In the article the construction of the test bench for the durability test of the friction couplings was showed. The properties of the tested tribological pairs are fully described, i.e. chemical constitution, kind of material and the results of the surface topography tests of basic material and with lubricant micropockets. The methodology and scope of the preliminary tests, including observation of course of changes in vibration signals on the housing of the pin-on-disc tester, for different load values and tribological couplings, i.e. with textured or non-textured surface. The vibroacustic research was carried out with industrial unit CSI 2130 by Emerson and with vibration sensor A0760GP. Comparative analysis of vibration signals and amplitude-frequency spectrums was performed for chosen work conditions of the tribological pair. Finally, the possibility to use the measurement of vibration signal to predict a seizure of the tribological pair was described and directions for further research were given.
Keywords: combination of friction, pin-on-disc tester, mashing processes, vibration signals.
