Description

der gleichen Geschwindigkeit drehen soll wie das vorletzte vorangehende Rohrabschnittsglied,dann kann ein Verbleiben der resultierenden Schub. kraft in der vertikalen Symmetrieebene der Rohrabschnitte nur dann gewährleistet werden, wenn jegliches Spiel bei der Übertragung der Drehbewegungen von einem Rohrabschnitt auf den nächstfolgenden bzw. über- nächstfolgenden nahezu ausgeschaltet ist. should rotate at the same speed as the penultimate preceding pipe section member, then the resulting thrust can remain. force in the vertical plane of symmetry of the pipe sections can only be guaranteed if any play in the transfer of the rotary movements from one pipe section to the next or the next one is almost eliminated .

Zu diesem Zweck sieht die Erfindung eine Schnecken-Kegel-Radgetriebeeinheit vor, die in einem Getriebegehäuse vereinigt ist, in dem je zwei be- nachbarte , in entgegengesetzter Drehrichtung drehbare Rohrabschnitte gleitbar geführt sind, wobei die Enden der Rohrabschnitte mit Schulter- lagerflächen versehen sind, welche in der Lage sind axiale Kräfte über Wälzkörper zu übertragen und gleichzeitig die Verbindungsstellen in den Drehebenen abzudichten. For this purpose, the invention provides a worm-bevel gear unit which is combined in a gear housing in which two adjacent pipe sections, rotatable in opposite directions of rotation , are slidably guided, the ends of the pipe sections being provided with shoulder bearing surfaces, which are able to transmit axial forces via rolling elements and at the same time to seal the connection points in the planes of rotation.

äweckmäßigerweise besitzen die Rohrabschnitte elliptischen Querschnitt entsprechend den, an den schrägen Verbindungsebenen kreisförmig ausge- bildeten Drehlagern, derart, d.aß die große EllipsenachWe dem Durdfesser des kreisförmig ausgebildeten Drehlagers entspricht, Während die kleine Ellipsenachse sich aus der Schräglage der Verbindungsebene ergibt. Bei ,dem erfindungsgemäßen Getriebe liegt die Welle, auf der das Schnecken- rad und das Kegelrad angeordnet sind, in der Drehebene, in der sich das hager für die gegenseitig drehbaren Rohrabschnitte befindet. The pipe sections appropriately have an elliptical cross-section corresponding to the pivot bearings formed circularly on the inclined connecting planes , i.e. the large elliptical axis corresponds to the diameter of the circular pivot bearing, while the small elliptical axis results from the inclined position of the connecting plane. When, the transmission according to the invention, the shaft on which the worm wheel and the bevel gear is arranged, in the plane of rotation, the lean is in the for the mutually rotatable tube sections.

Dabei sieht zweckmäßigerweise die Achse, der das Schneckenrad antriebenden-Saünecke zur Drehebene, in der sich das Zager für die gegenseitig drehbarem Rohrabschnitte befindet, nicht senkrecht, sondern unter einem Winkel von weniger als QO°.@ In this case, the axis of the Saunecke driving the worm wheel is expediently not perpendicular to the plane of rotation in which the Zager for the mutually rotatable pipe sections is located, but at an angle of less than QO °. @
