Description
Die Erfindung betrifft eine Schutzvorrichtung für eine Kreuzgelenkanordnung, insbesondere für den Antrieb der Mischsehneckenwelle von Kegelschnekkenmisehern. mit einer teilkugelförmigen Schale, die sich zur Aufnahme von Axialkräfien an einer ortsfesten \ Errichtung abstützen kann, wobei das Kreuzgelenk mit seinem Wt.'cnstummel gegenüber der Abtriebswelle axial verschieblich ist.The invention relates to a protection device for a universal joint arrangement, in particular for driving the mixing screw shaft of cone screw mixers. with a partially spherical shell, which is used to absorb axial forces on a stationary \ Erection can support, whereby the universal joint with its Wt.'cnstummel opposite the output shaft is axially displaceable.
Bei einem bekannten Kcgekuineckenmischer (deutsche Au^lc-Vsehrift 1 262 <>77) sir I zwei ineinander rotierende Mischschnecken vorgesehen, von denen die äußere an der Kegelspitze mittels einer tcilkujeliOrmigen Pfanne an einer Kugelschale gelenkir· yelagrrt ist und die innere über ein im Inneren tier KiireKchale angeordnetes Kreuzgelenk angetrieben ist. Diese Anordnung ist deshalb nachteilig, weil das Kreuzgelenk die wiilirend des Mischvorganues auf die Mischschnecke ausgeübte axiale Belastung aufzunehmen hat und darüber hinaus die teilkugelforinige Pfanne das lindringen von Mischgut in das Kreuzgelenk nicht verhindert. Dadurch wird die I eK-nnlaucr des Kreuzgelenkes, insbesondere bei Mischern mit schweren Arbeilswerkzeugcn oder bei Vormischung von schwerem Gut. erheblich \erkurzt. In a known Kcgekuineckenmischer (German Au ^ lc-Vsehrift 1 262 <> 77) sir provided I two interlocking rotating mixing screws, the outer of which is at the apex by a tcilkujeliOrmigen pan on a spherical shell gelenki r · yelagrrt and the inner via a in Inner tier KiireKchale arranged universal joint is driven. This arrangement is disadvantageous because the universal joint has to absorb the axial load exerted on the mixing screw while the mixing device is in motion and, moreover, the partially spherical pan does not prevent the mix from penetrating into the universal joint. This increases the efficiency of the universal joint, especially in the case of mixers with heavy working tools or when premixing heavy goods. considerably shortened.
fs ist auch schon eine Schutzvorrichtung der eingang,
geschilderten Art bekannt geworden (USA-Patentschriften 1503 571 und 2 847 837). bei denen
eine von einem Kreuzgelenk rotierend angetriebene
Welle über eine axial verschieblichc Kciherzahnung mit d.T-,i Kreuzgelenk verbunden ist und zum Schulze
des Kreuzgelenkes vor Verschmutzung oder sonstigen ΐ influssen um dieses herum eine in einer Kugelpfanne
gelagerte Kugclschale einer. Kugelgelenkes angeordnet ist. Kinc derartige Schutzvorrichtung ist 1
doch zum Antrieb von Mischschnecken für Kegelschneckenmischer ungeeignet, weil die Antriebswelle
infolge ihrer Axialverschieblichkeit zur Aufnahme
von Axiaikräftcn nicht in der Lage ist.fs a protective device of the type described at the beginning has also become known (USA patents 1503 571 and 2 847 837). in which a shaft driven in rotation by a universal joint is connected to the universal joint via axially movable teeth and to protect the universal joint from dirt or other influences around it, a ball socket mounted in a ball socket. Ball joint is arranged. Kinc such protection device is 1
but unsuitable for driving mixing screws for cone screw mixers because the drive shaft is not able to absorb axial forces due to its axial displaceability.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Schutzvorrichtung der eingangs geschilderten An1 die eine tcilktigclfönnige Schale besitzt, so auszubilden, daß die Abfriebswclle, insbesondere die Mischschncckcnwel-Ie Volt KegclschrtCGkenmischcrn, keine Axialkräftc in dt\s Kreuzgelenk einleiten kann, Erfindiliigsgcmäß wird dies dadurch erzielt, daß der Wellenstiimmel des Kreuzgelenkes van einer Nabe der Abtriebswelle umschlossen ist, die eine ringförmige Aussparung aufweist, in der sich ejn ringförmiger Ansatz der Schale über ein Drucklager abstützt.Starting from this prior art, the invention is based on the object to form a protection device of the initially described at 1 having a tcilktigclfönnige shell so that the Abfriebswclle can initiate particular Mischschncckcnwel-Ie volts KegclschrtCGkenmischcrn, no Axialkräftc in dt \ s universal joint, According to the invention, this is achieved in that the shaft end of the universal joint is enclosed by a hub of the output shaft which has an annular recess in which an annular extension of the shell is supported via a thrust bearing.
Die erfindiingsgemäße Ausgestaltung der Schutzvorrichtung vereinigt somit in vorteilhafter Weise die Schutzfunktion der Kugelschale r.iii ?iner Halte- und Lagerfunktion dieser Kugelschaje in axialer Richtung. Das Kreuzgelenk wird durch die Kugelschale von schädlichen Einflüssen des Mischgutes und von Axialkräften der Mischschneckenwelle freigehalten. The design of the protective device according to the invention thus combines in an advantageous manner the protective function of the spherical shell r.iii? iner holding and Bearing function of this Kugelschaje in the axial direction. The universal joint is protected from harmful influences from the mix and from Axial forces of the mixing screw shaft kept free.
Die Erfindung wird nachfolgend an Hand eines bevorzugten Ausführungsbeispiels und der Zeichnungen beschrieben. Es zeigtThe invention is based on a Preferred embodiment and the drawings described. It shows

Die Kugelschale 5 fühlt in der Kugelpfanne 6 eine entsprechende, pendelnde Bewegung aus Die Kugelpfiinne liegt unterhalb des Bodens 7 des Behälters 2. Außerdem kann die Mischschnecke 1 durch Antriebsmittel S um ihre Achse gedreht werden Dieser Bewegung folgt die Kugelsehale 5 nicht, da sie über Gleitlager 9 (Fig. 2) auf der Achse der Mischschnecke gelagert ist.The mixing snail! migrates home to the operation of the Mixer in container 2 on an epicyclic path. This movement is provided by drive means 3 and 4 causes. The ball socket 5 senses a corresponding oscillating movement in the ball socket 6 The Kugelpfiinne is below the bottom 7 of the Container 2. In addition, the mixing screw 1 can be rotated about its axis by drive means S The ball socket 5 does not follow this movement, since it is on the axis of the sliding bearing 9 (FIG. 2) Mixing screw is mounted.

The rotation of the drive shaft is transmitted via the cross joint 11 to the drive shaft 12. 13. This consists of a stub shaft 12 connected to the universal joint 11 and a hollow shaft 13 carrying the mixing screw - movable. It is supported Vi axial pressure load via an axial deep groove ball bearing 14 and with tensile load via an axial Rilfenkujjellager 15 on a book c "nfü, shaped approach 5 'of the spherical shell 5. This carries t.ie sliding bearing 9th through which he in radial Fr is connected in the direction of the hollow shaft 13 by a sleeve 13 'fixed to the hollow shaft 13. The space between the sleeve and the attachment is advantageously closed off by sealing means 16 on the mixing room.
