FIELD: mechanical engineering; geophysics, seismology, instrumentation engineering, wireless communication and scientific researches in said spheres. ^ SUBSTANCE: according to invention, semispherical recesses are made in solid hard base 1. Ball-shaped bodies 2 and 4 are placed in said recesses. One of bodies 4 is provided with axle 3 and is connected with power source. Body 4 is into vibratory rotation. Spherical bodies 2 in recesses on base 1 vibrate and rotate synchronously in the same direction and at the same angular velocity as body 4. ^ EFFECT: provision of synchronous rotation of several spherical bodies installed on solid hard base. ^ 2 dwg
