Opfindelsen angår et kædedrev af den i kravets indledning anførte art.The invention relates to a chain drive of the kind specified in the preamble of the claim.
Ved kædedrev med endeløs kæde, der drives maskinelt, holdes kæden konstant i strakt stilling ved hjælp af en eller flere kædestrammere for at opnå et roligt kædeløb. Selv i en kendt udførelsesform, hvor en endeløs kæde drives i en kædekanal (Kettenkanal-Kreisfordere der Rheinstahl Aufziige GmbH), er kanalen udstyret med en spændestation til sikring af ensartet kædestramning og udligning af ændringer af kædelængden. Anvendelsen af kædestrammere eller strammestationer fordyrer selvsagt fremstillingen og øger derhos antallet af dele, der kræver vedligeholdelse, således at også driften fordyres.For endless chain driven chain drives, the chain is constantly held in a straightened position by one or more chain tensioners to achieve a smooth chain run. Even in a known embodiment, where an endless chain is driven in a chain channel (Kettenkanal-Kreisfordere der Rheinstahl Aufziige GmbH), the channel is equipped with a tensioning station for ensuring uniform chain tensioning and equalizing changes in chain length. The use of chain tensioners or tensioning stations, of course, increases the cost of manufacturing and thereby increases the number of parts requiring maintenance, so that the operation is also expensive.
Ved kendte drev af den omhandlede art med kædeetrammer drives kæden altid ved træk, hvorved de samme fladeafsnit på tilstødende kædeled praktisk talt altid vil ligge an mod hinanden, og der vil ikke ske nogen flytning af det nødvendige spillerum mellem leddene - bortset fra en ubetydelig ændring under gennemløbet af en omstyringsstrækning, hvilket bevirker, at smøring netop af leddedes påvirkede fladeafsnit kun er mulig i utilstrækkeligt omfang, og at der derfor opstår øget slitage.For known drives of the type in question with chain fasteners, the chain is always driven by features, whereby the same surface sections of adjacent chain links will practically always abut one another, and no necessary clearance between the joints will occur - except for a slight change during the course of a forwarding stretch, which means that lubrication of precisely the affected area of the joint is only possible to an insufficient extent, and therefore increased wear.
Fra DD-PS nr. 96 316 kendes endvidere et kædedrev med uforbundne kædeenheder, og hvor kæden i hele sin længde drives enten ved skub- eller ved trækpåvirkning.Furthermore, from DD-PS No. 96 316 a chain drive with unlinked chain units is known, in which the chain is operated for its entire length either by pushing or by pulling action.
Det er opfindelsens formål at anvise et kædedrev af den i kravets indledning anførte art, der er således udformet, at kædestrammeren eller strammestationen kan udelades, uden at der sker nogen forringelse af kædens rolige løb og således, at smøring sker i fuldt tilstrækkeligt omfang.It is an object of the invention to provide a chain drive of the kind set forth in the preamble of the claim, which is designed so that the chain tensioner or tensioning station can be omitted without any deterioration of the quiet running of the chain and so that lubrication takes place to a sufficient extent.

Dette opnås ifølge opfindelsen ved de i kravets kendetegnende del anførte foranstaltninger.This is achieved according to the invention by the measures specified in the characterizing part of the claim.
I modsætning til hvad tilfældet er ved kendte drev, er ifølge opfindelsen kædens drift opdelt i en trykzone og en trækzone med en fastliggende overgang mellem de to zoner. Derved bliver kædeleddene set i bevægelsesretningen påvirket tosidigt og ikke blot ensidigt, hvilket med andre ord vil sige, at leddenes bæreflader belastes henholdsvis aflastes skiftevis til den ene og den anden side. Mellemrummene mellem leddene, der altid vil være tilstede, og som er nødvendige til optagelse af smøremidlet, underkastes således skiftevise ændringer, hvorved smøremidlet fortrænges tilsvarende skiftevis til den ene og den anden side. Man ville også kunne beskrive dette med, at kædeleddene "ånder".Contrary to known drives, according to the invention, the operation of the chain is divided into a pressure zone and a drag zone with a fixed transition between the two zones. In this way, the chain links are viewed in the direction of movement bilaterally and not simply unilaterally, in other words, that the supporting surfaces of the joints are loaded or relieved alternately to one and the other side. Thus, the gaps between the joints, which will always be present and necessary to receive the lubricant, are subjected to alternate changes, thereby displacing the lubricant accordingly alternately to one and the other side. You could also describe this with the chain links "breathing".
