Image Acquisition and Image Processing Algorithm for Movement Analysis of Bearings' Rolling Elements

Abstract

Movement analyses of bearings with regard to stable and unstable motion behavior typically investigate the cage whirl. However, some experimental and simulation-based studies exist that analyze the movements of the rolling elements. The majority of these investigations focus on lower shaft speeds. This paper presents an image-based approach for investigating the rolling element motions under high-speed operation condition. A new evaluation algorithm is presented and its suitability is verified first by generic images and afterward by experiments on cylindrical roller bearings.
