Gebiet der ErfindungField of the invention
Die Erfindung betrifft eine Kreiskeil-Verbindung für die Montage eines Zapfens oder dergleichen in einer zugeordneten Aufnahmeöffnung einer Maschinenstruktur, wobei der Zapfen oder dergleichen ein äußeres Kreiskeilprofil aufweist, welches mit einem der Aufnahmeöffnung zugeordneten komplementären inneren Kreiskeilprofil zusammenwirkt.The The invention relates to a circular wedge connection for assembly a pin or the like in an associated receiving opening a machine structure, wherein the pin or the like an outer Has circular wedge profile, which with one of the receiving opening associated complementary inner circular spline cooperates.
Hintergrund der ErfindungBackground of the invention
Kreiskeil-Verbindungen gehören zu den reibschlüssigen Verbindungen. Zur Montage werden die mit einem geringen Spiel zueinander ausgebildeten inneren bzw. äußeren Kreiskeilprofile kraftlos ineinander gefügt und sodann in einer solchen Drehrichtung gegeneinander verdreht, bei der sich die Kreiskeilprofile mit zunehmender Anpresskraft aneinanderlegen. Durch Verdrehen der beiden Kreiskeilprofile in der Gegenrichtung kann die Verbindung wieder gelöst werden. Die Steigung der Kreiskeile kann so gewählt werden, dass die Verbindung selbsthemmend ist, so dass Drehmomente in beiden Drehrichtungen übertragen werden können. Außerdem können axiale Kräfte übertragen wer den.Circular spline connections belong to the frictional connections. to Montage are designed with a small play each other inner or outer circular splines into each other without power joined and then in such a direction of rotation against each other twisted, in which the circular wedge profiles with increasing contact pressure another place. By turning the two circular splines in the opposite direction, the connection can be solved again. The slope of the circular wedges can be chosen so that The connection is self-locking, allowing torques in both Turning directions can be transmitted. Furthermore can transmit axial forces who the.
Kreiskeil-Verbindungen werden zunehmend als Ersatz für herkömmliche Pressverbindungen, Schraubverbindungen oder dergleichen eingesetzt.Circular spline connections are increasingly being used as a replacement for conventional press connections, screw connections or the like used.
Aus
der
Aufgabe der ErfindungObject of the invention
Ausgehend von den dargelegten Nachteilen des bekannten Standes der Technik liegt der Erfindung deshalb die Aufgabe zu Grunde, eine Kreiskeil-Verbindung der im Oberbegriff des Anspruchs 1 genannten Art zu schaffen, die von der Materialpaarung von Zapfen einerseits und Maschinenstruktur andererseits weitgehend unabhängig verwirklicht werden kann, und die insbesondere bei einer Maschinenstruktur mit komplizierter Form eine einfachere Fertigung ermöglicht.outgoing from the stated disadvantages of the known prior art Therefore, the invention is based on the object, a circular wedge connection the type mentioned in the preamble of claim 1, which on the material pairing of pins on the one hand and machine structure on the other can be implemented largely independently, and the especially in a machine structure with a complicated shape allows for easier production.
Beschreibung der ErfindungDescription of the invention
Der Erfindung liegt die Erkenntnis zugrunde, dass durch eine Verlagerung des inneren Kreiskeilprofils von der Aufnahmeöffnung der Maschinenstruktur hin zu einem fertigungstechnisch einfach herstellbaren Zwischenelement das Material der Maschinenstruktur einerseits und deren für ein Einspannen in eine Präzisi onsbearbeitungsmaschine gegebenenfalls ungünstige Form nicht mehr relevant sind.Of the Invention is based on the finding that by a shift of the inner circular spline of the receiving opening of Machine structure towards a manufacturing technology easy to produce Intermediate element, the material of the machine structure on the one hand and their for clamping in a precision processing machine possibly unfavorable form are no longer relevant.
