Direct rotation device without reductions for helical dosers (Machine-translation by Google Translate, not legally binding)

摘要

Direct rotation device without reductions for helical feeders, characterized in that the axis of the worm, whose intermittent rotation determines the output of dosed material, is directly connected, without the presence of transmission and speed reduction elements, to the shaft of the rotor of a motor of direct current and low inertia, whose rotation is controlled so that the turns and fractions of return of this rotor coincide with the number of turns or fractions of return that must give in each dosage the worm directly connected .
