VIBRATION TRANSPORTING MACHINE Russian patent published in 2014 - IPC B06B1/00 

FIELD: machine building.

SUBSTANCE: vibration transporting machine includes a working element connected via an elastic connection to a jet part carrying a resonant one-directional vibration device, and shock absorbers of low stiffness; besides, the resonant one-directional vibration device is made in the form of at least a pair of similar parametric vibration exciters mounted on the jet part of the machine and installed so that rotors of inertia elements can be rotated in opposite directions in vertical planes and brought into rotation from independent electric motors, and resonant frequency of the resonant one-directional vibration device is determined as follows: ω=λ₁+λ₂, λ₁=ν·ω, 0<ν<1, where ω - averaged value of partial angular speeds of rotors, λ₁ - effective proper frequency of swinging pendulums of rotors of inertia elements, $${\lambda }_2=\sqrt{C/M_{reduced}}$$ - partial proper frequency of the working element, which corresponds to an opposite-phase shape of one-directional free vibrations, M_reduced=M₁M₂/(M₁+M₂) - reduced mass, C - stiffness of an elastic connection, M₁ - mass of the working element, M₂ - total mass of the machine jet part.

EFFECT: achievement of high stability of a resonant operating mode of a machine at high quality of its vibrating system; as a result, creation of energy-saving vibration transporting machines.
