Abstract

The subject of research in this paper is a conveyor drive unit from a conveyor coal transport system that is used by SM "Brod – Gneotino" to SM "Suvodol" (Power plant REK Bitola-Macedonia) because of its existing signs of increased vibrations. Vibration measurements of the drive transporter T5 was obtained to determine the vibration state of the drive unit. Each driveline (electric motor – hydro clutch – gear reducer) has ten measuring points – probes to monitor temperature and ten measuring points – probes for monitoring the vibration of the electric motor bearings and bearings of the gear reducer.

Through proper FFT analysis of the vibration signal that has been obtained by the probes we will determine further conclusions and recommendations regarding the state of the elements of the system and their dynamic stability.
