Description
Rundgliederkette mit Flachschubglieler und Flachschubkettenrad für Kratzerförderer sowie für Raupenfahrzeuge.Round link chain with flat push link and flat push sprocket for Scraper conveyors and for crawler vehicles.
Die Erfindung bezieht sich auf eine aundgliederkette für Kratzerförderer insbesondere für Einkettenförler, sowie für Raupenfahrze ue0 Bei den bekannten Rundgliederketten legen sich die in das Kettenrad einlaufenden flachen Kettenglieder in die Taschen des Kettenrades.The invention relates to a final link chain for scraper conveyors especially for single chain conveyors, as well as for caterpillar vehicles ue0 With the known round link chains the flat chain links that run into the sprocket are placed in the pockets of the sprocket.
Nachteilig wirkt sich auf die kundgliederkette die kleine Kettentrommel-Schubfläche aus was eine hohe spezifische Flächenpressung zur Folge hat . Dies ist mit die Ursache von Beschädigungen der flachen Glieder an den Außenrundungen.The small chain drum thrust surface has a disadvantageous effect on the customer link chain from which a high specific surface pressure results. This is one of the reasons of damage to the flat links on the outer curves.
Die Folge ist, da? die Rundgliederketten an Arbeitsvermögen verlieren und vorzeitig aus dem Betrieb gezogen werden.The consequence is there? the round link chains lose their working capacity and be withdrawn from operation prematurely.
Außerdem Nachteilig ist, daß durch die Querkraftkomponente federnde nach auPenausweichende Verhalten der Zahntaschen es notwendig macht die Zahntaschenflanken zu verstärken.Another disadvantage is that resilient due to the transverse force component the tooth pocket flanks make it necessary for the tooth pocket flanks to evade the outside to reinforce.
Die Erfindung hat sich darin die Aufgabe gestellt eine Rundgliederkette für Kratzerförderer sowie haupenfahrzeuge zu schaffen die die vorgenannten techn. Mängel der bisher bekannten Ausführungen beseitigt und mit vergleichsweise einfachen Mitteln die Lebensdauer dieser Ketten und das Antriebssystem dadurch zu verbessern.The invention has set itself the task of a round link chain for scraper conveyors as well as main vehicles to create the aforementioned techn. Defects of the previously known designs eliminated and with comparatively simple ones Means to improve the service life of these chains and the drive system.
Dieses Ziel wird durch iie ERfindung dadurch erreicht, daß die flach auf das Kettenrad auflaufenden Kettenglider mit einer größeren Breite und mittiger Führung in die Zähne des kettenrades eingreifen.This goal is achieved by the invention in that the flat Chain gliders running onto the sprocket with a larger width and more centered Engage the guide in the teeth of the sprocket.
Das besondere Merkmal ist, daß die Eingriffsflächen von flachliegenden Kettengliedern und RettentrommeS zähne eine größere Breite an den Schubflächen gegenüber den normalen Rundgliederkettengliedern aufweisen.The special feature is that the engagement surfaces of flat lying Chain links and rescue drums have a larger width on the thrust surfaces opposite the normal round link chain links.
Die Zahnform des Kettenradesilt für diese Rundgliederkette mit Flachschubglieder ist so ausgebidet, daß die Außenrundungen der Flachschubglieder mittig im Kettenrad geführt werden, so daß ein seitliches ausweichen nicht gegeben ist.The tooth shape of the sprocket applies to this round link chain with flat thrust links is designed so that the outer curves of the flat thrust links are centered in the sprocket be guided so that a sideways evasion is not given.
Durch die vorgeschlagene Ausbildung der flachen Flachschubglie der ist lie Auflagefläche wesentlich an der Kraft übertragungsstelle vergrößert, d.h. der spez. Flächendruck wird kleiner.The proposed design of the flat Flachschubglie the contact surface is significantly enlarged at the point of force transmission, i.e. the spec. Surface pressure is getting smaller.
Außerdem wird die Teilung gegenüber den herkömmlichen Rundglederketten wesentlich genauer.In addition, the division is compared to the conventional round link chains much more accurate.
Der Ablauf von Kette und Kettenrad ist ähnlich dem Ablauf einer Rollenkette, mit lem Unterschied das beliebig große Kurven gefahren werden können.The sequence of chain and sprocket is similar to the sequence of a roller chain, with the difference that curves of any size can be driven.
Ein Ausführungsbeispiel ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben.An embodiment is shown in the drawings and will described in more detail below.
Es zeigen Fig. 1 das flach aufliegende Kettenglied im Kettenrad Fig. 2 Schnitt durch das Kettenrad und durch die Kette Fig. 3 Schnitt eines Kettenradzahnpaaresmit Eingriff des Flachschubgliede8.1 shows the chain link lying flat in the chain wheel Fig. 2 Section through the chain wheel and through the chain Fig. 3 Section through a pair of chain wheel teeth Engagement of the flat thrust link 8.
Fig. 4 Schnitt eines Kettenradzahnes mit Eingriff eines Flachschubgliedes.Fig. 4 section of a sprocket tooth with engagement of a flat push member.
Das Flachschub-Kettenglied 1 ist an den Kettenangriffsflächen mit je zwei halbrunden Schubflächen 3, 3' bzw. 3'', 3''' versehen. Die Schubflächen horizental rechtwinklich oder pfeiförmig zur Laufrichtung der Kette ausgebildet. Dagegen haben die hochstehenden Kettenglieter 2 die bekannten Ausführungen der handelsüblichen Rundgliederketten.The flat thrust chain link 1 is on the chain attack surfaces with two semicircular sliding surfaces 3, 3 'or 3 ", 3"'. The push surfaces horizontally at right angles or whistle-shaped to the running direction of the chain. In contrast, the upright chain links 2 have the known versions of the commercially available ones Round link chains.
Die Kraftübertragung vom Kettenrad 4 auf die Kette erfolgt von den parallel angeordneten Mitnahmezähnen 5, 5! bzw.The power transmission from the sprocket 4 to the chain is carried out by the driving teeth 5, 5 arranged in parallel! respectively.
5", 5 " ' die den wagerechten Ketten-Flachschubglidern sngepaßt sind.5 ", 5" 'which are fitted to the horizontal chain flat slide gliders.
Zugleich haben die Mitnahmezähne 5, 5' bzw, 5", 5 " ' des Kettenrades 4 je eine Abschrägung 6, 6' bzw. 6", 6"' zur Kettenlaufmitte hin, die dem Flachschubglied 1 angepaßt sind und zur seitlichen Führung dienen.At the same time, the driving teeth have 5, 5 'or 5 ", 5"' of the sprocket 4 each a bevel 6, 6 'or 6 ", 6"' towards the middle of the chain run, which the flat push link 1 are adapted and are used for lateral guidance.
Allgemein kann angenommen werden, daß diese Rundglieder-Kettenausführung den steigenden Anforderungen und dem Ablauf Kette - Kettenstern gerecht wird, PatentansprücheIt can generally be assumed that this round link chain design the increasing demands and the sequence chain - chain star meets patent claims
