Die Vorteile kraftschlüssiger Welle-Nabe-Verbindun gen nutzend, sind inzwischen viele verschiedene Ausfüh rungen von Spannsätzen bekanntgeworden, die in der Mehrzahl aus zwischen Welle und Nabe angeordneten, nicht selbsthemmenden konischen Ringen bestehen, welche zur Herstellung von Kraftschluß mittels am Umfang angeordneter und mittels Drehmomentschlüssel betätigter Schrauben gegeneinander verspannt und zum Lösen durch Abdrückschrauben zurückgeholt werden.The advantages of a positive shaft-hub connection use, there are now many different designs of clamping sets, which are known in the A plurality of arranged between the shaft and the hub, are not self-locking conical rings, which for the production of adhesion by means of Scope arranged and using a torque wrench actuated screws clamped against each other and to Loosening can be brought back by forcing screws.
Auch sind bereits solche Vorrichtungen bekannt gewor den, bei denen die konischen Ringe zum Spannen durch eine zentral angeordnete und von Hand betätigte Mutter gegeneinander verschoben werden.Such devices have also become known the one where the conical rings are used for tensioning a centrally located and hand operated mother be moved against each other.
Da aber die Konen dieser Ringe oftmals nicht selbst hemmend sind, ist das übertragbare Drehmoment ent sprechend niedrig, wie auch eine Mutternsicherung unbedingt erforderlich ist. But since the cones of these rings are often not themselves are inhibiting, the transmissible torque is ent very low, like a nut lock is absolutely necessary.
Die Patentschrift DE 42 11 365 zeigt einen solchen Spannsatz zur lösbaren Klemmverbindung zwischen Welle und Nabe, bestehend aus zwei offenen selbsthemmenden konischen Ringen, die zum Spannen und Lösen der Klemm verbindung von Hand durch eine Normmutter gegenein ander 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 DE 42 11 365 shows such a Clamping set for releasable clamping connection between shaft and hub, consisting of two open self-locking conical rings used to tighten and loosen the clamp connection by hand using a standard nut others are shifted and in the end face about in the middle a sack-shaped chamber with an undercut into which the ring resting in the hub, which has a neck with a collar at its free end possesses, resiliently engages after axial pressure.
Die Aufgabe der Erfindung besteht nun darin, den oben beschriebenen Spannsatz gemäß den Merkmalen derart zu verbessern um einen mechanisch anzieh- und lösbaren Spannsatz zu schaffen, der hohe Drehmomente überträgt, einen guten Rundlauf zwischen Welle und Nabe gewähr leistet und keine Mutternsicherung benötigt. Dieses wird dadurch erreicht, daß die Konen durch ihre Steigung von 1 : 12 selbsthemmend sind und die Mutter durch einem aus Kegelradkranz und einem Steckritzel gebildeten Kraftverstärker von Hand oder mittels mechanischem Schrauber oder desgl. drehend betätigt wird.The object of the invention is now the above described clamping set according to the features improve by a mechanically tightenable and detachable Creating a clamping set that transmits high torques, ensure a good concentricity between shaft and hub achieves and does not require a nut lock. This is achieved in that the cones through their Slope of 1:12 are self-locking and the mother through a bevel gear ring and a pinion formed booster by hand or by means mechanical screwdriver or the like. rotating is operated.
Ferner dadurch, daß das Steckritzel an seiner Stirn seite einen zylindrischen Zapfen besitzt und mit diesem in der radialen Bohrung eines an der Mutter angelenkten Spreizrings drehbar geführt wird.Furthermore, in that the sprocket on his forehead side has a cylindrical pin and with this in the radial bore one on the nut articulated expansion ring is rotatably guided.
Außerdem dadurch, daß der Spreizring einen Stift, eine Schraube oder dergl. trägt, die in den Trenn schnitt des konischen Ringes eingreifen und den Spreizring verdrehsicher führen. In addition, in that the expansion ring has a pin, carries a screw or the like, which in the separator cut the conical ring and the Guide the expansion ring against twisting.
Des Weiteren dadurch, daß das Steckritzel an seiner Oberseite so ausgebildet ist, daß zu seiner Betätigung wahlweise das Einstecken der Klinge eines Handhebels, eines Drehmomentenschlüssels, eines mechanischen Schlagschraubers oder dergleichen gegeben ist.Furthermore, that the pinion on its Top is designed so that it is actuated optionally inserting the blade of a hand lever, a torque wrench, a mechanical one Impact wrench or the like is given.
Mit dem erfindungsgemäß ausgeführten Spannsatz, seinem Kegelradvorgelege und seiner flachen Kegelsteigung von 1 : 12 lassen sich bei der Verwendung eines mecha nischen Schlagschraubers sehr hohe Normaldrücke erzeugen bei guter Lösbarkeit des Spannsatzes, wobei eine Mutternsicherung wegen der sehr flachen Kegel steigung nicht erforderlich ist.With the inventive clamping set, his Bevel gear and its flat bevel pitch of 1:12 can be used when using a mecha African impact screwdriver very high normal pressures produce with good releasability of the clamping set, whereby a nut lock because of the very flat cone slope is not required.
Die Erfindung wird anhand der beigefügten Zeichnungen näher erläutert. Es zeigen:The invention will become apparent from the accompanying drawings explained in more detail. Show it:
