This study analyzes the impact of surface defect on rolling ball on the bearing vibration and noise, in working conditions. It resorts to an experimental approach, based on the DOE. Artificial defects were obtained on different sets of balls, assembled in axial bearings, which were tested at constant spin speed, on a dedicated test rig. The test rig was expressively designed to detect the ball vibration, with respect to its geometric and physical characteristics, and to quantify the impact on bearing noise and vibration, as well as their mutual interaction.

Abstract
This study analyzes the impact of surface defect on rolling ball on the bearing vibration and noise, in working conditions. It resorts to an experimental approach, based on the DOE. Artificial defects were obtained on different sets of balls, assembled in axial bearings, which were tested at constant spin speed, on a dedicated test rig. The test rig was expressively designed to detect the ball vibration, with respect to its geometric and physical characteristics, and to quantify the impact on bearing noise and vibration, as well as their mutual interaction.File | Dimensione | Formato | |
