Abstract

The tensioning set comprises a nut (3) which is turned by a bevel gear rim (4) and plug-in gear (5) for increasing turning power. The plug-in gear has a cylindrical plug (6) on its front side, and is rotatably guided in the radial bore (9) of the expanding ring (8). The expanding ring is joined to the nut, and carries a pin (15) which engages into the separating section of the conical ring and prevents the expanding ring from rotating.

Description

Die Erfindung betrifft einen Spannsatz zur lösbaren Spann­ verbindung zwischen Welle und Nabe, bestehend aus zwei aufgetrennten konischen Ringen, die zum Spannen und Lösen der Klemmverbindung durch eine Mutter gegeneinander ver­ schoben werden, wobei die Mutter durch einen aus Kegelrad­ kranz und Steckritzel gebildeten Kraftverstärker drehbar betätigt wird.The invention relates to a clamping set for releasable clamping connection between shaft and hub, consisting of two separated conical rings that are used for tensioning and loosening the clamp connection against each other by a nut be pushed with the nut through a bevel gear wreath and pinion formed power amplifier rotatable is operated.

Die Vorteile reibschlüssiger Welle-Nabe-Verbindungen nutzend, sind inzwischen viele verschiedene Ausführungen von Spannsätzen bekannt geworden, die in der Mehrzahl aus zwischen Welle und Nabe angeordneten konischen Ringen bestehen, welche zur Herstellung von Kraftschluß mittels am Umfang angeordneter Schrauben gegeneinander verspannt und zum Lösen durch Abdrückschrauben zurückgeholt werden.The advantages of friction-locked shaft-hub connections using, are now many different designs known from clamping sets, which in the majority conical rings arranged between shaft and hub exist which means for the production of adhesion clamped against each other on the circumference of the screws and can be retrieved by loosening the jacks.

Auch sind bereits solche Vorrichtungen bekannt geworden, bei denen die konischen Ringe zum Spannen durch eine zentral angeordnete Mutter gegeneinander verschoben werde. Da aber die Konen dieser Ringe wegen selbsttätiger Lösbar­ keit nicht selbsthemmend sind, ist das übertragbare Dreh­ moment entsprechend niedrig, wie auch eine Mutternsicherung unbedingt erforderlich ist. Such devices have also become known where the conical rings are clamped by a centrally located mother are moved against each other. However, since the cones of these rings can be loosened due to their automatic release transferability is not self-locking torque correspondingly low, as well as a nut lock is absolutely necessary.  

Die Patentschrift DE 42 11 365 C1 zeigt einen Spannsatz zur lösbaren Klemmverbindung zwischen Welle und Nabe, bestehend aus zwei offenen konischen Ringen, die zum Spannen und Lösen der Klemmverbindung durch eine Normmutter gegen­ einander verschoben werden und in deren Stirnseite etwa mittig eine sackförmige Kammer mit Hinterschnitt eingebracht ist, in die der in der Nabe ruhende Ring, welcher an seinem freien Ende einen Hals mit Bund besitzt, nach axialem Druck federnd einrastet.The patent specification DE 42 11 365 C1 shows a clamping set for releasable clamping connection between shaft and hub, consisting of two open conical rings for tensioning and loosen the clamp connection using a standard nut are shifted towards each other and in the front a sack-shaped chamber with an undercut is inserted in the middle into which the ring resting in the hub, which is on its free end has a neck with a collar, after axial pressure snaps into place.

Die Aufgabe der Erfindung besteht nun darin, den oben beschriebenen Spannsatz gemäß den Merkmalen derart zu verbessern und einen anzieh- und lösbaren Spannsatz zu schaffen, der hohe Drehmomente überträgt, einen guten Rund­ lauf zwischen Welle und Nabe gewährleistet und keine Mutternsicherung benötigt.The object of the invention is now the above described clamping set according to the features improve and a tightenable and detachable clamping set too create a good round that transmits high torques Guaranteed run between shaft and hub and none Nut lock required.

Dieses wird dadurch erreicht, daß die Mutter durch einen aus Kegelradkranz und einem Steckritzel gebildeten Kraft­ verstärker drehend betätigt wird.This is achieved in that the mother through a force formed from a bevel gear ring and a pinion amplifier is rotated.

Ferner dadurch, daß das Steckritzel an seiner Stirnseite einen zylindrischen Zapfen besitzt und mit diesem in der radialen Bohrung eines an der Mutter angelenkten Spreizrings drehbar geführt wird.Furthermore, in that the pinion on its end face has a cylindrical pin and with this in the radial bore of an expanding ring articulated on the nut is rotatably guided.