I modsætning til kædedrev, hvor kæden konstant holdes strakt ved hjælp af kædestrammere, undgås her selv ved ekstreme og/eller ugunstige belastninger enhver risiko for utilstrækkelig smøring.Unlike chain drives, where the chain is constantly stretched by means of chain tensioners, even at extreme and / or unfavorable loads, there is no risk of insufficient lubrication.
Opfindelsen forklares nærmere i det følgende under henvisning til tegningen, der skematisk viser et kædedrev ifølge opfindelsen set fra oven.The invention is explained in more detail below with reference to the drawing, which schematically shows a chain drive according to the invention seen from above.
Det viste kædedrev omfatter en endeløs kæde 1, der i hele sin udstrækning er indesluttet i en kædekanal 2, og som drives ved hjælp af drivorganer 3. Kædens led 4, navnlig disses i bevægelsesretningen forreste ende 5 styres i kædekanalen 2. Kædens bevægelse sker i den med pilen viste retning, og i det afsnit af kæden, der befinder sig efter drivorganerne 3, skubber den forreste ende 5 af leddene mod den bageste ende 6 af det nærmest foran liggende led, og følgelig er i hvert led spillet større fremad end bagud.The chain drive shown comprises an endless chain 1, which is fully enclosed in a chain channel 2 and which is driven by drive means 3. The chain link 4, in particular its forward end 5 in the direction of movement of the chain channel 2. The movement of the chain takes place in in the direction shown by the arrow, and in the section of the chain which is located after the driving means 3, the front end 5 of the joints pushes towards the rear end 6 of the closest joint, and consequently in each joint the play is greater forward than backward .

DK 152861BDK 152861B
Det modsatte er tilfældet i det afsnit af kædekanalen 2, der ligger før drivorganerne 3. Her trækkes hvert led af det nærmest foran liggende led, således at i hvert led er spillet større bagud end fremad. Her findes smøremidlet derfor hovedsageligt i leddets bageste del, medens det efter drivorganerne 3 skifter til den forreste del, og derved sikres en stadig, tilstrækkelig smøring og en ensartet slitage af leddenes flader.The opposite is the case in the section of the chain channel 2 which lies before the driving means 3. Here, each link is pulled by the closest link, so that in each link the play is greater backward than forward. Here, therefore, the lubricant is found mainly in the rear part of the joint, while it switches to the front part after the driving means 3, thereby ensuring a continuous, sufficient lubrication and uniform wear of the joints' surfaces.
Overgangen fra "skubbezonen" til "trækzonen", d.v.s. fra det sammenskubbede kædeafsnit til det strakte kædeafsnit ligger ifølge tegningen på det med 7 viste sted, men overgangsstedet kan forskydes alt efter driftsbetingelserne, f.eks. afhængigt af belastningens størrelse. Endvidere er i denne sammenhæng den indbyrdes afstemning af kædens og kædekanalens længde afgørende, hvorved, som foran nævnt, kæden hverken skal være strakt eller sammenskudt i statisk tilstand. Selv når disse forhold er taget i betragtning, er det muligt at vælge overgangsstedets placering således, at de enkelte kædeled belastes i lige lange perioder af træk henholdsvis tryk, eller således at de gennemløber lige mange krumninger under træk som under tryk.The transition from the "push zone" to the "pull zone", i.e. according to the drawing at the location shown by 7, from the shoved chain section to the stretched chain section, the transition point can be shifted according to the operating conditions, e.g. depending on the size of the load. Furthermore, in this context, the matching of the length of the chain and the chain channel is crucial, whereby, as mentioned above, the chain must not be stretched or pushed together in a static state. Even when these conditions are taken into account, it is possible to choose the location of the transition point so that the individual chain links are stressed for equal periods of pull or pressure respectively, or so that they undergo as many curves under pull as under pressure.
Som følge af disse foranstaltninger løber kæden, også selv om den ikke er spændt, fuldstændig roligt i kædekanalen 2, og kædens led befinder sig stadigt i en stabil, styret stilling, hvor leddene, alt efter kanalens forløb og alt efter om det drejer sig om en "trykzone" eller om en "trækzone", støttes skiftevis på den ene og den anden side i kanalen. Selvsagt kan kanalen have enhver ønsket længde og form, ligesom der eventuelt kan findes flere adskilte drivorganer.As a result of these measures, the chain, even if not tensioned, runs completely still in the chain channel 2 and the chain link remains in a stable, controlled position where the joints, depending on the course of the channel and depending on a "pressure zone" or a "pull zone" is alternately supported on one and the other side of the channel. Of course, the duct can have any desired length and shape, as well as possibly several separate drive means.
