Description
"Vorrichtung zum Befestigen einer Klemmnabe auf einer Antriebswelle" "Device for attaching a clamping hub to a drive shaft"
Die Erfindung richtet sich auf eine Vorrichtung zum Befestigen einer Klemmnabe auf einer Antriebswelle, wobei ein äußerer Spannring mit innerer Konusfläche mittels diesen durchsetzender und in entsprechende Gewindebohrungen der Klemmnabe einschraubbarer, axial gerichteter Spannschrauben mit einer äußeren Konusfläche der Klemmnabe verspannbar ist. Klemmnabe und äußerer Spannring bilden eine Funktionseinheit. The invention is directed to a device for fastening a clamping hub to a drive shaft, whereby an outer clamping ring with an inner conical surface can be clamped to an outer conical surface of the clamping hub by means of axially directed clamping screws that pass through the clamping ring and can be screwed into corresponding threaded holes in the clamping hub. The clamping hub and outer clamping ring form a functional unit.
Bei bekannten Vorrichtungen dieser Art ist es erforderlich, zum Lösen einer derartigen Klemmnabe die Spannschrauben in axialer Richtung vollständig herauszuschrauben und dann mindestens teilweise in mit Innengewinde versehene sogenannte Abdrücklöcher im Spannring einzuschrauben, die dann mit ihren freien Enden gegen die Klemmnabe greifend den Spannring von letzterer wegdrücken. Dies erfordert einen entsprechenden größeren axialen Bauraum, der in vielen Anwendungsfällen kritisch ist, und zudem einen beträchtlich größeren Aufwand durch Ausbildung der vorerwähnten Abdrücklöcher im Spannring sowie entsprechend lange Montagebzw. Demontagezeiten für die sogenannte Umfunktion der Spannschrauben durch erst vollständiges axiales Ausbauen derselben und dann Wiedereinschrauben in die Abdrücklöcher.In known devices of this type, it is necessary to completely unscrew the clamping screws in the axial direction in order to loosen such a clamping hub and then screw them at least partially into so-called forcing holes in the clamping ring, which have an internal thread. The free ends of these then grip the clamping hub and press the clamping ring away from the latter. This requires a correspondingly larger axial installation space, which is critical in many applications, and also a considerably larger effort due to the formation of the aforementioned forcing holes in the clamping ring, as well as correspondingly long assembly and disassembly times for the so-called conversion of the clamping screws by first completely removing them axially and then screwing them back into the forcing holes.
Aufgabe der Erfindung ist die Schaffung einer Lösung, die in erster Linie einen geringeren axialen Bauraum benötigt und zudem fertigungsgünstig und bedienungsfreundlich ist.The object of the invention is to create a solution that primarily requires less axial installation space and is also inexpensive to manufacture and easy to use.
Bei einer Vorrichtung der eingangs bezeichneten Art wird diese Aufgabe gemäß der Erfindung dadurch gelöst, daß in zur Klemmnabe offenen, den Spannschrauben zugeordneten Ausnehmungen des Spannringes jeweils eine Hülse mit der zugeordneten Spannschraube entsprechendem Innengewinde angeordnet ist, die etwas kürzer als die zugeordnete Ausnehmung ist, derart, daß beim Herausschrauben einer Spannschraube die zugeordnete Gewindehülse, gegen eine Innenschulter der Ausnehmung greifend, gemeinsam mit dem Spannring von der Klemmnabe wegbewegbar ist.In a device of the type described at the outset, this object is achieved according to the invention in that in recesses of the clamping ring that are open to the clamping hub and associated with the clamping screws, a sleeve with an internal thread corresponding to the associated clamping screw is arranged, which is somewhat shorter than the associated recess, such that when a clamping screw is unscrewed, the associated threaded sleeve, gripping against an inner shoulder of the recess, can be moved away from the clamping hub together with the clamping ring.
Aufgrund dieser Ausgestaltung ist ersichtlich, daß beim Lösen der Klemmnabe von der Welle durch Lösen der Spannschrauben diese nur um ein geringes Maß in axialer Richtung herausgeschraubt werden müssen, um dennoch ein einwandfreies Lösen der zugeordneten Konusflächen von Klemmnabe und Spannring zu gewährleisten, insbesondere die sogenannte Umfunktion der Spannschrauben durch vollständiges Herausbewegen aus den Bohrungen in der Klemmnabe und im Spannring und nachfolgendes Wiedereinschrauben in gesonderte Abdrücklöcher im Spannring entfällt. Der demgegenüber erfor-Due to this design, it is clear that when the clamping hub is released from the shaft by loosening the clamping screws, these only need to be unscrewed a small amount in the axial direction in order to ensure that the associated conical surfaces of the clamping hub and clamping ring are released properly, in particular the so-called conversion of the clamping screws by completely moving them out of the holes in the clamping hub and clamping ring and then screwing them back in into separate forcing holes in the clamping ring is no longer necessary.
derliche Mehraufwand für die Ausbildung der Ausnehmungen im Spannring und die in diesen anzuordnenden Gewindehülsen ist von untergeordneter Bedeutung.The additional effort required to create the recesses in the clamping ring and the threaded sleeves to be arranged in them is of minor importance.
