Description

Antrieb lür freischwingende Plansichter mittels elektrischen Motors. Die Erfindung betrifft einen elektrischen Antrieb für freischwingende Plansichter, bei denen man bisher schon das Gehäuse mit einem Schwunggewicht versehen hat, um die exzentrische Einstellung des Plansichters herbeizufühxem.. Bisher war aber dieses Schwunggewicht fest mit dem Gehäuse des Motors verbunden. Das Anlaufen des Plansichters machte daher besonders bei größeren Ausführungen Schwierigkeiten, weil der Antrieb bei jedem Plansichter .erst nach einer gewissen Zeit diejenige Umdrehungszahl annimmt, durch welche der Gleichgewichtszustand erreicht wird, welcher der 'Energie des Schwunggewichtes entspricht. Bevor aber dieser Gleichgewichtszustand eintritt, wirkt das feste Schwunggewicht am Gehäuse ungünstig auf den Motor ein und verursacht einseitige Beanspruchungen; das Anlaufen des, Plansichters erfolgt daher nicht stoßfrei.Drive for free-swinging plansifters by means of an electric motor. The invention relates to an electric drive for free-swinging plansifters, where you have already provided the housing with a swing weight to the eccentric setting of the plan sifter. So far this has been the case Flyweight firmly connected to the motor housing. The start of the plansifter therefore made difficulties, especially with larger versions, because the drive with every plan sifter. only after a certain time assumes the number of revolutions, through which the state of equilibrium is reached, which of the 'energy of the swing weight is equivalent to. But before this state of equilibrium occurs, the fixed swing weight takes effect on the housing adversely affects the motor and causes one-sided stresses; the start-up of the plansifter is therefore not smooth.

Diese Nachteile sucht die vorliegende Erfindung dadurch zu vermeiden, daß das Schwunggewicht nicht wie bisher fest mit dem Motorgehäuse verbunden ist, sondern beweglich. Man hat zwar schon bei mechanischem Antrieb von freischwingenden Plansichtern derartige bewegliche Schwunggewichte angebracht. Hier mußte man aber immer eine verhältnismäßig umständliche Übertragung. v an der feststehenden Welle auf das bewegliche Schwunggewicht einbauen. Eine solche Übertragungsrichtung gibt sehr leicht zu Betriebsstörungen Veranlassung, besonders, wenn man berücksichtigt, daß diese Teile durch den Mehlstaub sich sehr leicht verschmieren und in ihrer Beweglichkeit beeinträchtigt werden.The present invention seeks to avoid these disadvantages by that the flyweight is not firmly attached to the motor housing as before, but movable. One already has a mechanical drive of free-swinging Such movable swing weights are attached to plansifters. But here you had to always a relatively cumbersome transfer. v on the stationary shaft install on the movable swing weight. There is such a direction of transmission very easy to cause operational disruptions, especially when one takes into account that these parts are very easily smeared by the flour dust and their mobility be affected.

Bei der vorliegenden Erfindung werden alle diese Nachteile vermieden, und zwar in sehr .einfacher Weise dadurch, daß man das umlaufende Motorgehäuse mit dem pendelnd aufgehängten Ausgleichgewicht versieht. Da dieses Gewicht beim Anlaufen des Motors erst allmählich in seine Endstellung übergeht und erst in dieser zur vollen Wirkung kommt, so läuft der Plansichter stoßfrei an. Einseitige Beanspruchungen, besonders solche des empfindlichen Elektromotors, werden infolgedessen vermieden.In the present invention, all these disadvantages are avoided, and in a very simple way by having the rotating motor housing the pendularly suspended counterweight. Because this weight when starting of the motor only gradually goes into its end position and only in this to When it comes to full effect, the plansifter starts up smoothly. Unilateral loads, especially those of the sensitive electric motor are avoided as a result.

Auf der Zeichnung ist in Abb. i und a ein Ausführungsbeispiel der Erfindung dargestellt. Auf der festen, mit dem Plansichter verbundenenWelle oder dem Zapfens ist ein Anker oder Stator b angeordnet. Um dien herum ist im Gehäuse oder Lagerkörper d der Rotor c des Motors angebracht. Am Lagerkörper d ist das Schwunggewicht e beweglich angehängt, welches bei der Drehbewegung des Lagerkörpers d allmählich in die horizontale Lage e1 ansteigt.On the drawing is in Fig. I and a an embodiment of the Invention shown. On the fixed shaft connected to the plansifter or An armature or stator b is arranged on the pin. Around serving is in the housing or bearing body d attached to the rotor c of the motor. The flyweight is on the bearing body d e movably attached, which gradually with the rotary movement of the bearing body d increases in the horizontal position e1.
