QUASIIMPACT CENTRIFUGAL VIBRATION EXCITER Russian patent published in 1998 - IPC

FIELD: construction industry. SUBSTANCE: quasiimpact vibration mode is organized by centrifugal vibration exciter due to intensive variation of vibration exciter action frequency in characteristic beyond-resonance narrow range of system inherent frequencies. The above-indicated mode is effected by introduction into exciter of "beyond- resonance" signalling device and controllable clutch and brake coupling, which allow intensive variation of action frequency, as well as of flywheel with moment coupling. EFFECT: more intensive production process. 2 cl, 2 dwg
