Abstract

The present invention concerns a drive unit for generating a reciprocating driving motion for driving movable machine elements in relation to fixed surroundings. In connection with the invention, it is relevant to speak of oscillatory motion, and in connection herewith vibrators. The invention is focused on the use of such resonance springs, and it is based on consideration of the fact that the effect of the these springs is also dependent on a reactive force, namely that the spring has a fixed, supported end part in relation to which the free end of the spring may move for performing the actual drive motion. By the invention it is realised that it is possible to minimise or to completely eliminate the reactive force on the fixed part by utilising an "opposed resonance system" which substitutes a fixed rear support of the active resonance spring and work in opposite phase to this with approximately corresponding resonance characteristic. The total device will depend on working with a co-ordinated opposed phase activation of the two systems, which is, however, easily achieved, e.g. by using an interposed vibrator or a driven rotating eccentric which via interposed connecting drive springs may transmit oppositely directed drive forces to the oscillating mass bodies.
