Description

Elastische Wellenkupplung mit zwischen den Kupplungsscheiben als Ganzes in zusammengedrücktem Zustand einfügbarem Gummikörper Es sind elastische Wellenkupplungen mit zwischen den Kupplungsscheiben :als Ganzes in zusammengedrücktem Zustand einfügbarem Gummikörper bekannt. Dieser besteht teils aus einem; oder zwei festschraubbaren Gummikörpern, die in der Mitte kegelförmigen und .am Innen- und Außenrand ebenen Querschnitt aufweisen. Am Innen- und Außenrand sind Metallringe eingespannt oder aufvulkanisiert, die auf den Wellenflanschen zentriert und mit diesen durch Schrauben verbunden sind. Da die Einspannräder starr sind und etwa die Hälfte des Gummikörperquerschnittes beanspruchen, verbleibt als wirksamer nachgiebiger Teil nur etwa die Hälfte des Gummikörpers. Dadurch wird aber die Elastizität und Biegsamkeit der Kupplung so stark herabgesetzt, daß das Einfügen des Gummikörpers zwischen den Wellenflanschen eine besondere Vorrichtung erforderlich .macht. Bei den Kupplungen mit zwei kegeligen Gummikörpern sind letztere in der Mitte :durch Blechringe und Scheiben umkleidet und durch Schrauben oder Niete verbunden. Durch die starren Blechringe usw. werden jedoch die Elastizität und Biegsamkeit der Gummikörper nochmals beeinträchtigt. Ferner bewirken die auf den nachgiebigen Gummikörpern nicht immer genau konzentrisch sitzenden Blechringe usw. durch Fliehkraftwirkung eine schädliche Unwucht bzw. ein Schlagen der Kupplung,. was durch die Elastizität des Gummis noch gesteigert wird. Eis sind :auch andere elastische Kupplungen mit als Kugel oder Doppelkegel ,ausgebildeten Gummikörpern :an .Metallhülsen bekannt, die jedoch nicht als Ganzes zwischen den Kupplungsscheiben durch Zusammendrücken eingeführt werden können, keine aufvulkanisierten Zentrierringe aufweisen und nur eine sehr begrenzte Elastizität, Biegsamkeit und Wellenverlagerung der Kupplung gewähren.Elastic shaft coupling with between the coupling disks as a whole Rubber body that can be inserted when compressed. They are elastic shaft couplings with between the clutch disks: insertable as a whole when compressed Rubber body known. This consists partly of one; or two screwable Rubber bodies that are conical in the middle and flat on the inner and outer edges Have cross-section. Metal rings are clamped or on the inner and outer edge vulcanized on, which is centered on the shaft flanges and with these by screws are connected. Because the clamping wheels are rigid and about half of the rubber body cross-section claim, only about half of the remains as an effective, resilient part Rubber body. However, this changes the elasticity and flexibility of the coupling greatly reduced that the insertion of the rubber body between the shaft flanges a special device is required. With the couplings with two conical Rubber bodies are the latter in the middle: encased by sheet metal rings and washers and connected by screws or rivets. Due to the rigid sheet metal rings etc. are however, the elasticity and flexibility of the rubber body is impaired again. Furthermore, the effect on the flexible rubber bodies is not always exactly concentric seated sheet metal rings etc. cause a damaging imbalance or a harmful imbalance due to the effect of centrifugal force Hitting the clutch ,. which is increased by the elasticity of the rubber. Ice are: also other elastic couplings with spheres or double cones Rubber bodies: known from metal sleeves, but they are not as a whole can be inserted between the clutch plates by pressing them together, none have vulcanized centering rings and only a very limited elasticity, Allow flexibility and shaft displacement of the coupling.

