Description

Das den Gegenstand der Erfindung bildende Renbradgetriebe für stufenlosen Geschwindigkeitswechsel benutzt Hohlkegelradübertragung unter Verwendung zweier Ke@gelra@dpaare. Wenn bei solchen Getrieben es auch schon erreicht ist, hohe Leistung ohne hohen Anpreßdruck oder zu .große Abmessungen zu erzielen, so bleibt doch immer noch der Mißstand bestehen, @daß bei sich steigender Leistung auch die zur Verstellung erforderlichen Kräfte anwachsen.The subject of the invention forming Renbrad gear for continuously variable Speed change uses ring-bevel gear transmission using two Ke @ gelra @ dpaare. If it has already been achieved with such transmissions, high performance To achieve without high pressure or too large dimensions, it always remains there is still the grievance @ that with increasing performance also the adjustment required forces increase.

Für die bei Verwendung zweier Kegelradpaare erzielte Verdoppelung der Leistung werden nach ,der Erfindung die Verstellkräfte :dadurch in der Höhe gehalten, idie sie für eine einfache Leistungsübertragung haben, @daß :der federnde Krafts hluß unmittelbar nur auf das eine Kegelrad und erst mittelbar über die Verbindungswelle auf das andere wirkt.For the doubling achieved when using two pairs of bevel gears According to the invention, the adjustment forces are based on performance: thereby in height held that you have for a simple power transmission, @ that: the resilient Krafts hluß directly only to one bevel gear and only indirectly via the connecting shaft affects the other.

Die Zeichnung stellt ein Ausführungsbei.spiel dar. Abb. i ist eine Seitenansicht, Abb. 2, eine -Aufsicht mit waagerechtem Teilschnitt.The drawing represents an exemplary embodiment. Fig. I is a Side view, Fig. 2, a top view with a horizontal partial section.

Die Welle 23, die mit :dem Motor 28 gekuppelt ist; trägt- in fester Drehverbindung die beiden Innenkegel 21 und 22. Der Innenkegel 21 ist auf der Welle verschiebbar, während der andere ortsfest auf ihr sitzt. Der Innenkegel2i stützt sich gegen die Feder 27, und letztere liegt gegen den Bund 4o auf der Welle 23 an. 29 und 30 .sind Lager für die Welle 23.The shaft 23 coupled to: the motor 28; carries the two inner cones 21 and 22 in a fixed rotary connection. The inner cone 21 is displaceable on the shaft, while the other is fixedly seated on it. The inner cone 2i is supported against the spring 27, and the latter rests against the collar 4o on the shaft 23 . 29 and 30 are bearings for shaft 23.

Bei Änderung ides Übersetzungsverhältnisses ist die Welle 23 mit :den Innenkegeln 21 und 22 in Pfeilrichtung b zu verschieben, während die Hohlkegel 24 und 25, die mit einem Zahnrad 26 fest verbunden sind, ortsfest :bleiben. Das Zahnrad 26 ist im Gehäuse 6i gelagert und greift in das Abtriebszahnrad 62 ein.When changing ides gear ratio, the shaft 23 is with: the To move inner cones 21 and 22 in the direction of arrow b, while the hollow cones 24 and 25, which are firmly connected to a gear 26, stationary: remain. The gear 26 is mounted in the housing 6i and meshes with the output gear 62.

Der Motor 28, die Lager 29 und 30, die Welle 23 und :dadurch die auf ihr gelagerten Innenkegel2i und 22 befinden sich auf der :gemeinsamen Platte 31. Diese ist .auf der Grundplatte 36 in Pfeilrichtung b durch die Führung 37 und die Flachführung 38 und 39 verschiebbar. Zur Verschiebung dient das Handrad 33, dessen Welle 35 über ein Kegelra:dgetriebe 34 auf eine Spindel 32 wirkt, die an der Platte 3 i angreift.The motor 28, the bearings 29 and 30, the shaft 23 and: thereby the on their supported inner cone 2i and 22 are on the: common plate 31. This is .auf the base plate 36 in the direction of arrow b through the guide 37 and the Flat guide 38 and 39 can be moved. To move the handwheel 33 is used, its Shaft 35 acts via a bevel gear 34 on a spindle 32 which is attached to the plate 3 i attacks.

Bei dieser Durchbildung verbleiben die Verstellkräfte in der Höhe, die sie für eine einfache Leistungsübertragung besitzen, also bei Anwendung nur eines ,Kegelpaares untergleichen Verhältnissen. Somit bedeutet der Leistungszuwachs auf den doppelten Wert keinen nachteiligen Zuwachs der Verstellkräfte.With this development, the adjustment forces remain at the level which they have for simple power transmission, i.e. when using only one, pair of cones under the same conditions. Thus the increase in performance means to double the value no disadvantageous increase in the adjustment forces.
