Description

Motorgetriebene Seil- und Kabelaufzugs-und -abzugsvorrichtung Die Erfindung betrifft eine motorgetriebene Seil-und Kabelaufzugs- und -abzugsvorrichtung.Motorized rope and cable hoist and haul-off device Die The invention relates to a motor-driven rope and cable pull-up and pull-off device.

Derartige Vorrichtungen wurden bisher von einem Motor oder einer Spiralfeder über ein Getriebe betätigt. Such devices were heretofore of a motor or a Coil spring operated via a gear.

Mittels eines Federmotors angetriebene Haspeln haben den Nachteil, daß die Umfangskraft proportional mit der aufgespulten Kabellänge abnimmt, sie erlauben daher nur eine sehr begrenzte Kabellänge aufzuwickeln. Beim Abspulen ergibt sich die entgegengesetzte Wirkung; je mehr von der Haspel an Kabellänge abgezogen wird, um so größer wird die Umfangskraft und steigt mitunter auf einen für die Zerreißfestigkeit des Kabels unzulässigen Wert an. Reels driven by a spring motor have the disadvantage that the circumferential force decreases proportionally with the coiled cable length, they allow therefore only wind up a very limited length of cable. When unwinding results the opposite effect; the more cable length is withdrawn from the reel, the greater the circumferential force and sometimes increases to one for the tensile strength of the cable.

Motorwinden üblicher Bauart erfordern einen größeren technischen Aufwand, um ein genügend elastisches Arbeiten bei gleichbleibendem Drehmoment zu ermöglichen. Motor winches of the usual type require a larger technical one Effort in order to work sufficiently elastic with constant torque enable.

Die Erfindung hat sich die Aufgabe gestellt, eine motorgetriebene Kabelaufzugs- und -abzugsvorrichtung mit einfacher Bau- und Arbeitsweise zu schaffen, die theoretisch unbegrenzte Kabellängen mit gleichbleibendem Drehmoment verarbeitet und bei Überschreitung dieses Drehmomentes das Kabel beliebig schnell von der Haspel abzuziehen gestattet.The invention has the task of providing a motor-driven To create cable hoisting and pulling devices with a simple construction and working method, which processes theoretically unlimited cable lengths with a constant torque and if this torque is exceeded, the cable can be removed from the reel at any time may be deducted.

Nach der Erfindung wird dies dadurch erreicht, daß das mit einer Kabeltrommel verbundene Motorgehäuse um seine Achse drehbar gelagert ist und daß walilweise das Gehäuse oder die Antriebswelle mit einer einen Schlupf erzeugende Bremse verbunden ist. Hierbei wird das physikalische Gesetz ausgenutzt, daß jede Kraftwirkung eine gleich große entgegengesetzt gerichtete Kraftwirkung erzeugt. According to the invention this is achieved in that the with a Cable drum connected motor housing is rotatably mounted about its axis and that Walilweise the housing or the drive shaft with a slip generating Brake is connected. Here the physical law is used that each Force effect produces an equally large oppositely directed force effect.

Die einen Schlupf erzeugende Bremse kann aus einem Windflügel- oder Wasserrad bestehen, während eine stufenlose Schlupfregelung mittels eines Verstellpropellers od. dgl. bewirkt werden kann. The brake producing a slip can consist of a wind vane or Water wheel exist, while a stepless slip control by means of a controllable pitch propeller or the like. Can be effected.

Die Vorrichtung nach der Erfindung kann vorteilhaft zum Aufwickeln des Kabels eines elektrischen Rasenmähers verwendet werden. The device according to the invention can advantageously be used for winding of the cord of an electric lawnmower.

