BeschreibungDescription

Auf dem Markt für Schraubgeräte, die auf Basis von Drehmoment Muttern und Schrauben andrehen, gibt es sogenannte elektrisch betriebene Kraftschrauber, die für Drehmomentbereiche zwischen 500 Nm und 10.000 Nm vorgesehen sind.On the market for screwing devices that tighten nuts and screws based on torque, there are so-called electrically operated power screwdrivers that are designed for torque ranges between 500 Nm and 10,000 Nm.

Hierbei wirkt in den meisten Fällen ein &Egr;-Motor über ein Getriebe auf ein Planetengetriebe, das die Leistungsabgabe des Motors vervielfacht.In most cases, an E-motor acts via a gearbox on a planetary gear, which multiplies the power output of the motor.

Ein kontrollierter Anzug erfolgt über die Messung der Spannung am &Egr;-Motor, die im Verhältnis zum Drehmoment in einer elektronischen Steuerung gesetzt wird.A controlled tightening is achieved by measuring the voltage on the Egr; motor, which is set in relation to the torque in an electronic control system.

Der Schrauber schaltet ab bei Erreichen eines Widerstandes &khgr;; &khgr; entspricht dem gemessenen Wert Y / Drehmoment.The screwdriver switches off when a resistance &khgr; is reached; &khgr; corresponds to the measured value Y / torque.

Diese Maschinen sind beliebte Werkzeuge im Stahlbau u. a.. Gewöhnliche Steuerungen sind hierbei enormen Beanspruchungen ausgesetzt durch Feuchtigkeit, Schlageinwirkung, Verkantungen innerhalb von Stahlträgern u. a.. Der Antriebsmotor kann hierbei beschädigt werden. Abgebrochene Umschalthebel für Richtungsvorwahl, gebrochene Gehäuse und die an der Oberseite des Antriebs angebrachten Tipptasten-Stellwerke, Rändel-Einstellräder und Drehmoment-Vorwahlschaiter sind häufige Ausfallursachen.These machines are popular tools in steel construction, among other things. Ordinary controls are exposed to enormous stresses due to moisture, impact, tilting within steel beams, etc. The drive motor can be damaged in the process. Broken switch levers for direction pre-selection, broken housings and the touch button switch boxes, knurled adjustment wheels and torque pre-selection switches attached to the top of the drive are common causes of failure.

Die erfindungsgemäße Schraubvorrichtung (1) ist in der Zeichnung dargestellt und besitzt eine über ein Tipptasten-Stellwerk (3) schaltbare Steuerungselektronik wobei Stellwerk und Steuerungse-The screwing device (1) according to the invention is shown in the drawing and has a control electronics that can be switched via a touch-button switch (3), whereby the switch and control electronics

lektronik im Gegensatz zur bisherigen Technik am Griff (2), einem „Spatengriff", angeordnet sind..In contrast to previous technology, the electronics are arranged on the handle (2), a "spade handle".

Somit wird die Möglichkeit der Beschädigung dieser Tip-Einstellung durch Schlageinwirkung oder Verkantung von oben ausgeschlossen. This eliminates the possibility of damage to this tip setting through impact or tilting from above.

Die Steuerungselektronik ist voll vergossen gegen thermische Beanspruchung im Griff des Motors eingebaut.The control electronics are fully encapsulated to protect against thermal stress and are installed in the handle of the motor.
