Description

Man kennt bereits ein stufenlos regelbares Keilriemenwechselgetriebe mit axial gegeneinander verschiebbaren Kegelscheiben auf der An- und Abtriebswelle und mit axial verschiebbarer Doppelkegelscheibe auf einer Zwischenwelle, wobei die axial verschiebbare Doppelkegel'scheibe und die axial verschiebbaren Einzelkegelscheiben gemeinsam durch eine Verstellvorrichtung verschoben werden.One already knows an infinitely variable V-belt change gear with axially against each other displaceable conical pulleys on the input and output shaft and with axially displaceable Double conical disc on an intermediate shaft, the axially displaceable double conical disc and the axially displaceable Individual conical disks can be moved together by an adjusting device.

Ein solches Keilriemengetriebe, das in Verbindung mit einem Differentialgetriebe als Wechsel- und Wendegetriebe in Vorschlag gebracht wurde, läßt jedoch die Übertragung einer größeren Leistung nicht zu und beschränkt sich überdies auf zwei Übersetzungsstufen. Ferner ergibt sich bei dem erwähnten bekannten Getriebe infolge der fluchtenden Anordnung von An- und Abtriebswelle eine verhältnismäßig große Baulänge, während bei Fortfall des dort verwendeten Differentialgetriebes die Lagerung der gegeneinandergerichteten Enden von Anr und Abtriebswelle erhebliche Schwierigkeiten bereiten würde, sofern man nicht eine wesentliche und an sich nutzlose Verbreiterung der auf der Zwischenwelle vorgesehenen Doppelkegelscheibe mit in Kauf nehmen wollte.Such a V-belt drive, which has been proposed in connection with a differential gear as a change and reversing gear, however, does not allow the transmission of greater power and is moreover limited to two gear ratios. In addition, result of the aforementioned known transmission due to the aligned arrangement of input and output shaft, a relatively large overall length, while elimination of the differential gear used therein, the storage of the mutually facing ends of at r and the output shaft would create significant difficulties, one unless a substantial and wanted to take into account useless widening of the double conical disk provided on the intermediate shaft.

Demgegenüber besteht die vorliegende Erfindung darin, daß bei paralleler ,(nicht fluchtender) Anordnung von An-, Abtriebs- und Zwischenwellen zueinander auf. der An- und Abtriebswelle mehrere Kegelscheibenpaare und auf der bzw. den Zwischenwellen mehrere Doppelkegelscheiben nebeneinander vorgesehen sind, wobei die verschiebbaren Kegelscheiben aller Wellen in an sich bekannter Weise gruppenweise miteinander verbunden sind.In contrast, the present invention consists in the fact that with parallel, (not aligned) Arrangement of input, output and intermediate shafts to each other. several pairs of conical pulleys on the input and output shaft and a plurality of double cone pulleys are provided next to one another on the intermediate shaft or shafts are, the displaceable conical pulleys of all shafts in per se known Way are connected in groups.

Auf diese Weise ergibt sich der Vorteil, daß ein Keilriemenwechselgetriebe von großer Leistung und weitem Regelbereich in stark gedrängter Bauart zustande kommt, das beispielsweise für Werkzeugmaschinen, Textilmaschinen, Papierverarbeitungsmaschinen und für viele andere Zwecke besonders brauchbar ist.In this way, there is the advantage that a V-belt change transmission of large Power and a wide control range in a very compact design comes about, for example particularly useful for machine tools, textile machines, paper processing machines and for many other purposes is.

Ein in weiten Grenzen regelbares K'eilriemengetriebe bei paralleler Anordnung von An-, Abtriebs- und Zwischenwelle hat zwar als bekannt zu gelten, jedoch wurden dort auf der Zwischenwelle nur Einzelkegelscheiben verwendet, wodurch sich der erhebliche Nachteil ergibt, daß die Baulänge des Getriebes sehr groß ausfällt. Anderseits kennt man auch schon Keilriemenwechselgetriebe mit Doppelkegelscheiben auf der Zwischenwelle, doch' wurden im letzteren Falle die Kegelscheiben auf der An- und Abtriebswelle nicht verstellbar ausgebildet, so daß dieses Getriebe nur einen kleinen Regelbereich umfaßt und sichA V-belt drive that can be regulated within wide limits if the input, output and intermediate shafts are arranged in parallel, this is to be regarded as known, but there were on the intermediate shaft only uses single tapered disks, which has the significant disadvantage shows that the overall length of the transmission is very large. On the other hand, one also knows V-belt change gearbox with double cone pulleys on the intermediate shaft, but ' In the latter case, the conical disks on the input and output shafts were not adjustable designed so that this transmission includes only a small control range and itself

schon aus diesem Grunde in der Praxis nicht durchsetzen konnte.for this reason alone could not prevail in practice.

