- Abstract
Different severity of outer ring defects exist in the roller bearing. When the defects differ from each other distinguishing the defects becomes very challenging. It is very difficult to identify the defects when the signals are in the time domain form. In order to assess the severity of defects the time domain index is proposed in this paper. Firstly, a nonlinear dynamic model of rolling bearing is established. Using this model different severities are simulated. Finally the severity values of the large and small defects are established.
