Description

Schwingungserreger mit zwei entgegengesetzt kreisenden Massen und finit Mitteln zur Phasenverschiebung Die Erfindung betrifft einen Schwingungserreger mit zwei entgegengesetzt kreisenden Massen und- mit Mitteln zur Verstellung -der gegenseitigen Winkellage der Massen während des Betriebes und besteht in der durch den Anspruch bezeichneten und nachstehend an Hand eines Ausführungsbeispiels erläuterten Anordnung, die nur als Ganzes und nicht in ihren Einzelteilen beansprucht wird.Vibration exciter with two oppositely rotating masses and finite means for phase shifting The invention relates to a vibration exciter with two oppositely rotating masses and - with means for adjusting - the mutual angular position of the masses during operation and consists in the through the claim designated and explained below using an exemplary embodiment Arrangement that is claimed only as a whole and not in its individual parts.

In der Zeichnung ist als Ausführungsbeispiel der Erfindung eine zur Verwendung bei hüttclforminaschinen geeignete Einrichtung zur Erzeugung mechanischer Schwingungen dargestellt. Sie besteht aus einem Doppelmotor 2o, der in einem gemeinsamen Gehäuse zwei Ständerbledipakete 2 t hat. Auf einer in den Lagerschilden 22 angebrachten feststehenden Achse 23 sind zwei die Kurzsehluß-. Läufer 24 tragende Hohlwellen 25. gelagert. Auf der einander zugewendeten Seite der Läufer ist je ein Kegelrad 26 angebracht, das durch ein Kegelritzel a.7 mit dem Kegelrad 26 des anderen Läufers gekuppelt ist, so daß die beiden Läufer sich gegeneinander bc-_ wegen. Die beiden Kurzschlußläufer 24 sind mit exzentrischen Gewichten 28 versehen, die so angebracht -sind, daß sie bei der entgegengesetzten Drehung der Läufer beim Durchgang durch die Senkrechte sich an derselben Stelle befinden, so daß die durch die Exzenter hervorgerufenen Stöße in senkrechter Richtung sich verstärken.» Dagegen liegen die exzentrischen Gewichte nach einer Vierteldrehung in der waagerechten Ebene diametral gegenüber, so daß die von ihnen hervorgerufenen. seitlichen Stöße sich ausgleichen.In the drawing, as an exemplary embodiment of the invention, a device suitable for use in hüttling molding machines for generating mechanical vibrations is shown. It consists of a double motor 2o, which has two stator stator packages 2 t in a common housing. On a fixed axle 23 mounted in the end shields 22, two are short-cut. Rotor 24 carrying hollow shafts 25 supported. On the side of the rotor facing each other, a bevel gear 26 is attached, which is coupled to the bevel gear 26 of the other rotor by a bevel pinion a.7, so that the two rotors bc-_ against each other. The two squirrel cage rotors 24 are provided with eccentric weights 28, which are attached so that they are in the same position when the rotors rotate in opposite directions when they pass through the vertical, so that the impacts caused by the eccentrics are intensified in the vertical direction. » On the other hand, after a quarter turn in the horizontal plane, the eccentric weights are diametrically opposed, so that those caused by them. side impacts compensate each other.

Um die Richtung-der resultierenden Stöße zu ändern, ist das RitzeI27 auf einem gegen das Matorge-häusc 2o verdrehbaren I-,ing 2g angeordnet, der durch einen Handgriff 30 verdreht werden kann. Durch Verdrehen des Ringes 2g kann die Stellung der beiden Läufer, bei -denen sich die Gewichte überdecken, beliebig geändert werden. Die hierdurch bewirkte Einstellung der Schlagrichtung kann in vielen Fällen von Vorteil-sein.To change the direction of the resulting impacts, the RitzeI27 arranged on an I-, ing 2g which can be rotated against the Matorge housing 2o and which passes through a handle 30 can be rotated. By turning the ring 2g, the The position of the two runners, in which the weights overlap, can be changed at will will. The resulting adjustment of the direction of impact can in many cases to be an advantage.
