Description
Die Erfindung betrifft eine Schraube mit Magnet für handgeführte Werkzeuggeräte
gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a screw with a magnet for hand-held tool devices
according to the preamble of
Handgeführte Werkzeuggeräte wie beispielsweise Meisselgeräte weisen ein Getriebe und ein Schlagwerk auf. Sowohl das Getriebe als auch das Schlagwerk weisen mechanisch zusammenwirkende, metallische Bauteile auf. Beim Zusammenwirken dieser Bauteile entsteht trotz Schmierung metallischer Abrieb, der sich in einem die Bauteile schmierenden Schmiermittel verteilt, über das Schmiermittel zu Kugellagern und Verzahnungen gelangt und dort zu einem übermässigen Verschleiss sowie zu einer frühzeitigen Beschädigung der Kugellager und der Verzahnungen führt.Hand-held tool devices such as chisels have a gear and a percussion. Both the gearbox and the striking mechanism show mechanically interacting, metallic components. When interacting despite lubrication, these components are subject to metallic abrasion, which is reflected in the Components lubricating lubricant distributed over the lubricant to ball bearings and Toothings arrives and there is excessive wear and tear premature damage to the ball bearings and the gears.
Aus der US-PS 4 810 148 ist eine Vorrichtung zum Sammeln von metallischem, sich im
Getriebegehäuse befindlichem Abrieb bekannt, die aus einer Schraube mit einem
Magneten besteht und in das Getriebegehäuse einsetzbar ist. Die Schraube weist ein
Kopfteil und ein Schaftteil auf, wobei das Kopfteil das Schaftteil radial überragt und das
Schaftteil mit einem Aussengewinde sowie mit einer Ausnehmung versehen ist, die zum
freien Ende des Schaftteiles hin offen ausgebildet ist. Der Drehmitnahme der Schraube
dienen Drehmitnahmeflächen an der Aussenkontur des Kopfteiles in Form eines Aussensechskantes,
an dem ein entsprechendes Eindrehwerkzeug ansetzbar ist.From US-
In die Ausnehmung ragt ein Magnet, der das freie Ende des Schaftteiles um einen Betrag überragt, der grösser ist als die Gesamtlänge der Schraube. Aufgrund der grossen Länge des Magneten ragt dieser ein Stück weit in den Innenraum des Getriebes und wird von dem zirkulierenden Schmiermittel umspült. Auf diese Weise gelangt der metallische Abrieb zum Magneten und bleibt am freien Ende und am Umfang des Magneten haften. A magnet protrudes into the recess and surrounds the free end of the shaft part Exceeds the amount that is greater than the total length of the screw. Due to the large length of the magnet protrudes a little into the interior of the gearbox and is washed around by the circulating lubricant. In this way, the metallic abrasion to the magnet and remains at the free end and on the circumference of the Magnets stick.
Diese bekannte Schraube weist den Nachteil auf, dass beim Entfernen der Schraube der Magnet seitlich am Aussengewinde anschlagen kann. Ein Teil des sich am Umfang des Magneten angesammelten Metallabriebes wird dabei am Aufnahmegewinde des Getriebegehäuses abgestreift und lagert sich dort ab. Beim nachfolgenden Eindrehvorgang der Schraube kann der am Aufnahmegewinde abgelagerte Metallabrieb eine Beschädigung der Gewindeverbindung zwischen der Schraube und dem Getriebegehäuse verursachen oder zu einer Undichtigkeit im Bereich der Gewindeverbindung führen. Einen weiteren Nachteil bildet die grosse axiale Länge des Magneten, der das freie Ende der Schraube überragt. Damit der zusammen mit der Schraube in das Getriebegehäuse eingesetzte Magnet mit beweglichen Teilen des Getriebes nicht kollidieren kann, muss das Getriebe einen zusätzlichen Aufnahmebereich aufweisen, der zu einer grossen Baugrösse des Getriebegehäuses führt.This known screw has the disadvantage that when removing the screw Magnet can hit the side of the external thread. Part of the scope of the Magnet abrasion accumulated on the thread of the Stripped gearbox housing and is deposited there. In the following The screwing in of the screw can be caused by the metal abrasion deposited on the thread damage to the threaded connection between the screw and the Gearbox cause or cause a leak in the area Lead threaded connection. Another disadvantage is the large axial length of the Magnet that extends beyond the free end of the screw. So that together with the Screw inserted into the gearbox magnet with moving parts of the Gearbox cannot collide, the gearbox must have an additional one Have recording area that leads to a large size of the gear housing leads.
Der Erfindung liegt die Aufgabe zugrunde, eine Schraube mit einem Magneten zu schaffen, an dem sich eine grosse Menge an Metallabrieb ansammeln kann, ohne dass sich Metallabrieb am Aussengewinde ablagert und der mit beweglichen Teilen einer Werkzeugmaschine nicht kollidieren kann.The invention has for its object to a screw with a magnet create where a large amount of metal debris can accumulate without metal abrasion is deposited on the external thread and one with moving parts Machine tool cannot collide.
