Device for Failure Detection on Production Machines

: Linear rolling systems are frequently used in industrial practice for the linear motion of machine parts or mechanical assemblies. Their reliability and prediction of possible failures are, during a production process, highly required to prevent production losses. Unfortunately, common diagnostic systems of linear rolling systems in industrial practice still fail in particular cases. Therefore, we designed an innovative solution for the diagnostic system based on a load-free part with a vibration sensor integrated into a carriage of the linear rolling system. A functional sample of diagnostics was produced, and vibrations measured on a loaded carriage and the diagnostic part in laboratory conditions were compared. Encouraging results were reached by time-domain analysis of measured data. On the diagnostic part, the damage appeared clearly, while on the loaded carriage, we did not observe any signs of damage.
