Abstract

The coupling has a connecting piece (5) between the drive shaft and folding roller (10), which piece is arranged so as to be displaceable radially to the drive shaft axis in one coordinate but is rotationally fixed relative to the latter, and has a bearing lever (2) which can be secured to the folding-device frame (1) and having a passage bore (4) for the reception of a rolling bearing (11) seated on the folding or cutting roller, beyond which bearing a roller end section (13) of the folding or cutting roller for a rotary connection with the drive shaft projects and is connected in a rotationally fixed manner to the connecting piece (5) which is radially displaceable in a further coordinate perpendicular to the first coordinate, relative to the folding or cutting roller axis, is intended to be simplified so that it can be produced with little expenditure and be very simple to assemble. This is achieved in that the roller end section (13) has two parallel, plane faces (14), around which grip, on the connecting piece (5), and with an appropriate fit, two parallel engagement faces (6), which substantially grip over the width of the faces (14), of an end recess in the connecting piece (5) which permits a radial displacement of the roller (10) in the further coordinate parallel to these engagement faces (6). <IMAGE>

Description

Die Erfindung betrifft eine antriebsseitige Kupplung für mit der Antriebswelle nicht fluchtende Falz- oder Messerwellen bei Falzwerken mit einem Verbindungsstück zwischen Antriebswelle und Falzwelle, das radial zur Antriebswellenachse in einer Koordinate verschieblich, jedoch drehfest zu dieser angeordnet ist und mit einem am Falzwerkrahmen festlegbaren Lagerhebel, der eine Durchgangsbohrung für die Aufnahme eines auf der Falz- oder Messerwelle sitzenden Wälzlagers aufweist, über das ein Wellenendabschnitt der Falz- oder Messerwelle für eine Drehverbindung mit der Antriebswelle vorsteht, der mit dem relativ zur Falz-oder Messerwellenachse radial in einer weiteren, zur ersten Koordinate senkrechten Koordinate verschieblichen Verbindungsstück drehfest verbunden ist.The invention relates to a clutch on the drive side for folding or knife shafts that are not aligned with the drive shaft in folding units with a connecting piece between the drive shaft and folding shaft, which is displaceable radially to the drive shaft axis in a coordinate, but rotatably arranged therewith, and with a bearing lever that can be fixed on the folding unit frame has a through hole for receiving a roller bearing seated on the rebate or knife shaft, over which a shaft end section of the rebate or knife shaft projects for a rotary connection to the drive shaft, which with the radial relative to the rebate or knife shaft axis in a further, to the first coordinate vertical coordinate movable connector is rotatably connected.

Bei einer ersten Ausführungsform einer aus der DE-OS 23 53 961 bekannten Kupplung besteht das Verbindungsstück aus zwei Teilen. Der eine Teil des Verbindungsstücks hat eine sich in einer ersten Koordinate erstreckende radiale Nut, in welche ein auf der Antriebswelle gelagerter Fortsatz derart eingreift, daß eine Drehverbindung besteht, der Fortsatz in der radialen Nut jedoch verschieblich ist. Der andere Teil des Verbindungsstücks hat eine Bohrung, in welche der Wellenendabschnitt der Falzwelle ragt und mittels einer radialen Stiftschraube damit verbunden ist. Das der Falzwelle gegenüberliegende Ende des anderen Teils des Verbindungsstücks hat eine sich längs einer zweiten Koordinate erstreckende radiale Aussparung, die zur ersten Koordinate senkrecht verläuft. In diese radiale Aussparung ragt ein Ansatz an dem einen Teil des Verbindungsstücks derart, daß eine Drehverbindung gewährleistet ist, jedoch eine Verschiebung der beiden Teile des Verbindungsstücks längs der zweiten Koordinate möglich ist.In a first embodiment of a coupling known from DE-OS 23 53 961, the connecting piece consists of two parts. One part of the connecting piece has a radial groove extending in a first coordinate, into which an extension mounted on the drive shaft engages in such a way that there is a rotary connection, but the extension is displaceable in the radial groove. The other part of the connecting piece has a bore into which the shaft end section of the folding shaft protrudes and is connected to it by means of a radial stud screw. The end of the other opposite the folding wave Part of the connecting piece has a radial recess which extends along a second coordinate and runs perpendicular to the first coordinate. A projection on one part of the connecting piece projects into this radial recess in such a way that a rotary connection is ensured, but a displacement of the two parts of the connecting piece along the second coordinate is possible.

Diese bekannte Kupplung hat den Nachteil, daß sie herstellungstechnisch sehr aufwendig ist.This known coupling has the disadvantage that it is very complex to manufacture.

