Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es sind Treibscheiben von veränderlichem Durchmesser bekannt geworden, die aus zwei durch parallele Stäbe mit einander verbundenen Platten oder Kränzen bestehen. Diese Stäbe sind an den Platten so nachgiebig befestigt, dafs ihre kürzeste Entfernung von der Drehachse der Scheibe sich ändert, sobald eine der beiden Platten gegen die andere gedreht wird, wobei die Stäbe die bekannte Form eines Hyperboloides umhüllen.There are traction sheaves of variable diameter are known, which consist of two consist of parallel bars with interconnected plates or wreaths. These bars are so flexibly attached to the plates that their shortest distance from the axis of rotation the disc changes as soon as one of the two plates is turned against the other, the rods enveloping the familiar shape of a hyperboloid.

Für den praktischen Gebrauch, z. B. für die Verwendung zur Erzielung einer veränderlichen Uebersetzung, ist hierbei aber der Umstand sehr störend, dafs bei der Drehung der betreffenden Platte der Abstand beider Platten von einander sich ändert, also eine Verschiebung einer Platte oder beider auf der Welle stattfinden mufs. Ferner verschiebt sich bei einer Verstellung des Durchmessers jedesmal die Stelle der stärksten Einschnürung, also diejenige, auf der das Seil oder sonstige Zugmittel· läuft.For practical use, e.g. B. for use to achieve a variable Translation, the fact that the rotation of the relevant Plate the distance between the two plates changes, i.e. a shift one plate or both must take place on the shaft. Furthermore, shifts with one Adjustment of the diameter each time the point of the strongest constriction, i.e. the one on which the rope or other traction device · runs.

Den Gegenstand der Erfindung bildet eine Scheibe der erwähnten Art, bei der solche Verschiebungen nicht stattfinden.The subject of the invention forms a disc of the type mentioned, in which such Shifts do not take place.

Die Zeichnung zeigt eine solche Scheibe. Die einander parallelen Stäbe c sind an der Scheibe a, die fest auf der Welle sitzt, gelenkig befestigt. Die Scheibe b ist auf der Welle drehbar, aber nicht verschiebbar. Die Stäbe c sind durch entsprechende Durchbohrungen der Scheibe b hindurchgesteckt, derart, dafs sie sich mehr oder weniger hindurchschieben können. Zu diesem Zwecke sind die Löcher nach beiden Seiten hin stark abgerundet bezw. kegelartig erweitert. Auch kann man diese Löcher mit Kugelschalen ausrüsten, die eine allseitige Bewegung der Stäbe unter sicherer Führung gestatten.The drawing shows such a disk. The mutually parallel rods c are articulated to the disk a, which is firmly seated on the shaft. The disk b is rotatable on the shaft, but not displaceable. The rods c are inserted through corresponding bores in the disk b in such a way that they can more or less slide through. For this purpose, the holes are strongly rounded BEZW on both sides. widened like a cone. These holes can also be equipped with spherical shells that allow the rods to move in all directions while being safely guided.

Die Drehung und Feststellung der Platten ist auf verschiedene und sehr einfache Weise herbeizuführen.The rotation and locking of the panels is different and very simple bring about.

Claims (1)

Patent-Anspruch :Patent claim: Eine verstellbare Hyperboloidscheibe aus zwei Platten oder Kränzen und sie verbindenden parallelen Stäben, dadurch gekennzeichnet, dafs die Stäbe durch Bohrungen der einen Scheibe hindurchtreten, derart, dafs die Verstellung des wirksamen Durchmessers lediglich durch Drehen ohne gleichzeitiges Verschieben der Platte oder des Kranzes bewirkt werden und eine Ortsveränderung der Mittellinie des Seiles, Riemens u. s. w. vermieden werden kann.An adjustable hyperboloid disc made of two plates or rings and connecting them parallel rods, characterized in that the rods through holes in one disc pass through, in such a way that the adjustment of the effective diameter is only possible by turning be effected without simultaneous displacement of the plate or the rim and a change in location the center line of the rope, belt, etc. can be avoided.
