Abstract

The positive detachable connection, typically between a shaft and a hub, comprises an eccentric boss (11) formed on the end face of one component (10). In the other component (12) are two mating recesses (13,14), in which the end portion of the first one complete with boss engages. The first component can be cylindrical, as can the boss, while the recesses can comprises a stepped bore with offset portions. The components can be held together by a screw (15). The design gives a positive coupling and is simple and cheap to mfr.

Description

Lösbare VerbindungDetachable connection

Stand der Technik Die Erfindung betrifft eine lösbare Verbindung einer Welle mit einer Nabe. Bekannte Verbindungen dieser Art benutzen Paßfedern, Keile oder Stifte, üblich sind- auch-Profilwellen und Profilnaben, Polygonverbindungen, Klemniverbindungen oder Spannelemente. Diese Verbindungen be- -nötigen entweder einen großen Aufwand an Teilen oder beanspruchen viel Platz.PRIOR ART The invention relates to a releasable connection of a Shaft with a hub. Known connections of this type use parallel keys, wedges or pins, also common are profile shafts and profile hubs, polygon connections, Clamp connections or clamping elements. These connections require either a lot of parts or take up a lot of space.

Vorteile der Erfindung Die erfindungsgemäße lösbare Verbindung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß sie bei geringem Aufwand einen guten Kraftschluß zwischen den zu verbindenden Teilen herstellt. Sie ist außerdem äußerst platzsparend und kann auch kostengünstig gefertigt werden Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Merkmale möglich.Advantages of the invention The releasable connection according to the invention with the characterizing features of the main claim has the advantage that they create a good frictional connection between the parts to be connected with little effort manufactures. It is also extremely space-saving and can also be manufactured inexpensively The measures listed in the subclaims are advantageous Further developments and improvements to the features specified in the main claim are possible.

Zeichnung Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen Figur 1 einen Längsschnitt durch eine lösbare Verbindung, Figur 2 eine Ansicht dieser Verbindung.Drawing An embodiment of the invention is shown in the drawing and explained in more detail in the following description. It show figure 1 shows a longitudinal section through a releasable connection, FIG. 2 shows a view of this Link.

Beschreibung des Ausführungsbeispieles In Figur 1 ist mit 10 eine Welle bezeichnet, die an ihrer Stirnseite einen exzentrischen Ansatz 11 aufweist, der zylindrisch ausgebildet ist und verhältnismäßig kurz ist.Description of the exemplary embodiment In FIG. 1, 10 is a Shaft referred to, which has an eccentric projection 11 on its end face, which is cylindrical and relatively short.

Die Stirnseite der Welle taucht in entsprechende passende Ausnehmungen einer Nabe 12. Diese passende Ausnehmung besteht aus einer Bohrung 13, welche dem Wellendurchmesser entspricht und eine sich unmittelbar anschließende exzentrische Sackbohrung 14, die dem Durchmesser des Ansatzes 11 entspricht. Zur axialen Sicherung der beiden Teile ist.The end face of the shaft dips into corresponding matching recesses a hub 12. This matching recess consists of a bore 13, which the Corresponds to the shaft diameter and an immediately adjoining eccentric Blind hole 14, which corresponds to the diameter of the projection 11. For axial securing of the two parts is.

eine Schraube 15 vorgesehen, welche in die Stirnseite der Welle 10 eingeschraubt ist und die Nabe 12 an die Welle preßt.a screw 15 is provided which is inserted into the end face of the shaft 10 is screwed in and the hub 12 presses against the shaft.

Selbstverständlich braucht es sich beim Gegenstand der Erfindung nicht um eine Welle und eine Nabe zu handeln, sondern auch um andere Teile, welche formschlüssig miteinander verbunden sein sollen, um insbesondere ein Drehmoment zu übertragen. Dies wird dadurch erreicht, daß beim Drehen der Welle 10 der Ansatz 11 ein Drehmoment auf die Nabe 12 überträgt. Wenn die Teile beispielsweise durch Einpressen fest miteinander verbunden sind, kann auch die Schraube 15 entfallen.It goes without saying that there is no need for the subject matter of the invention to act as a shaft and a hub, but also to other parts which are form-fitting should be connected to each other, in particular to transmit a torque. This is achieved in that when the shaft 10 is rotated, the projection 11 generates a torque transfers to the hub 12. When the parts are firmly pressed together, for example are connected, the screw 15 can also be omitted.
