VIBRATION EXCITER OF INERTIAL MOTION Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: exciter has case 1, motor of drive 2, units of inertia-pulse converter 3, and mean 4 for connection of the converter with the case. The converter has one common crankshaft 5. Each crank of the crankshaft is coupled with three links 8,9,10 through link stones 7. The links carry working weights 11,12,13. Working weight 12 is interposed between adjacent working weights 11,13. Weights 11 and 13 are equal, and weight 12 is twice weight 11 or 13. The crank coupled with link 9, which carries weight 12, is turned by 180 deg in the unit about the cranks coupled with lesser weights through links 8,11. The connection mean 4 can be flexibly deformed. Each link has rocking axle 14 secured in case 1. Crank (eccentric) shaft 3 is balanced with counterweights 15. EFFECT: improved design. 6 cl, 7 dwg
