses ved hjælp af radiale stilleskruer som ved den i fig. 1 og 2 viste udførelsesform. Antallet af anvendte koblingshjul 35 kan forøges vilkårligt. Et ikke vist tastorgan må man forestille sig som ved den i fig. 1 og 2 viste udførel- 144199 8 1 sesform. Impulsgiveren kan ligeledes have en løberulle, der dog i modsætning til rullen 23 i fig. 2 snarere må have valseform. De tre koblingshjul, hvis tandantal afviger indbyrdes med nogle få tænder, står i indgreb med 5 et fælles drivtandhjul 36.In FIG. 4 shows a very compact encoder with three coupling wheels 30 to 52 and three associated adjustment rings 33 to 35 forming a common circumferential surface 25, each having a recess. The disc-shaped portions of the coupling wheels are adjacent to each other, and unilateral bearing bushes 50a, 31a, 32a on which the discs are mounted are inserted into one another and thus mounted on one another. The innermost bearing sleeve 50a is the longest and the further outwards 30 are each slightly shortened. Adjustable rings 33 to 35 are mounted on the projecting ends of the bearing bushes in such a way that they can be locked by means of radial adjusting screws as in the one shown in FIG. 1 and 2. The number of clutch wheels 35 can be increased arbitrarily. A key not shown may be imagined as in the one shown in FIG. 1 and 2 are shown in the embodiment. The impulse transducer may also have a running roller, which, in contrast to the roller 23 in FIG. 2 should rather have a roll shape. The three clutch wheels, the number of teeth differing with a few teeth, are engaged by a common drive gear 36.
En dobbeltendeomskifterkobling med et meget stort løbe-område kan opnås ved tilføjelse af en med stiplede linier antydet spejlvendt koblingsmekanisme 37. Også ved 10 denne kobling ligger samtlige koblingshjul ved siden af hinanden og kan drives af det fælles drivtandhjul 36.A double-end switching coupling with a very large running area can be obtained by adding a mirrored coupling mechanism 37 with dotted lines.
