Abstract

Die Erfindung betrifft eine Vorrichtung zum Verstellen der Falzmechanismen an einem Falzzylinder eines Falzapparates mit zwei ineinandergeschachtelten, jeweils Falzmechanismen tragenden, koaxialen, in Umfangsrichtung zueinander verstellbaren Zylinderkörpern, mit zwei jeweils mit den Zylinderkörpern verbundenen Antriebszahnrädern gleicher Zähnezahl und mit einem mit den Antriebszahnrädern in Verbindung stehenden, die Verstellung der Zylinderkörper bewirkenden Differentialgetriebe. Um eine Vorrichtung zu schaffen, die mit relativ wenigen Bauteilen und Zahneingriffen der Bauteile einen einfachen, platzsparenden Aufbau und ein geringes Spiel zwischen den Bauteilen besitzt, ist von einem an sich bekannten, mit einer Stellwelle (29) für ein elliptisches, als Wave Generator (30) bezeichnetes Teil, mit einem auf dem Wave Generator (30) verdrehbar angeordneten, radial elastisch verformbaren, außenverzahnten, ringförmigen, als Flexible Spline (31) bezeichneten Teil und mit einem innenverzahnten, in den Flexible Spline (31) eingreifenden, gegenüber diesem eine größere Zähnezahl besitzenden, mit einer Außenverzahnung in das Antriebszahnrad (22 bzw. 26) eines Zylinderkörpers (7 bzw. 10) eingreifenden, als Circular Spline (32) bezeichneten Außenring ausgestatteten Harmonic Drive-Getriebe (X; X') der Flexible Spline (31) mit einem analog zum Circular Spline (32) koaxial angeordneten Zahnrad (33) fest verbunden, das mit einer die Übersetzung zwischen dem Flexible Spline (31) und dem Circular Spline (32) zurückübersetzenden Zähnezahl ausgestattet in das Antriebszahnrad (23 bzw. 24) des anderen Zylinderkörpers (8 bzw. 9) ein Übersetzungsverhältnis 1:1 zwischen den beiden Antriebszahnrädern (22; 23 bzw. 26; 24) bewirkend eingreift, wobei der Unterschied zwischen den Zähnezahlen der Außenverzahnung des Circular Spline (32) und dem Zahnrad (33) mittels einer Profilverschiebung gleiche Achsabstände des Circular Spline (32) und des Zahnrades (33) zu den Antriebszahnrädern (22; 23 bzw. 26; 24) realisierend kompensiert ist.

Figure 00000001
The invention relates to a device for adjusting the folding mechanisms on a folding cylinder of a folding apparatus with two nested, each carrying folding mechanisms, coaxial, circumferentially adjustable cylinder bodies, with two drive gears connected to the cylinder bodies of the same number of teeth and with one connected to the drive gears. the adjustment of the differential gear effecting the cylinder body. In order to create a device that has a simple, space-saving structure and a small clearance between the components with relatively few components and tooth meshing of the components, a device known per se, with an adjusting shaft (29) for an elliptical, as a wave generator ( 30) designated part, with a rotatably arranged on the wave generator (30), radially elastically deformable, externally toothed, ring-shaped, designated as flexible spline (31) and with an internally toothed, engaging in the flexible spline (31), with respect to this one Larger number of teeth, with an external toothing engaging in the drive gear (22 or 26) of a cylinder body (7 or 10), outer ring designated as circular spline (32) equipped with the Harmonic Drive gear (X; X ') of the flexible spline (31 ) with a gear (33) coaxially arranged analogously to the circular spline (32), which with a translation between the flexible sp line (31) and the circular spline (32) back-translating number of teeth equipped in the drive gear (23 or 24) of the other cylinder body (8 or 9) a transmission ratio 1: 1 between the two drive gears (22; 23 and 26; 24) engages, whereby the difference between the number of teeth of the external teeth of the circular spline (32) and the gear (33) by means of a profile shift equals the center distances of the circular spline (32) and the gear (33) to the drive gears (22; 23 and . 26; 24) is realizingly compensated.
