METHOD OF REALIZATION OF ASYMMETRIC VIBRATION MOTION OF VIBRATORY SYSTEM BY CENTRIFUGAL VIBRATION EXCITER Russian patent published in 1998 - IPC

FIELD: technological vibration equipment, for instance, vibromixers. SUBSTANCE: unbalanced masses of centrifugal vibration exciter rotate at a variable speed, continuously alternating two modes of excitation. According to one of the modes exciting force frequency is approximated to resonance frequency of vibratory system, and according to the other mode - it is averted from resonance frequency. The kinetic energy of the system exceeds the upper specified value and becomes less than that the lower one. The level of kinetic energy is estimated according to vibration amplitude. Asymmetric vibration motion is provided by means of more simple centrifugal vibration exciters. EFFECT: enhanced reliability and durability. 2 cl, 2 dwg