to zu den vorgenannten drei Wellen parallele Abtriebswelle W3. Statt durch einen Motor kann der Antrieb auch auf andere Weise erfolgen, z. B. durch Riemenscheibe oder Zahnrad. Die auf der Welle w sitzenden Scheiben- paare α und b treiben über die Gegenpaare c und d auf die Welle W1, die Weiterleitung erfolgt durch die Scheibenpaare e, f und g über Gegenpaare h, i und k nach Welle W2 und von hier durch die Scheibenpaare p, q, r und s to the aforementioned three shafts parallel output shaft W 3 . Instead of a motor, the drive can also take place in other ways, e.g. B. by pulley or gear. The pairs of disks α and b sitting on the shaft w drive via the opposing pairs c and d onto the shaft W 1 , the transmission takes place through the disk pairs e, f and g via opposing pairs h, i and k to shaft W 2 and from here by the disk pairs p, q, r and s

2« über die vier gleichen Gegenpaare u auf die Welle wa. Der Abtrieb kann von hier aus direkt durch eine Riemenscheibe, Zahnrad oder Kupplung erfolgen. In dem gezeigten Beispiel ist zwischen der austreibenden Riemenscheibe ν und Welle W3 eine Zahnraduntersetzung Z1, S2 eingeschaltet, was zweckmäßig sein wird, wenn die mittlere austreibende Drehzahl innerhalb des Gesamtregelbereichs wesentlich unter der konstanten Motordrehzahl liegt. Durch die abwechselnde Anordnung der Übertragungselemente auf den Zwischenwellen W1 und ZW2 können nun die Scheibenhälften c-e, e-d, d-f ferner p-h, h-q, q-i, i-r, r-k und k-s zu je einer doppelkegelförmi-■ gen Scheibe vereinigt werden, die nun zusammen mit den übrigen Scheibenhälften durch die Stellbolzen Ji1 bis St8 zu bestimmten Gruppen zusammengefaßt werden. Auf jeder Welle entsteht eine feststehende Gruppe, die mit der äußeren Scheibe an einem Bund der Welle anliegt, gegen den sie infolge der Keilw'irkung der Übertragungsmittel ständig festgehalten wird. Eine Verbindung der einzelnen Gruppen erübrigt sich durch diese An-Ordnung. Im Beispiel sind dies folgende Gruppen: Welle«;: rechte Scheibenhälfte α und b, verbunden durch die Stellbolzen St1; WeIIeW1: c links, e-d, f und g rechts durch Stellbolzen Ji3; WeIIeW2: p-h, q-i, r-k und ί2 «over the four identical opposing pairs u onto the shaft w a . The output can take place from here directly through a belt pulley, gearwheel or coupling. In the example shown, a gear reduction Z 1 , S 2 is switched on between the driving pulley ν and shaft W 3 , which will be useful if the mean driving speed within the overall control range is significantly below the constant engine speed. Due to the alternating arrangement of the transmission elements on the intermediate shafts W 1 and ZW 2 , the disk halves ce, ed, df, ph, hq, qi, ir, rk and ks can each be combined to form a double-conical disk, which is now combined with the remaining disc halves can be combined into specific groups by adjusting bolts Ji 1 to St 8. A fixed group is created on each shaft, which rests with the outer disk on a collar of the shaft, against which it is constantly held due to the wedge effect of the transmission means. A connection between the individual groups is unnecessary through this arrangement. In the example these are the following groups: Shaft «;: right disk halves α and b, connected by the adjusting bolts St 1 ; WeIIeW 1 : c left, ed, f and g right by adjusting bolt Ji 3 ; WeIIeW 2 : ph, qi, rk and ί

Die Stellbolzen Ji2, Ji4, Ji6 und Ji8 sind mit den verschiebbaren Lauf ringen der Lager /, Z1, I2 und I3 fest verbunden, während die Außenringe der Lager mittels Stellmuttern χ mit der Stellscheibe η fest verbunden sind. Diese Anordnung gestattet sowohl ein hinreichendes Auseinanderziehen der Scheibenhälften, um die Übertragungsmittel ein- und ausbauen zu können, als auch eine gegenseitige Einstellung der Scheibenhälften zwecks Nachspannung der Übertragungsmittel. Die Verstellung der Scheibe η geschieht durch die zentral angeordnete Zahnstange ^1 und das Zahnrad y2, welches mit einem Handrad oder Hebel in Verbindung steht und somit von Hand oder, falls die Regulierung selbsttätig erfolgen soll, mechanisch betätigt werden kann.Fellbolzen St 2 , shaft W 1 : ce, df, g left by adjusting bolts Ji 4 , WeIIeW 2 : ρ left, hq, ir, ks by adjusting bolts Ji 8 and shaft w s : all right disk halves 11 by adjusting bolts Ji 8 . The adjusting bolts Ji 2 , Ji 4 , Ji 6 and Ji 8 are firmly connected to the sliding barrel rings of the bearings /, Z 1 , I 2 and I 3 , while the outer rings of the bearings are firmly connected to the adjusting disk η by means of adjusting nuts χ. This arrangement allows both a sufficient pulling apart of the disk halves in order to be able to install and remove the transmission means, as well as a mutual adjustment of the disk halves for the purpose of retensioning the transmission means. The adjustment of the disk η is done by the centrally arranged rack ^ 1 and the gear y 2 , which is connected to a handwheel or lever and can therefore be operated manually or, if the regulation is to take place automatically, mechanically.
