Description
Zapfwellen-Kupplung, insbesondere für Landmaschinen Zapfwellen für Landmnschinem zur Übertragung der Antriebsleistung von einer Zugmaschine auf eine Arbeitsmaschine oder einen Anhänger mit Antriebsachse sollen leicht und schnell ohne Werkzeug auch von ungeschultem Personal zu kuppeln sein. Die Verbindung muß daibei besonders gegen Axialkräfte widerstandsfähig sein. Die bekannten: Kupplungsvorrichtungen befriedigen in dieser Hinsicht nicht und sind zum Teil in ihrer Konstruktion umständlich und teuer in der Herstellung.PTO shaft clutch, especially for agricultural machinery PTO shafts for Agricultural machinery for the transmission of drive power from a tractor to a Work machine or a trailer with a drive axle should be quick and easy can be coupled by untrained personnel without tools. The connection must be particularly resistant to axial forces. The well-known: coupling devices are unsatisfactory in this regard and are sometimes cumbersome in their construction and expensive to manufacture.
Gemäß der Erfindung wird eine Zapfwellen-Kupplung vorgeschlagen, welche bei einfachster Bauart ein ganz leichtes Kuppeln ohne Zuhilfenahme von Werkzeugen ermöglicht und eine auch gegenüber den größtmöglichen Axialkräften widerstandsfähige Verbindung herstellt. Sie ist im wesentlichen gekennzeichnet durch die Verwendung eines innen mit Erhebungen versehenen Drehkörpers als Sperrmittel des auf die Zapfwelle aufgeschobenen rohrförmigen Gelenkteiles gegen Axialkräfte. Der Drehkörper ist vorzugsweise als Ring ausgebildet, der innen das gleiche oder ähnliche Keilnutprofil hat wie der auf die Zapfwelle aufzuschiebende rohrförmige Gelenkteil und ein diesem in axialer Richtung .gesperrt, jedoch begrenzt drehbar gelagert ist. Eine Feder dreht den Ring so weit, daß seine inneren Erhebungen in die Ringrille auf dem Keilnutprofil der Zapfwelle eingreifen, sobald der rohrförmige Gelenilotei,l genügend weit auf :die Zapfwellle aufgeschoben :ist. Die Drehbewegung des Sperrringes wird durch einen oder mehrere Mitnehmerstifte begrenzt, welche sich in je einem Querschlitz des rohrförmigen Gelenkteiles verschieben können.According to the invention, a power take-off clutch is proposed which with the simplest design, very easy coupling without the aid of tools and one that is also resistant to the greatest possible axial forces Establishes connection. It is essentially characterized by the use a rotating body provided with elevations on the inside as a locking means of the on the PTO shaft pushed-on tubular joint part against axial forces. The rotating body is preferably designed as a ring that has the same or similar keyway profile as the inside the tubular joint part to be pushed onto the PTO shaft and an axial joint part thereof Direction .blocked, but is supported rotatably to a limited extent. A spring turns the ring so far that its inner elevations in the annular groove on the keyway of the PTO engage as soon as the tubular gelenilotei, l is sufficiently far on: the PTO open: is. The rotation of the locking ring will limited by one or more driver pins, which are each located in a transverse slot of the tubular joint part can move.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. In Fig. I ist ein rohrförmiger Gelenkteil I zum Teil im Schnitt dargestellt; Fig.2 veranschaulicht denselben in Draufsicht, Fig. 3 den Zäpfwellenstummel üblicher Bauart I I mit genormtem Keilnutprofil und Ringrille Io; Fig. 4 zeigt einen senkrechten Schnitt zu Fig. I und 2.The drawing shows an embodiment of the invention. In Fig. I a tubular joint part I is shown partly in section; Fig.2 illustrates the same in plan view, Fig. 3 the spotting shaft stub of the usual type I I with standardized Keyway and ring groove Io; FIG. 4 shows a perpendicular section to FIG and 2.
Der ringförmige Sperrkranz 2 ist in der erweiterten Bohrung 7 des Gelenkteiles I drehbar gelagert, wobei seine Drehung durch den Mitnehmerstift 3 in Versbindung mit dem Querschlitz 6 begrenzt wird. Eine Buchse 5 stützt in Verbindung mit einem Spannring I2 den Sperring 2 gegen den Gelenkteil I in axialer Richtung ab. Eine gewundene Biegungsfeder 4 ist mit einem ihrer rechtwinklig abgebogenen Enden in einer Bohrung 13 der Buchse 5 und mit dem anderen in einer Bohrung 14 des Sperringes 2 abgestützt, wo sie zugleich einen mit Querbohrung versehenen Mitnehmerstift 3 in einer Radialbohrung des Sperringes 2 festhält, der die Drehbewegung des Sperringes 2 indem, Schlitz 6 begrenzt. Ein außen auf dem rohrförmigen Gelenkteil I drehbar gelagerter Drehring 9 wird durch einen oder mehrere Mitnehmerstifte 3 mit dem Sperring verbunden. Das Kuppeln und Entkuppeln ist durch diesen Außenring 9 sehr erleichtert, durch welchen auch eine glatte Außenfläche des umlaufenden Gelenkteiles I erzielt wird, was zur Verhütung von Unfällen sehr wesentlich ist. Die Buchse 5 kann auch durch mehrere Spannstifte mit dem Gelenkteil I verbunden sein. Es ist vorteilhaft; den Sperrring 2 innen mit einem Keilnutprofil zu versehen, das zu dem Außenprofil auf dem Zapfwellenstumpf I I paßt, und die Erhebungen entsprechend der Ringrille Io abzurunden. Dann wird eine gute Axialiabstützung des Gelenkteiles I auf der Zapfwelle I I mit geringem Spiel erreicht, was für den einwandfreien und ruhigen Lauf der Zapfwellen sehr wesentlich ist.The annular locking ring 2 is in the enlarged bore 7 of the The joint part I is rotatably mounted, its rotation being controlled by the driver pin 3 is limited in connection with the transverse slot 6. A socket 5 supports in connection with a clamping ring I2 the locking ring 2 against the joint part I in the axial direction away. A coiled bending spring 4 is bent at right angles with one of its Ends in a bore 13 of the socket 5 and with the other in a bore 14 of the Locking ring 2 supported, where they also have a cross-drilled driving pin 3 holds in a radial bore of the locking ring 2, the rotational movement of the locking ring 2 by, slot 6 limited. One on the outside of the tubular joint part I rotatable mounted rotating ring 9 is by one or more driving pins 3 with the locking ring tied together. Coupling and uncoupling is made much easier by this outer ring 9, through which a smooth outer surface of the circumferential joint part I is achieved becomes, which is very essential for the prevention of accidents. The socket 5 can also be connected to the joint part I by several dowel pins. It's beneficial; to provide the locking ring 2 with a keyway profile on the inside, which corresponds to the outer profile on the PTO stub I I fits, and the elevations correspond to the annular groove Round off Io. Then there is good axial support of the joint part I on the power take-off shaft I I achieved with little play, which is essential for the smooth and smooth running of the PTO is very essential.
