Das auf diese Weise durch kontinuierliches Biegen ausgeformte Gabelteil weist keine Verfestigungsstellen auf.The fork part formed in this way by continuous bending has no solidification points.
Gemäß einer Weiterbildung der Erfindung erfolgt das Biegen vorzugsweise durch Kaltverformung.According to a further development of the invention, the bending takes place preferably by cold forming.
Ein Endbereich des der Welle zugeordneten Teiles wird gemäß einer anderen Weiterbildung der Erfindung so geformt, daß er der konvexen kontinuierlichen Krümmung des mittleren Bereiches des eigentlichen Gabelteiles angepaßt ist, an welchen es angeschweißt werden soll.According to another development of the invention, an end region of the part assigned to the shaft is shaped in such a way that it the convex continuous curvature of the central region of the actual fork part is adapted to which it is to be welded.
Die Erfindung betrifft außerdem eine Gabel für Gelenkkupplungen von Kraftübertragungen, die beispielsweise in landwirtschaftlichen oder ähnlichen Geräten oder dergleichen Verwendung finden. Diese ist erfindungsgemäß dadurch gekennzeichnet, daß sie aus einem eigentlichen Gabelteil aus einem mit kontinuierlicher Krümmung gebogenen Profilstück und einem der Welle zugeordneten Teil besteht, dessen einer Endbereich eine für die Verbindung und das Anschweißen an den zentralen Bereich des genannten Gabelteiles geeignete Formgebung aufweist.The invention also relates to a fork for articulated couplings of power transmissions which are used, for example, in agricultural or similar devices or the like. According to the invention, this is characterized in that it consists of an actual fork part with a continuous curvature curved profile piece and a part associated with the shaft, one end region of which is a for the connection and welding to the central area of said fork part has a suitable shape.
Die Erfindung betrifft außerdem eine Gabel, die nach dem oben beschriebenen Verfahren hergestellt ist und die infolgedessen aus einem Profilstück besteht, das durch Kaltverformung mit kontinuierlicher Krümmung gebogen ist und daher keine Verhärtung s- oder Verfestigungsstellen aufweist sowie aus einem der Welle zugeordneten Teil oder Kernstück zur Ankupplung der Welle, das in dem mittleren Bereich des durch Kaltverformung gebogenen Gabelteiles angeschweißt ist. Das charakteristische Merkmal dieser Gabel besteht in dem im wesentlichen kontinuierlichen und dabei einen großen Halbmesser aufweisenden Kurvenstück, das die eigentliche Gabel bildet und durch die beschriebene Bearbeitungsart erhalten wird und den wesentlichen Vorteil aufweist, daß Verfestigungen und damit Fehler des fertigen Teiles vermieden sind.The invention also relates to a fork which is manufactured according to the method described above and which as a result consists of a profile piece, which by cold forming with continuous curvature is bent and therefore has no hardening s or solidification points and from one of the Shaft associated part or core piece for coupling the shaft, which is welded in the middle area of the fork part bent by cold forming. The characteristic The feature of this fork consists in the essentially continuous curve piece with a large radius, which forms the actual fork and is obtained by the type of machining described and has the essential advantage that solidifications and thus errors in the finished part are avoided.

Im ί öl /τ end en fioi die Erfindung anhand der Zeichnungen näher erläutert:In the ί oil / τ end en fioi the invention with reference to the drawings explained:
Fig. 1, 2 und 3 zeigen das Stück, welches das eigentliche Gabelteil bildet in drei verschiedenen Ansichten, wobei in Fig. 1 in strichpunktierten Linien die Gestalt des Profilstückes angedeutet ist, die dieses vor seiner Krümmung durcli Kaltverformung besitzt,Fig. 1, 2 and 3 show the piece, which the actual Fork part forms in three different views, with the shape in dot-dash lines in FIG. 1 of the profile piece is indicated, which this has before its curvature by cold deformation,
Fig. k und 5 zeigen die vollständige Gabel bzw. die beiden Bestandteile vor dem Zusammenschweißen.FIGS. K and 5 show the complete fork or the two components before being welded together.
Wie aus Fig. 1 bis 3 ersichtlich wird, geht man bei der Ausbildung des gabelförmigen Teiles von einem geradlinigen Profilstück aus, das in seiner Gesamtheit (in Fig. 1) mit 1X bezeichnet ist. Dieses Profilstück wird, gegebenenfalls nach einer vorbereitenden Formgebung, mit einer kontinuierlichen oder zumindest im wesentlichen kontinuierlichen Krümmung mit dem Halbmesser R (Fig. 1) derart gebogen, daß es zwei Arme 1 sowie einen kurvenförmigen Verbindungsteil 1A mit ansteigender und mehr oder weniger kontinuierlicher Krümmung bildet. Diese Krümmung wird im wesentlichen durch Abbiegen mittels Kaltverformung erzielt. Die Behandlung und insbesondere der Vorgang des Abbiegens sind so gewählt, daß Verfestigungen des Materials vermieden sind, so daß die ihm ursprünglich eigene Widerstandsfähigkeit erhalten bleibt.As can be seen from Fig. 1 to 3, one goes in the training of the fork-shaped part of a straight profile piece, which in its entirety (in Fig. 1) with 1X is designated. This profile piece is, if necessary after a preparatory shaping, with a continuous or at least substantially continuous curvature with the radius R (Fig. 1) bent in such a way that there are two arms 1 and forms a curved connecting part 1A with an increasing and more or less continuous curvature. This curvature is essentially achieved by bending by means of cold deformation. The treatment and especially the The process of turning are chosen so that solidifications of the material are avoided, so that it retains its original resistance.
Nach der Herstellung des Gabelteiles 1, 1A wird die Gabel dadurch vervollständigt, daß ein Wellen- bzw. Nabenteil 5 in einer in Bezug auf das Gabel teil symmetrischen Position angefügt und durch eine Schweißnaht 7 an dem zentralen gebogenen Bereich 1A des Gabelteiles 1, 1A angeschweißt wird. In Anpassung an die kontinuierliche Krümmung des Bereiches 1A ist der Endbereich 5A des Wellen- oder Nabenteiles 5 so ausgeformt, daß es der konvexen kontinuierlichen Krümmung des Bereiches 1A entspricht.After the manufacture of the fork part 1, 1A, the fork is completed in that a shaft or hub part 5 in a partially symmetrical position with respect to the fork attached and bent by a weld 7 at the central one Area 1A of the fork part 1, 1A is welded. In adaptation to the continuous curvature of the area 1A the end area 5A of the shaft or hub part 5 is shaped so that it is the convex continuous curvature of the Area 1A corresponds.
Di e auf diese Weise hergestellte Gabel besitzt vorteilhafte Eigenschaften beim Gebrauch und bietet darüber hinaus dieThe fork produced in this way has advantageous Properties in use and also offers the