Die Lösung dieser Aufgabe erfolgt durch eine Schraube mit Magnet, welche die im kennzeichnenden
Abschnitt des Patentanspruchs 1 angeführten Merkmale aufweist. Dadurch,
dass die axial gemessene Stärke des Magneten im wesentlichen der vom freien Ende
des Schaftteiles aus gemessenen Tiefe der Ausnehmung entspricht, ist der Magnet
derart in der Schraube einsetzbar, dass eine Oberfläche des Magneten und das freie
Ende des Schaftteiles der Schraube im wesentlichen in der gleichen Ebene liegen. Da
die Schraube den Umfang des Magneten umgibt, kann sich Metallabrieb nur an der in
Eindrehrichtung weisenden Stirnseite des Magneten ansammeln. Beim Herausdrehen
der Schraube aus dem Getriebegehäuse gelangt der Metallabrieb mit dem
Aufnahmegewinde des Getriebegehäuses nicht in Berührung. Eine Ablagerung von
Metallabrieb am Aufnahmegewinde wird verhindert.This problem is solved by a screw with a magnet, which is characteristic of the
Section of
Damit mit Hilfe des Magneten eine grosse Menge an metallischem Abrieb gesammelt werden und an dem Magneten gebunden werden kann, muss dieser eine sehr grosse, mit dem Schmiermittel zusammenwirkende Kontaktfläche aufweisen, an dem das Schmiermittel vorbeiströmt. Die axiale Stärke des Magneten und die entsprechende Tiefe der Ausnehmung können sehr gering sein. Zweckmässigerweise beträgt das Verhäitnis zwischen der Tiefe der Ausnehmung und dem Aussendurchmesser des Schaftteiles 0,1:1 bis 0,2:1.With the help of the magnet, a large amount of metallic abrasion is collected and can be tied to the magnet, it must have a very large, have interacting with the lubricant contact surface on which Lubricant flows past. The axial strength of the magnet and the corresponding one The depth of the recess can be very small. The ratio is expediently between the depth of the recess and the outer diameter of the shaft part 0.1: 1 to 0.2: 1.
Eine formschlüssige Festlegung des Magneten in der Ausnehmung wird vorzugsweise erreicht, indem sich die Ausnehmung zum freien Ende des Schaftteiles hin verjüngt und den Umfangsbereich des Magneten wenigstens teilweise umgreift.A form-fitting fixing of the magnet in the recess is preferred achieved by tapering the recess towards the free end of the shaft part and encompasses the circumferential area of the magnet at least partially.
Bei einer allfälligen Entsorgung der erfindungsgemässen Schraube ist es erforderlich, den Magneten von der Schraube zu trennen. Um diesen Trennvorgang mit einfachen Mitteln bewerkstelligen zu können, ist vorzugsweise im Umfangsbereich der Ausnehmung wenigstens eine Erweiterung angeordnet, die die Ausnehmung radial überragt und zum freien Ende des Schaftteiles hin offen ausgebildet ist. In diese Ausnehmung ist beispielsweise ein Schraubenzieher einsetzbar, der sich beim Verschwenken einerseits an einer zum freien Schaftteil weisenden Oberfläche der Schraube abstützt, andererseits seitlich am Magneten angreift und den Magneten aus der Ausnehmung herausdrückt. Der Magnet kann beispielsweise eine radiale Vertiefung aufweisen, in der die Spitze des Schraubenziehers formschlüssig eingreifen kann. Es ist auch möglich, die Ausnehmung axial derart tief auszugestalten, dass ein Hintergreifen des Magneten durch den Schraubenzieher ermöglicht wird.If the screw according to the invention is to be disposed of, it is necessary to separate the magnet from the screw. To do this separation process with simple To be able to accomplish means is preferably in the peripheral area Recess at least one extension arranged, the recess radially protrudes and is open towards the free end of the shaft part. In these Recess, for example, a screwdriver can be used, the Swiveling on the one hand on a surface facing the free shaft part of the Screw supports, on the other hand engages on the side of the magnet and the magnet out the recess. The magnet can be a radial depression, for example have, in which the tip of the screwdriver can engage positively. It is it is also possible to design the recess axially so deep that it can reach behind of the magnet is made possible by the screwdriver.
Da sich der in der Ausnehmung angeordnete Magnet beim Herausdrücken mit dem Schraubenzieher verkanten und dadurch verklemmen kann, sind vorteilhafterweise dass im Umfangsbereich der Ausnehmung mehrere Erweiterungen gleichmässig verteilt angeordnet. Auf diese Weise ist es möglich, den Magneten mit beispielsweise zwei gegenüberliegend angreifenden Schraubenziehem aus der Ausnehmung zu drücken.Since the magnet arranged in the recess when pressed out with the Tilting screwdriver and jamming it are advantageous that several extensions evenly distributed in the peripheral area of the recess arranged. In this way it is possible to use two magnets, for example to press opposing screwdrivers out of the recess.
Vorteilhafterweise ist die Schraube aus Kunststoff ausgebildet. Die aus Kunststoff ausgebildete Schraube weist ein geringes Gewicht auf und führt zu einem geringeren Gesamtgewicht der Werkzeugmaschine.The screw is advantageously made of plastic. The one made of plastic Screw is light and leads to a smaller one Total weight of the machine tool.
Aus wirtschaftlichen Gründen und damit der Magnet formschlüssig mit der Schraube in Verbindung steht, ist der Magnet vorteilhafterweise mit Kunststoff umspritzt.For economic reasons and thus the magnet with the screw in Connection is established, the magnet is advantageously extrusion-coated with plastic.
