  • A nonlinear dynamic vibration model of cylindrical

    2021-2-1 · This paper proposes a dynamic model to investigate the vibration response of a cylindrical roller bearing considering skidding. This model considers the frictional forces and the contact forces between rolling elements and races simultaneously. The interactions between the frictional forces and the dynamic responses of rolling bearing when skidding ...

  • Chaotic Dynamics of Cage Behavior in a High-Speed ...

    Considering cage dynamics of high-speed cylindrical roller bearing, the values of cage guidance gap and eccentricity are crucial factors. From the point of view of the manufacturers, the very small cage guidance gap is difficult to obtain owing to the material (brass) of the cage used in high-speed bearing.

  • Nonlinear Dynamic Response Analysis of Cylindrical

    The paper contains a detailed analysis of dynamic behavior of cylindrical roller bearings for unbalanced rotor conditions due to speed variations and internal clearances. The system behaves nonlinearly due to various reasons such as stiffness and damping at the contact points (due to Hertzian contact force between rollers and races), radial internal clearance, and speed associated with unbalanced rotor force.