Kæden kan ligeledes have forskellig udformning, f.eks. med kugleled eller med kun begrænset svingelige led,The chain may also have different designs, e.g. with ball joints or with only limited pivotal joints,
DK 152861 BDK 152861 B
4 ligesom leddene uafhængigt af deres udformning iøvrigt kan have rullende eller glidende ledeorganer.4, as the joints, independently of their design, may otherwise have rolling or sliding guide members.
Også kanalen kan have forskellige udformninger. Således kan kanalen ved en drivkæde være helt lukket og ved en transportkæde have en eller flere spalter.Also the channel may have different designs. Thus, in a drive chain, the channel may be completely closed and have a slot (s) at one transport chain.
Uden derved at begrænse det omhandlede kædedrevs anvendelsesområde bemærkes, at dets fordele navnlig kommer til deres ret ved transportkæder, der ofte har en betydelig længde og et kompliceret forløb. En særligt foretrukket anvendelse af kædedrevet ifølge opfindelsen findes i forbindelse med avistransportører.Without limiting the scope of the chain drive in question, it should be noted that its advantages come in particular to their rights in transport chains, which often have a considerable length and a complicated course. A particularly preferred use of the chain drive according to the invention is found in connection with newspaper conveyors.
Det beskrevne kædedrev er i vidt omfang uafhængigt af kædeforløbet og kædens længde. Følgelig kan kædekanalen, når den er sammensat af flere dele, nemt ændres med heisyn til længde og form. Der vil kunne anvendes strækbare kanalelementer eller dele, der nemt kan forbindes med og skilles fra hinanden. Tilsvarende gælder også udformningen af kædens led.The chain drive described is largely independent of the chain process and the length of the chain. Consequently, the chain channel, when composed of several parts, can be easily changed with height and shape lift. Extensible duct elements or parts that can be easily connected and separated can be used. The same applies to the design of the chain link.
Kædedrevet vil også med fordel kunne anvendes som drivkæde, idet kæden helt kan indesluttes i kanalen og arbejde under optimale smørebetingelser, f.eks. løbe i et oliebad. Selv kædehjul eller andre drivorganer befinder sig derved i et lukket hus, hvorfra alene driv-akselen henholdsvis akselen til kraftoverføring må rage ud med fornøden tætning.The chain drive can also advantageously be used as a drive chain, since the chain can be completely enclosed in the channel and work under optimal lubrication conditions, e.g. run in an oil bath. Thus, even sprockets or other drive means are in a closed housing, from which only the drive shaft or the shaft for power transmission must protrude with the necessary seal.
Iøvrigt kan kædekanalen alt efter kædens beskaffenhed have afbrudte områder navnlig i "trækzonen". En stedvis eller i hele sin længde opspaltet kædekanal gør det muligt - eventuelt ved iøvrigt uændret kædeforløb -at anbringe organerne til drift eller til kraftoverføring på ønskede steder og f.eks. at forankre sådanneMoreover, depending on the nature of the chain, the chain channel may have interrupted areas, especially in the "pull zone". A chain channel, which is split up or in its entire length, makes it possible - possibly by means of otherwise unchanged chain course - to place the means for operation or for transmission in desired places and e.g. to anchor such
DK 152861 BDK 152861 B
5 organer ved at fastgøre dem til kædekanalen. Derved udvides kædedrevets anvendelighed, navnlig når kædekanalen består af flere elementer, der nemt kan sammenkobles. I hvert fald kræves der kun forholdsvis lette holdeorganer for kædekanalen, og tunge fundamenter er unødvendige.5 bodies by attaching them to the chain channel. This extends the usefulness of the chain drive, especially when the chain channel consists of several elements which can be easily connected. In any case, only relatively light retaining means are required for the chain channel, and heavy foundations are unnecessary.
Ved alle udførelsesformer for kædedrevet ifølge opfindelsen opnås et rykløst forløb, først og fremmest ved moderate hastigheder, og dette til trods for, at spillet i leddene ikke, i modsætning til hvad tilfældet hidtil har været, søges elimineret f.eks. ved hjælp af kædestrammere. Tværtimod -. Ved kædedrevet ifølge opfindelsen udnyttes det uundgåelige spil i leddele, der hidtil er betragtet som en ulempe, idet leddenes foran nævnte "ånden" øger kædens bæreegenskaber og levetid.In all embodiments of the chain drive according to the invention, a non-slip process is achieved, first and foremost at moderate speeds, and this despite the fact that the play in the joints is not, unlike the case so far, sought to be eliminated e.g. using chain tensioners. On the contrary -. In the chain drive according to the invention, the inevitable play is utilized in hinge parts, hitherto regarded as a disadvantage, in that the "spirit" of the joints mentioned above increases the carrying and life characteristics of the chain.
