Abstract
Ležajevi, kao sastavni dijelovi mnogih tehničkih sustava i inženjerijskih strojeva, moraju biti u ispravnom stanju kako bi omogućili normalan i kvalitetan rad sustava u cjelini. Dijagnostika ležajeva je od velikog značaja za njihovo kvalitetno i pravodobno praćenje i održavanje. Održavanje ležajeva značajno umanjuje mogućnost zastoja i prekida rada, a time i velikih materijalnih troškova. Uz klasično preventivno i korektivno održavanje, danas sve veću primjenu ima dijagnostika stanja ležajeva, kao oblik preventivnog održavanja. U ovom radu je prikazana podjela ležajeva prema namjeni i konstrukcijskim izvedbama, kao i njihov značaj za kvalitetnu funkciju stroja ili drugog sredstva opreme. Prikazani su oblici i uzroci kvarova ležajeva, koji dovode do njihovog otkazivanja te razne metode za praćenje stanja ležajeva, odnosno dijagnosticiranje mogućnosti pojave kvara. Dijagnostika ležajeva prema stanju provodi se raznim metodama, a jedna od njih je i metoda udarnih impulsa ili SPM metoda. SPM metoda radi na temelju prepoznavanja buke tijekom rada ležaja, koja nastaje prilikom kretanja valjnih tijela po valjnim stazama. U radu su definirani parametri vibracija i njihovo rangiranje prema ISO 10816 normi. U završnom dijelu rada prikazani su i rezultati dijagnostike stanja odabranog ležaja SPM metodom.
Abstract (english)
Bearings, as vital part of many technical systems and engineering machines, must be in sound shape to enable normal and quality performance of the system as a whole. Bearings diagnostics is of great importance for their appropriate and timely maintenance and monitoring. By maintaining them risk of break-down or interruptions of production is significantly reduced, and therefore its costs. Nowadays, state diagnosis of bearings is becoming an important part of the process of the preventive maintenance of machines. In my thesis, classification of bearings according to their use and constructional executions is presented, as well as their significance for a high quality function of machines. Shapes and casuses of bearings malfunction and several methods for monitoring and detecting potential malfunction are covered systematically. One of the many widely-approved diagnostic methods is Shock Pulse Method or SPM method, which is based on the noise of bearings during the work of machine. Noise is created by movement rolling bodies on rolling tracks. In my thesis, parameters of vibration are defined, as well as their ranking according to ISO 10816 norms. In the final part of my thesis, the state diagnosis and results of the chosen bearing is carried out using SPM method.
