Abstract:-The rolling bearings dynamic behavior analysis is a critical condition to determine the machine vibration response. The rolling bearing, with outer ring fixed, is a multi body mechanical system with rolling elements that transmit motion and load from the inner raceway to the outer raceway. The specific construction of a bearing has a decisive influence on its dynamic behavior. The paper defines a vibration model of a rigid rotor supported by rolling element bearings. By application of the defined model, the parametric analysis of the influence of internal radial clearance value and number of rolling elements influence on the rigid rotor vibrations in unloaded rolling element bearing was presented.
Index Terms:-— analytical model, rolling bearing, ball passage frequency, internal radial clearance.
