Sažetak:
The purpose of this study was to investigate the existing maintenance models of web offset presses, and to propose the method which increases the reliability of the printing press exploitation, but does not require big investments. Doctor motors allowed constant monitoring by measuring instruments, which allowed insight in current status of motors at any time, so they could be repaired or replaced before malfunction. The effective vibration speed (vRMS) was measured a few times during the year 2006. Standard ISO 2372-1974 (E) defines values and boundaries of the effective vibration speed (vRMS). Results of measuring effective vibration speed indicated the emersion of nuisance energy with deterioration. To determine the state of bearings, and check if they cause the increase of effective vibration speed, an envelope analysis - FFT of the acceleration specter is conducted. This decreases the probability of motor malfunction and greatly increases the reliability of the whole system.
