The new constructive solution is based on the "inverted vibrator" principle (Igumnov et al. 2017; Shilkov et al. 2005).The power pulse, transmitted to the processed medium (fixed obstacle, soil, piles, structures, etc.), arises both due to the thrust against the shoulder of the eccentric shaft and to the drop in the kinetic energy of the operating …

It is a principal object of this invention to provide a variable eccentric drive, of the type indicated, for vibrating conveyors in which this objectionable backlash is eliminated by insuring that the reactions transmitted by the driven member are transmitted entirely into the eccentric shaft to the exclusion of the mechanism for varying the ...

A. One-Times-Rotation Vibration—Electrical 1) Eccentric Rotor: An eccentric rotor, which means the rotor core OD is not concentric with the bearing journals, creates a point of minimum air gap which rotates with the rotor at one times rotational frequency. Associated with this there will be a net unbalanced magnetic force acting at the point of

rest during a displacement cycle under vibration. Most concrete vibrators operate with an amplitude of 0.5 mm to 2.0 mm. Frequency (f) is usually described by the number of vibrations per unit time. 1 Hertz (hz) = 1 vibration per second, or 60 vibrations per minute. Therefore 200 Hz refers to 12,000 vibrations per minute.