Die Erfindung löst die Aufgabe, die den bekannten Wellenkupplungen anhaftenden Mängel in der Weise zu beseitigen, daß der zwischen den Einspannrändern befindliche nachgiebige Teil des membranförmigen Gummikörpers durch Neugestaltung seiner Einspannung eine erhebliche Erhöhung an Elastizität und Biegsamkeiterfährt, damit, sowohl das Einfügen oder Auswechseln des Gummikörpers völlig ohne Vorrichtung möglich ist, als auch die Kupplung durch ihr nachgiebiges, nicht eingespanntes Gummivolumen größere Winkel-und Höhenverlagerungen und größte durch Stoßbelastungen verursachte Verdrehungswinkel der gekuppelten Wellen zuläßt. Zur Lösung dieser Aufgabe ist der Gummikörper an seinem kleinen Zentrierflansch, wie bereits vorgeschlagen, radial aufvulkanisiert, gemäß der Erfindung jedoch an seinem großen Zentrierflansch, in einer Hohlkehle auslaufend, achsparallel aufvulkanisiert. Dadurch werden die Befestigungshöhe am großen Zentrierflansch zugunsten des elastischen Gummivolumens auf ein Minimum verringert und somit als fortschrittliche Wirkung ein Maximum an Elastizität und Biegsamkeit erreicht. Da der achsparallel und in einer Hohlkehle auslaufende Gummikörper durch sein größeres, nicht eingespanntes elastisches Volumen auch in axialer Richtung hochelastisch ist, läßt sich als weiterer Fortschritt das Einfügen und Auswechseln desselben zwischen den Kupplungsscheiben ganz ohne Vorrichtung ausführen. Als weitere Verbesserung sind zur Erhöhung der Gummikörperlebensdauer am großen Kupplungsflansch innen Lufteintritts- und außen Luftaustrittslöcher vorgesehen. Durch Fliehkraftwirkung wird hierbei eine Durchlüftung und Kühlung des Gummikörpers auf einfachste Weise herbeigeführt.The invention solves the problem that the known shaft couplings to eliminate adherent defects in such a way that the between the clamping edges located resilient part of the membrane-shaped rubber body by redesigning its restraint experiences a considerable increase in elasticity and flexibility, thus, both inserting and replacing the rubber body completely without a device is possible, as is the coupling due to its flexible, non-clamped rubber volume major shifts in angle and height and largest caused by shock loads Rotation angle of the coupled shafts allows. To solve this problem is the Rubber body on its small centering flange, as already proposed, radially vulcanized, according to the invention, however, on its large centering flange, in tapering to a groove, vulcanized parallel to the axis. This will increase the mounting height on the large centering flange in favor of the elastic rubber volume to a minimum reduced and thus as a progressive effect a maximum of elasticity and Flexibility achieved. Because the rubber body running parallel to the axis and in a groove due to its larger, unconstrained elastic volume also in the axial direction is highly elastic, can be inserted and replaced as a further advance do the same between the clutch disks without any device. As another Improvements are to increase the rubber body life on the large coupling flange Air inlet holes on the inside and air outlet holes on the outside. Through the effect of centrifugal force This is a ventilation and cooling of the rubber body in the simplest way brought about.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung im Längsschnitt. Der Gummikörper a ist zwischen einem großen Nabenflansch b und einem kleinen Nabenflansch c angeordnet. Er ist nach der Zeichnung in einer Hohlkehle auslaufend am großen Zentrierflansch d achsparallel und am kleinen Zentlrierflansch e radial aufvulkanisiert. Der Zentrierflansch d ist am Nabenflansch b zentriert und durch Schrauben f mit ihm verbunden. Der Zentrierflansch e ist am Nabenflansch c zentriert und mit ihm durch Schrauben g verbunden. Zum Lösen der Kupplung werden die Schrauben f, g entfernt und der Gummikörper a so weit zusammengedrückt, daß die Zentrierauflagen frei werden und der Gummikörper zwischen den Nabenflanschen b, c herausgezogen werden kann. Der Einbau des Gummikörpers erfolgt in umgekehrter Reihenfolge. Im großen Nabenflansch b sind Lufteintrittslöcher h und Luftaustrittslöcher i angebracht, damit dauernd Frischluft durch die Löcher h einströmt, den Gummikörper a kühlt und die durch die Walkarbeit des Gummis erzeugte heiße Luft aus den Löchern i ausströmt.The drawing illustrates an embodiment of the invention in longitudinal section. The rubber body a is between a large hub flange b and a small hub flange c arranged. According to the drawing, it is in a hollow ending at the large centering flange d axially parallel and at the small centering flange e vulcanized radially. The centering flange d is centered on the hub flange b and connected to it by screws f. The centering flange e is on the hub flange c centered and connected to it by screws g. To release the clutch will be the screws f, g removed and the rubber body a compressed so far that the centering pads become free and the rubber body between the hub flanges b, c can be pulled out. The installation of the rubber body is done in reverse Series. In the large hub flange b there are air inlet holes h and air outlet holes i attached so that fresh air constantly flows in through the holes h, the rubber body a cools and the hot air generated by the flexing of the rubber from the holes i emanates.
