Abstract
Description
Die Erfindung betrifft die Geometrie einer neuen technisch einstellbaren Profilart, die unrunde Innen- und/oder Außenkonturen für technische Anwendungen bei formschlüssigen Verbindungen präsentiert. Die erfundenen Profile besitzen, anders als die üblichen Profile wie übliche Keil- und Zahnprofile, immer mathematische Stetigkeit, so dass sie erhebliche Vorteile für die Herstellung und die Montage bei den technischen Anwendungen der Profile für Welle-Nabe-Verbindungen aufweisen.The Invention relates to the geometry of a new technically adjustable Profile type, the non-round inner and / or outer contours for technical Applications with positive locking Presented connections. The invented profiles, unlike the usual profiles, have the usual wedge shape. and tooth profiles, always mathematical continuity, making them significant Benefits for manufacture and assembly in technical applications the profiles for Shaft-hub-connections exhibit.
Funktionserklärungfunction explanation
Die in der Technik bereits lange bekannten Epitrochoiden und Polygonprofile sind auf Basis der normalen Trochoiden entwickelt worden, dadurch dass ein Rollkreis auf einem Grundkreis gleitungsfrei abrollt. Derartige Profile haben zwar stetige Konturen, sie haben aber bislang nur bei kleinen Periodizitäten (Anzahl der tragenden Flanken) für die Welle-Nabe-Verbindungen technische Anwendungen gefunden, da die Geometrie derartiger Profile gegenüber Exzentrizitätsänderungen bei größeren Periodizitäten sehr empfindlich ist. Das heißt, mit zunehmender Exzentrizität beginnt sich die Konturkurve zu überschneiden, bevor eine als mehrflankig für Welle-Nabe-Verbindung geeignete Kontur gebildet werden kann. Dieser Sachverhalt hat bislang zur Folge, dass die gebräuchlichen Epithrochoiden und die darauf basierenden üblichen Polygonprofile praktisch nur bei kleinen Periodizitäten (bis vier) für Welle-Nabe-Verbindungenen „sichere" Anwendungen gefunden haben. Auf der anderen Seite haben die herkömmlichen Keil- und Zahnprofile zwar die oben genannte Einschränkung der Polygonprofile nicht, sie weisen aber keine mathematisch stetigen Konturen auf, was bei technischen Anwendungen sehr unvorteilhaft ist. Das ist zum Beispiel bei den torsionsbelasteten Keil- und Zahnprofil-Welle-Nabe-Verbindungen der Fall, wobei infolge der Flankenzentrierung praktisch mehrfache Passungen vorliegen.The in the art long known epitrochoid and polygon profiles have been developed on the basis of the normal trochoid, by that a rolling circle unrolling on a base circle smoothly. such Although profiles have continuous contours, but they have so far only at low periodicities (Number of supporting flanks) for the shaft-hub connections technical applications found since the geometry of such profiles against eccentricity changes very much at larger periodicities is sensitive. This means, with increasing eccentricity begins to overlap the contour curve, before one as mehrflankig for Shaft-hub connection suitable contour can be formed. This The facts have so far been that the common epithrochoids and the usual based on it Polygon profiles practically only at small periodicities (to four) for Shaft-hub connections found "safe" applications to have. On the other hand, the conventional wedge and tooth profiles Although the above limitation not the polygonal profiles, but they have no mathematically continuous Contours on, which is very unfavorable in technical applications is. This is the case, for example, with the torsion-loaded wedge and tooth profile shaft-hub connections the case, where due to the edge centering practically multiple Passports available.
Der
Kerngedanke der hier dargelegten Erfindung liegt im Einbauen von
zusätzlichen
komplexen Exzentrizitäten
in die Geometrie des epitrochoidischen Profils, dahingehend dass
die oben erläuterten
Nachteile der herkömmlichen
formschlüssigen
Polygon-, Keil- und Zahnprofilverbindungen beseitigt werden.
Im Gegensatz zu den herkömmlichen Keil- und Zahnprofilen bieten die erfundenen Profile drei vorteilhafte für die technischen Anwendungen entscheidende Eigenschaften an:
- a) Zum einen sind die Konturen der Profile stetig. Diese Eigenschaft ermöglicht die gleichmäßige Zentrierung des Profils auf dem gesamten Profilumfang und nicht nur auf den tragenden Flanken.
- b) Darüber
hinaus sind die Krümmungen
an der Profilkontur (r1 und r2 gemäß
1 ) mit Hilfe von kombinierten und in der Profilgeometrie zusätzlich eingebauten Exzentrizitäten einstellbar. Diese Eigenschaft ermöglicht die Anpassung des Profils an zu erfüllende Funktionen sowie an die Belastung und an die Fertigungseinschränkungen. - c) Die dritte vorteilhafte Eigenschaft der erfundenen Profilgeometrie ist, dass die Anzahl der tragenden Profilflanken beliebig gewählt werden kann.
- a) On the one hand, the contours of the profiles are continuous. This feature allows for even centering of the profile over the entire profile circumference, not just on the supporting flanks.
- b) In addition, the curvatures on the profile contour (r 1 and r 2 according to
1 ) with the aid of combined eccentricities additionally installed in the profile geometry. This feature allows the profile to be matched to the functions to be performed, the load and the manufacturing constraints. - c) The third advantageous feature of the invented profile geometry is that the number of load-bearing profile edges can be chosen arbitrarily.
