Description

Gleichachsiges Mehrfachschneckengetriebe In dem Patent 938 453 wurde bereits darauf hingewiesen, daß eine Verdoppelung der zu übertragenden Leistung durch Parallelschaltung zweier Fünfganggetriebe mit gemeinschaftlichem An- und Abtrieb erzielt werden kann. Es ist außerdem bereits bekannt, daß auch durch Eingriff mehrerer Vollschnecken in ein gemeinsames Schneckenrad eine Erhöhung des Drehmoments an der getriebenen Welle zu erzielen ist.Coaxial multiple worm gear In the patent 938 453 was already pointed out that a doubling of the power to be transmitted by connecting two five-speed transmissions in parallel with a common input and output can be achieved. It is also already known that even by the intervention of several Full worms in a common worm wheel increase the torque on the driven shaft is to be achieved.

Gegenstand der Zusatzerfindung ist nachfolgend beschriebene Anordnung, durch die eine Verdoppelung bzw. Vervierfachung des zu übertragenden Drehmoments erzielt wird.The subject of the additional invention is the arrangement described below, by doubling or quadrupling the torque to be transmitted is achieved.

Nach Abb. 1, 2 und 3 werden um die halbierte Antriebs-Globoidschnecke zwei, drei bzw. vier Schneckenräder 4 unter einem Winkel von 180, 120 bzw. 90° angeordnet. Durch einen derartigen Konstruktionsschritt kann das zu übertragende Drehmoment verdoppelt, verdreifacht bzw. vervierfacht werden. Die Anordnung läßt sich sowohl bei dem gleichachsigen Doppelschneckengetriebe als auch bei dem Wendegetriebe gemäß dem Hauptpatent 938 453 durchführen. Zur Erzielung eines gleichzeitigen einwandfreien Eingriffs von zwei, drei oder vier Schneckenrädern ist es notwendig, daß bei zwei Schneckenrädern Schnecken-und Schneckenradzähnezahl durch Zwei, bei drei Schneckenrädern Schnecken- und Schneckenradzähnezahl durch Drei und bei vier Schneckenrädern Schnekken- und Schneckenradzähnezahl durch Vier teilbar ist. Günstige Verzahnungsverhältnisse ergeben sich, wenn der Schneckendurchmesser gegenüber dem Schneckenraddurchmesser möglichst groß gewählt wird, d. h. wenn die Teilkreise der Antriebsgloboidschnecke 3 und der des Schneckenrades 4 etwa gleich sind.According to Fig. 1, 2 and 3 are the halved drive globoid worm two, three or four worm wheels 4 arranged at an angle of 180, 120 or 90 °. With such a construction step, the torque to be transmitted doubled, tripled or quadrupled. The arrangement can be both in the coaxial twin worm gear as well as in the reversing gear according to carry out the main patent 938 453. To achieve a simultaneous flawless Engagement of two, three or four worm gears, it is necessary that with two Worm gears Worm and worm gear teeth number by two, with three worm gears Number of worm and worm gear teeth by three and, with four worm gears, worm gear and number of worm gear teeth is divisible by four. Favorable gear ratios arise when the worm diameter is compared to the worm wheel diameter is chosen as large as possible, d. H. if the pitch circles of the drive globe worm 3 and that of the worm wheel 4 are approximately the same.

PATENTANSPRUCH: Gleichachsiges Doppelschneckengetriebe, bei dem eine antreibende halbgeteilte Globoidschnecke mit einem Schneckenrad, das mit je einer stark zueinander abgewinkelten Schneckenrad- und Schnekkenverzahnung versehen ist, im Eingriff steht, nach Patent 938 453, dadurch gekennzeichnet, daß um die halbgeteilte Antriebsgloboidschnecke (3) zwei, drei oder vier Schneckenräder (4) angeordnet sind, die wiederum gemeinsam in die getriebene Globoidschnecke (7) eingreifen, zur Verdoppelung, Verdreifachung bzw. Vervierfaehung des zu übertragenden Drehmoments. In Betracht gezogene Druckschriften: Deutsche Patentschriften Nr. 356 797, 384 923.PATENT CLAIM: Coaxial twin worm gear with one driving half-divided globoid worm with a worm wheel, each with one worm gear and worm gear teeth that are strongly angled to one another, is in engagement, according to patent 938 453, characterized in that around the half-divided Drive globe worm (3) two, three or four worm wheels (4) are arranged, which in turn jointly engage in the driven globoid worm (7) to double Tripling or quadrupling of the torque to be transmitted. Into consideration Drawn pamphlets: German Patent Nos. 356 797, 384 923.
