Description
Getriebe zur Hin- und Herbewegung eines Schlittens Die Erfindung bezieht sich auf die an sich bekannten Getriebe zur Hin- und Herbewegung eines Schlittens durch eine in derselben Richtung umlaufende Kette. Das Neue besteht darin, daß die Achsen der Kettenräder, die in bekannter Weise bei Umschaltgetrieben als Kupplungsglieder zwischen -der Kette und dem Schlitten dienen, am Schlitten fest angeordnet sind und die Kettenräder beim Auftreffen des Schlittens auf die Anschläge unter Vermittlung bekannter Getriebeteile durch Backen gebremst werden. Dadurch wird gegenüber dem Bekannten erreicht, daß die Umschaltung des Getriebes nicht nur sanft und ohne Stöße erfolgt, sondern auch der Verschleiß des Treibgliedes verhindert wird.Transmission for reciprocating a carriage The invention relates to on the known gears for reciprocating a slide by a chain rotating in the same direction. The new thing is that the Axles of the sprockets, which are used in a known manner in the case of change-over gearboxes as coupling links Serve between -the chain and the carriage, are fixedly arranged on the carriage and the chain wheels when the carriage hits the stops under mediation known gear parts are braked by jaws. This is opposite to the Acquaintances achieved that the gear change is not only gentle and without jolts takes place, but also the wear of the drive link is prevented.
Ein Umschaltgetriebe gemäß der @ Erfindung ist in Abb. x in Gesamtansicht, teilweise im Schnitt veranschaulicht. Abb. 2 zeigt die im gehäuseartigen Gleitstück wirksamen Einzelteile.A changeover transmission according to the invention is shown in Fig. X in an overall view, partially illustrated in section. Fig. 2 shows the in the housing-like slider effective items.
In dem dargestellten Ausführungsbeispiel erhalten die Kettenrollen a, b der endlosen Gelenkkette c ihren Antrieb durch eine Riemscheibe d und sind beide Trums der Kette durch ein gehäuseartiges Gleitstück e hindurchgeführt, in welchem ein Kettenrollenpaar f, g angeordnet ist, von denen die Rolle f in das obere und die Rolle g in das untere Tram der Gelenkkette c eingreift. In dem Gleitstück e ist mit dem Hebel l auf gleicher Achse die Exzenterscheibe k gelagert, die auf zwei Bremsklötze i, k für die Kettenrollen f, g einwirkt. Bei der schrägen Einstellung des Hebels l drückt das Exzenter h auf einen der Bremsklötze i, k, so daß eine der beiden Kettenrollen f, g festgehalten und das Gleitstück e von einem der beiden Kettentrums c in dessen Bewegungsrichtung zwangläufig mitgenommen wird. Stößt nun der Hebel l am Ende der Bahn gegen einen der beiden verstellbaren Anschläge m, n, so wird er von diesen umgelegt, wodurch die bisherige gebremste Kettenrolle gelöst und die bisher frei umlaufende Kettenrolle gebremst wird. Dies hat die Wirkung, daß das gehäuseartige Gleitstück e in entgegengesetzter Richtung wie vorhin so weit mitgenommen wird, bis der Hebel l gegen den anderen Anschlag stößt und sich der soeben erläuterte Vorgang wiederholt.In the illustrated embodiment, the chain rollers a, b of the endless articulated chain c are driven by a pulley d and both strands of the chain are passed through a housing-like slider e, in which a pair of chain rollers f, g is arranged, of which the roller f in the upper and the roller g engages in the lower tram of the articulated chain c. In the slider e, the eccentric disk k is mounted with the lever l on the same axis, which acts on two brake pads i, k for the chain rollers f, g. When the lever l is set at an angle, the eccentric h presses one of the brake pads i, k, so that one of the two chain rollers f, g is held and the slider e is inevitably carried along by one of the two chain strands c in its direction of movement. If the lever l hits one of the two adjustable stops m, n at the end of the path, it is turned over by these, whereby the previous braked chain roller is released and the previously freely rotating chain roller is braked. This has the effect that the housing-like slider e is carried along in the opposite direction as before until the lever l hits the other stop and the process just explained is repeated.
