Description
Die Erfindung betrifft einen winkclbeweglichen Rollbalg, insbesondere zur Abdichtung von Drehgelenkkupplungen, bestehend aus einem elastisch verformbaren Werkstoff, beispielsweise Gummi, mit einem äußeren Ring zur dichten Verbindung mit dem äußeren Kupplungsteil der Drehgclenkkupplung, einem inneren Ring zur dichten Verbindung mit der Gelenkwelle, einem diese beiden Ringe verbindenden Rollabschnitt, sowie einem den Rollbalg schützenden Panzerring, der einen radialen Abschnitt aufweistThe invention relates to an angularly movable rolling bellows, in particular for sealing swivel joint couplings, consisting of an elastically deformable material, such as rubber, with a outer ring for tight connection with the outer coupling part of the rotary joint coupling, an inner one Ring for tight connection with the cardan shaft, a rolling section connecting these two rings, and an armored ring protecting the rolling bellows and having a radial section
Eine rollbalgähnliche Abdichtung mit den obigen Merkmalen ist bereits aus der DE-PS 18 17 195 bekanntgeworden, die eine Gleichlaufverschiebegelenkkupplung mit sehr kleinen Deugungswinkeln für den Antrieb bei Walzengerüsten zeigt, bei welcher der äußere Ring durch ein Abdeckblech geschützt ist, das einen lediglich zum frontalen Abdecken des äußeren Ringes und seiner Befestigung dienenden, radial vorspringenden Abschnitt aufweist, der jedoch nicht als Anschlag zum Schutz einer Überbeanspruchung des Rollabschnittes dient. Es kann daher bei einem etwas stärkeren Auslenken der beiden Kupplungsteile gegeneinander vorkommen, daß die die Wölbung bzw. Schleife oder Falte des Rollabschnitts zwischen sich enthaltenden Schenkel diese Falte oder Wölbung plattdrücken oder zusammenquetschen, was schon nach kurzem Gebrauch eine Zerstörung der rollbalgartigen Abdichtung zur Folge haben könnte.A bellows-like seal with the above features is already from DE-PS 18 17 195 became known that a constant velocity joint coupling with very small Deugungswinkel for the Drive in roll stands shows in which the outer ring is protected by a cover plate, the one serving only for the frontal covering of the outer ring and its fastening, radial Has protruding portion, but not as a stop to protect against overstressing of the Rolling section is used. It can therefore with a somewhat stronger deflection of the two coupling parts against each other happen that the curvature or loop or fold of the roll section between them containing legs flatten this fold or bulge or squeeze it together, which is already after brief use could destroy the bellows seal.
Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Anordnung von der Art, wie sie in der DE-PS 18 17 195 beschrieben ist, so zu verbessern, daß nicht nur ein optimaler Schutz gegen jede Art von mechanischer Beschädigung von außen mit einfachen Mitteln erreicht wird, «ondern bei guter Winkelbeweglichkeit auch insofern eine wesentliche Erhöhung der Lebensdauer bewirkt wird, indem man dem Vorsprung am Panzerring oder Abdeckblech die Funktion eines Anschlag- und Distanzelementes zuordnet, das verhindert, daß die Falte oder Wölbung plattgequetscht und überbeansprucht wird.The invention is based on the object of providing an arrangement of the type as shown in the DE-PS 18 17 195 is described to improve so that not only optimal protection against any kind of mechanical damage from the outside is achieved with simple means, "ondern with good angular mobility also to the extent that a significant increase in service life is achieved by removing the projection Assigns the function of a stop and spacer element on the armored ring or cover plate, which prevents that the fold or bulge is squashed flat and overstressed.
Die obige Aufgabe wird erfindungsgemäß dadurch gelöst, daß dieser radiale Abschnitt als Anschlag so ausgebildet und angeordnet ist, daß eine Mindestkrümmung des Rollabschnitts nicht unterschritten werden kann.The above object is achieved according to the invention in that this radial section acts as a stop is designed and arranged that a minimum curvature of the rolling section is not undershot can.
Die erfindungsgemäße Abdichtung hai den Vorteil eines einfachen und kostengünstigen Aufbaus vor allem, weil man jetzt für viel größere Beugungswinkel mit weniger Abdichtungsmaterial und weniger Schmierfett auskommen kann. Darüber hinaus ist die Lebensdauer der Abdichtung nunmehr wesentlich höher, einerseits, weil durch die Wirkung des zum inneren Ring hinThe seal according to the invention has the advantage of a simple and inexpensive construction, especially because you can now look for much larger angles of deflection with less sealing material and less grease can get along. In addition, the service life of the seal is now much longer, on the one hand, because through the action of the towards the inner ring
ig gerichteten und mit diesem oder mit einer Panzerung desselben zusammenarbeitenden Vorsprungs am Panzerring als Anschlag und als Abstandshalterung ein Plattdrücken oder Zusammenquetschen der Falte oder Wölbung vermieden wird, und andererseits auchig directed and with this or with armor the same cooperating projection on the armored ring as a stop and as a spacer Flattening or squeezing the fold or bulge is avoided, and on the other hand also
is deswegen, weil Beschädigungen der Abdichtung durch Steinschlag oder Nagetiere besonders gut vermieden werden können.is because of the damage to the seal Rockfall or rodents can be avoided particularly well.
