Description

Bei gewöhnlichen Rad- oder Schneckengetrieben ist stets eine geringe Zahnluft vorhanden, die sich jedoch für bestimmte Zwecke sehr störend bemerkbar macht, was seine Ursache darin hat, daß ^besonders bei geringer Kraftübertragung die Wellen kleine VOr- und Rückwärtsbewegungen machen können. Um die mit dem Zahnspiel verbundenen Nachteile •zu Beseitigen, wird erfindungsgemäß das Getriebe mit einem federnden Ausgleich versehen, der in der Zeichnung -an einein Schneckengetriebe beispielsweise bildlich dargestellt ist. Die Zeichnung zeigt das Getriebe einmal im Axialschnitt und einmal in perspektivischer Ansicht.With ordinary wheel or worm gears there is always a small amount of tooth clearance, which, however, makes itself very disturbing for certain purposes, which is its cause has therein that ^ especially with low power transmission the waves small front and back Be able to make backward movements. To the disadvantages associated with the backlash • To eliminate, according to the invention, the gearbox is provided with a resilient compensation, which in the drawing -an einin worm gear, for example, is shown pictorially is. The drawing shows the transmission once in an axial section and once in a perspective view.

Auf der Achse a sitzt ein Schneckenrad, welches in seiner Ebene, wie an sich bekannt, geteilt und dessen eine Hälfte b auf der Welle a befestigt ist. Die andere Hälfte des Schneckenrades c ist drehbar auf der Welle a angeordnet und hat einen Halsii, auf dem die Druck- und Drehfeder e festsitzt. Das andere Ende dieser Feder e sitzt fest auf dem -Stellring/, der seinerseits fest auf der Welle λ sitzt, sich aber in Längs- und Drehrichtung verstellen läßt. Bei Eingriff der Schnecke g in das geteilte Schneckenrad b und c kann durch Verstellen des Stellringes/ in Längsund Drehrichtung die zur Welle gleichachsige Schraubenfeder e axial so angepreßt und gleichzeitig so unter Drehspannung gesetzt werden, daß die praktisch unvermeidliche Zahnluft zwischen Schnecke "und Schneckeniad beseitigt wird. Oer Erfindungsgedanke ist sowohl auf Schnecken- als. auch auf Radgetriebe anwendbar.On the axis a sits a worm wheel, which, as is known per se, is divided in its plane and one half b of which is attached to the shaft a. The other half of the worm wheel c is rotatably arranged on the shaft a and has a neck ii on which the compression and torsion spring e is fixed. The other end of this spring e sits firmly on the adjusting ring /, which in turn sits firmly on the shaft λ, but can be adjusted in the longitudinal and rotational directions. When the worm g engages in the divided worm wheel b and c , the coaxial helical spring e, which is coaxial with the shaft, can be pressed axially by adjusting the adjusting ring / in the longitudinal and direction of rotation and at the same time placed under torsional stress in such a way that the practically unavoidable tooth clearance between the worm and the worm gear is eliminated The idea of the invention can be applied to worm gears as well as to wheel gears.
