Bei kleinen Blektrowerkzeugen mit Untersetzungsgetriebe ist es bekannt, das gleichachsig zur Motorwelle liegende Antriebsritzel als Teil für sich auszubilden und es mit der Motorwelle fest zuFor small sheet metal tools with reduction gears it is known that the drive pinion lying coaxially with the motor shaft is a part of its own train and secure it to the motor shaft

verbinden. Diese Bauart hat den Vorteil, daß beim Schadhaftwerden des Kitzels nur letzteres ausgebaut und ersetzt werden muß.associate. This type of construction has the advantage that if the tickle becomes damaged, only the latter is removed and needs to be replaced.

Um bei der bekannten Schraubverbindung des Antriebsritzels mit der Motorwelle eine gute Zentrierung und eine gute Lagerung des Ritzels zu erhalten, wird neuerungsgemäß vorgeschlagen, daß das einstückige Ritzel in bekannter Weise durch einen Gewindezapfen mit der Motorwelle verschraubt ist und daß die beiden zusammenstoßenden Enden von Motorwelle und Ritzel den gleichen Durchmesser aufweisen und beide in dem für die Motorwelle sowieso erforderlichen lager gelagert sind.In order to achieve good centering with the known screw connection of the drive pinion to the motor shaft and to get a good storage of the pinion, it is proposed according to the innovation that the one-piece The pinion is screwed in a known manner by a threaded pin to the motor shaft and that the two abutting ends of the motor shaft and pinion have the same diameter and both in the bearings required for the motor shaft anyway are.

In der Zeichnung ist als Ausführungsbeispiel das vordere Ende eines Elektrowerkzeuges in einem senkrechten Schnitt dargestellt.In the drawing is an exemplary embodiment front end of a power tool shown in a vertical section.

In dem Motorgehäuse, bzw. in dem vorderen Motordeckel 1 ist ein als Teil für sich ausgebildetes Zahnritzel 2 drehbar gelagert. Das Ritzel 2 trägt an seinem inneren Ende einen Gewindezapfen 3» der stirnseitig in eine Gewindebohrung 4- der Motoroder Ankerwelle 5 eingeschraubt ist.In the motor housing or in the front motor cover 1 is a part designed as a part of its own Toothed pinion 2 rotatably mounted. The pinion 2 has a threaded pin 3 »at its inner end is screwed into a threaded hole 4- of the motor or armature shaft 5 at the end.

Die beiden zusammenstoßenden Enden des Ritzels 2 und der Motorwelle 5 besitzen den gleichen Durchmesser und beide Enden sind in dem Innenring 6 eines Wälzlagers 7 gelagert, welches sowieso für die lagerung der Motorwelle erforderlich ist. Aus der Zeichnung ist deutlich ersichtlich, daß beide Enden in die Bohrung des Lagerringes 6 eingreifen.The two ends of the pinion 2 and the motor shaft 5 butting together have the same diameter and both ends are mounted in the inner ring 6 of a roller bearing 7, which anyway for the storage of the motor shaft is required. From the drawing it can be clearly seen that both The ends engage in the bore of the bearing ring 6.

An seinem vorderen oder freien Ende ist das Ritzel 2 mit einem Endzapfen 8 noch in einem weiteren Lager gelagert. Mit 10 ist das auf der anzutreibenden Werkzeugwelle 11 sitzende Zahnrad bezeichnet, in welchesAt its front or free end, the pinion 2 with an end pin 8 is still in a further bearing stored. With 10 the seated on the tool shaft 11 to be driven gear is referred to, in which

das Ritzel 2 dauernd eingreift.the pinion 2 engages continuously.

Im Falle eines Zahnbruches hat man nur nötig, das Ritzel 2 durch ein neues zu ersetzen.In the event of a broken tooth, you only need to replace the pinion 2 with a new one.
