VIBRATION EXCITER FOR INERTIA PROPELLER Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: exciter has housing 1, inertia-pulse converter 3 of periodic action to one- directed effort, member 4 for connection of the housing with converter 3, and drive 2. The inertia-pulse converter is constructed as one or some units of the converter mounted on one common or two parallel common crankshafts 5 coupled with drive 2. When the number of the units N is grater than unit, the cranks of adjacent units are turned by 360/N deg with respect to each other about the rotation axis in the same direction. The units can be mirror images of each other and symmetric about the plane perpendicular to the rotation axis. The unit of the converter is made up of working weights 11,12, secured to the ends of rocking links 8,9,10 connected with the cranks of shaft 5 and mounted for alternative motion with respect to each other in the opposite directions. The member 4 for connecting the housing with the converter is made for flexible deformation and coupled with links 8,9,10 from one side and with housing 1 from the other side. Member 4 for connection of the housing with converter 3 can be constructed as spring 14 (stretching, compression, torsion, bent). EFFECT: improved design. 6 cl, 7 dwg
