Description

Auswuchtvorrichtung Vorliegende Erfindung betrifft Auswuchtvorrichtungen zur Bestimmung von Wuchtfehlern in rotierenden Körpern, bei denen die dynamischen Kräfte durch nach Phase und Amplitude regelbare elektromechanische Kräfte ausgeglichen werden.Balancing Apparatus The present invention relates to balancing apparatus for the determination of balancing errors in rotating bodies, in which the dynamic Forces balanced by electromechanical forces that can be regulated according to phase and amplitude will.

Bei den bisher bekanntgewordenen Einrichtungen dieser Art wird die Amplitude der elektromechanischen Kräfte mit Hilfe eines passenden elektrischen Instrumentes, z. B. mit einem Amperemeter, bestimmt, wobei der Ausschlag dieses Amperemeters durch eine Eichung in Gramm Wuchtfehler abgelesen werden kann.In the previously known institutions of this type, the Amplitude of the electromechanical forces with the help of a suitable electrical Instrument, e.g. B. with an ammeter determined, the deflection of this Ammeter can be read off by calibration in grams of balancing error.

Gemäß der Erfindung wird vorgeschlagen, die zur Einstellung der AmpIitude vorgesehene Regelvorrichtung (elektrischen Widerstand) unmittelbar als Anzeigevorrichtung auszubilden und derart zu eichen, daß aus der Stellung der Regelvorrichtung bei Abgleichung der Schwingungen des Prüfkörpers sofort die Größe des Wuchtfehlers anzugeben ist. Es hat sich gezeigt, daß die Messung von Stromimpulsen mittels eines Galvanotneters mit Schwierigkeiten verbunden ist, da (las An- und Abschwellen der periodischen Gegenkräfte mit großer Frequenz erfolgt. Bei Anwendung der Vorrichtung gemäß der Erfindung ist man von den Schwankungen der zu messenden Kraft unabhängig. Außerdem wird durch den Wegfall des besonderen Meßinstruments eine wesentliche Verbilligung erzielt.According to the invention it is proposed to set the AmpIitude provided control device (electrical resistance) directly as a display device train and calibrate in such a way that from the position of the control device at Adjustment of the vibrations of the test body to indicate the size of the balancing error immediately is. It has been shown that the measurement of current pulses by means of a Galvanotneters is associated with difficulties, since (read the swelling and declining of the periodic Counter forces with high frequency takes place. When using the device according to Invention one is independent of the fluctuations in the force to be measured. aside from that becomes significantly cheaper by eliminating the special measuring instrument achieved.

Bei der Verwendung eines Schiebewiderstandes zur Einstellung der Größe der elektromechanischen Schwingungen wird dieser am einfachsten in Potentiometerschaltung geschaltet, so daß eine beliebig, von Null bis zum Höchstwert, einstellbare Spannung eingestellt werden kann. Der Schieber des Widerstandes ist mit einem Zeiger verbunden, der sich auf einer Skala. bewegt. Die Stellung dieses Zeigers auf der Skala nach der Abgleichung der mechanischen Schwingungen gibt nach einer entsprechenden Eichung unmittelbar die Größe des Wuchtfehlers an.When using a slide resistor to adjust the size The easiest way to deal with electromechanical vibrations is in a potentiometer circuit switched so that any voltage that can be set from zero to the maximum value can be adjusted. The slide of the resistor is connected to a pointer, which is on a scale. emotional. The position of this pointer on the scale the adjustment of the mechanical vibrations gives after a corresponding calibration directly the size of the balancing error.
