Die beiden Vertikalwalzringe VWR1 und VWR2 nach Fig. 1 sind auf Walzentragwellen WTW1 und WTW2 aufgeschoben, die jeweils in einem der beiden, auf nicht dargestellte Weise horizontal gegeneinander und voneinander weg verschiebbaren Lagereinbaustücke LES1 und LES2 lagern. Unter diesen sind zwei Getriebegehäuse GG1 und GG2 angeordnet und mit dem jeweiligen Lagereinbaustück LES1 bzw. LES2 formschlüssig verbunden. In diesem lagert vertikal je eine Kegelradwelle KW1 bzw. KW2 mit nach unten gerichteten Kegelrädern KR1 bzw. KR2. Diese kämmen (vergl. Fig. 2) mit Kegelrädern KR3 bzw. KR4 von horizontal und koaxial zueinander in den Getriebegehäusen GG1 bzw. GG2 gelagerten Kegelradhohlwellen KHW3 bzw. KHW4. Die eine der Kegelradhohlwellen KHW3 ist mit einer Antriebsspindel ASP axial verschiebbar gekuppelt. Beide Kegelradhohlwellen KHW3 und KHW4 weisen innenseitig jeweils eine Zahnwellenprofilierung ZPI3 bzw. ZPI4 auf. In diesen Zahnwellenprofilierungen ist eine Zwischenwelle axial schwimmend verschiebbar, deren Endabschnitte ZWA3 und ZWA4 mit außenseitigen Zahnwellenprofilierungen ZPA3 bzw. ZPA4 in die innenseitigen Zahnwellenprofilierungen ZPI3 bzw. ZPI4 der Kegelradhohlwellen KHW 3 bzw. KHW4 eingreifen und in diesen axial verschiebbar sind.The two vertical rolling rings VWR1 and VWR2 according to FIG. 1 are on roller supporting shafts WTW1 and WTW2 deferred, each in one of the two, not on illustrated manner horizontally displaceable against and away from each other Store bearing chocks LES1 and LES2. Among these are two gearboxes GG1 and GG2 arranged and with the respective bearing chock LES1 or LES2 positively connected. A bevel gear shaft is supported vertically in this KW1 or KW2 with bevel gears KR1 or KR2 directed downwards. These mesh (see FIG. 2) with bevel gears KR3 and KR4 from horizontal and Bevel gear hollow shafts mounted coaxially to one another in the gearbox housings GG1 or GG2 KHW3 or KHW4. One of the bevel gear hollow shafts KHW3 is with a drive spindle ASP coupled axially displaceable. Both hollow bevel gear shafts KHW3 and KHW4 each have a ZPI3 splined profile on the inside or ZPI4. An intermediate shaft is axial in these toothed shaft profiles floating, the end sections ZWA3 and ZWA4 with outside Spline profiles ZPA3 or ZPA4 in the inside splines Engage ZPI3 or ZPI4 of the bevel gear hollow shafts KHW 3 or KHW4 and are axially displaceable in these.
