Description

Elektrischer Einzelantrieb für Arbeitsmaschinen durch Riemen mit einer den Riemen spannenden Feder. Die Erfindung betrifft den elektrischen Einzelantrieb von Arbeitsmaschinen durch Riemen oder ähnlich wirkende Zugmittel, bei dem der Elektromotor unter der Wirkung einer den Riemen spannenden Feder steht. Es ist bereits ein Antrieb dieser Art bekannt, bei welchem die den Riemen spannende Feder zwischen dem in einem seitlich angebrachten Gelenke gelagerten Motor und einem Stützbolzen an einem gleichachsig mit dem Gelenke des Motors gelagerten einarmigen Hebel angeordnet ist, welcher mit einer ihn zwangläufig verstellenden Schraube zur Regelung der Federspannung verbunden ist. Diese Anordnung ergibt eine unzweckmäßige Bauart, da sie eine gekrümmte Anordnung der Spannfeder und des Federstützbolzens sowie eine das Gewicht des Motors ausgleichende zweite Feder und ferner eine besondere Ausbildung des Motors erfordert.Electric single drive for work machines by belt with one the spring tensioning the belt. The invention relates to the individual electric drive of work machines by belts or similarly acting traction devices, in which the electric motor is under the action of a spring tensioning the belt. It's already a drive known of this type, in which the belt tensioning spring between the in one laterally mounted joints mounted motor and a support bolt on an equiaxed is arranged with the joints of the motor mounted one-armed lever, which with connected to an inevitably adjusting screw for regulating the spring tension is. This arrangement results in an inconvenient design because it is a curved arrangement the tension spring and the spring support bolt as well as one that balances the weight of the motor second spring and also requires a special design of the motor.

Mit dieser bekannten Einrichtung hat der den Gegenstand der Erfindung bildende Antrieb die Lagerung des Motors in einem Gelenke und einen gleichachsig mit diesem Gelenke gelagerten, einen Federstützbolzen tragenden, mit einer-Regelungsschraube verbundenen Hebel gemeinsam, ist jedoch der Erfindung gemäß so ausgebildet, daß die erwähnten Nachteile vermieden werden.With this known device has the subject of the invention forming drive the bearing of the motor in one joint and one equiaxed with this joint mounted, a spring support bolt bearing, with a regulating screw connected lever together, but is designed according to the invention so that the disadvantages mentioned are avoided.

Das Neue besteht darin, daß das Gelenk des Motors so angeordnet ist, daß der Motor sich dauernd in oder in der Nähe seiner labilen Gleichgewichtslage befindet und der doppelarmig ausgebildete Federstützhebel an dem einen Arme eine seine Bewegung in einer Richtung begrenzende Anschlagschraube trägt. Die Erfindung -bietet außerdem den Vorteil, daß der doppelarmige Hebel; dessen Arme eine erheblich verschiedene Länge erhalten können, eine feinere Regelung der Federspannung gestattet.The novelty is that the joint of the motor is arranged in such a way that that the motor is constantly in or near its unstable equilibrium position is located and the double-armed spring support lever on to the one arm carries a stop screw limiting its movement in one direction. The invention also offers the advantage that the double-armed lever; whose arms can get a considerably different length, a finer regulation of the spring tension allowed.

Die Zeichnung stellt den Gegenstand der Erfindung in einem Ausführungsbeispiele dar, und zwar zeigt Abb. i den Elektromotor" mit Tragplatte und das Riemengetriebe in Seitenansicht, Abb. z einen Grundriß zu Abb. i ohne Elektromotor und Riemengetriebe.The drawing represents the subject matter of the invention in an exemplary embodiment Fig. i shows the electric motor "with support plate and the belt drive in side view, Fig. z is a plan for Fig. i without electric motor and belt drive.

Der Elektromotor a ist auf einer Tragplatte b befestigt, welche mittels des Zapfens c gegen das Maschinengestell d schwenkbar gelagert ist. Die Drehung des Elektromotors wird durch Riemen e und f auf die Maschine übertragen.The electric motor a is attached to a support plate b, which is mounted pivotably against the machine frame d by means of the pin c. The rotation of the electric motor is transmitted to the machine through belts e and f.

An dem Zapfen c ist zugleich ein Hebel g gelagert, der an einem Ende eine Anschlagschraube h trägt, welche seine Beweglichkeit gegen das Maschinengestell begrenzt. Am anderen Ende des Hebels g ist ein Bolzen i befestigt, welcher durch eine Öffnung in der Tragplatte b des Elektromotors hindurchgeführt ist. Am oberen Ende trägt der Bolzen i eine Mutter k, auf welche das eine Ende der Spannfeder L gestützt ist, deren anderes Ende an der Tragplatte b anliegt.At the same time a lever g is mounted on the pin c, which is at one end a stop screw h carries which its mobility against the machine frame limited. At the other end of the lever g a bolt i is attached, which through an opening in the support plate b of the electric motor is passed through. At the top At the end of the bolt i carries a nut k, on which one end of the tension spring L is supported, the other end of which rests against the support plate b.

Die Feder l spannt die Riemen und nimmt die Riemenschläge elastisch auf, so daß der Elektromotor und die Arbeitsmaschine geschont werden. Eine Änderung der Riemenspannung in weiteren Grenzen wird mit der Schraube h bewirkt.The spring l tensions the belt and takes the belt strokes elastically on, so that the electric motor and the work machine are spared. A change the belt tension within wider limits is effected with the screw h.
