Abstract

Drivable vibration gearing especially to generate straight line, elliptical or screw shaped turning pendulum oscillations with a gear housing and shafts with geared wheels fitted inside it and with centrifugal weights arranged on the side. The vibration gearing includes three coaxial shafts positioned next to each other (2, 3, 4) which project through the gear housing on either side (1) and connected to each other by gear wheels, (8, 9, 10) of equal size and positioned in the same plane the central shaft of which is formed as the drive shaft. Centrifugal weights (5, 7 5a, 7a) are fitted to both the upper and the lower sides of the gear housing (1) at the ends of the two side shafts (2 and 4).
