Description
die Erfindung betrifft eine Über lastungskupplung, wie sie insbesondere für den Eimerkettantrieb von Baggern, Absetzern od. dgl., für den antrieb von Kranen, kabelkranen, Nahförderern, Transportbändern. Aufzügen od. dgl. verwendet wird. Derartige Kupplungen schalten bei Erreichen eines bestimmten, meist wahlweise festlegbaren höchstzulässigen Drehmomentes selbsttätig aus. Es sind derartige Kupplungen bekannt, bei denen Rastrollen od. dgl. der einen Kupplungshälfte in an der anderen Kupplungshälfte vorgesehene Mitnehmerkerben lösbar eingreifen. Die kraftschlüssige Verbindung zwischen den beiden Kupplungsteilen wird durch die Rolle od. dgl. hergestellt. Bei unzulässiger Vergrößerung des Antriebsdrehmomentes und damit der auftretenden Tangenticalkraft springt die Rastralle aus der durchweg im Gehäuse des einen Kupplungsteiles befindlichen Raste hieraus; die Kupplung ist gelöst.The invention relates to an overload clutch, as in particular For the bucket chain drive of excavators, skimmers or the like, for the drive of cranes, cable cranes, local conveyors, conveyor belts. Elevators or the like. Is used. Such Clutches switch when a certain, usually optionally determinable, is reached maximum permissible torque off automatically. Such couplings are known where locking rollers od. The like. One coupling half in on the other coupling half detachably engage provided driver notches. The positive connection between the two coupling parts is produced by the roller or the like. In the case of impermissible Increasing the drive torque and thus the tangentical force that occurs the locking claw jumps out of the one located throughout the housing of one coupling part Raced out of here; the clutch is released.
Die l>ekannten Kupplungen haben den Nachteil, daß beim Ausrasten und beim Wiedereinrasten durch die schlagarrtigen bzw. ruchkartigen Bewegungen sehr große Beschleunigungs- bzw. Verzögerungskräfte auftreten, die die einzelnen Teile der Kupplung mechanisch stark beanspruchen und unter Umständen zur Zerstörung der Kupplung führen können. The unfamiliar clutches have the disadvantage that when they disengage and when re-engaging through the jolting or odorous movements very much large acceleration or deceleration forces occur that affect the individual parts mechanically stress the coupling and possibly destroy the Clutch can lead.
Die Erfindung hat sich die Aufgabe gestellt, die Nachteile der bekannten Rastkupplungen zu vermeiden. Sie besteht darin, daß die Mitnehmerkerben unter Zwischenschaltung eines elastischen Werkstoffes mit dem Gehäuse verbunden sind. Dadurch werden die hohen Beschleunigungs- bzw. Verzögerungskräfte weitgehend abgefedert und aufgefangen. The invention has the task of addressing the disadvantages of the known Avoid locking couplings. It consists in the fact that the driver notches are interposed an elastic material are connected to the housing. This will make the high acceleration and deceleration forces are largely cushioned and absorbed.
Um den erfindungsgemäßen Zweck noch zu vervollkommnen, schlägt die Erfindung weiterhin vor, die Rastrollen od. dgl. nicht starr zu führen. Vielmehr können die Rastrollen od. dgl. in in Mitnahmerichtung nachgiebigen Führungen geführt sein. Bei einer derartigen Führung können die Rastrollen den auftretenden Drücken beim Ein- bzw. Ausrasten seitlich elastisch ausweichen, so daß die verhältnismäßig großen Besehleunigungs- bzw. Verzögerungskräfte aufgefangen werden. Eine einfache Ausführungsform der Erfindung besteht darin, daß die Führungshnen der Rastrollen od. dgl. durch die Enden einersiets $federned gegeneinander abgestützt sind und anderseits an je einem Anschlag anliegen. In order to perfect the purpose of the invention, suggests The invention also provides for the locking rollers or the like not to be rigidly guided. Much more the locking rollers or the like can be guided in guides that are flexible in the driving direction be. With such a guide, the locking rollers can withstand the pressures that occur when engaging or disengaging laterally elastically evade, so that the relatively large acceleration or deceleration forces are absorbed. A simple one Embodiment of the invention is that the guide teeth of the locking rollers od. The like. Are supported against one another by the ends of a springy and on the other hand, each rest against a stop.
Bei einer derartigen Führung kann die Rastrolle aus der Ruhelage seitlich um ein geringes herausgedrückt werden. in der Zeichnung ist eine Ausführungsform der Erfindung schematisch dargestellt, und zwar zeigt Abb. 1 eine Draufsicht und Abb. 2 einen Schnitt entlang der Linie 1-1 der Ah). 1.With such a guide, the locking roller can move laterally out of the rest position to be squeezed out a little. in the drawing is an embodiment of the invention shown schematically, namely Fig. 1 shows a plan view and Fig. 2 a section along the line 1-1 of the Ah). 1.
Bei der in den Al)lildungen dargestellten Lage der Kupplung liegen die beiden Rollenrasten 1 des KUpplungsinnenteiles 2 in den Mitehmerkertben 3 des Kupplungsaußenteiles 4. Die Resten 3 liegen dabeoi nicht unmittelbar dem Kupplungsgehäuse 4 an, vielmehr befindet sich zwischen den Rasten 3 und dem Kupplungsgehäuse 4 eine hochelastische Zwischenschicht 5. In the position of the coupling shown in the drawings the two roller detents 1 of the inner coupling part 2 in the driver notches 3 of the Outer clutch part 4. The remnants 3 are not immediately adjacent to the clutch housing 4 on, rather there is one between the notches 3 and the clutch housing 4 highly elastic intermediate layer 5.
Die Rollenrasten I werden durch die Federn 6 in Rastmittenrichtung gedrückt. Seitlich sind die Rollen rasten zwischen den freien Enden 7 der Hebel 8 geführt, die um die. achsen 9 drehbar sich, und deren seide anderen freien Enden durch die Spannfedern 10 gegeneinader absgestützt sind. The roller detents I are by the springs 6 in the detent center direction pressed. The side of the rollers are locked between the free ends 7 of the levers 8 led to the. axes 9 rotatable, and their silk other free ends are supported against each other by the tension springs 10.
Dabei liegen in Ruhestellung die Hebet gegen die Knaggen 11 und 12 an.In the rest position, the lifters lie against the lugs 11 and 12 at.
Klinken die Rollen 1 aus den Rasten 2 aus, dann bewegen sie sich auf der Laufbahn 13 des Kuppjungsehäuses 4, bis die Massenkräfte durch die Bremsen des Getriebes vernidhtet sind. Durch die besondere Ausbildung der Rastkupplung können selbst l>ei schnellaufenden Kupplungen die beim aus und Einrasten auftretenden Beschleunigungs-und Verzögerungskräfte in solchen Grenzen gehalten werden, daß die Kupplungen nicht beschädigt werden. If the rollers 1 disengage from the notches 2, they move on the raceway 13 of the Kuppjungsehäuses 4 until the inertia forces through the brakes of the gearbox are sewn. Due to the special design of the locking coupling, you can even with high-speed clutches the ones that occur when disengaging and engaging Acceleration and deceleration forces are kept within such limits that the Couplings are not damaged.
