Image-Based Movement Analysis of Bearing Cages of Cylindrical Hybrid Roller Bearings

Abstract

Movement analyses of bearings focusing on cage motion behavior are often conducted by simulations, typically by investigating the cage whirl. Some experimental studies exist in which a metal cage or a modified one is analyzed with sensors. This paper presents an image-based approach for investigating the cage motion of an injection molded, window-type cage under operation condition. Besides analyses at constant rotational speed, the cage center movement behavior for different accelerations is investigated.
