Description
Stand der TechnikState of the art
Die Erfindung betrifft eine Wellenkupplung für motorische Antriebe der im Oberbegriff des Anspruchs 1 definierten Gattung.The invention relates to a shaft coupling for motor Drives of the type defined in the preamble of claim 1.
Solche Wellenkupplungen finden beispielsweise Anwendung in Elektrohandwerkzeugmaschinen, wie Schrauber, Bohrer und dgl.Such shaft couplings can be found, for example Use in electric hand machine tools, such as screwdrivers, drills and the like
Bei einem bekannten Akkuschrauber
mit einer Wellenkupplung dieser Art (
Wellenkupplungen, deren Kupplungsteile
mit gegeneinander verdrehbaren Kupplungsklauen versehen sind, sind
z. B. aus der Druckschriften
Der Erfindung liegt daher die Aufgabe zugrunde, eine Wellenkupplung für motorische Antriebe anzugeben, bei der zwischen einem ersten und einem zweiten Kupplungsteil eine die Relativbewegung der beiden Kupplungsteile zueinander bremsende Dämpfungsvorrichtung angeordnet ist, welche fertigungstechnisch möglichst einfach zu realisieren ist.The invention is therefore the object based on a shaft coupling for to specify motor drives in which between a first and a second coupling part a the relative movement of the two Coupling parts arranged mutually braking damping device is which is technically as simple to implement as possible.
Vorteile der ErfindungAdvantages of invention
Die erfindungsgemäße Wellenkupplung mit den kennzeichnenden Merkmalen des Anspruchs 1 hat den Vorteil, dass durch die bei Relativbewegung zwischen den Kupplungsteilen wirksame Dämpfungsvorrichtung das Wechselspiel der Kupplungsteile gebremst erfolgt. Die Dämpfungsvorrichtung kann dabei so ausgelegt werden, dass ihr Dämpfungsmoment konstant oder direkt proportional der Winkelgeschwindigkeitsdifferenz der beiden Kupplungsteile ist. Damit wird einerseits bei kleinem Lastwechsel, also kleinem Drehmomentunterschied zwischen den Kupplungsteilen, ein Umschlagen der miteinander in Berührung stehenden Anlageflächen an den Kupplungsklauen verhindert und andererseits der Schlag bei größerem Drehmomentunterschied durch Energieumwandlung gedämpft. Dadurch werden die bisher auftretenden störenden Betriebsgeräusche unterdrückt und das Qualitätsgefühl für die mit der erfindungsgemäßen Kupplung ausgestattete Elektrohandwerkzeugmaschine, die nur geringe Geräusche, keine Vibration und keinen sog. Lottereffekt durch Wechselspiel zeigt, deutlich erhöht. Die Kupplungsteile werden durch die nur noch geringe Zahl der auftretenden Stöße und Schläge, die zudem noch gedämpft, also weniger hart erfolgen, weniger beansprucht, wodurch sich die Standzeit der Kupplung erhöht.The shaft coupling according to the invention with the characteristic Features of claim 1 has the advantage that by the relative movement between the coupling parts effective damping device the interplay of the coupling parts is slowed down. The damping device can be designed so that their damping torque is constant or directly proportional to the angular velocity difference between the two Coupling parts is. On the one hand, with a small load change, so small torque difference between the coupling parts, a reversal of the contacting contact surfaces on the Coupling claws prevented and, on the other hand, the blow caused by a larger torque difference Energy conversion dampened. As a result, the disturbing operating noises that have previously occurred are suppressed and the feeling for quality with the clutch according to the invention Equipped electric hand machine tool that makes little noise, no Shows vibration and no so-called lottery effect through interplay, clearly increased. The coupling parts are due to the small number of occurring Bumps and blows that also steamed So less hard, less stressed, which makes the Service life of the clutch increased.
Die erfindungsgemäß lediglich aus einem zwischen den Kupplungsteilen eingefügtem Federdraht bestehenden Dämpfungsmittel sind fertigungstechnisch sehr einfach zu realisieren.According to the invention only from one between the coupling parts inserted Spring wire existing damping means are technically very easy to implement.
Durch die in den weiteren Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Wellenkupplung möglich.By the measures listed in the other claims are advantageous developments and improvements in the claim 1 specified shaft coupling possible.
Vorteilhafterweise besteht das Reibelement aus mindestens zwei Federdrähten, die jeweils die Schenkel eines U-förmigen Federbügels bilden, wobei die beiden Bügelschenkel in Axialschlitzen oder -nuten, die in der koaxialen Fläche des einen Kupplungsteils ausgebildet sind, in Drehrichtung unverschieblich einlegen und sich an die koaxiale Fläche des anderen Kupplungsteils anliegen. Die beiden Axialschlitze zur Aufnahme der Bügelschenkel eines Federbügels können dabei diametral oder sekantal in der koaxialen Fläche angeordnet sein. Durch diese konstruktive Gestaltung ist der Fertigungsaufwand für die Dämpfungsvorrichtung extrem gering. Der Materialaufwand beschränkt sich auf einen U-förmigen Federbügel und Aufnahmenuten in dem einen Kupplungsteil, in die der Federbügel einfach eingelegt wird, und die Montagekosten sind durch reduzierten Montageaufwand gering.Advantageously, the friction element consists of at least two spring wires, each of which forms the legs of a U-shaped spring clip, the two clip legs in axial slots or grooves, which are formed in the coaxial surface of the one coupling part, insert immovably in the direction of rotation and adhere to the coaxial Fit the surface of the other coupling part. The two Axial slots for receiving the stirrup legs of a spring clip can be arranged diametrically or secantally in the coaxial surface. This constructive design means that the manufacturing effort for the damping device is extremely low. The material expenditure is limited to a U-shaped spring clip and receiving grooves in the one coupling part, into which the spring clip is simply inserted, and the installation costs are low due to the reduced installation effort.
