Device for generating a circular vibration or a directed vibration with steplessly adjustable amplitude of oscillation or vibration

摘要

The invention relates to a device for generating a circular vibration or in the case of coupling of two parallel, in a synchronized oppositely rotating fundamental waves (10, 60) of a directed vibration (1), wherein each fundamental wave (10) unbalanced weights (12, 13) as well as a coupling (40) between the weights (12, 13), and wherein the vibration amplitude of the excitation force per fundamental wave (10) by means of a displacing unit (30) via the relative rotation of the unbalanced weights (12, 13) to - or separated from one another between a minimum and a maximum value is continuously adjustable. Device according to the invention (1) is characterized in that the unbalanced weights (12, 13) in order to the fundamental wave (10) are rotatably supported thereon, and in that the coupling (40) a with the fundamental wave (10) in a rotationally fixed manner, transmission means (46), which is such that it is in the form of entrainment elements on the unbalanced weights (12, 13) acts, and also with adjustment of the oscillation amplitude of the excitation force a mutual rotation of the unbalanced weights (12, 13) causes.
