Abstract
In general, standard of ISO10816 is used for drives of transport mechanisms, determinating general criteria and principles for oscillations of machines. On the basis of evaluative criteria of the standard mentioned above, vibrations of a belt conveyer were measured. By experimental measurements it was found that vibrations of the belt conveyer evidently exceed limiting values defined by the standard. For an improvement of unacceptable state, a consequential solution was suggested. The application of pneumatic flexible coupling in drive of the belt conveyer was one of the possible solution. Consequential experimental measurements for verification of vibrations confirmed that application of pneumatic flexible coupling resulted in decrease of vibrations by 60%. Obtained values of vibrations were lower than limiting values of vibrations required by standard. We can clearly state that by proper application of pneumatic flexible coupling, a positive change in values of vibrations of the belt conveyer was reached, and therefore the belt conveyer meets the evaluating criteria according to the standard of ISO10816. This paper was written in the framework of Grant Project VEGA: „1/0688/12 – Research and application of universal regulation system in order to master the source of mechanical systems excitation”.
