Possibilities of Using Vibrodiagnostics for Evaluating the Technical State of Roller Bearings
Original language description
This paper focuses mainly on the vibrodiagnostics of rolling bearings and the specification of their damage, and illustrates how to determine specific failure frequencies. Following the analysis of the measured signals we try to find causes of the damageoccurrence. For the analysis the methods of a Fast Fourier Transform and envelope detection have been chosen. The paper addresses the aspect of the effective root-mean-square value of a signal (RSM) which might be used for evaluating the state of a bearing during longer-term observation. The practical part of the research was carried out in a laboratory where a place for measuring vibrations including relevant software equipment had been established for this purpose. Vibration sensors are one of the main components of a measuring device which has been described in the paper and modelled in Autodesk Inventor to have a better idea of it. For the measuring itself the equipment DEWE 50-USB-8 of the DEWETRON company as well as DEWEsoft were
