Description

Es ist bereits ein stufenlos verstellbares Regelgetriebe mit zwei Kegelscheiben bekannt, bei dem der Antriebsmotor, dessen Welle die eine Kegelscheibe trägt, auf einer Schwinge gelagert ist, deren Welle in einem Schlitten befestigt ist. Zur Verstellung des Getriebes kann der Schlitten durch eine besondere Verstellspindel verschoben werden. Das Gewicht des Motors drückt die ihm zugeordnete Reibscheibe gegen die andere. Durch das Reaktionsdrehmoment wird der Anpreßdruck noch verstärkt. Die Erfindung besteht darin, die Schwingenwelle des Motors unmittelbar in der Grundplatte des Getriebes verschiebbar zu lagern. Sodann kommen der Schlitten und seine Verstellspindel in Wegfall, so daß das Getriebe vereinfacht und verbilligt wird.It is already an infinitely variable control gear with two Conical pulleys known, in which the drive motor, the shaft of which is a conical pulley carries, is mounted on a rocker, whose shaft is fixed in a slide is. The slide can be adjusted using a special adjusting spindle be moved. The weight of the motor presses the friction disk assigned to it against the other. The contact pressure is increased by the reaction torque. The invention consists in the swing shaft of the motor directly in the base plate of the gearbox to be slidable. Then come the slide and its adjusting spindle in omission, so that the transmission is simplified and cheaper.

In der Zeichnung ist ein solches Regelgetriebe im Horizontalschnitt schematisch dargestellt.In the drawing, such a control gear is shown in horizontal section shown schematically.

Die Veränderung der Abtriebsdrehzahlen geschieht in folgender Weise: Durch Rechtsdrehen des Handrades t wird die mit Gewinde versehene, in der Getriebegrundplatte gelagerte Pendelwelle 2 mit der daran befestigten Motorwippe 3 axial nach links verschoben. Der Motor 4, auf dessen Welle der Antriebskegels aufgesetzt ist, ist auf der Wippe 3 montiert und erhält somit die gleiche axiale Verschiebung. Der Antriebskegel s wird durch die Eigengewichte von Motox und Wippe auf die Reibfläche des Abtriebshohlkegels 6 aufgedrückt. Der Abtriebshohlkegel6 ist auf einer Welle 7 in der Gehäusegrundplatte 8 gelagert. Durch die bei der Verschiebung erfolgende Triebkreiszunahme des Antriebskegels 5 muß von letzterem eine weitere oszillierende Bewegung nach oben ausgeführt werden. Diese Bewegung wird ganz automatisch beim Verschieben der Pendelwelle 2 ausgelöst.The output speeds are changed in the following way: By turning the handwheel t clockwise, the threaded in the gearbox base plate mounted pendulum shaft 2 with the attached motor rocker 3 axially to the left postponed. The motor 4, on whose shaft the drive cone is placed, is mounted on the rocker 3 and thus receives the same axial displacement. The drive cone s is due to the dead weight of Motox and rocker on the friction surface of the hollow output cone 6 pressed on. The hollow output cone 6 is on a shaft 7 in the housing base plate 8 stored. Due to the increase in the drive circle of the drive cone during the shift 5 a further oscillating movement upwards has to be carried out by the latter. This movement is triggered automatically when the pendulum shaft 2 is moved.

Durch Zusatzgewichte oder Federn kann erforderlichenfalls der Anpreßdruck zwischen den beiden Kegelreibscheiben erhöht werden.If necessary, the contact pressure can be increased by additional weights or springs be increased between the two conical friction disks.

In Fällen, wo die verlangte Abtriebsdrehzahl sehr niedrig liegt, kann durch nachgeschaltete Zahnradvorgelege die Untersetzung beliebig vergrößert werden.In cases where the required output speed is very low, can the reduction can be increased as required by downstream gear reduction.
