Description
Stand der TechnikState of the art
Die
Erfindung geht aus von einem Verfahren zur Befestigung einer Hülse auf
einer Welle, insbesondere zur Befestigung je einer Hülse auf
der Eingangswelle und der Ausgangswelle eines Drehmomentsensors,
nach der Gattung des unabhängigen Anspruchs.
Ein derartiges Verfahren ist aus der

der
Offenbarung der ErfindungDisclosure of the invention
Das erfindungsgemäße Verfahren mit den Merkmalen des unabhängigen Anspruchs hat gegenüber dem geschilderten Stand der Technik den Vorteil, dass durch die Ausbildung einer Prägung als Teil einer negativen Kontur an der Welle die Möglichkeit geschaffen wird, die Hülse vor der endgültigen Befestigung auf der Welle noch zu verschieben und exakt zu justieren, bevor der zugehörige Abschnitt der Hülse in die Kontur eingepresst wird. Vorzugsweise ist hierbei die Prägung in einer umlaufenden Einpressnut in der Welle angebracht, so dass einerseits die Grundform der Kontur mit einem Standard-Drehverfahren hergestellt werden kann und die anschließende Prägung, vorzugsweise als zahnförmige Rändelung, in der Nut erfolgt. Das beim Prägen nach außen verdrängte Material ragt dabei nicht über die Oberfläche der Welle hinaus, so dass die Hülse auf der Welle bis zur abschließenden Einpressung in die Kontur verschiebbar und justierbar bleibt. Wenn hierbei der Einpressvorgang bis zum Boden der Kontur erfolgt, so wird die vorzugsweise zahnförmige Prägung zweckmäßigerweise am Boden der Kontur angebracht. Ein vorteilhafte Alternative bei der Ausgestaltung der Kontur besteht darin, als negative Kontur eine Nut vorzusehen, welche sich nach außen erweitert und im Bereich der abgeschrägten oder nach außen gekrümmten Ränder eine vorzugsweise zahnförmige Prägung aufweist, wodurch die notwendige Einpresstiefe der Hülse in die Kontur verringert werden kann. Das Einpressen der Hülse erfolgt hierbei zweckmäßigerweise durch eine plastische Verformung durch Rollen oder durch Eindrücken mit einem oder mehreren StempelnThe inventive method with the characteristics of the independent Claim has opposite The described prior art has the advantage that by the Training an imprint created as part of a negative contour on the shaft the possibility will, the sleeve before the final Still to move the attachment on the shaft and to adjust it exactly before the associated one Section of the sleeve is pressed into the contour. Preferably, in this case, the embossing in a circumferential grooved groove mounted in the shaft, so that on the one hand the basic shape of the contour is made using a standard turning process can be and the subsequent embossing, preferably as a tooth-shaped knurling done in the groove. The embossing outwardly displaced material does not protrude over it the surface out of the shaft, leaving the sleeve on the wave until the final Pressing into the contour remains displaceable and remains adjustable. If In this case, the pressing in to the bottom of the contour takes place, so is the preferably tooth-shaped Embossing expediently attached to the bottom of the contour. An advantageous alternative the configuration of the contour is a negative contour Provide groove, which expands outward and in the area the beveled or to the outside curved margins a preferably tooth-shaped embossing having, whereby the necessary Einpresstiefe of the sleeve in the Contour can be reduced. The pressing of the sleeve takes place this expediently by a plastic deformation by rolling or by pressing with one or more stamps
Insbesondere bei einer Ausgestaltung der Welle als Hohlwelle, wie sie bei einem Drehmomentsensor mit einem Torsionselement zwischen zwei Wellenstümpfen verwendet wird, hat es sich als zweckmäßig erwiesen, wenn die Kontur zum Einpressen der Hülse in einen auf der Welle angebrachten Wulst eingeformt wird. Hierdurch wird sichergestellt, dass eine ausreichende Wandstärke für die negative Kontur zur Verfügung steht, ohne dass die Festigkeit der Welle in diesem Bereich geschwächt wird.Especially in an embodiment of the shaft as a hollow shaft, as in a Torque sensor used with a torsion element between two stub shafts it has proven to be appropriate when the contour for pressing the sleeve into one on the shaft attached bead is formed. This will ensure that a sufficient wall thickness for the negative contour available stands without weakening the strength of the shaft in this area.
