Description
Bei elektrischen Handwerkzeugen wird häufig die Forderung erhoben, den Trieb (Ritzvel) an der Motorwelle auswechselbar zu befestigen, um z. B. bei Schadhaftwerden des Ritzels ein neues einsetzen zu :können Hierzu hat man die Welle mit einer Bohrung versehen, in welche der Zapfen des Ritzels eingepreßt wurde: Die Sicherung gegen Verdrehen erfolgte durch einen Keil, der zugleich auch für .die Kraftübertragung dient. Hierzu ist in der Bohrung der Welle und indem Zapfen eine Nut vorgesehen. Diese Art der Befestigung ist insbesondiere für Wellen mit geringem Durchmesser nicht geeignet, da durch die Nut der Querschnitt der Welle verringert wird und außerdem die Herstellung der Nut in der Welle schwierig ist.In the case of electric hand tools, the requirement is often raised to attach the drive (Ritzvel) to the motor shaft interchangeably in order to z. B. at If the pinion becomes damaged, a new one can be used: You can use the shaft for this provided with a hole into which the pin of the pinion was pressed: The Securing against twisting was done by a wedge, which at the same time also for .die Power transmission is used. For this purpose, one is in the bore of the shaft and in the pin Groove provided. This type of attachment is particularly suitable for shafts with a low Diameter not suitable, as the cross-section of the shaft is reduced due to the groove and also the production of the groove in the shaft is difficult.
Es ist bereits bekannt, zur Verbindung verschiedener Teile, z. B. des Kolbenzapfens .mit dem Kolben von Verbrennungsmaschinen, in Bohrungen bzw. Ausnehmungen der zu verbindenden Teile eingreifende Klemmkörper, wie Kugeln, Zylinder od. digl., vorzusehen. Diese Klemmkörper dienen bei den :bekannten Ausführungen dieser Art aber nur zur Sicherung gegen ein unbeabsichtigtes Lösen der beiden Teile und sind nicht dazu bestimmt odergeeignet, namhafte Kräfte zwischen diesen Teilen zu übertragen.It is already known to connect various parts, e.g. B. of the piston pin .with the piston of internal combustion engines, in bores or recesses the parts to be connected engaging clamping bodies, such as balls, cylinders or digl., to be provided. These clamping bodies are used in the known designs of this type but only to secure against unintentional loosening of the two parts and are not intended or suitable to transfer significant forces between these parts.
Die Erfindung schafft demgegenüber eine sehr einfache und leicht lösbare und dabei auch zur Kraftübertragung geeignete Klemmverbindung zur auswechselbaren Befestigung des eingepreßten Trieibzapfens eines Ritzels in der Bohrung der Motorwelle von elektrischen Handwerkzeugen. Eine solche Anordnung gemäß der Erfindung besteht darin, daß in an sich bekannter Weise der Zapfen des Ritzels eine radiale Ansenkung und die Welle eine entsprechend radiale Bohrung zur Aufnehme des Klemmkörpers besitzt, der durch den Innenring eines :darüber aufgebrachten Kugellagers festgehalten wird. Der Klemmkörper kann dabei beispielsweise die Gestalt einer Kugel, eines Zylinders mit kegeligem Ansatz od. dgl. haben.In contrast, the invention creates a very simple and easily detachable one and also for power transmission suitable clamping connection to the exchangeable Fastening of the pressed-in drive pin of a pinion in the bore of the motor shaft of electric hand tools. Such an arrangement according to the invention exists in that the pin of the pinion has a radial countersink in a manner known per se and the shaft has a corresponding radial bore for receiving the clamping body, which is held in place by the inner ring of a ball bearing mounted above it. The clamping body can, for example, have the shape of a sphere or a cylinder with a conical approach or the like.
In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt, und zwar sind .die gleichen Teile in den Figuren mit .den gleichen Bezugszeichen versehen. In den Fig. I und 2 isst mit I die Welle bezeichnet, welche an ihrem einen Ende eine axiale Bohrung 2 besitzt. In diese Bohrung wird der Zapfen 3 eines Ritzels 4 eingepreßt. Der Zapfen 3 besitzt, wie aus Fig. 2 und 3 hervorgeht, eine radiale Ansenkung 5, die Welle eine entsprechende Bohrung 6. Außerdem ist am Ende der axialen Bohrung 2 eine zweite Bohrung 7 vorgesehen, durch welche beim Einpressen des Zapfens die Luft entweichen kann. In der ersten Bohrung liegt eine Stahlkugel 8, die durch einen auf der Welle aufgezogenen Ring 9 (im Ausführungsbeiden Lagering des Kugellagers Io) festgehalten wird. Mit II ist in Fig. I eine Fettschnecke bezeichnet. Ist das Ritzel schadhaft geworden, wird das Kugellager bzw. der Sicherungsring der Stahlkugel.abgezogen und der mit einer Ansenkung versehene Zapfen eines neuen Ritzels eingepreßt, die Kugel wieder eingelegt und das nebenbei zur Blockierung der Kugel dienende Kugellager oder ein entsprechend anderer Ring, eine Buchse, Radnabe oder ähnliches wieder aufgezogen.In the drawing, two exemplary embodiments of the invention are shown, The same parts in the figures have the same reference numerals Mistake. In Figs. I and 2, I denotes the shaft, which at its one Has an axial bore 2 at the end. The pin 3 of a pinion is in this hole 4 pressed in. The pin 3 has, as can be seen from FIGS. 2 and 3, a radial one Countersink 5, the shaft has a corresponding hole 6. In addition, at the end of the axial Bore 2 a second bore 7 is provided through which when the pin is pressed in the air can escape. In the first hole is a steel ball 8, which through a ring 9 pulled onto the shaft (in the embodiment both bearing rings of the ball bearing Io) is held. A fat snail is designated by II in FIG. Is this If the pinion becomes damaged, the ball bearing or the retaining ring of the steel ball will be pulled off and the countersunk journal of a new pinion is pressed in, the The ball is inserted again and the ball bearing, which is also used to block the ball or a correspondingly different ring, bushing, wheel hub or the like is pulled back on.
Bei der Anordnung nach Fig.4 ist das Ritzel hinterdreht, so daß ein Einstich (Ringnut) 12 entsteht und das Herausziehen des das Ritzel tragenden Zapfens aus der Welle leicht vorgenommen werden kann.In the arrangement according to Figure 4, the pinion is turned back, so that a Recess (ring groove) 12 is created and the pin carrying the pinion is pulled out can be easily made out of the shaft.
Die Anordnung nach der Erfindung kann nicht nur für die auswechselbare Befestigung des Triebzapfens eines Ritzels an einer Welle angewendet werden, sondern auch beispielsweise bei der axialen Verlängerung zweier Wellen, bei der der Zapfen einer Welle in die axiale Bohrung der anderen Welle eingesetzt wird. Die Erfindung ist auch anwendbar für die Befestigung von Zapfen an feststehenden Wellen (Achsen).The arrangement according to the invention can not only be used for the interchangeable Attachment of the drive pin of a pinion to a shaft can be used, but also, for example, with the axial extension of two shafts in which the journal one shaft is inserted into the axial bore of the other shaft. The invention can also be used for fastening pins to fixed shafts (axles).
