Study of fatigue life of roller bearings type 6204 -2Z
 Poláček, Vojtěch ; Svoboda, Petr (referee) ; Klapka, Milan (advisor)
This bachelor thesis deals with the basic description of produced by fatigue failure of ball bearings. In the paper there is a description of basic diagnostic methods of machine parts. Following there is a study of vibration, their recording and the evaluation concerning bearing lifetime. The aim of the experimental part of the paper is to check the functionality and suitability od the VDT2000 analyzer and VDT Control Center software, both made by company VidiTech, s.r.o. together with the SA67 laboratory experimental stations owned by the Department of Design at Faculty of Mechanical Engineering, which were used for examining the 6204-2Z bearings. The aim of the lifespan exam is to confirm the reliability of the bearing failure warning by the analyzer and to assess the ability to record the first stages of bearing damage.

Temperature Measurement in Technical Diagnostics
 Szmek, Tomáš ; Janečka, Jan (referee) ; Vdoleček, František (advisor)
The purpose of this bachelor’s thesis is to familiarize a reader with possibilities of temperature measurement along with constructions and functions of particular measuring instruments and to present their positive and negative aspects. Both basic contact thermometers used in common life and complex systems (thermovision) employed in the most demanding industrial application are described here. The thesis depicts temperature as a diagnostic value according to which the causes of machinery failures are easily detected and subsequent accidents prevented.
