VIBRATION EXCITER

FIELD: seismic vibration equipment, namely directed oscillation generator to vibration sources for seismic-wave action upon oil-gas deposits from earth surface and in building production. ^ SUBSTANCE: vibration exciter includes first and second weight shafts of each pair that are mutually joined through normally closed clutch. The last has mounted in housing electromagnetic drive with contact-free linear movement pickup, both connected with timing control system. Contact-free frequency and unbalance phase angle pickup of first shaft of each pair is mounted on end of housing in such a way that its disc-code carrier is joined with first weight shaft by means of flexible link. Shaft of rotor of electric motor of electric drive unit is joined by means of flexible link with disc-code carrier of contact-free frequency and unbalance phase angle pickup of second weight shaft of each pair, said pickup is mounted on lid of back bearing assembly of electric motor. ^ EFFECT: enhanced operational properties of vibration exciter due to its simplified design and lowered mass and size. ^ 4 dwg
