Original Abstract

A major cause of a surface damage of the contact loading machine components (bearings, gears, cams etc.) is the rolling contact fatigue. Various methods of condition monitoring are used to detect damage of these components or specimens in the industry or during testing in laboratories. In the past decades, the acoustic emission technique has been developed into useful condition monitoring method. This paper is focused on the testing of rolling contact fatigue of the metallic materials using acoustic emission method. The methodology of testing, experimental test-rig and preliminary results, are presented in this paper. It can be concluded, that acoustic emission technique can be applied for more accurate rolling contact fatigue evaluation of material.

Czech abstract

Hlavní příčinou poškození povrchu kontakně zatěžovaných součástí (ložiska, ozubená kola, vačky atd.) je kontaktní únava. Pro monitorování stavu těchto součástí nebo vzorků se používají různé metody. V posledních desetiletích se metoda akustické emise vyvinula do vhodného nástroje pro hodnocení kontaktní únavy. Tento článek je zaměřen na zkoušení kontaktní únavy kovových materiálů a je zde popsána metodika testování, experimentální zařízení a předběžné výsledky. Závěrem lze říci, že akustická emise prokázala schopnost detekovat přesněji počátek kontaktního poškození.