Bei einer weiteren Ausführungsform dieser Kupplung sind antriebswellenseitig zwei in Richtung der Falzwerkwelle vorstehende Klauen mit zueinander parallelen Innenflächen vorgesehen, die eine radiale Nut in einer ersten Koordinate begrenzen. In diese radiale Nut ist ein Zwischenglied so eingesetzt, daß es zwischen den Klauen drehfest gehalten ist, jedoch in der von den Klauen gebildeten radialen Nut verschieblich ist. Auf dem Wellenendabschnitt der Falzwelle ist mittels einer radialen Stiftschraube ein Verbindungsstück festgelegt, das zwei in Richtung der Antriebswelle vorstehende Klauen mit zueinander parallelen Innenflächen aufweist, die zwischen sich eine radiale Aussparung freilassen, die sich längs einer zweiten Koordinate erstreckt, die zur ersten Koordinate senkrecht verläuft. In die radiale Aussparung zwischen den Klauen des Verbindungsstücks paßt das Zwischenglied derart, daß eine drehsichere Verbindung besteht, jedoch eine radiale Relativverschiebung zwischen den Klauen und dem Zwischenglied möglich ist. Das Zwischenglied ist so bemessen, daß es in seinen Eckbereichen über die Breite bzw. Höhe der Klauen vorsteht.In a further embodiment of this coupling, two claws projecting in the direction of the folding unit shaft with mutually parallel inner surfaces are provided on the drive shaft side, which delimit a radial groove in a first coordinate. An intermediate member is inserted into this radial groove in such a way that it is held in a rotationally fixed manner between the claws, but is displaceable in the radial groove formed by the claws. On the shaft end section of the folding shaft, a connecting piece is fixed by means of a radial stud screw, which has two claws projecting in the direction of the drive shaft with mutually parallel inner surfaces, which between them leave a radial recess which extends along a second coordinate which is perpendicular to the first coordinate . The intermediate member fits into the radial recess between the claws of the connecting piece in such a way that there is a rotationally secure connection, but a radial relative displacement between the claws and the intermediate member is possible. The intermediate member is dimensioned so that it protrudes in its corner areas over the width or height of the claws.

Diese Ausführungsform der Kupplung hat zusätzlich zu dem für die Herstellung erforderlichen großen konstruktiven Aufwand den Nachteil, daß die Verschiebung der Klauen bezüglich des Zwischenglieds Begrenzungen unterliegt, sobald die Klauen bei einer entsprechenden Verschiebung an den Eckbereichen des Zwischenglieds aufeinanderstoßen.This embodiment of the coupling has the disadvantage, in addition to the large construction effort required for the production, that the displacement of the claws with respect to the intermediate member is subject to limits, so soon the claws collide with one another at the corner areas of the intermediate link.

Die der Erfindung zugrundeliegende Aufgabe besteht' riun darin, die antriebsseitige Kupplung so zu vereinfachen, daß sie mit geringerem Aufwand herstellbar ist und sehr einfach montiert werden kann.The object on which the invention is based is to simplify the drive-side coupling in such a way that it can be produced with less effort and can be assembled very easily.

Diese Aufgabe wird dadurch gelöst, daß der Wellenendabschnitt zwei parallele, ebene Flächen aufweist, die am Verbindungsstück von zwei parallelen, die Breite der Flächen erheblich übergreifenden Eingriffsflächen einer stirnseitigen, ein radiales Verschieben der Welle in der weiteren Koordinate parallel zu diesen Eingriffsflächen zulassende Aussparung im Verbindungsstück paßgerecht umgriffen sind.This object is achieved in that the shaft end section has two parallel, planar surfaces, which on the connecting piece have two parallel engaging surfaces of an end face, which considerably overlap the width of the surfaces, allowing a radial displacement of the shaft in the further coordinate parallel to these engaging surfaces in the recess in the connecting piece are gripped appropriately.

Die erfindungsgemäße antriebsseitige Kupplung hat den Vorteil, daß nur ein einziges Verbindungsstück ohne weitere Zwischenglieder genügt, um die Wirkungsweise einer Oldham-Kupplung zu gewährleisten, wobei eine äußerst einfache Montage erreicht wird, da die Falz- oder Messerwelle mit vormontiertem Lager und erforderlichenfalls mit zusätzlich angeordnetem Federring lediglich in die Durchgangsbohrung des Lagerhebels eingebracht werden muß.The drive-side coupling according to the invention has the advantage that only a single connecting piece without further intermediate links is sufficient to ensure the operation of an Oldham coupling, with extremely simple assembly being achieved since the rebate or cutter shaft has a preassembled bearing and, if necessary, an additionally arranged one Spring ring only has to be inserted into the through hole of the bearing lever.

Mit der Maßnahme nach dem Unteranspruch wird der Herstellungsaufwand weiterhin reduziert, da der Vierkant auf den Wellenendabschnitt aufgesetzt, daran angeklebt oder daran verstiftet werden kann.With the measure according to the subclaim, the manufacturing outlay is further reduced since the square can be placed on the shaft end section, glued to it or pinned to it.

