Abstract

Verfahren zur Herstellung globoider Schnecken, dadurch gekennzeichnet, dass die zu fertigende Schnecke 1 von mindestens einer Walze 2 mit Zähnen durch eine translatorische und/oder rotatorische Bewegung in Walzenachsrichtung und gleichzeitige Drehung 4 der Schnecke 1 um die Schneckenachse so umgeformt wird, dass ein Zahnprofil auf der Schnecke entsteht.A method for producing globoider screws, characterized in that the to be manufactured screw 1 of at least one roller 2 with teeth by a translational and / or rotational movement in Walzenachsrichtung and simultaneous rotation 4 of the screw 1 is converted to the screw axis so that a tooth profile the snail arises.

Description

Hiermit wird gleichzeitig der Rechercheantrag gestellt.Herewith the search request is submitted at the same time.

Schneckengetriebe mit globoiden Schnecken sind seit längerem in der Literatur bekannt. Sie zeichnen sich durch eine höhere Tragfähigkeit und bessere Wirkungsgrade aus, als vergleichbare Schneckengetriebe mit zylindrischen Schnecken. Trotzdem ist ihr Einsatz bislang auf Sonderanwendungen beschränkt, da die Herstellung der globoiden Schnecken bislang aufwändig und teuer war. Das hier vorgestellte Verfahren bietet die Möglichkeit durch Umformung in kürzester Zeit globoide Schnecken in hoher Qualität herzustellen.Worm gears with globoidal snails have long been known in the literature. They are characterized by a higher load capacity and better efficiencies than comparable worm gears with cylindrical screws. Despite this, their use has so far been restricted to special applications, since the manufacture of the globoid snails used to be complex and expensive. The process presented here offers the possibility of producing high-quality globoide screws by forming in a very short time.

1 zeigt eine globoide Schnecke (1) in der Draufsicht zwischen zwei Walzen 2 und 3, die in der Form von schrägverzahnten Zahnrädern ausgeführt sind. 1 shows a globoide snail ( 1 ) in plan view between two rollers 2 and 3 , which are designed in the form of helical gears.

Die Formgebung der Zähne auf der globoiden Schnecke zeigt 2. Die beiden Walzen 2 und 3 drücken in Richtung 7 und 8 auf einen Rohling 1 aus dem die Schnecke entsteht. Durch die Bewegung von Walze 2 in Richtung 5 und die Bewegung von Walze 3 in Richtung 6 bei gleichzeitiger Drehung 4 der Schnecke 1 entsteht durch Umformung das Zahnprofil auf der Schnecke. Während der Umformung werden die Walzen 2 und 3 in Richtung 7 und 8 zugestellt, bis sie Ihre Endlage erreicht haben. Dabei muss die Bewegung der Walzen 2 und 3 in Richtung 5 und 6 exakt mit der Drehung der Schnecke 1 koordiniert werden.The shaping of the teeth on the globoidal snail shows 2 , The two rollers 2 and 3 push in direction 7 and 8th on a blank 1 from which the snail arises. By the movement of roller 2 in the direction 5 and the movement of roller 3 in the direction 6 with simultaneous rotation 4 the snail 1 The tooth profile on the screw is formed by forming. During forming, the rolls become 2 and 3 in the direction 7 and 8th delivered until they have reached their final position. It must be the movement of the rollers 2 and 3 in the direction 5 and 6 exactly with the rotation of the screw 1 be coordinated.