Die Erfindung geht daher aus von einer Kreiskeil-Verbindung für die Montage eines Zapfens oder dergleichen in einer zugeordneten Aufnahmeöffnung einer Maschinenstruktur, wobei der Zapfen oder dergleichen ein äußeres Kreiskeilprofil aufweist, welches mit einem der Aufnahmeöffnung zugeordneten komplementären inneren Kreiskeilprofil zusammenwirkt. Dabei ist erfindungsgemäß ein in eine kreisförmige Aufnahmeöffnung der Maschinenstruktur einsetzbarer Zwischenring vorgesehen, an dessen Innenumfang das innere Kreiskeilprofil ausgebildet ist.The Invention is therefore based on a circular wedge connection for the assembly of a pin or the like in an associated Receiving opening of a machine structure, wherein the pin or The like has an outer circular spline, which with a complementary associated with the receiving opening inner circular spline cooperates. It is according to the invention a in a circular receiving opening of the machine structure usable intermediate ring provided on the inner circumference of the inner circular spline is formed.
Der Zwischenring kann grundsätzlich auf jede geeignete Weise in der Aufnahmeöffnung befestigt sein. Gemäß einer bevorzugten Ausgestaltung der Erfindung ist jedoch vorgesehen, dass der Zwischenring mit Presssitz in die Aufnahmeöffnung eingesetzt wird, wozu diese entsprechend ausgebildet sind. Bei der Montage der Kreiskeil-Verbindung, d. h. beim zunehmenden Verdrehen des Zapfens gegenüber dem Zwischenring, wird dieser elastisch aufgeweitet und zunehmend an den Innenumfang der Aufnahmeöffnung angedrückt, womit die Reibschlusskraft des Zapfens in dem Zwischenring einerseits und des Zwischenringes in der Aufnahmeöffnung andererseits stetig vergrößert wird.Of the Intermediate ring can basically in any suitable way be secured in the receiving opening. According to one preferred embodiment of the invention, however, is provided that the intermediate ring with press fit inserted into the receiving opening what they are trained accordingly. During installation the circular wedge connection, d. H. with increasing twisting of the pin opposite the intermediate ring, this is elastically expanded and increasingly pressed against the inner circumference of the receiving opening, whereby the frictional engagement force of the pin in the intermediate ring on the one hand and the intermediate ring in the receiving opening on the other is steadily increased.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Kreiskeilprofile des Zapfens einerseits und des Zwischenringes andererseits in an sich bekannter Weise jeweils die Form einer logarithmischen Spirale haben. Die logarithmische Spirale hat die Eigenschaft, dass ihre Steigung konstant ist, d. h. das innere Kreiskeilprofil liegt bei jedem Verdrehwinkel vollflächig am äußeren Kreiskeilprofil an, so dass der Zwischenring im wesentlichen auf seinem gesamten Umfang gleichmäßig gedehnt und an die Innenumfangsfläche der Aufnahmeöffnung angelegt wird, womit ein homogener Presssitz des Zwischenringes in der Aufnahmeöffnung erreicht wird.In Another embodiment of the invention provides that the circular wedge profiles the pin on the one hand and the intermediate ring on the other hand in itself known manner each have the form of a logarithmic spiral. The logarithmic spiral has the property that its slope is constant, d. H. The inner circular spline is located at each angle of rotation full surface on the outer circular spline on, so that the intermediate ring substantially on its entire Circumference evenly stretched and to the inner peripheral surface the receiving opening is created, creating a homogeneous Press fit of the intermediate ring reached in the receiving opening becomes.
In weiterer bevorzugter Ausgestaltung der Erfindung weisen die Kreiskeilprofile des Zapfens bzw. des Zwischenringes jeweils drei im Winkelabstand von 120° zueinander beabstandete Kreiskeile auf, womit beim Spannen der Kreiskeil-Verbindung gleichzeitig eine exakte Zentrierung des Zapfens in dem Zwischenring gewährleistet wird.In a further preferred embodiment of the invention, the circular splines of the pin or the intermediate ring in each case three in Winkelabst and from 120 ° spaced circular wedges, which at the same time an exact centering of the pin is ensured in the intermediate ring during clamping of the circular wedge connection.
Gemäß einer letzten Ausführungsform der Erfindung ist der Zapfen außerhalb des Bereiches der Kreiskeile zylindrisch ausgebildet und dort drehfest mit dem Innenring eines Wälzlagers einer Kurvenlaufrolle oder einer Zapfenlaufrolle eines Riementriebes verbunden.According to one Last embodiment of the invention, the pin is outside the area of the circular wedges cylindrical and rotatably there with the inner ring of a rolling bearing of a cam roller or a pin roller of a belt drive connected.
