Abstract

The present invention relates to a camshaft, more particularly for a door closer, the cam of which is produced separately from the shaft body and subsequently connected permanently and durably to the shaft body. In order to simplify the production of such a camshaft, more particularly for a door closer, the invention provides that the connection is made by means of a form-fit, wherein said form-fit is formed in such a manner that a distinctive, aligned positioning of the cam (4), secured to prevent axial displacement of the cam (4) and shaft body (1), is guaranteed at the shaft body (4).

Description

Titel: Nockenwelle, insbesondere für einen Türschließer  Title: Camshaft, especially for a door closer
Beschreibung  description
Die vorliegende Erfindung betrifft eine Nockenwelle, insbesondere für einen Türschließer, deren Nocken getrennt vom Wellenkörper gefertigt und durch späteres Fügen dauerfest mit dem Wellenkörper verbunden ist. The present invention relates to a camshaft, in particular for a door closer, whose cam is made separately from the shaft body and permanently connected by subsequent joining with the shaft body.
Bisher war es üblich, den Nocken mit dem gedrehten und geschliffenen Wellenkörper zu verschweißen. Dies ist sehr aufwändig, da der Nocken zunächst in einem ersten Arbeitsgang zum Wellenkörper ausgerichtet und dann in einem zweiten Arbeitsgang mit diesem verschweißt werden muss. So far, it was customary to weld the cam with the turned and ground shaft body. This is very complicated, since the cam must first be aligned in a first operation to the shaft body and then welded in a second operation with this.
Es ist daher Aufgabe der vorliegenden Erfindung, die Herstellung einer Nockenwelle, insbesondere für einen Türschließer, zu vereinfachen. It is therefore an object of the present invention to simplify the production of a camshaft, in particular for a door closer.
Diese Aufgabe wird bei einer Nockenwelle, insbesondere für einen Türschließer, deren Nocken getrennt vom Wellenkörper gefertigt und durch späteres Fügen .dauerfest mit dem Wellenkörper verbunden ist, erfindungsgemäß dadurch gelöst, dass die Verbindung mittels eines Formschlusses erfolgt, wobei der Formschluss derart ausgebildet ist, dass er eine unverwechselbare, ausgerichtete und gegen eine Axialverschiebung von Nocken und Wellenkörper gesicherte Positionierung des Nocken an dem Wellenkörper gewährleistet. This object is achieved with a camshaft, in particular for a door closer whose cam is separate from the shaft body and fatigue connected by later joining with the shaft body, according to the invention, that the connection is effected by means of a positive connection, wherein the positive connection is formed such that he ensured a distinctive, aligned and secured against axial displacement of the cam and shaft body positioning of the cam on the shaft body.
BESTÄTIGUNGSKOPIE Infolge dieser Ausgestaltung gibt es nur eine Möglichkeit, wie der Nocken auf den Wellenkörper aufgesteckt werden kann, so dass es nicht zu Verwechslungen bzw. Falschausrichtungen kommen kann. Darüber hinaus ist die formschlüssige Verbindung so aus- gestaltet, dass ein Herauswandem des Wellenkörpers aus dem Nocken verhindert wird. Weiterhin entfällt der Schweilivorgang. CONFIRMATION COPY As a result of this configuration, there is only one way in which the cam can be plugged onto the shaft body, so that it can not lead to confusion or misalignment. In addition, the positive connection is designed so that a wall of the shaft body from the cam is prevented. Furthermore, eliminates the Schweilivorgang.
Die Unteransprüche haben vorteilhafte Weiterbildungen der Erfindung zum Inhalt. The dependent claims have advantageous developments of the invention to the content.
Gemäß einer vorteilhaften Ausgestaltung ist der Nocken mit einem Achsstummel versehen, welcher in eine korrespondierende Ausnehmung in dem Wellenkörper eingreift. Dies stellt eine besonders einfache Möglichkeit dar, Nocken und Wellenkörper miteinander zu verbinden. According to an advantageous embodiment of the cam is provided with a stub axle, which engages in a corresponding recess in the shaft body. This is a particularly easy way to connect cam and shaft body together.
Die Ausnehmung bzw. der Achsstummel weist vorteilhafterweise eine Querschnittsform auf, welche sich ergibt, wenn man an die Basis eines Halbkreises ein gleichschenkeliges Trapez anfügt. The recess or the stub axle advantageously has a cross-sectional shape which results when an isosceles trapeze is added to the base of a semicircle.
Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung anhand der Zeichnungen. Es zeigen: Figur 1 einen Querschnitt durch den Wellenkörper, Further details, features and advantages of the invention will become apparent from the following description with reference to the drawings. 1 shows a cross section through the shaft body,
Figur 2 eine Draufsicht auf den Wellenkörper, FIG. 2 shows a plan view of the shaft body,
Figur 3 eine Draufsicht auf den Nocken, und Figur 4 die Querschnittsform der im Wellenkörper vorhandenen Ausnehmung. Figure 3 is a plan view of the cam, and FIG. 4 shows the cross-sectional shape of the recess present in the shaft body.
In Figur 1 ist ein Wellenkörper 1 im Querschnitt gezeigt, der insbe- sondere bei einem Türschließer Verwendung findet. In dem Wellenkörper 1 ist eine Ausnehmung 2 vorgesehen, welche zur Aufnahme eines Achsstummels 3 eines Nockens 4 dient. In Figure 1, a shaft body 1 is shown in cross section, which is used in particular in a door closer use. In the shaft body 1, a recess 2 is provided which serves to receive a stub axle 3 of a cam 4.
Der Achsstummel 3, der einseitig von dem Nocken 4 vorsteht, und die Ausnehmung 2 in dem Wellenkörper 1 haben eine korrespondierende Form, so dass eine formschlüssige Verbindung zwischen den beiden Bauteilen eingegangen wird, die den Nocken 4 unverwechselbar, ausgerichtet und gegen eine Axialverschiebung von Nocken 4 und Wellenkörper 1 gesichert an dem Wellenkörper 1 positioniert. Dazu weist die Ausnehmung 2 bzw. der Achsstummel 3 eine Form auf, die man erhält, wenn man an die Basis eines Halbkreises ein gleichschenkeliges Trapez anschließt, wie es in Figur 4 gezeigt ist. Die erfindungsgemäße Verbindung ermöglicht eine eindeutige Ausrichtung von Nocken 4 und Wellenkörper 1 ohne Schweißen und kann insbesondere bei Boden- oder Rahmentürschließern eingesetzt werden. Die vorhergehende Beschreibung der vorliegenden Erfindung dient nur zu illustrativen Zwecken und nicht zum Zwecke der Beschränkung der Erfindung. Im Rahmen der Erfindung sind verschiedene Änderungen und Modifikationen möglich, ohne den Umfang der Erfindung sowie ihrer Äquivalente zu verlassen. Bezugszeichenliste The stub axle 3, which projects unilaterally from the cam 4, and the recess 2 in the shaft body 1 have a corresponding shape, so that a positive connection between the two components is received, the cam 4 unmistakably aligned and against an axial displacement of cams 4 and shaft body 1 secured to the shaft body 1 positioned. For this purpose, the recess 2 or the stub axle 3 has a shape which is obtained by connecting an isosceles trapezoid to the base of a semicircle, as shown in FIG. The connection according to the invention enables a clear alignment of cams 4 and shaft body 1 without welding and can be used in particular in floor or frame door closers. The foregoing description of the present invention is for illustrative purposes only, and not for the purpose of limiting the invention. Various changes and modifications are possible within the scope of the invention without departing from the scope of the invention and its equivalents. LIST OF REFERENCE NUMBERS
