Abstract
The invention relates to a method for the control of the chain drive mechanisms of underground working machines and a correspondingly equipped chain scraper conveyor. The invention proposes to filter out a detection signal (S ), representative of the currently arising vibrations of the chain ( ), from the operating data of the main and auxiliary drives (I, II) by means of a detection device ( ), and to take this to an active suppressor ( ), which generates a time-variable control signal (S ) in accordance with a suppressor function, with which, in the frequency range of the vibration of the chain, a change is effected to a control value, e.g. (S ) for the closing pressure adjustment of a multiple disc clutch ( ) of at least one drive unit for the suppression of vibration by the abstraction of energy from, or the introduction of energy into the chain ( ).
