Abstract
Description
Zum Anziehen bzw. Lösen von Schrauben wird häufig ein Steckschlüssel mit einer Ratsche verwendet, um durch einmaliges Aufsetzen des Werkzeugs die Schraube zügig anzuziehen oder zu lösen. An schwer zugänglichen Stellen, oder z. B. bei Muffen ist dieses Werkzeug nicht anzuwenden. Hier wird ein Maulschlüssel eingesetzt. Dieses Werkzeug muß nach einem gewissen Drehwinkel immer wieder neu angesetzt werden. Dieser Vorgang kostet Zeit und kann unter ungünstigen Umständen die Schraube beschädigen. Eine Kombination aus Maulschlüssel und Ratsche dient also der Zeitersparnis und schont die Schraube. A socket wrench with a ratchet is often used to tighten or loosen screws used to quickly tighten the screw by placing the tool once or to solve. In hard-to-reach places, or e.g. B. with sleeves this tool not applicable. A wrench is used here. This tool must be after one certain angles of rotation are always repeated. This process takes time and can damage the screw under unfavorable circumstances. A combination of Open-end wrenches and ratchets therefore save time and protect the screw.
Der Maulschlüssel mit freiem Rückhub ermöglicht das Anziehen bzw. Lösen einer Sechskantschraube bzw. -mutter, ohne den Schraubenschlüssel umsetzen zu müssen. In Gegendrehrichtung ermöglicht der Schlüssel ein Durchrasten der Schraube bzw. Mutter ähnlich einer Steckschlüsselratsche, so daß nach einmaligem Aufsetzen des Schlüssels die Schraube bzw. Mutter komplett angezogen bzw. gelöst werden kann. The open-end spanner allows you to tighten or loosen one Hexagon screw or nut without having to move the wrench. In The key allows the screw or nut to snap into the opposite direction Similar to a ratchet wrench, so that after the key has been put on once Screw or nut can be completely tightened or loosened.
Das Drehmoment wird auf die Schraube mit Hilfe von zwei parallelen Kanten (1; 2) formschlüssig übertragen während die Schraube an einer Fläche (3) im Nutgrund der Schlüsselöffnung anliegt (Fig. 1). The torque is transferred to the screw with the aid of two parallel edges ( 1 ; 2 ) in a form-fitting manner while the screw rests on a surface ( 3 ) in the groove base of the key opening ( Fig. 1).
Das Durchrasten der Schraube im Rückhub wird durch die Form der Maulöffnung erreicht. Beim Zurückdrehen wird der Schlüssel anfangs an den Berührungspunkten zwischen Schraubenflanke (4) und Schlüsselecke (5) sowie Schraubenecke (6) und Schlüsselkante (3) geführt (Fig. 2). The screw snaps into place in the return stroke due to the shape of the jaw opening. When turning back, the key is initially guided at the points of contact between the screw flank ( 4 ) and the key corner ( 5 ) as well as the screw corner ( 6 ) and the key edge ( 3 ) ( Fig. 2).
Nach einem Drehwinkel von ca. 30°, wenn die Schraubenecke (7) die Schlüsselkante (8) berührt, wird der Schlüssel an den Berührungspunkten zwischen Schraubenflanke (4) und Schlüsselecke (5) sowie Schraubenecke (7) und Schlüsselkante (8), übergehend in Schlüsselkante (2) geführt (Fig. 3). After an angle of rotation of approx. 30 °, when the screw corner ( 7 ) touches the key edge ( 8 ), the key at the points of contact between the screw flank ( 4 ) and the key corner ( 5 ) as well as the screw corner ( 7 ) and the key edge ( 8 ), passes over led in key edge ( 2 ) ( Fig. 3).
Nachdem die Schraubenecke (9) die Schlüsselkante (10) berührt, wird der Schlüssel an den Berührungspunkten zwischen Schraubenecke (9) und Schlüsselkante (10) sowie Schraubenecke (7) und Schlüsselkante (2), geführt (Fig. 4). After the screw corner ( 9 ) touches the key edge ( 10 ), the key is guided at the points of contact between screw corner ( 9 ) and key edge ( 10 ) and screw corner ( 7 ) and key edge ( 2 ) ( Fig. 4).
Nachdem der Schlüssel soweit zurückgedreht wird, dass die Schraubenecke (9) die Schlüsselecke (5) passiert, schiebt sich der Schlüssel wieder vollständig über die Schraube und in Drehrichtung kann das Drehmoment wieder formschlüssig übertragen werden (Fig. 1). After the key has been turned back so far that the screw corner ( 9 ) passes the key corner ( 5 ), the key is pushed completely over the screw again and the torque can be transmitted in a positive manner in the direction of rotation ( Fig. 1).
Die Aussparungen (12; 13) entsprechen dem Radius des Eckenmaßes der Schraube und ermöglichen so, daß hier die Schraubeneckenecken (14; 8) der Schraube frei durchdrehen können. The recesses ( 12 ; 13 ) correspond to the radius of the corner dimension of the screw and thus enable the screw corner corners ( 14 ; 8 ) of the screw to turn freely.
Zum Ändern der drehmomentübertragenden Drehrichtung wird der Schlüssel entlang seiner Längsachse (15) um 180° gedreht. To change the torque-transmitting direction of rotation, the key is turned through 180 ° along its longitudinal axis ( 15 ).
Der Grundkörper des Schlüssels (16) enthält eine Nut (17), in die im Bedarfsfalls ein Stützelement (18) (Fig. 5) eingesetzt werden kann (Fig. 6). Durch dieses Element kann der Schlüssel axial auf der Schraube abgestützt werden, was die Handhabung des Schlüssels vereinfacht, da er nicht so leicht von der Schraube abrutschen kann. Die Form des Elementes ermöglicht weiterhin ein seitliches Aufsetzen des Schlüssels. Das Stützelement kann auf beiden Seiten des Schlüssels angebracht werden und wirkt somit in beiden Drehrichtungen. The base body of the key ( 16 ) contains a groove ( 17 ) into which, if necessary, a support element ( 18 ) ( Fig. 5) can be inserted ( Fig. 6). This element allows the key to be supported axially on the screw, which simplifies handling of the key since it cannot slide off the screw so easily. The shape of the element also allows the key to be placed on the side. The support element can be attached on both sides of the key and thus acts in both directions of rotation.
