Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine Zahnwellenverbindung zwischen einer Profilwelle und einer Nabe gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to a splined shaft connection between a profiled shaft and a hub according to the Preamble of claim 1.
Nach dem Stand der Technik ist bekannt, bei Zahnwellenprofilen mit Evolventenflanken bei 30° Eingriffswinkel die beiden zu fügenden Teile mit Profilen (d. h. Innen- und Außenprofil) derart herzustellen, dass beim Außenprofil das Wälzfräsverfahren und beim Innenprofil der Nabe das Stossen oder Räumen angewandt wird.To The prior art is known in splined shaft profiles with involute flanks at 30 ° pressure angle the two to be joined Parts with profiles (i.e., inner and outer profiles) in such a way produce that the outer profile Wälzfräsverfahren and applied to the inner profile of the hub pushing or clearing becomes.
Hierbei ist zu beachten, dass durch die Festlegung der Profilverbindung (Spiel-, Übergangs- oder Festsitz) die Genauigkeit der Fertigungstoleranzen der Profile eine wesentliche Rolle spielt. Die herkömmlichen Fertigungsverfahren weisen den Nachteil auf, dass an den Stirnseiten der Innen- und Außenprofile ein scharfkantiger Übergang entsteht, der unter Umständen in nachteiliger Weise zu Grat führen kann.in this connection It should be noted that by defining the profile connection (Play, transition or tight fit) the accuracy of Manufacturing tolerances of the profiles plays an essential role. The conventional manufacturing methods have the disadvantage on that on the front sides of the inner and outer profiles a sharp-edged transition arises, which may be can disadvantageously lead to burr.
Um die miteinander zu verbindenden Teile für die Montage vorzubereiten, ist daher mindestens noch ein Arbeitsgang vorzusehen, bei dem die Kanten entsprechend behandelt werden. Insbesondere für die Übergangs- und Festsitzvarianten ist meist ein aufwändiges Entgraten beiden Teile notwendig, um das „Anschnäbeln" in der Montage zu gewährleisten. Des weiteren kann bei der Montage der Fall auftreten, dass beim Fügevorgang aufgrund der scharfkantigen Profilstirnseiten vor allem bei ungehärteten Teilen Späne entstehen, was unerwünscht ist; hinzu kommt, dass man auch die Späne aufgrund von Unzugänglichkeiten nicht erkennen kann.Around to prepare the parts to be joined together for assembly Therefore, at least one additional operation should be foreseen in which the Edges are treated accordingly. Especially for the transition and fixed seat variants is usually a complex Deburr both parts necessary to "biting" to ensure in the assembly. Furthermore, at The mounting of the case occur during the joining process due to the sharp-edged profile end faces especially when uncured Sharp chips arise, which is undesirable; come in addition, that you also get the shavings due to inaccessibility can not recognize.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Zahnwellenverbindung zwischen einer Profilwelle und einer Nabe anzugeben, welche zum Einen montagefreundlich verfügbar ist und zum Anderen keine zusätzlichen Arbeitsgänge oder Werkzeuge erfordert.Of the present invention is based on the object, a spline connection between a profiled shaft and a hub, which is to One is easy to install and the other no additional operations or tools required.
Zudem soll durch die erfindungsgemäße Zahnwellenverbindung bei einer Reduzierung der Herstellungs- und Montagekosten die Prozesssicherheit erhöht und die Qualität verbessert werden.moreover is intended by the toothed shaft connection according to the invention with a reduction in manufacturing and assembly costs, process reliability increased and the quality improved.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.These The object is solved by the features of claim 1. Further embodiments and advantages of the invention are apparent from the dependent claims.
Demnach wird eine Zahnwellenverbindung zwischen einer Profilwelle und einer Nabe vorgeschlagen, bei der bei der Profilwelle mittels eines Wälzfräsers flankenseitig eine Einführungsphase gefertigt ist, welche durch eine spezielle Ansteuerung des Wälzfräsers über das CNC-Programm an der Maschine entsteht.Therefore is a spline connection between a profiled shaft and a Hub proposed in the case of the profile shaft by means of a hob flank side an introduction phase is made, which by a special control of the hob above the CNC program is created on the machine.
Hierbei ist nicht erforderlich, dass ein spezieller Fräser verwendet wird oder dass die Fertigungszeit erhöht wird.in this connection is not required to use a special cutter or that the production time is increased.
Gemäß der Erfindung sind die Einführungswinkel an den beiden Zahnflanken der Zähne der Profilwelle sehr flach und weisen eine geringe Länge auf. Des weiteren weist der Zahnkopf der Zähne der Profilwelle einen Einführungswinkel auf, welcher bereits beim Drehen mitgefertigt wird. Dadurch entsteht an der Stirnseite der Profilwelle eine Kontur, welche über den gesamten Bereich (Fuß- und Kopfdurchmesser und beidseitige Zahnflanken) kleiner ist, als die Kontur der Stirnseite des Innenprofils der Nabe.According to the Invention are the insertion angle on the two tooth flanks the teeth of the profile shaft are very flat and have a low Length up. Furthermore, the tooth head of the teeth the profile shaft on an insertion angle, which already while turning is mitgefertigt. This results in the front side the profile wave a contour, which over the entire range (Foot and head diameter and tooth flanks on both sides) is smaller than the contour of the end face of the inner profile of Hub.
Damit ist es möglich, die Nachbehandlung der Kanten an den Stirnseiten auf ein Minimum zu verringern, was beispielsweise über Bürsten erfolgen kann, oder sogar ganz auf eine Nachbehandlung zu verzichten, wenn die Fertigung der Profile technologisch so ausgelegt ist, dass ein Grat vermieden werden kann.In order to It is possible the aftertreatment of the edges on the front sides to a minimum, for example, about Brushing can be done, or even completely on an aftertreatment to waive if the production of the profiles technologically designed so is that a burr can be avoided.
Beim Fügen der beiden Teile bei der Montage ist damit gewährleistet, dass sich vor allem bei ausgelegten Übergangs- und Festsitzen die Teile sicher vorzentrieren, wodurch ein sauberer Fügevorgang ermöglicht wird.At the Joining of the two parts during assembly is thus ensured that especially with laid transition and fixed seats pre-center the parts safely, resulting in a cleaner joining process is possible.
Des weiteren entsteht der Vorteil, dass die Fügekräfte überschaubarer und stabiler sind, weil Schwankungen durch scharfe Kanten oder entstehende Späne vermieden werden. Damit ist ein insgesamt stabilerer Prozess gewähr leistet, der eine höhere Qualität zur Folge hat und Herstellungs- und Montagekosten verringert.Furthermore, there is the advantage that the joining forces are manageable and stable, because Fluctuations due to sharp edges or resulting chips are avoided. This ensures an overall more stable process, resulting in higher quality and reduced manufacturing and assembly costs.
