Analysis of the development of structural changes in vibration signals of rolling bearings under shaft misalignment
Abstract
Shaft misalignment is considered as a defect which forms additional forces and reaction moments in the cage area creating a preload on the shaft and bearing and also changing the spectral structure of the vibration signal. These structural changes were analyzed, and typical diagnostic features for assessing the development of damage in the bearing by the methods of periodically non-stationary random processes were summarized. The results of processing and analysis of vibration acceleration signals obtained during laboratory tests on a vibrating stand of the BBC-R 6205 2RS/P6 bearings at different angular misalignment values were presented.
