Description
Technisches GebietTechnical area
Die vorliegende Erfindung betrifft ein Verfahren zum Verbinden eines Drehelements mit einer Nabe. Verbindungen dieser Art werden insbesondere bei Kurbelwellenzapfen für die Anbringung von Torsionsschwingungsdämpfern oder von Riemenscheiben verwendet. Eine bisher eingesetzte Verbindung wird dadurch erreicht, dass die mit dem Kurbelwellenzapfen verbundene Nabe mit einem Bund versehen wird, an den die Scheibe des Torsionsschwingungsdämpfers oder der Riemenscheibe angeschraubt wird. Eine solche Lösung ist herstellungstechnisch und auch von der Montage her mit einem nicht zu vernachlässigenden Aufwand verbunden. Es besteht deshalb der Wunsch nach einer vereinfachten Lösung.The present invention relates to a method for connecting a rotary member to a hub. Compounds of this type are used in particular for crankshaft journals for the attachment of torsional vibration dampers or pulleys. A previously used connection is achieved in that the hub connected to the crankshaft journal is provided with a collar to which the disc of the torsional vibration damper or the pulley is screwed. Such a solution is manufacturing technology and also associated with the assembly forth with a not inconsiderable expense. There is therefore a desire for a simplified solution.
Aus der
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Verfahren und eine Konstruktion zu schaffen, die einfach in ihrem Aufbau ist, leicht hergestellt werden kann und die in der Lage ist, hohe Torsionsmomente zu übertragen und auch Axialkräfte aufzunehmen. Darüber hinaus soll die Verbindung möglichst einfach herstellbar sein.The invention is therefore an object of the invention to provide a method and construction that is simple in construction, can be easily manufactured and is able to transmit high torsional moments and also absorb axial forces. In addition, the connection should be as easy to produce.
Die Lösung der gestellten Aufgabe wird mit den Merkmalen des Anspruchs 1 erreicht. Die Unteransprüche 2 bis 5 stellen vorteilhafte Weiterbildungen des Erfindungsgegenstandes dar.The solution of the problem is achieved with the features of
Bei der Verbindung eines beliebigen Drehelements mit einer Nabe ist vorgesehen, dass die Nabe mit einer von ihrer Stirnfläche hervorstehenden, auf der Außenwand eine Sternform oder Polygonform aufweisende Anschlussbuchse versehen ist, auf welche das Drehelement aufgesetzt ist, wobei das Drehelement eine der Stern- oder Polygonform der Anschlussbuchse entsprechende Öffnung hat. Die Stern- oder Polygonform der Anschlussbuchse wird im Hinblick auf die aufzunehmenden dynamischen Torsionsmomente ausgewählt. Bevorzugt wird eine Polygonform der Anschlußbuchse eingesetzt, welche abwechselnd aus konkaven und konvexen Ringflächen gebildet ist.In the connection of any rotary member with a hub is provided that the hub is provided with a protruding from its face, on the outer wall of a star-shaped or polygonal shape having connector socket on which the rotary member is mounted, wherein the rotary member one of the star or polygon shape the connection socket has corresponding opening. The star or polygon shape of the jack is selected for the dynamic torsional moments to be picked up. Preferably, a polygonal shape of the connector is used, which is formed alternately of concave and convex annular surfaces.
Die Befestigung des Drehelements auf der Anschlußbuchse erfolgt durch einen Stauchvorgang. Hierfür ist der äußere Rand der Anschlußbuchse in axialer Richtung so ausgebildet, dass er über das auf die Anschlußbuchse aufgesetzte Drehelement hinaussteht und einem Stauchvorgang unterworfen werden kann, wodurch das Drehelement axial an der Nabe fixiert wird. Eine Unterstützung dieser Befestigung wird dadurch noch erreicht, dass die Anschlußbuchse noch radial an das Drehelement gepresst wird. Das einzusetzende Drehelement kann einen sehr unterschiedlichen Aufbau haben. Für die Verbindung an der Nabe ist es jedoch vorteilhaft, wenn der an der Nabe anliegende Teil des Drehelements flanschartig ausgebildet ist. Bei einem Drehelement, das beispielsweise als Riemenscheibe ausgebildet ist, kann eine Tellerscheibe eingesetzt werden mit einem entsprechenden Außenkranz. Die neue Ausgestaltung der Verbindung eines Drehelements mit einer Nabe läßt außerdem zu, dass die Nabe mit einem Axialring ausgestattet werden kann, welcher für die Befestigung von zusätzlichen Drehelementen dienen kann.The attachment of the rotary member on the socket is done by a compression process. For this purpose, the outer edge of the connector in the axial direction is formed so that it protrudes beyond the patch on the socket connector rotary member and can be subjected to a compression process, whereby the rotary member is axially fixed to the hub. A support of this attachment is achieved by the fact that the connector is still pressed radially to the rotary member. The rotary element to be used may have a very different structure. For the connection to the hub, however, it is advantageous if the voltage applied to the hub part of the rotary member is formed like a flange. In a rotary element, which is designed for example as a pulley, a disc can be used with a corresponding outer rim. The new design of the connection of a rotary member with a hub also allows that the hub can be equipped with an axial ring, which can serve for the attachment of additional rotary elements.
Die Herstellung der Verbindung ist auf verschiedene Art möglich. Günstig ist es wenn an der Stirnfläche der Nabe durch einen Umformvorgang eine Anschlußbuchse in Polygonform gebildet wird, auf die des Drehelement mit seiner im Stanz- oder Spanvorgang hergestellten Öffnung aufgesetzt und festgepresst wird. Um eine gewünschte Genauigkeit der Verbindung herzustellen, werden die konkaven Ringflächen der Anschlußbuchse durch Abdrehen der Außenwölbungen hergestellt. Schließlich ist es von Vorteil, wenn auch die innere Kontur der Anschlussbuchse durch Abdrehen hergestellt wird, um dadurch den gewünschten Aufweitungsvorgang sehr genau durchführen zu können.The preparation of the compound is possible in various ways. It is favorable if a connecting bushing in polygonal form is formed on the end face of the hub by a forming process, on which the rotary element is placed and pressed with its opening produced in the punching or clamping process. In order to produce a desired accuracy of the connection, the concave annular surfaces of the connector are made by twisting the outer bulges. Finally, it is advantageous if the inner contour of the connector is made by twisting to thereby perform the desired expansion process very accurately.
