Arrangement for the excitation of vibrations in load-bearing surfaces

摘要

The rotor unit (10) is enclosed in a cylindrical chamber (9). This rotor unit has scoop-shaped recesses (22) around its circumference. An inlet (11) leads to the chamber (9) in order to allow a pressure medium directed at the scoop-like recesses to be introduced into the chamber. To ensure that the rotor unit (10) has an asymmetric distribution of mass, a number of holes (24) distributed asymmetrically around the axis of rotation are provided in this rotor unit. IMAGE