Außerdem dadurch, daß der Spreizring einen Stift, eine Schraube oder dergl. trägt, die in den Trennschnitt des konischen Ringes eingreifen und den Spreizring verdrehsicher führen.In addition, that the expansion ring a pin, a Screw or the like., Which in the cut of the engage conical ring and the expansion ring against rotation to lead.

Des weiteren dadurch, daß das Steckritzel an seiner Oberseite so ausgebildet ist, daß zu seiner Betätigung wahlweise das Einstecken der Nuß eines Handhebels, eines Drehmomenten- Schlüssels, eines mechanischen Schraubers oder dergleichen möglich ist. Furthermore, in that the sprocket on its top is designed so that optionally for its operation Inserting the nut of a hand lever, a torque Key, a mechanical screwdriver or the like is possible.  

Letztlich dadurch, daß trotz unterschiedlicher Gewinde- und Mutterngrößen das gleiche Steckritzel in einem weiten Wellendurchmesser-Bereich verwendbar ist.Ultimately by the fact that despite different thread and nut sizes the same sprocket in a wide range Shaft diameter range can be used.

Mit dem erfindungsgemäß ausgeführten Spannsatz mit seinem Kegelradvorgelege und seiner flachen Gewindesteigung, sowie seinen Konen mit der Steigung 1 : 12 lassen sich bei der Verwendung eines mechanischen Schraubers sehr hohe Normaldrücke erzeugen bei guter Lösbarkeit des Spannsatzes, wobei eine Mutternsicherung wegen der flachen Kegel­ steigung nicht erforderlich ist.With the inventive clamping set with his Bevel gear and its flat thread pitch, as well as its cones with a gradient of 1:12 very high using a mechanical screwdriver Generate normal pressures with good releasability of the clamping set, taking a nut lock because of the flat cone slope is not required.

Die Erfindung wird anhand der beigefügten Zeichnung näher erläutert. Es zeigt:The invention will become more apparent from the attached drawing explained. It shows:

Fig. 1 den Querschnitt des erfindungsgemäßen Spannsatzes zwischen Welle und Nabe eines Maschinenelementes. Fig. 1 shows the cross section of the clamping set according to the invention between the shaft and hub of a machine element.

Wird bei dem in der Figur dargestellten Spannsatz die Mutter 3 über den auf ihr befestigten und mit Paßstift 14 gesicherten Kegelradkranz 4 mittels Steckritzel 5 spannend bewegt, so verbleibt der auf der Welle 16 ruhende Ring in seiner Position, während der Ring 2 mit Spannteil 17 auf dem Ring 1 soweit verschoben wird, bis der gewünschte Reibschluß zwischen Welle 16 und Nabe 2 hergestellt ist.If, in the clamping set shown in the figure, the nut 3 is moved in an exciting manner by means of pinion 5 via the bevel gear ring 4 secured to it and secured with dowel pin 14 , the ring resting on the shaft 16 remains in its position, while the ring 2 with the clamping part 17 remains open the ring 1 is shifted until the desired frictional connection between shaft 16 and hub 2 is established.

Wird das Steckritzel 5 in entgegengerichteter Drehrichtung betätigt, so löst sich der Reibschluß zwischen Welle 16 und Nabe 17 infolge der Kupplung von Ring 2 über die Bunde 10 und 11 mit der Mutter 3 sofort wieder. If the pinion 5 is actuated in the opposite direction of rotation, the frictional engagement between shaft 16 and hub 17 is released immediately as a result of the coupling of ring 2 via collars 10 and 11 with nut 3 .

Der mit der Mutter 3 über die Bunde 12 und 13 gekuppelte Spreizring 8 dient dazu, den Zapfen 6 des Steckritzels 5 drehbar zu führen, während der Spreizring 8 seinerseits über den Stift 15 in dem Trennschnitt 18 des konischen Ringes 1 verdrehsicher geführt wird.The spreading ring 8 coupled with the nut 3 via the collars 12 and 13 is used to rotatably guide the pin 6 of the pinion 5 , while the spreading ring 8 in turn is guided against rotation via the pin 15 in the separating cut 18 of the conical ring 1 .

Um das Einstecken des Steckritzels 5 am ganzen Umfang des Spannsatzes zu gewährleisten, ist der Spreizring 8 mit am Umfang verteilten Radialbohrungen 9 versehen.In order to ensure that the pinion 5 is inserted over the entire circumference of the clamping set, the expansion ring 8 is provided with radial bores 9 distributed over the circumference.
