Influence of Inner Ring Roundness Deviation on the Dynamic Characteristics of Cylindrical Roller Bearing

The difference between the maximum and minimum deviation of actual contour relative to ideal circle is roundness caused by uneven temperature wear ring during production operation, which will lead abnormal force. In this paper, a rigid flexible coupling dynamic model cylindrical roller bearing considering inner established study characteristics bearing. And stress contact force raceway or cage under different parameters are studied. It concluded that stress, trajectory largely influenced its deviation. rise with increasing Meanwhile, displacement amplitude increases gradually tends be irregular shape. on increased due existence deviation, but degree has little effect dynamics cage.
