Description

Sicherheitswellenkupplung mit Bruchsicherung Die Erfindung betrifft eine Sicherheitswellenkupplung mit Bruchsicherung an einer Sollbruchstelle an einem Zwischenstück.Safety shaft coupling with break protection The invention relates to a safety shaft coupling with break protection at a predetermined breaking point on one Intermediate piece.

Es sind bereits Wellenkupplungen bekannt, bei denen die Sollbruchstelle von Brechbolzen gebildet wird, d. h. von Bolzen, die mit einer Einschnürung versehen sind und an dieser Stelle einen Querschnitt besitzen, der nach dem verlangten Sicherheitsdrehmoment bemessen ist.Shaft couplings are already known in which the predetermined breaking point is formed by shear pins, d. H. of bolts that are provided with a constriction and at this point have a cross-section that is dimensioned according to the required safety torque.

Es wird als Nachteil bekannter Brechbolzensicherungen angesehen, daß der eingeschnürte Querschnitt enge Sicherheitstoleranzen nicht zuläßt, da erfahrungsgemäß die Werkstoffestigkeit trotz aller Vorbehandlung streut und nicht vorbestimmbare, auf den Bolzen einwirkende Biegespannungen eine richtige Bemessung desselben erschweren. Außerdem besteht bei Brechbolzenkupplungen die Gefahr, daß die Bohrungen, in denen die Brechbolzen gehalten sind, im Fall eines Bruches beschädigt werden; das kann dazu führen, daß die beschädigten Teile nicht wieder verwendet werden können.It is regarded as a disadvantage of known shear bolt safety devices that the constricted cross-section does not allow tight safety tolerances, as experience has shown the material strength is scattered despite all pretreatment and cannot be predetermined, Bending stresses acting on the bolt make correct dimensioning of the same difficult. In addition, there is a risk of shear pin couplings that the holes in which the shear pins are held, damaged in the event of breakage; that can result in the damaged parts not being able to be used again.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu beseitigen.The invention is based on the object of eliminating these disadvantages.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Zwischenstück der Kupplung aus zwei miteinander verklebten Teilen besteht, wobei die verklebte Teilfuge als Sollbruchstelle vorgesehen ist.This object is achieved according to the invention in that the intermediate piece the coupling consists of two parts glued together, the glued Parting joint is provided as a predetermined breaking point.

Nach einem Bruch der geklebten Sollbruchstelle, die stets eine geringere Scherfestigkeit hat als die übrigen kraftübertragenden Teile der Kupplung, werden die Zwischenstückhälften gegen ein neues Zwischenstück ausgetauscht bzw. aufs neue miteinander verklebt und wiederverwendet, da die abgerissenen Klebflächen durch einfaches Abschleifen der Klebstoffreste wieder brauchbar gemacht werden können.After a break in the glued predetermined breaking point, this is always a smaller one Has shear strength than the rest of the force-transmitting parts of the coupling the intermediate piece halves exchanged for a new intermediate piece or anew glued together and reused because the torn adhesive surfaces through simply sanding off the adhesive residue can be made usable again.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung in einer Abbildung ün Schnitt dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing in a Figure shown in section and is described in more detail below.

Die Abbildung zeigt eine Zahnkupplung mit völlig symmetrischem Aufbau. Auf den zu kuppelnden Wellenenden (nicht dargestellt) sind die Kupplungshälften drehfest angebracht. Sie bestehen aus je einer fest mit der Welle verbundenen Kupplungsnabe 1 bzw. I' und aus einem die Nabe übergreifenden und mit ihr drehfest, aber gelenkig verbundenen Kupplungskranz 2 bzw. 2' mit Flansch 3 bzw. 3»*. Zwischen den Flanschen 3 und 3' ist ein Zwischenstück 4 angeordnet, das eine senkrecht zur Kupplungsachse liegende verklebte Teilfuge 5 aufweist. Zwischen den Flanschen 3 bzw. 3' beiderseits des Zwischenstückes 4 sind Stütz- und Abdeckscheiben 6 und 6" angeordnet.The illustration shows a tooth coupling with a completely symmetrical structure. The coupling halves are attached to the shaft ends to be coupled (not shown) in a rotationally fixed manner. They are composed of one each fixed to the clutch hub shaft 1 and I 'and non-rotatably from a hub cross, and with it, but articulated coupling ring 2 or 2' with flange 3 and 3 '*. Between the flanges 3 and 3 ' , an intermediate piece 4 is arranged, which has a glued parting line 5 lying perpendicular to the coupling axis. Support and cover disks 6 and 6 ″ are arranged between the flanges 3 and 3 'on both sides of the intermediate piece 4.
