Sažetak

The paper addresses the issue of identifying the technical condition of rotating parts with by means of vibrodiagnostics. This method has been developing rapidly in recent years and it is conceived to be used for predicting failure occurrence. This enables us to determine an optimum time to perform machine preventive maintenance. The aim is to determine this point in time for groups of components, such as electric motors, gear boxes, and even combustion engines. In this paper, we focus on monitoring the technical condition of the medium truck bearing box on which we simulate different field conditions. A measuring device, DEWE 50/8, including the DEWEsoft software product of the Dewetron Company, has been used for the actual measurement. Along with the vibrodiagnostics used when determining the technical condition of the bearing box, we have also applied thermography for monitoring thermal changes of individual components. The aim of the research is to determine the moment when a preventive action is to be performed or when to change components before the failure occurs and increases the costs.
