Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung bezieht sich auf Riemenoder Seilscheibengetriebe, durch deren Verschiebung das Übersetzungsverhältnis geändert werden kann. Das Neue ist darin zu erblicken, daß die verwendeten Leitrollen zwecks Spannungsregelung der Riemenverwindung zwangsweise folgen können.The invention relates to belt or pulley drives, by shifting them the gear ratio can be changed. The new is to be seen in that the guide rollers used can forcibly follow the belt twist for the purpose of regulating the tension.

Die Neuerung ist auf der Zeichnung in den Fig. ι und 2 in zwei Ausführungsbeispielen ίο dargestellt.The innovation is shown in the drawing in FIGS. Ι and 2 in two exemplary embodiments ίο shown.

Ausführungsbeispiel Fig. i:Embodiment Fig. I:

Um den Riemen von den konischen Scheiben I, 2 nach der Treibscheibe 4 zu leiten, finden an sich bekannte Leitrollen 5 Verwendung, die bei Änderung des Übersetzungsverhältnisses des Wechselgetriebes mit ihren Büchsen 9 drehbar auf den schräg aufsteigenden Zapfen 8 gelagert sind und bei Bewegung des Schalthebels 6 durch die Kniehebel 7 und Zugstangen 13 auf den schrägen Zapfen 8 derart verschoben werden, daß der Riemen stets straff gespannt bleibt. Damit aber auch die Leitrollen 5 ihre achsiale Stellung, entsprechend der Verwindung des Riemens, ändern können, sind an den Büchsen 9 Nasen 10 angebracht, die beim Aufsteigen der Leitrollen letztere durch die schrägen Flächen 11 achsial zur Seite drehen.To guide the belt from the conical pulleys I, 2 to the drive pulley 4, found per se known guide rollers 5 use that when changing the transmission ratio of the gearbox with their sleeves 9 are rotatably mounted on the inclined rising pin 8 and when the Shift lever 6 through the toggle lever 7 and tie rods 13 on the inclined pin 8 in this way be moved so that the belt is always taut. But so does the Guide rollers 5 change their axial position according to the twisting of the belt can, 9 noses 10 are attached to the bushes, when the guide rollers rise Rotate the latter axially to the side through the inclined surfaces 11.

Claims (1)

Patent-Anspruch:Patent claim: Ausführungsbeispiel Fig. 2:Embodiment Fig. 2: Sollen zwecks Änderung des Übersetzungsverhältnisses des Wechselgetriebes beide Kegel i, 2 gegeneinander verschoben werden, dann entspricht dies der Einrichtung Fig. 2, nach welcher durch das Handrad 10 die Schalthebel 6 die beiden Kegel 1, 2 in Richtung der Pfeile gegeneinander bewegen, während das Zahngetriebe 8 durch die Zugstange 7 die Leitrollen 5 mit dem Prisma 9 auf dem feststehenden Schlitten 11 verschiebt. Die Zapfen 12 sitzen gleichfalls gelenkig an dem Prisma 9, um der Verwindung des Riemens 3 folgen zu können.Should both cones change the transmission ratio of the gearbox i, 2 are shifted against each other, then this corresponds to the device in Fig. 2, after which by the handwheel 10, the switching lever 6, the two cones 1, 2 in the direction the arrows move against each other, while the gear mechanism 8 through the tie rod 7 the Guide rollers 5 with the prism 9 on the stationary slide 11 moves. The cones 12 are also seated in an articulated manner on the prism 9 in order to prevent the belt 3 from being twisted to be able to follow.
