The vibration generator has an infinitely adjustable eccentric element for adapting the vibrations from nil to max. The vibration generator contains two eccentrics (1,3) mounted coaxial in each other and each firmly connected to a gear wheel (4,7) with inclined teeth. Both gear wheels have the same dia. and opposite teeth inclination. An axially displaceable extension piece (5) contains a fixed double gear wheel which connects the first two wheels (4,7) together. By axially displacing the extension piece the first two gear wheels and thus also the two eccentrics rotate opposite each other.