Die Erfindung ist nachstehend anhand der Zeichnung beispielsweise näher erläutert. Diese zeigt in:The invention is explained in more detail below using the drawing, for example. This shows:
Fig. 1 eine Vorrichtung gemäß der Erfindung im Schnitt, und zwar in der oberen Schnitthälfte im verspannten Zustand von Klemmnabe und Spannring und in der unteren Schnitthälfte im entspannten Zustand der Vorrichtung und inFig. 1 shows a device according to the invention in section, namely in the upper half of the section in the clamped state of the clamping hub and clamping ring and in the lower half of the section in the relaxed state of the device and in
Fig. 2 einen Spannringausschnitt der Vorrichtung mit in diesen eingesetzter Spannschraube und auf dieser fixierter Hülse im Montagezustand.Fig. 2 shows a clamping ring section of the device with the clamping screw inserted into it and the sleeve fixed on it in the assembled state.
Eine Klemmnabe 1 ist mit ringsum angeordneten Durchgangsbohrungen 2 zur Befestigung beispielsweise mit einer Wellenkupplung oder anderen anzutreibenden Teilen versehen. Die Klemmnabe 1 ist ferner mit einer üblichen Innenöffnung 3 zur Aufnahme eines nicht gezeigten Wellenendes ausgebildet, wobei an einem Ende der Klemmnabe 1 eine äußere Konusfläche 4 ausgebildet ist, die mit einer entsprechenden inneren Konusfläche 5 eines Spannringes 6 zusammenwirkt. Zwischen den Durchgangsbohrungen 2 und der InnenöffnungA clamping hub 1 is provided with through holes 2 arranged all around for fastening, for example, with a shaft coupling or other parts to be driven. The clamping hub 1 is also designed with a conventional inner opening 3 for receiving a shaft end (not shown), with an outer conical surface 4 being formed at one end of the clamping hub 1, which interacts with a corresponding inner conical surface 5 of a clamping ring 6. Between the through holes 2 and the inner opening
sind eine Anzahl von Gewindebohrungen 7 in der Klenunnabe ausgebildet und eine entsprechende Anzahl von glatten Bohrungen 8 im Spannring 6, deren der Klemmnabe 1 zugeordnete Enden sich zu Ausnehmungen 9 erweitern, in denen jeweils eine Hülse 10 mit Innengewinde angeordnet ist, welche mit Innenschultern 11 der Ausnehmungen 9 zusammenwirken, sobald Spannschrauben 12 aus der Spannstellung gemäß oberer Schnitthälfte der Zeichnung aus der Gewindebohrung 7 in der Klemmnabe 1 herausgeschraubt werden.a number of threaded holes 7 are formed in the clamping hub and a corresponding number of smooth holes 8 in the clamping ring 6, the ends of which are assigned to the clamping hub 1 and expand to form recesses 9, in each of which a sleeve 10 with an internal thread is arranged, which interact with internal shoulders 11 of the recesses 9 as soon as clamping screws 12 are unscrewed from the clamping position according to the upper half of the drawing from the threaded hole 7 in the clamping hub 1.
Um zu verhindern, daß sich die Gewindehülsen 10 beim Einschrauben der Spannschrauben 12 mit der gegenüberliegenden Fläche der Klemmnabe 1 verspannen, werden zweckmäßig die Gewindehülsen 10 mittels eines vorher auf die entsprechende Stelle der Gewinde der Spannschrauben oder des Innengewindes der Hülsen 10 aufgebrachten Klebers soweit auf der zugeordneten Spannschraube 12 fixiert bzw. geheftet, daß bei Anlage des Schraubenkopfes 13 am Spannring 6 ein Mindestabstand X (siehe Fig. 2) gewährleistet ist.In order to prevent the threaded sleeves 10 from clamping against the opposite surface of the clamping hub 1 when screwing in the clamping screws 12, the threaded sleeves 10 are expediently fixed or stapled onto the associated clamping screw 12 using an adhesive previously applied to the corresponding point on the threads of the clamping screws or the internal thread of the sleeves 10, so that a minimum distance X (see Fig. 2) is ensured when the screw head 13 is in contact with the clamping ring 6.
Die Montage des Spannringes 6 an der Klemmnabe erfolgt erst, wenn alle Spannschrauben 12 und Hülsen 10 vorher in der Stellung gemäß Fig. 2 festgelegt sind.The clamping ring 6 is only mounted on the clamping hub when all clamping screws 12 and sleeves 10 have been previously fixed in the position shown in Fig. 2.
Wie insbesondere die untere Schnitthälfte der Zeichnung verdeutlicht, wird beim Herausschrauben jeder SpannschraubeAs the lower half of the drawing shows, when unscrewing each clamping screw
12 aus der Gewindebohrung 7 der Klemmnabe 1 über die Hülse
10 und die Schulter 11 der Spannring 6 in axialer Richtung von der Klemmnabe 1 weggedrückt. Dabei versteht es sich,
daß sowohl beim Anziehen des Spannringes als auch beim Lösen desselben jede Spannschraube jeweils nur um einen geringen
Betrag gedreht wird, um dann kreisförmig fortschreitend die nächste Spannschraube zu betätigen, bis jeweils
eine feste Spannstellung bzw. ausreichende Freigabestellung erreicht ist.12 from the threaded hole 7 of the clamping hub 1 via the sleeve 10 and the shoulder 11 of the clamping ring 6 in the axial direction away from the clamping hub 1. It is understood that
that both when tightening the clamping ring and when loosening it, each clamping screw is only turned by a small amount and then the next clamping screw is actuated in a circular manner until a fixed clamping position or sufficient release position is reached.
