Simulation and Experiment study of ball defects of a two rotors-ball bearing-gear coupling system
MATEC Web of Conferences, 2016 A model of a two rotors-ball bearing-gear coupling systems which considering ball defects on bearing was established. In this model the meshing force of gear coupling and ball defects on bearing was considered.

ANALYSIS OF DISTRIBUTED DEFECT ON OUTER RING OF BALL BEARING UNDER RADIAL LOAD: A THEORETICAL AND EXPERIMENTAL APPROACH [PDF]
Journal of Engineering Science and Technology, 2018 The paper reports development of a theoretical model to study vibration characteristics of the ball bearing. The Lagrangian method is adopted to analyse vibrations generated due to circumferential motions of the ball as well as its contact with an inner ...
