Description

Verbindung von Maschinenteilen mittels Spannelementen Die Neuerung betrifft Maschinenteile, die mittels Spannelementen verbunden werden, wobei die Spannelemente aus einem oder mehreren kegeligen Innen-und Außenringen bestehen. Connection of machine parts using clamping elements The innovation relates to machine parts that are connected by means of clamping elements, whereby the Clamping elements consist of one or more conical inner and outer rings.

Derartige Spannelemente werden als kraftschlüssige, spielfreie Verbindungsglieder zwischen Welle und Bohrung bei Maschinenteilen eingesetzt.Such clamping elements are used as non-positive, backlash-free connecting links used between shaft and bore in machine parts.

Versuche haben gezeigt, daß diese Elemente infolge ihres Reibungsschlusses Drehmomente übertragen können, die zahlenmäßig weit höher liegen als jene Werte, die bisher mit Hilfe der üblichen Verbindungselemente wie Federn, Keile usw. erreicht wurden.Tests have shown that these elements as a result of their frictional engagement Can transmit torques that are numerically far higher than those values which so far achieved with the help of the usual connecting elements such as springs, wedges, etc. became.

Für gewöhnlich liegen die Anwendungsmöglichkeiten und der Einsatz dieser Spannelemente auf dem Gebiete der Maschinenteileverbindung, der Mitnehmerverbindung für Zahnräder, Schwungräder, Keilriemen- scheiben o. ä., also Verbindungen, für die die Größe des zu über- tragenden Drehmomentes annähernd konstant bleibt und Weohselbeanspruohungen allgemein nicht auftreten.Usually the application possibilities and the use of these clamping elements are in the area of the machine part connection, the driver connection for gear wheels, flywheels, V-belt disks or similar, i.e. connections for which the size of the bearing torque remains approximately constant and stresses and strains generally do not occur.

Werden nun aber diese Spannelemente auch für die Übertragung von Drehmomenten eingesetzt, die keine konstanten Werte zeigen, sondern bei-denen die Kräfte Werte annehmen-wenn auch zeitlich nur für kurze Augenblicke-, die ein Vielfachen der normalen Beanspruohungswerte betragen, so ergeben sich derart dhohe Beanspr@chungen für das Material, daß das Material entweder diesen Beanspruchungen nicht Stand hält und bricht oder aber es tritt infolge kurzer Gleitbewegungen ein regelrechtes Verschweißen dieser Spannelemente mit dem Material ein.But now these clamping elements are also used for the transmission of torques are used, which show no constant values, but for which the forces are values accept - even if only for brief moments - that are a multiple of the normal Are high stress values for the Material that the material either does not withstand these stresses and breaks or a proper welding occurs as a result of short sliding movements these clamping elements with the material.

Um diesen Nachteilen zu begegnen, sieht die Neuerung eine Lösung vor, die darin besteht, daß für derartige Verbindungen die mit den Außendurchmessern der Spannelemente in Berührung kommenden Maschinenteile an der Berührungsfläche mit einer Schicht versehen sind, die Notlaufeigenschaften aufweist.To counter these disadvantages, the innovation provides a solution, which consists in the fact that for such connections those with the outer diameters machine parts coming into contact with the clamping elements at the contact surface are provided with a layer that has emergency running properties.

Anstelle dieser aufzubringenden Schicht kann auch eine Büchse eingezogen werden, die gleichfalls Notlaufeigenschaften besitzt, so daß auf der einen Seite keine direkte Berührung zwischen den Spannelementen und dem Maschinenteil gegeben ist. Die Büchse ist andererseits in der Wandung so dimensioniert oder durch konstruktive Maßnahmen nachgiebig gemacht, daß die Reibungspaarung Welle-Nabe nicht gestört wird.Instead of this layer to be applied, a sleeve can also be drawn in are, which also has emergency running properties, so that on the one hand there is no direct contact between the clamping elements and the machine part is. The sleeve is on the other hand dimensioned in the wall or by constructive Measures made resilient that the friction pairing shaft-hub is not disturbed.

In der Abbildung ist ein Ausführungsbeispiel dieser Neuerung wiedergegeben, und zwar ist zwischen die Spannelemente 1 und ein Maschinenteil 2 eine Büchse 3 eingezogen, so daß kein unmittelbarer Reibungsschluß zwischen den Spannelementen 1 und dem Maschinenteil 2 gegeben ist. SchutzansprücheThe figure shows an embodiment of this innovation, namely, a bush 3 is between the clamping elements 1 and a machine part 2 drawn in, so that no direct frictional engagement between the clamping elements 1 and the machine part 2 is given.
