ADJUSTABLE ASYMMETRICAL VIBRATION EXCITER Russian patent published in 1998 - IPC

FIELD: mechanical engineering; vibrating transportation devices. SUBSTANCE: vibration exciter is made as planetary self-balancing mechanism with two fixed central wheels, two carries in form of synchronizing gear wheels with unbalance weight secured on each gear wheel, and two unbalanced planetary gear wheels, one per each carrier. Unbalance weight and planetary wheel on each carrier are installed in diametric opposition. Asymmetry of disturbing force is adjusted by changing static moment of synchronizing gear wheels by shifting of unbalance weights in radial direction with subsequent fixing in any point. Central and planetary wheels are of equal diameter. EFFECT: possibility of adjustment of disturbing force without replacement of design members of vibration exciter. 1 dwg