Werden entsprechend der Erfindung sowohl das Motorgehäuse mit der Magnetwicklung eines Elektromotors als auch der Anker mit der Motorwelle drehbar gelagert und das Motorgehäuse mit einer Kabeltrommel versehen, während die Motorwelle eine einen Schlupf erzeugende Bremse, z. B. Windflügel, erhält, so drehen sich beide Teile des Motors entgegengesetzt, und zwar mit verschiedenem, durch die Größe des Schlupfes bedingtem Drehmoment. Je nach der Größe des Schlupfes wird ein entsprechender Teil der von der Motorwelle abgegebenen Gesamtleistung des Motors für die Drehung des Motorgehäuses abgezweigt. Are according to the invention both the motor housing with the Magnetic winding of an electric motor and the armature rotatable with the motor shaft stored and the motor housing provided with a cable drum, while the motor shaft a brake generating a slip, e.g. B. Wind blade receives, so both rotate Parts of the engine opposite, and with different, by the size of the Torque due to slip. Depending on the size of the slip, there will be a corresponding one Part of the total power output by the motor for rotation by the motor shaft branched off of the motor housing.

Die elastische Arbeitsweise der Vorrichtung nach der Erfindung läßt ohne weiteres ein Abziehen des aufgehaspelten Kabels bei eingeschaltetem Motor zu, sofern die ausgeübte Zugkraft das Motordrehmoment übersteigt. The elastic operation of the device according to the invention can easily pulling off the reeled cable closed with the engine switched on, provided that the tensile force exerted exceeds the engine torque.

In der Zeichnung ist als Ausführungsbeispiel der Erfindung ein elektrischer Rasenmäher mit selbsttätig sich aufwickelndem Anschlußkabel dargestellt. In the drawing, as an embodiment of the invention, an electrical Lawn mower shown with an automatically winding connection cable.

Auf dem fahrbaren Rahmen 1 des Rasenmähers ist ein Elektromotor derart aufgebaut, daß sein Gehäuse 2 oben und unten in Kugellagern 3 und 4 rotierbar gelagert ist. Das untere EQugellager 3 ist am Rahmen 1, das obere Kugellager 4 an einem Bügel 5 befestigt. On the mobile frame 1 of the lawn mower, an electric motor is such constructed that its housing 2 is rotatably mounted in ball bearings 3 and 4 above and below is. The lower E ball bearing 3 is on the frame 1, the upper ball bearing 4 on a bracket 5 attached.

Das Motorgehäuse 2 ist mit einer Kabeltrommel 6 versehen. Am unteren Ende der Motorwelle 7 ist das Mähmesser 8 mit der einen Schlupf erzeugenden Bremse, im Beispiel Windflügel 9, vorgesehen.The motor housing 2 is provided with a cable drum 6. At the bottom The end of the motor shaft 7 is the mowing knife 8 with the brake that creates a slip, in the example wind blade 9 is provided.

Bei eingeschaltetem Motor rotiert die Motorwelle 7 mit dem. Mähmesser 8 und den Windflügeln 9 in der einen Richtung, während sich das Motorgehäuse 2 gleichzeitig in der entgegengesetzten Richtung so lange dreht, bis das Anschlußkabel 10 sich strafft. Der Mäher kann mit der erfindungsgemäßen Kabelaufzugsvorrichtung mühelos bewegt werden, ohne daß man Gefahr läuft, das Kabel zu überfahren oder gar mit der eigenen Maschine abzuschneiden und sich dadurch unter Umständen elektrischen Schlägen auszusetzen. When the motor is switched on, the motor shaft 7 rotates with the. Mower knife 8 and the wind blades 9 in one direction, while the motor housing 2 is at the same time rotates in the opposite direction until the connecting cable 10 turns tightens. The mower can effortlessly with the cable elevator device according to the invention be moved without running the risk of running over the cable or even with the cut off your own machine and you may get electric shocks as a result suspend.

Diese Gefahr besteht bei bekannten elektrischen Rasenmähern ohne selbsttätige Kabelaufzugsvorrichtung immer. Die Erfindung verbürgt somit auch in elektrischer Hinsicht eine wesentliche Verbesserung der Betriebssicherheit derartiger Geräte.This risk exists with known electric lawn mowers without automatic ones Cable hoist always. The invention thus also vouches in electrical Consider a significant improvement in the operational safety of such devices.
