Abstract
This paper presents the vibrodiagnostic test rig for analyzing the condition of rolling bearings. The rollingbearings are the most widespread mechanical elements, which are also considered critical elements within the mechanical assembly. Typically functionality, reliability and exploitative properties of the entire machine system depend on the functional capabilities of rollingbearings. The paper presents a design of a rolling bearings vibrodiagnostic test rig, which allows for simulating loads that are close to real loads during the operation of bearings, as well as a measuring instrument VibroLog, which is used for the acquisition and display of measured data. The newly developed measuring instrument VibroLog modular device for measuring and analysis of several diagnostic bearing parameters: vibration, speed, temperature and sound pressure. With this modularity, it enables easier diagnostics and speeds up the process of finding problems and faults in bearings.