Anhand der Zeichnung wird ein Ausführungsbeispiel der Erfindung näher erläutert. Es zeigen:

  • Fig. 1 schematisch in einer Draufsicht eine antriebsseitige Kupplung für eine Falzwelle und
  • Fig. 2 den Schnitt II-II von Fig. 1.
An exemplary embodiment of the invention is explained in more detail with reference to the drawing. Show it:
  • F ig. 1 schematically shows a top view of a clutch on the drive side for a folding shaft and
  • 2 shows the section II-II of Fig. 1st

Bei der in Fig. 1 gezeigten antriebsseitigen Kupplung für die Welle einer Falzwalze eines Falzwerkes ist an einem Falzwerkrahmen 1 ein Lagerhebel 2 mittels eines Bolzens 3 festgelegt. Der Lagerhebel 3 hat eine durchgehende"Stufenbohrung 4. Parallel zu dieser Stufenbohrung 4 ist ein Antriebsteil 8 ausgerichtet angeordnet, das stirnseitig zwei diametral gegenüberliegende Ansätze 9 aufweist, die mit inneren, zueinander parallelen Flächen 7 versehen sind. Zwischen diesen parallelen Flächen 7 des Antriebsteils 9 sind die parallelen Seitenflächen 15 des Verbindungsstücks 5 in Verschiebeeingriff damit angeordnet. Das Verbindungsstück 5 hat weiterhin der Bohrung 4 gegenüberliegend eine Aussparung mit parallelen gegenüberliegenden Eingriffsflächen 6, zwischen die die gegenüberliegenden Flächen 14 eines Vierkantes 13 einschiebbar sind. Die Flächen 14 des Vierkants 13 werden von den Eingriffsflächen 6 geführt. Der Vierkant 13 ist dadurch rechtwinklig zu der Wellenachse im Verbindungsstück 5 und rechtwinklig zur Verschiebung des Verbindungsstücks 5 zwischen den Ansätzen 9 des Antriebsteils 8 verschiebbar. Auf der Welle 10 ist ein Wälzlager 11 vormontiert, an dessen dem Verbindungsstück 5 zagewandter Stirnseite ein Ausgleichsfederring 12 aufgesetzt ist.In the drive-side clutch shown in FIG. 1 for the shaft of a folding roller of a folding unit, a bearing lever 2 is fixed on a folding unit frame 1 by means of a bolt 3. The bearing lever 3 has a continuous "stepped bore 4. In parallel with this stepped bore 4, a drive part 8 is arranged, which has two diametrically opposite lugs 9 on the end face, which are provided with inner, mutually parallel surfaces 7. Between these parallel surfaces 7 of the drive part 9 the parallel side surfaces 15 of the connecting piece 5 are arranged in sliding engagement therewith The connecting piece 5 furthermore has a recess opposite the bore 4 with parallel opposite engagement surfaces 6, between which the opposite surfaces 14 of a square 13 can be inserted the engagement surfaces 6. The square 13 can thereby be displaced at right angles to the shaft axis in the connecting piece 5 and at right angles to the displacement of the connecting piece 5 between the shoulders 9 of the drive part 8. A roller bearing 11 is pre-mounted on the shaft 10, on the connection of which the connecting element ngsstück 5 Zagewandter end a balance spring ring 12 is placed.

Bei der Montage der Falzwälze wird auf der Welle 10 das Wälzlager 11 mit dem Federausgleichsring 12 montiert. Die Falzwalze wird dann axial soweit verschoben, bis der Vierkant 13 durch die Bohrung 4 im Lagerhebel 1 hindurchgeht und sich in die von den Eingriffsflächen 6 gebildete Aussparung im Verbindungsstück 5 erstreckt. In dieser Montagestellung liegt der Ausgleichsfederring 12 an der Innenschulter der Bohrung 4 an, die den Außenring des Wälzlagers 11 aufnimmt.When the folding rollers are assembled, the roller bearing 11 with the spring compensation ring 12 is mounted on the shaft 10. The folding roller is then moved axially until the square 13 passes through the bore 4 in the bearing lever 1 and extends into the recess in the connecting piece 5 formed by the engagement surfaces 6. In this mounting position, the compensating spring ring 12 rests on the inner shoulder of the bore 4, which receives the outer ring of the roller bearing 11.

In Fig. 2 ist der Vierkant 13 im Querschnitt gestrichelt in einer Mittellage in der von den Eingriffsflächen 6 gebildeten Aussparung gezeigt. Bei herausgenommener Welle wird das Verbindungsstück 5 an dem Antriebsteil 9 durch einen nicht gezeigten Zapfen am Herausfallen gehindert.In Fig. 2, the square 13 is shown in dashed lines in cross-section in a central position in the recess formed by the engagement surfaces 6. With the shaft removed the connector 5 on the drive part 9 is prevented from falling out by a pin, not shown.
