Abstract

The vibration generator, designed so that the vibrations can be totally cancelled, has a casing (20) with a a rod (38) protruding top and bottom, mounted in ball bearings housed in corresponding holes in the fixed frame (45) and with two lugs (40) extending outwards, located by a stop to prevent rotation, containing two chambers, each housing a cylinder (25, 24) which can rotate about a spindle near the middle, with a threaded rod (37, 37a) down the middle, so that a piston (36, 36a) inside can slide inside, when the threaded rod is rotated by a bevel drive (31, 32). This drive is in turn driven by a double gear train inside the casing, driven in turn from a variable speed unit. Weights can be added to the top part of the central shaft (38) and a dynamometer device (44) positioned under the bottom part.
